FAQ

Detailed explanation of the production process of medical plastic products

The production of medical plastic products needs to meet special requirements such as high cleanliness, biocompatibility, and sterilization resistance. The core process includes material selection, molding processing, post-treatment, and sterilization. The following are the main production processes and technical points:

1. Material selection and pretreatment

Medical plastics must comply with regulatory requirements such as ISO 10993 (biocompatibility standard) and USP Class VI (United States Pharmacopeia). Common materials include:

• Polypropylene (PP): syringes, infusion bottles

• Polyvinyl chloride (PVC): infusion tubing (requires the use of non-toxic plasticizers)

• Polycarbonate (PC): Transparent surgical instruments

• Polyurethane (PU): Artificial blood vessels, catheters

• Degradable plastics (PLA/PGA): sutures, absorbable scaffolds

Pre treatment process:

• Drying: Some materials (such as PET, PC) need to be dried to remove moisture and avoid the formation of bubbles during molding.

• Blending modification: adding stabilizers, antibacterial agents, etc. to enhance performance.

2. Molding process

According to the shape and purpose of the product, medical plastic products mainly use the following molding techniques:

(1) Injection Molding

• Applicable products: syringes, test tube plugs, surgical instrument handles

Key points of the process:

• High precision molds ensure dimensional stability (such as micrometer level tolerances for syringes).

• Cleanroom (ISO level 8 or higher) to prevent contamination.

(2) Extrusion molding

• Applicable products: infusion tubes, catheters, medical films

Key points of the process:

• Using medical grade screws and barrels to avoid heavy metal precipitation.

• Online detection of thickness and surface defects (such as laser calipers).

(3) Blow Molding

• Applicable products: medicine bottles, eye drops bottles

Key points of the process:

• Multi layer co extrusion technology (such as PP/EVOH/PP) enhances barrier properties and extends the shelf life of drugs.

(4) Thermoforming

• Applicable products: Blister packaging (such as surgical instrument trays)

Key points of the process:

• The material needs to be resistant to ethylene oxide (EO) or radiation sterilization.

(5) 3D printing (Additive Manufacturing)

• Applicable products: Personalized implants (such as skull repair patches), surgical guides

• Materials: PEEK, TPU, UV curable resin (requires biocompatibility certification).

3. Special Process Cases

(1) Multi layer co extrusion of conduits

• Structure: Inner layer (lubricating PU)+middle layer (reinforced nylon)+outer layer (wear-resistant PE).

• Process: Precision extrusion+laser drilling (such as dialysis catheter side holes).

(2) Laser cutting of biodegradable scaffolds

• Material: Polylactic acid (PLA) or magnesium alloy.

• Process: Laser precision cutting followed by electrolytic polishing to avoid scratching blood vessels.

5. Industry Trends and Challenges

Trend:

• Green materials: bio based plastics (such as sugarcane PE) replace petroleum based products.

• Intelligent production: AI quality inspection reduces defect rates.

Challenge:

• Sterilization compatibility (such as the impact of irradiation on material properties).

• Recycling difficulties (plastics contaminated with medical waste require special treatment).
