Processing Steps of Medical Plastic Injection Molds

Medical plastic injection molds are core tools for producing plastic products that meet the high standards of the medical industry. They must balance high precision, biocompatibility, and clean production requirements. The following details the processing steps:

1. Core Component Machining

Cavity Machining: Utilizing an ultra-precision grinding machine, positioning accuracy is ±0.0005mm, and parting surface flatness is ≤0.002mm/m.

Microstructure Machining: The hollow cavities of cardiovascular stent molds are machined using slow wire EDM, achieving a surface roughness Ra value of 0.08um and a machining accuracy of ±0.001mm.

Coaxiality Calibration: The coaxiality of the guide posts and guide sleeves is calibrated using a laser interferometer, with the error controlled within 0.001mm.

2. Clean Production Environment

Class 10,000 Cleanroom: The concentration of dust particles ≥0.5um ≤352,000 particles/m within the room prevents impurities from adhering to the mold surface.

Personnel and equipment control: Operators wear hooded sterile gowns, masks, and gloves, and enter the workshop after passing through an air shower to remove dust; equipment is regularly sterilized with ozone or hydrogen peroxide.

Qingdao Xueyu Molding Products Co., Ltd. is mainly engaged in the design and manufacturing of injection molds, injection molding and secondary processing (spraying, pad printing, ultrasonic welding, stamping), etc. For more information about medical plastic injection mold, please contact us.
