Detailed Introduction

This medical multi-cavity injection mold is tailor-made for complete clinical respiratory atomization and minimally invasive interventional therapy plastic consumables, fully optimized for medical certified POM+PA alloy to meet cleanroom biocompatibility standards and eliminate typical defects such as transparent part flow lines, haze, thin-wall warpage and sealing edge flash.

The split fixed-moving two-plate mold adopts modular symmetrical multi-row cavity layout to realize mass production of all components displayed in the picture: graduated measuring forceps, atomizer main cylinder, transparent liquid storage barrel, curved mask fixing clips, multi-spec three-way flow connectors, multi-size sealing rings, micro one-way valve spuds, filter housing, infusion auxiliary syringes and soft gas delivery hoses. Each miniature component cavity is an independent embedded insert for quick disassembly, replacement and deep sanitization cleaning. All molding contact surfaces undergo multi-stage medical mirror polishing to remove internal fluid dead corners and surface fogging, eliminating secondary post-molding deburring and polishing procedures.

Independent distributed cooling pipelines are arranged for every single cavity to stabilize mold temperature during continuous POM+PA injection molding, effectively restraining differential shrinkage, slender valve rod bending and thin transparent shell deformation. Built-in precision interlock slide locking blocks maintain stable clamping force during long-term cleanroom mass production, preventing flash on tiny thread, micro connector and thin sealing ring structures, and extending 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 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 pass full 3D coordinate measuring inspection to satisfy strict respiratory and interventional medical device drawing tolerance standards. Full customization is supported based on 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, biosafety cleanroom standards and daily production capacity. The modular multi-cavity layout greatly improves molding efficiency while unifying sealing precision, optical transparency and dimensional consistency of full-set disposable respiratory & interventional therapy medical consumables.
