Cleanroom molding is the technique part producing plastic parts in a controlled environment to limit the danger of particle contamination. Several businesses require specialized components fabricated in a cleanroom environment for increased safety and precaution.

It is most typically utilized in medical injection molding and the manufacture of other medical products.

Machines inside cleanrooms must be checked and cleaned regularly. Floors, walls, tools, and workstations must be kept sanitary and sterile during production and thoroughly cleaned afterwards. Cleanrooms must also be adequately ventilated with filtered air.

Cleanroom molding employees are required to wear protective clothing such as hairnets, gowns, gloves, and shoe covers. Any specific clothing worn inside the cleanroom is not permitted to be worn outside the facility. A separate clean gowning space is usually provided. In addition, Seaskymedical have an isolated area that meets the clean room injection molding requirements.

The process of maintaining and controlling clean room protocol and clean room certification and accreditation for medical injection molding is extensive. To stay in compliance, clean room injection molders must pay close attention to several elements, including


Cleanroom settings decrease contaminants and dust particles daily to avoid impacting product quality and reliability. This is crucial for companies who wish to develop trust in medical items by guaranteeing that their standards meet all health and safety criteria.

Increase the Probability of an Injection Machine

Airborne contamination is a major problem in the medical injection sector. The cleanroom system addresses this by carefully controlling air flow rates and direction and compression, temperature, and humidity levels, thereby boosting machine life and performance.


The sterile injection molding in a clean room eliminates contamination. This is by using positive pressure to prevent non-filtered air from flowing back into the cleanroom via the exhaust terminals. Ensuring that air pollutants do not accumulate on small components, affecting their capacity to function.

In order to keep the surrounding area sanitary, it is essential to manufacture products using clean room molding. Clean room molding is an example of a manufacturing process that takes place in a controlled environment. This ensures that the space is sanitary and devoid of any harmful substances. When manufactured goods are molded in a clean room, it helps to ensure they are free of contamination.

Utilizing molding produced in a clean room comes with several advantages. It is of assistance in the process of establishing a sterile environment. This is of utmost significance in regard to medical equipment. Another advantage is that it lessens the likelihood of contamination spreading from one area to another. 

Cross-contamination is when one product becomes tainted as a result of another product becoming tainted. If the products are not kept in different locations throughout the production process, this is possible. By separating different types of products from one another, clean room molding lowers the likelihood of contamination spreading.

Molding in a clean space presents a wide variety of difficulties. One potential drawback is that the cost can be high. This is because the essential tools and components could come at a high price. In addition, maintaining a clean and sanitary working environment might be challenging.

Medical device injection molding, it must be kept as clean as possible when producing a plastic part, such as an implantable medical device. A sterile environment is required for the production of such a part. This type of environment is known as a clean room. 

A clean room is a controlled environment in which the amount of airborne contaminants per unit volume, such as dust and other airborne germs, is reduced to reduce the possibility of contamination. These particles are filtered using a High-Efficiency Particle Air (HEPA) filter, which filters the air before entering the cleanroom and is changed multiple times per hour, according to the cleanroom class defined by the International Standard Organization (ISO) 14644-1.

Clean rooms are kept under positive pressure to allow particles to escape from the cleanest to the least clean section in order to preserve a product free of pollutants. However, some cleanrooms, such as quarantine stations and chemical analysis facilities, are kept under negative pressure to keep nothing out of the cleanroom.

Plastic parts are produced in a separate room that has been adjusted to decrease the possibility of contamination from dust or other particles. This is referred to as cleanroom molding. Parts must frequently be created in sterile medical, pharmaceutical, and biotechnology environments.

Before getting into cleanroom molding, it is critical to grasp the distinction between an ISO 7 and an ISO 8 cleanroom.

Clean rooms are classified into nine sorts, or classes, with Class 1 being the most sterile and Class 9 being the least sanitary. Most plastic injection molding in a cleanroom setting occurs in Class 7 or Class 8 cleanroom. 

