Why We Use Clean Room to Make
Sterile Injection Molding

In order to prevent medical devices and disposables free from contaminants, Seaskymedical carries out sterile injection molding and assembly in clean room to ensure bacteria and pollutants do not impact the safety and function of medical moled products.

Keep Hygiene


To avoid affecting product quality and reliability, cleanroom settings reduce daily pollutants and dust particles. This is critical for firms who want to build trust in medical products by ensuring that their standards meet all health and safety requirements.

Prevent Contamination


Our sterile injection molding in clean room prevents contamination by means of the positive pressure as it avoids non-filtered air from flowing back again to the cleanroom via the exhaust terminals, which ensures that air pollutants don’t gather on small components, impacting their ability to function.

Increase the Likelihood of Injection Machine


Airborne contamination is a significant issue in the medical injection industry. The cleanroom system solves this by carefully managing air flow rates and direction, as well as compression, temperature, and humidity levels, hence increasing the machine life span and performance.

High Performance of Clean Room

Seaskymedical Clean room has a high performance for medical injection mold due to its advantages of static control、humidity and air pressure control as well as Latex floor. It gives good cleaning performance and it does not absorb dust easily. Our clean room is designed in such a way that they can be very cost-effective to operate.

Our Medical Clean Room Injection Molding Capabilities

Thanks to clean room injection molding, medical device parts and disposables could pass IQ/OQ/PQ certification. There are some rigorous inspection procedures for medical molded products. You don’t need to worry about their quality and sterilization.

Product Part Validation

With the help of mirror spark machines, high-speed CNC, and three-dimensional precision manufacturing and measuring equipment, dimensions of medical parts from concept to machining to material selection and manufacturing are monitored and validated all the time.

High-Quality Micro Injection Machine

Advanced injection molding machines from Germany and Japan are working in our clean room, ensuring great production efficiency and large-volume repeatability for medical equipment and consumables. No matter how small the medical parts, our micro injection molding is a great option.

Manufacture Class I/Class II/ Class III Medical Devices

Class I and Class II medical devices are frequently manufactured in our cleanrooms. Clean room injection guarantees the hygiene standard for medical devices. Class III devices require more regulatory oversight, thus they are manufactured under the most strict standards.

Rigorous Quality Control & Inspection

Our medical injection moulding cleanroom adheres to the ISO 13485:2016 quality assurance standard. All plastic materials have biocompatibility reports, their color also has medical certification. Finished products go through a rigorous inspection before delivery.

Medical Clean room Packaging

As a competent clean room injection manufacturer, we provide full services and support to our clients. Like other medical device injection molding factory, apart from clean room molding, efficient and secure cleanroom packaging service is also provided to secure the sterilization.

Medical Clean Room Assembly

As a full-service contract manufacturer of clean room injection, our clean room is well-suited to assembling particle-sensitive medical device components due to our strict control of clean room, which could save our customers time and expense.

Our Clean Room Injection Molding Process

The intricacies of cleanroom injection molding have become more complex as the necessity for cleanliness has grown. The regulation of cleanliness levels continues to be a growing concern. Due to the impact of environmental pollution, which contributes to medical component contamination, clean room molding requires a consistent level of management.

medical products design

Plastic medical products design

We provide both medical product development and design services. You can simply provide us with a 3D or a 2D drawing of desired products no matter if it's for human or animal, with the tolerance requirements, and our team will design them by using various software like SolidWorks, AutoCad, Mold Flow MPI and enhance it for manufacturability.

Plastic Mold Design

Plastic Mold Design

Our injection mold designers have more than 10 years of experience in designing and manufacturing medical pieces and precise molds. materials, cooling systems, ejection mechanisms and other factors are considered when we put forward a perfect mold tool design. Wall thickness is modified to perfection as well.

Material Selection

Injection mold material selection has an influence on the tolerance, dimension, strength, and cost of medical injection molded items. Material color is also certificated. We collaborate with certified color masterbatch suppliers to ensure that you get the best medical-grade material at the best pricing.

CNC Machining

CNC machining

CNC plastic machining uses computer instructions to produce parts or molds. Our mirror spark machine, a high-speed CNC, and three-dimensional precision production technology enable us to manufacture molded products within a relatively short time.
