Injection molding is a widely employed manufacturing process for producing plastic components, and it is well-suited for the production of medical devices due to its ability to provide high precision, consistency, and scalability. Medical devices require a high level of cleanliness to ensure patient safety. Magnetic platen can help to keep the injection molding machine clean.

Why should injection molding machine be clean?

Cleanliness directly affects the quality of the medical devices being produced. Contaminants such as dust, residues, or impurities can compromise the structural integrity, functionality, or appearance of the devices. Regular cleaning and maintenance of the machine help prevent defects and ensure that each product meets the required quality standards.magnetic clamping system

Clean machines tend to operate more efficiently. When the injection molding machine is free from contamination, it can function optimally, ensuring accurate measurements, consistent melting and molding processes, and lower reject rates. This efficiency improves productivity and reduces manufacturing costs.

How magnetic platen keep injection molding machine clean?

With magnetic mold clamping, there are fewer components and crevices that can accumulate dirt, grease, or other contaminants. The simplicity of the system allows for easier access during cleaning procedures, ensuring thorough cleaning of the machine and the molds.

Traditional mechanical clamps can be prone to corrosion or rusting over time. In contrast, magnetic mold clamping systems are typically made of non-corrosive materials such as stainless steel. This resistance to corrosion reduces the risk of any rust particles or residues contaminating the manufacturing process.clean magnetic platen

Compared to hydraulic clamping systems, magnetic platen has the advantage of not causing leakage. Hydraulic clamping systems rely on hydraulic fluid to apply pressure and hold the mold in place.  The hydraulic fluid is pressurized and circulated throughout the system, which increases the risk of leaks due to damage, wear and tear, or other factors such as temperature changes. Magnetic platen use magnetic force to hold the mold in place, eliminating the need for hydraulic fluid.  

Magnetic platen decreases mold changeover time to 3 minutes

Magnetic mold clamping systems often offer faster mold changeovers. This advantage reduces production downtime and increase efficiency.


Injection molding machines for medical device are complex and costly equipment. Regular cleaning and maintenance help prevent the buildup of residue, corrosion, or mechanical issues that can adversely affect the machine’s performance and lifespan. Proper care and cleanliness can extend the longevity of the equipment, reducing the need for frequent repairs or replacements.
