Detailed Introduction

This medical multi-cavity injection mold is tailor-made for complete sets of minimally invasive therapeutic instrument plastic consumables, optimized for medical certified POM+PA alloy to meet cleanroom biocompatibility requirements and eliminate molding residue and micro defects inside fluid passages.

The split fixed-moving two-plate mold adopts symmetrical multi-row cavity layout to boost single-cycle output for all components shown in the picture: main instrument hand grip housing, transparent flow cylinder, elastic corrugated connecting tubes, threaded joints, positioning locking buckles, filter mesh sleeves and sealing rings. Each functional component cavity is an independent embedded insert, supporting quick disassembly, replacement and deep cleaning. All molding contact surfaces undergo multi-stage medical mirror polishing to eliminate micro burrs, flow lines and blind corners, removing post-molding secondary trimming and cleaning procedures.

Independent distributed cooling pipelines are laid out for each cavity to stabilize mold temperature during continuous POM+PA injection molding, effectively suppress differential shrinkage, corrugated tube distortion and warpage of thin transparent shells. Built-in precision slide locking blocks maintain stable clamping force during long-term cleanroom mass production, avoid flash on tiny threads, buckles and thin mesh structures, and extend mold service life under long-cycle medical plastic molding.

Complete Precision Machining Workflow

1. 5-axis CNC rough milling for mold base outline and complex 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 thread, corrugated tube, mesh and thin-wall transparent housing contours
5. Multi-stage medical mirror polishing to achieve high light transmittance, residue-free 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 meet strict minimally invasive medical equipment drawing tolerance standards. Full customization is supported based on instrument 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 dimensional accuracy, sealing stability and surface light transmittance of minimally invasive therapeutic medical consumables.
