Key Design Considerations for Medical Injection Molds

Medical injection molds are high-precision, specialized molds used to produce medical consumables and devices. Their design, material selection, and manufacturing processes must meet the stringent standards of the medical industry to ensure the safety, effectiveness, and reliability of the products. The following details the key design considerations:

1. High-Precision Design: Medical products have extremely high requirements for dimensional accuracy and surface quality. Mold design must ensure precise dimensions and a smooth, defect-free surface. For example, syringe piston molds must achieve precise dimensions without eccentricity, and the plastic part must have high light transmittance and be free of dents.

2. Optimized Gating and Venting Systems: Gating design directly affects the aesthetics and performance of the plastic part, and defects such as serpentine flow must be avoided. Simultaneously, a reasonable overflow and venting system must be designed to prevent air bubbles or scorching inside the product.

3. Rational Mold Structure: The mold structure must facilitate processing, assembly, and maintenance, while ensuring the mold's strength and rigidity. For example, using an insert design in the mold structure allows for the interchangeability of identical parts within the mold, improving the mold's versatility and maintenance efficiency.

4. Material shrinkage rate consideration: Plastics shrink during processing. Mold design needs to adjust the mold size according to the shrinkage rate of plastics to ensure product size stability.