A more sterile cleanroom environment may be required for the plastic item with a very low tolerance for foreign object debris, such as a lens used in a thermal imaging weapon scope. Understand more what is the difference between ISO 7 and ISO 8 clean room for plastic injection molding as follows:

ISO 7 Cleanrooms for Plastic Injection Molding

A Class 7 Cleanroom is a contained injection molding environment with solid walls that separates it from the rest of the production floor. Air is constantly changed, cleaned, and metered to maintain ISO 14644-1 compliance for particulates.

  • There can be 352,000 particulates >= .5 micrometer per cubic meter of air
  • There can be 83,200 particulates >= 1 micrometer per cubic meter of air
  • There can be 2,930 particulates >= 5 micrometers per cubic meter of air

In order to retain its classification, a third-party agency inspects and calibrates the Class 7 Cleanroom regularly (either annually or biannually, depending on the facility).

ISO 8 Cleanrooms for Plastic Injection Molding

Class 8 Cleanroom requirements are less stringent than Class 7 Cleanroom requirements. Molding equipment is surrounded by movable tenting on the shop floor of a Class 8 Cleanroom. To meet the ISO 14644-1 particle standards, a positive airflow is maintained, as in Class 7.

  • There can be 3,520,000 particulates >= .5 micrometers per cubic meter of air
  • There can be 832,000 particulates >= 1 micrometer per cubic meter of air
  • There can be 29,300 particulates >= 5 micrometers per cubic meter of air

ISO 7 and ISO 8 cleanrooms require low-risk situations, such as general surgery, gynecology, patient preparation/awakening corridors, critical care and resuscitation, and so on. Many checks should be done to assure environmental control, including verification of instrument calibrations, treatment system adjustment, airflow, air unidirectionality (when there is a filtering plenum), noise, and the smoke test.

Take into account the following aspects of the desired environment:

To ensure air quality, Class 7 and 8 cleanrooms use positive airflow to maintain clean air and a small number of particles.

Electric machinery, rather than hydraulic engines, should be used in most cleanroom conditions. The number of particles in the air would be reduced as a result.

Requirements for Coverage:

Engineers and operators must be completely covered when entering an ISO 7 cleanroom. Shoe covers, full-body garments, and low-cost covers are examples. Coverage requirements may be stricter in eighth grade.

Packaging Restrictions: Cardboard and plastic-coated plastic packaging are common in cleanrooms. Particle-generating packaging, such as some corrugated board materials, is not permitted in cleanrooms.

What Are the Clean Room Injection Molding Requirements

Molding requirements for a clean room differ from those of a typical injection molding floor. This section explains the basic requirements for an injection molding clean room.

Loading System

All components entering the cleanroom, save raw materials, must pass through a negative pressure chamber. All dust particles will be removed from this location before entry to the cleanroom is granted.

Finished goods manufactured and sealed in the cleanroom are also transported using this loading system.

Material Drying Equipment

Material drying equipment is kept outside of the clean room. It is sealed to keep contamination out of the cleanroom and requires little to no maintenance.

Because loading the dryers, testing the material, and removing it from the cleanroom pose contamination risks, the material drying equipment must be stored outside. As a result, the complete system is housed in a safe environment outside.

The drying equipment is linked to the feeding apparatus. Furthermore, an annual maintenance inspection is undertaken to ensure that there is almost no danger of contamination within the cleanroom.

Cooler System 

Water must be used to cool injection molding machines when they are in use. The chiller that brings water to the proper temperature is located outside the cleanroom. Because the chiller device draws air from outside and warms it, it is ideal to be out of a cleanroom environment. As a result, only pipes delivering cold or hot water are meant to fit.

The cold water enters the cleanroom, cools the machine or mold, and then the chilled, warm water exits the cleanroom. The pipes allow for chilling without putting contamination at risk.

