Detailed Introduction

This medical multi-cavity injection mold is developed exclusively for transparent medical disposable plastic parts, complying with medical production cleanliness requirements to eliminate mold residue contamination and product surface defects.

The mold consists of fixed mold half and moving mold half, with dual symmetrical multi-row cavity zones to boost single-cycle output. Each miniature medical cavity is independently embedded for separate maintenance and replacement; all molding surfaces are ultra-mirror polished to ensure transparent medical parts have zero flow lines, haze or tiny burrs, eliminating secondary finishing. Built-in precision slide locking blocks guarantee stable mold clamping under long continuous production, and separate cooling pipelines are arranged for every cavity to control uniform mold temperature and prevent transparent medical plastic from internal stress and warpage.

Complete Precision Machining Workflow

1. 5-axis CNC rough milling for mold base overall outline and cavity rough forming
2. Vacuum stress relief heat treatment to stabilize steel hardness and reduce thermal deformation
3. Precision surface grinding to control mold plate flatness and parallelism within ±0.002mm
4. Sinker EDM & wire cut WEDM for delicate miniature medical part contour
5. Medical-level multi-step mirror polishing to achieve high light transmission cavity surface
6. Optional non-toxic anti-corrosion surface treatment compatible with medical PP/PC raw materials

All mold components undergo full 3D coordinate measurement inspection to satisfy strict medical drawing tolerance standards. Custom development is fully supported based on medical part samples or engineering drawings: mold steel grade, cavity quantity, cooling circuit layout and surface finish can be adjusted according to medical plastic material, hygiene grade and daily production volume. The multi-cavity symmetrical layout greatly improves molding efficiency while maintaining consistent quality of transparent medical consumables.
