Perfect Solution for Micro Moulds and Plastics

Overmolding, an injection molding process of coating equipment with several materials, has circulated all manufacturing industries, especially the medical industry. This process is highly favored in the production of medical plastic products as it enhances better grip and ergonomics of devices, creates a waterproof seal, improves resistance to abrasion, dampens noise and vibration, provides electrical insulation, and many other benefits.


At SeaskyMedical, we overmold any kind of plastic medical device to improve the design, functionality and ease of operation. Following the stringent requirements for product cleanliness in the medical industry, we utilize our class 100,000 cleanroom in manufacturing and carrying out overmolding processes.

Molding Benefits from Our German & Japanese Micro Molding Machines

SeaskyMedical is a proficient micro molder with vast experience in molding various micro parts. The benefits you will gain from having us handle your micro molding projects are endless. Here are some of them.

Production of multiple small parts

We’re able to manufacture thousands, millions, even billions of micro parts, ensuring that they have the same dimension and structure. It’s guaranteed that all your micro injected parts will be accurate and the cost will be lower.

Tight tolerance and high precision

We are experts in molding micro parts that hold tight tolerance, even as small as ±5 microns (0.0002 in.). Using our advanced German and Japanese micro molding machines, the shapes, cavities, and designs of the micro parts we mold are produced according to plan, without any deform.

Various micro injection molding capabilities

We have numerous capabilities including manufacturing of thin-wall products, high-temperature, micro insert molding, and micro overmolding. We practice clean room molding to ensure that our medical micro parts are suitable for use inside and outside the body.

Smart control system

With the help of German and Japanese micro injection machines, we have an efficient control system that ensures that the micro molding process is appropriately done. This eliminates any fault or mistake that could rise up.

Contaminant resistance

Our manufactured micro parts are prevented from contamination. The injection molding, packaging, and assembly are all done in the class 7 & 8 cleanroom, thereby preventing any contaminant.

Flexibility assurance

Molds used in micro molding are made of soft materials like aluminum, which allows changes to be made to the design easily. We can help you change your design anytime you want.

Custom Micro Injection Molding Process

At SeaskyMedical, we make flawless micro injection molds that comply with your requirements. Described below are a few out of the many reasons why you should choose us as your micro injection molding company.

Choose materials for micro molding

The following are two of the materials for your custom micro injection molding process. All materials for your custom medical micro injection are available in Seaskemedical.

Silicone micro molding: One suitable material used for micro molding is silicone, which is also known as rubber. It’s an elastic and flexible material that can be conformed to the shape and pattern you prefer.

Micro plastic injection: The other suitable material for custom micro medicine products is plastic. You can use it to make a plastic medical device. There are majorly two types of plastics you can use – thermoplastics and thermosets. The former is recyclable, while the latter is not recyclable.

 Confirm the right injection mold

You need to be certain about the micro injection mold you want. Below are the micro injection molding you can choose from.

Micro insert molding: This is the process of molding plastic or silicone materials around micro parts. The micro parts are inserted into the mold and they are then coated with heated plastic or silicone materials.

Micro overmolding: This is the process of molding another polymer over an already molded micro part. It makes the micro part stronger, easy to grip, and resistant to abrasion.

Choose injection environment

Cleanroom injection environment: This is the process of carrying out the molding process in a specialized cleanroom as approved by the International Organizational Standardization (ISO). This guarantees that the medical products are safe and sterile for use.