Feeding System

In most cases, an injection machine can be fed by hand, especially for very small production runs or sampling activities. In most high-volume production, a feeder is attached to the machine and sucks plastic into the machine. The feeder is frequently in close proximity to the material dryers.

Because dryers are prohibited in a cleanroom, the plastic resin must be transferred to the machines via pipes. The pipes will transfer the material directly into the machine from the ceiling.

Electric vs Hydraulic Machines

In clean rooms, electric machines often replace hydraulic machines to prevent the development of airborne particles. This is because hydraulic machines have fewer motors, joints, gear mechanisms, and subsystems.

On the other hand, electric machines lack the hydraulic system’s hoses, filters, tubes, and valves. As a result, electric machines reduce the possibility of contamination. This allows for a contamination-free injection machine loading technique.

Positive Pressure Airflow

Positive Pressure shows that the air pressure within the clean room is higher than the outside air pressure. A positive pressure air flow is created by pumping clean, filtered air from the ceiling into the cleanroom.

When keeping contaminants from entering the cleanroom is a primary priority, positive Pressure is often used. If there is a leak, clean air will be ejected rather than unfiltered air entering the cleanroom.

Negative Pressure Airflow

Air is filtered out inside a cleanroom with negative pressure, resulting in lower air pressure than outside. Every window, door, and other opening is completely sealed. As a result, the Pressure in the area lowers, allowing outside air to enter the cleanroom. Negative Pressure is the top priority when stopping contamination from leaving the cleanroom.

Criteria for Selecting a Medical Injection Moulding Cleanroom Environment

  • Examine the cleanroom class criteria for the project:

Class 8 cleanrooms are prevalent in injection molding factories, but if consumers prefer to make implantable medical devices, they must do so in a Class 8 cleanroom. As a result, cleanroom class requirements must match the consumer’s project specifications.

  • Check to see the product that can be manufactured, assembled, and packaged in a cleanroom:

To ensure that the plastic component is as clean as possible, pick a manufacturing partner who can not only mold but also assemble and package their product in a cleanroom. This ensures that the plastic component is clean.

  • Check to see if they can manufacture intricate plastic parts:

The cleanroom capabilities of an injection molding company can vary, but if the project requires the manufacture of complex plastic parts with difficult tolerances, the consumer must ensure that the injection molding company is capable of maintaining tight tolerances. This understanding is essential to ensure that each plastic component is not only clean but also of high quality.

Plastic Materials Used in Clean Room Injection Molding

Polyethylene terephthalate

Polyethylene terephthalate (PET) is one of the most extensively used polymeric materials in the health care business. This is due to its biocompatibility, high homogeneity, mechanical strength, and resistance to chemicals and/or abrasion. 

While bacterial adherence is dependent on surface properties. Such as surface charge and energy, hydrophilicity, and surface roughness; antimicrobial compounds attached to the surface can have a biocidal influence by slowing bacterial growth (bacteriostatic) or killing bacteria (bacteriocidal) (bactericidal). 

As a result, it is widely accepted that imbuing PET surfaces with antibacterial properties will benefit the prevention of infectious diseases. For this purpose, various modification procedures have been reported.

In clean room injection molding, PET is melted and injected into a mold to create the desired shape. After that, the plastic is cemented by cooling the mold. Injection molding is a fast and efficient way to mass-produce components from a single mold. Clean room injection molding is used in businesses that require extreme cleanliness, such as the medical field. This approach removes contaminants that could interfere with delicate processes.

High-density Polyethylene

When it comes to High-density polyethylene (HDPE), this is a versatile polymer used in a variety of industries and applications. It is also a cost-effective thermoplastic material with numerous applications in clean rooms. One of the most common applications for HDPE is injection molding in a clean room. In clean room injection molding, HDPE is used to create parts and products that are free of contaminants and pollutants. This type of molding is typically used in industries where product purity is critical, such as the medical, food, and semiconductor industries.

