Detailed Introduction

This medical multi-cavity injection mold is tailor-made for complete series of clinical respiratory therapy plastic consumables, optimized for medical certified POM+PA alloy to meet operating room cleanroom biocompatibility standards and eliminate flow lines, haze and micro burrs on transparent gas circulation parts.

The split fixed-moving two-plate mold adopts symmetrical multi-row cavity layout to boost single-shot production output for all integrated components displayed: atomizer main cylinder, scaled measuring forceps, curved mask fixing clips, multi-spec three-way flow connectors, transparent gas pipelines, sealing rings, one-way valve spuds, limit positioning strips and miniature transfer joints. Each functional component cavity is an independent embedded insert for quick disassembly, replacement and deep sanitization cleaning. All molding surfaces receive multi-stage medical mirror polishing to remove internal fluid dead corners and surface fogging, removing post-molding secondary deburring and polishing procedures.

Independent distributed cooling pipelines are laid out for every cavity to stabilize mold temperature during continuous POM+PA injection molding, effectively restrain differential shrinkage, thin transparent shell warpage and slender valve rod deformation. Built-in precision slide locking blocks maintain stable clamping force under long-term cleanroom mass production, avoid flash on thin sealing edges and tiny micro-joint structures, and extend mold service life under cyclic medical-grade plastic processing.

Complete Precision Machining Workflow

1. 5-axis CNC rough milling for mold base outline and complex multi-feature cavity rough forming
2. Vacuum stress relief heat treatment to stabilize steel hardness and reduce thermal deformation under long-run medical POM+PA molding
3. Precision surface grinding to control mold plate flatness & parallelism within ±0.002mm
4. Sinker EDM & Wire Cut WEDM for ultra-fine slender valve rod, thin sealing ring, curved clip and multi-way connector contours
5. Multi-stage medical mirror polishing to achieve high light transmittance, residue-free transparent cavity surface
6. Optional non-toxic anti-corrosion surface coating compatible with medical POM+PA raw materials

All mold core, cavity and structural components complete full 3D coordinate measurement inspection to satisfy strict respiratory medical device drawing tolerance standards. Full customization is supported based on respiratory therapy consumable samples or engineering drawings: cavity quantity, mold steel grade, cooling circuit layout and polishing grade can be adjusted according to POM+PA medical certification grade, cleanroom hygiene standards and daily production capacity. The symmetrical multi-cavity layout greatly improves molding efficiency while unifying sealing precision, light transmittance and dimensional consistency of full-set inhalation therapy disposable consumables.
