Packson Medical Plastic Injection Molding Capabilities

Class 8 Level Cleanroom
Class 8 Level Cleanroom

11 Medical Molding Machines and 3-Axis Robots

We have two separate, state-of-the-art facilities that boast more than 1,000 square meter of combined cleanroom infrastructure. At our facility, we have a stand-alone cleanroom equipped with 11 medical molding machines ranging from 60T to 160T. Each machine is situated in its own Class 8 cleanroom and is fitted with a 3-axis robot for efficient automation of the molding process. Our cleanroom environment ensures that your medical components are manufactured in an environment that meets stringent quality standards.

Class 7 Level Cleanroom
Class 7 Level Cleanroom

In an ISO 7 cleanroom, product assembly requires a high level of precision and attention to detail. The controlled environment is designed to minimize the presence of airborne particles and other contaminants that could negatively impact the quality of the finished product. Assembly in an Class 7 cleanroom follows strict protocols to ensure that no contamination occurs during the process. Workers must wear specialized clothing designed to limit the amount of particles they generate, such as gloves, hairnets, face masks, and full-body suits. All tools and equipment used in the cleanroom must be meticulously cleaned and sanitized before use. 


As part of their training in the latest IQ/OQ/PQ mold validation protocols, the experienced Quality Engineering staff has been instructed on various techniques including First Article Inspection, process DOE, Gauge R&R, CpK Analysis, among others.


Our facility maintains ISO 13485 certification and consistently adheres to the internationally recognized quality standard for designing and manufacturing Medical Devices.


Our medical molding machines come equipped with their own multi-axis robotics systems which handle part handling and cavity separation. These systems are integrated with our process monitoring system to eliminate any products that fall outside of our established molding parameters, set during our rigorous mold validation.


Our Process Engineers employ a scientific molding process, and as an additional measure, we routinely implement cavity pressure sensors and process monitoring technology to ensure 100% monitoring and traceability for patient-critical applications.

  • Material Properties



It is also called polythene that can be formulated in high or low densities. It is economic, resistant to impact and corrosion absorbs little water, and retains its overall performance and structural integrity after frequent sterilization cycles. A porous synthetic polymer, polyethylene is biologically inert, does not degrade in the body, and is often used in medical implants.



It is a thermoplastic polymer used in all kinds of applications. Polypropylene is a white material that is mechanically rugged with high chemical resistance. It is commonly applied in disposable syringes, connectors, finger-joint parts, plastic containers, pharmacy bottles, and clear bags.

Polymethyl methacrylate(PMMA)


Poly(methyl methacrylate) is a common material used in modern dentistry. It is a good choice for the parts that require transparency, toughness, hardness, and almost perfect transmission of visible light. It is an ideal material to make a glass effection part.

Liquid Silicone Rubber(LSR)


Liquid silicone rubber is a high-purity, two-component platinum-cured silicone, normally processed through liquid injection molding (LIM). It is widely used in medical catheters, breathing masks, and rubber teats.



Polyamide, also named nylon, is a synthetic thermoplastic polymer that is commonly used for CNC machining, injection molding, and 3D printing. It can be combined with other materials to enhance its overall strength. It is a good choice for parts that see a lot of wear and tear.

Acrylonitrile butadiene styrene (ABS)


ABS has been widely applied in molding production also 3D-print manufacturing for OEMs. It shows the resistance of impact and heat features. It is also hard enough to make it as good engineering plastic. It can be used in injection molding, blow molding, extruding, and so on. Common uses include non-absorbent sutures, tendon implants, drug-delivery systems, and tracheal tubes.



Polycarbonate is also named PC. It shows naturally transparent and provides good UV protection. Polycarbonate is good for use in glass, shock-resistant, and medical grades can be sterilized at 120 °C. Polycarbonate is lightweight, provides chemical-, electrical-, heat- and impact resistance, stability, and high performance.
