Detailed Introduction

This medical multi-cavity injection mold is customized for full-series laboratory and clinical testing transparent plastic consumables, optimized for medical-grade POM+PA alloy to meet laboratory cleanroom biocompatibility standards and eliminate micro flow marks and residual contaminants inside detection chambers.

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: 96-well microplates, sample test tubes, culture petri dishes, pipette tips, fluid flow connectors, surgical speculum housings, liquid storage cylinders and calibration clamping accessories. Each component cavity is an independent embedded insert for rapid disassembly, replacement and deep sanitization cleaning. All molding surfaces go through multi-stage medical mirror polishing to remove micro burrs, internal dead corners and haze, 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 plate warpage and slender pipette tip deformation. Built-in precision slide locking blocks maintain stable clamping force during long-term cleanroom mass production, avoid flash on ultra-fine thin-wall structures, and extend mold service life under cyclic medical plastic processing.

Complete Precision Machining Workflow

1. 5-axis CNC rough milling for mold base outline and large multi-well 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 micro well, thin tube and flow connector 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 complete full 3D coordinate measurement inspection to satisfy strict laboratory testing medical drawing tolerance standards. Full customization is supported based on lab 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 symmetrical multi-cavity layout greatly improves molding efficiency while unifying dimensional accuracy, optical transparency and sealing stability of laboratory clinical testing consumables.