The properties of HDPE make it an appropriate material for clean room injection molding. Because HDPE is a nonporous polymer, it does not absorb contaminants like porous materials. HDPE is also chemically resistant, making it ideal for usage in industries where harsh cleaning agents are used. Furthermore, HDPE has a low moisture absorption rate, which inhibits mold and germ formation.

Injection molding in a clean environment is a precise technique requiring careful planning and execution. The first step in the process is to choose the best HDPE resin for the job. The resin must be compatible with the manufacturing technique as well as the end product criteria. Following the selection of the resin, the mold must be designed. The mold must be designed to meet the application and HDPE specifications.


As a result of its low melting point, polypropylene can be injected molded using the same processes that are typically used for injection molding. It is a material that is not only lightweight but also long-lasting and biodegradable. Because of this, it is an excellent choice for use in producing goods in clean rooms.

Clean rooms are specialized laboratories used in the conduct of scientific and medical research. Within these labs, the materials that are employed are handled in compliance with stringent safety requirements. The operation of clean rooms at extremely high temperatures and pressures is required in various industrial processes, including the fabrication of semiconductors.

Before it can be utilized in a clean room, polypropylene has to go through a precise processing step first. To begin, the plastic must be submerged in a solvent for a considerable amount of time. This eliminates any contaminants that may have the potential to make the clean space unsanitary. After that, the plastic must be subjected to extremely high temperatures to be prepared for injection into the mold. This guarantees that the plastic melts all the way through and can be injected into the mold without difficulty.

ABS Plastic

The thermoplastic polymer known as ABS plastic is often processed using injection molding. Because it is resistant to both chemicals and impacts, it is an excellent choice for a diverse range of applications in the industrial sector. ABS plastic has a wide range of applications and is commonly seen in places such as computer keyboards and bumpers on vehicles.

Injection molding in a clean room is the process of injection molding in an environment with very few impurities. This is done to develop goods that are free of flaws and pollutants in their production. To reach this level of cleanliness, specialized equipment and procedures are utilized throughout the process.

The first step in clean room injection molding is to choose the appropriate resin. The resin must be compatible with the specified finish and meet the purity requirements. After the resin has been selected, it is dried to remove any remaining moisture.

The next step is to prepare the mold. The mold must be cleansed and sterilized to avoid contamination. The injection machine is loaded with resin once the mold has been prepared.

The injection mechanism is then sealed and cleaned with nitrogen gas. This removes oxygen from the machine, which could otherwise cause flaws in the finished product. The nitrogen also aids in keeping the molten plastic at a consistent temperature.


Polyvinyl chloride, more often known as PVC, is a form of flexible plastic with a wide range of applications. Some examples of its use include plumbing pipes and medical equipment. PVC is an excellent material for clean room injection molding not only because it is inexpensive and simple to produce but also because it is resistant to various chemicals.

Polyvinyl chloride (PVC) is produced through the polymerization of vinyl chloride monomers. The finished plastic has excellent durability, high hardness, and dimensional consistency. Because it can be molded into various shapes and sizes, it is an excellent material for use in clean room injection molding.

PVC’s resistance to acids, bases, and salts is all part of its impressive chemical arsenal. Because of this, it is an excellent choice for use in clean rooms, which require a very high level of sterility and sanitation. Due to the fact that PVC does not burn, it can be utilized when working with combustible materials like explosives.

It may be molded into incredibly detailed and intricate shapes thanks to the material’s malleability. As a consequence of this, it is an excellent choice for applications of clean room injection molding that require accurate dimensions.

PVC is an adaptable plastic that may be utilized in many different contexts due to its wide range of properties. It is resistant to a large variety of chemicals, in addition to being affordable and simple to deal with. Due to these qualities, PVC is a good material for injection molding in sterile conditions. In addition, this is available in medical plastic manufacturer.

Furthermore, clean room moldings serve in the maintenance of a sanitary environment and the mobility of staff and equipment inside the space.

What are the benefits of clean room injection molding?

Injection molding in a clean environment provides several advantages, including improved product quality, reduced contamination risk, and increased efficiency.

Injection molding in a clean room environment can help to improve overall product quality by reducing the risk of contamination from dust or other particles.

Contamination risk reduced: By keeping the injection molding environment clean, consumer can help to reduce the possibility that the final product will be contaminated.

Because there is less need for effective cleaning between batches, injection molding in a clean room can also help to improve overall operational efficiency.

What are the drawbacks of clean room injection molding?

There are several potential drawbacks to clean room injection molding, including:

  • High Initial Cost

Multiple design and modeling iterations are frequently required prior to approval or manufacture. After that, the injection molding tool needed to generate the molds must be created and constructed. The mold tool is a sophisticated piece of work that involves people, resources, and many hours of machining to manufacture, and it is the most expensive part of the injection molding process. Obviously, once everything is finished, the part cost is relatively low, and the repeatability for tens of thousands of mouldings is very high.

  • Initial lead time

It could take months from product conception to finished component, design, testing, and tool manufacture. If consumer knows exactly what they want, however, the finished mouldings can be provided in four weeks. Moreover, once the tool is built, running the molds takes relatively little time, especially if the tool has numerous impressions.

  • Large Part Size Limitations

Massive machines are required for plastic injection molding. Depending on the product, a technique such as Plastic Fabrication may be better for the manufacturing of extensive parts, which involves the use of a huge mold tool and is expensive.

  • Careful design needs

Undercuts which drastically increase tooling costs, locked-in features, and insufficient draft. The material and temperature must be considered when designing the walls, or else the mold may not fill entirely. To get an aesthetically pleasing effect, the positioning of ejectors and cooling lines must be researched.

What are the guidelines for clean room injection molding?

There are a few key considerations while designing and constructing clean room injection molded parts. Clean room injection molding tools and work areas must be created and configured to restrict the amount of airborne particles. The molding technique must be adjusted to generate low levels of particle matter. All tools must be stored in a clean, cool environment, and newly purchased instruments must be put through their paces to avoid improper torque or tool usage problems.

What are the best practices for clean room injection molding?

Clean room injection molding (CRIM) is a method of producing things in a clean room. General cleaning, paint removal, interior scrubbing, and operability testing are the four basic cleaning processes used by CRIM.

General cleaning necessitates the disassembly and reassembly of all components that must be cleaned. This can be done with a professional cleaning solution or common household wipes.

Paint removal entails removing any colors or adhesives placed on the molds. This step must be followed before using a mold designed to be reusable.

Cleaning all surfaces within a clean room is what interior scrubbing includes. This can be achieved with either a professional solution or a water-and-soap mixture.

The final phase of CRIM is testing a product’s operability, ensuring that all parts fit well and that the product can be easily made. Inspecting the molds, production processes, and tools can help with this.

The level of air cleanliness is measured according to the ISO 14644-1 standard. ISO specifies a process and technology for medical device injection molding that ensures product quality and safety. This is determined by the usage of limit values. In addition, The ISO 14644 Standard covers the rules and regulations required to manufacture medical devices. This standard establishes a secure and stable infrastructure for medical device manufacturers who strive to develop high-quality products. 

The particle concentration per cubic meter is the determining factor in the ISO classification. The purest level is ISO 1, the least pure level is ISO 9; the highest purity class is ISO 1. This cleanroom class standard is typically implemented in cleanroom systems utilized in the production of semiconductors.

Injection molds for medical devices are covered by this ISO standard for design, manufacture, and testing. Manufacturers of medical devices must adhere to a well outlined process to maintain a high level of quality and safety in their products. This standard creates an all-encompassing structure for designing, developing, and producing injection molds used for medical devices.
