Product Overview
This is a high-output 1*24-cavity custom injection mold specially designed for mass production of LDPE medical protective covers. Targeting the characteristics of thin-wall, lightweight and high hygiene requirements of medical cover parts, the mold adopts high-end S136 stainless steel with HRC48-52 high hardness heat treatment, achieving long service life and anti-corrosion performance suitable for medical clean workshops.
Equipped with a professional pin point horn gate feeding system, the mold realizes balanced and rapid filling of 24 cavities at one time. The unique dual-surface process of mirror polished core + stoned cavity finish enables the finished medical covers to have smooth inner walls (easy cleaning, no residue) and delicate matte outer surfaces (anti-slip, high-grade appearance). All mold structures are optimized for LDPE material flow and shrinkage, ensuring consistent dimensional accuracy, no burrs, no warpage, and 100% qualified appearance for each batch of medical covers. It is the preferred high-efficiency mold solution for disposable medical protective accessories.

Core Technical Advantages
1. S136 High Hardness Stainless Steel, Medical Anti-Corrosion Grade
Different from ordinary mold steel, S136 stainless steel with HRC48-52 high hardness features superior rust resistance and chemical stability. It can effectively resist moisture, disinfectant vapor and long-term cleanroom environment erosion, avoiding mold rust, spots and surface peeling. It maintains stable precision and clean cavity surface during millions of injection cycles, fully meeting medical hygiene production standards.
2. Pin Point Horn Gate for Automated & Flawless Production
The customized horn-type pin-point gate adopts micro-hole feeding design. It realizes automatic gate separation during mold opening without manual trimming, supporting fully automated mass production. The tiny gate residual mark is almost invisible on the product surface. Meanwhile, the horn transitional structure optimizes LDPE melt flow, avoids jetting and material stagnation, and ensures consistent filling balance for all 24 cavities.
3. Dual Surface Craft Meets Medical Dual Standards
The core adopts high-precision mirror polishing, making the inner surface of medical cover ultra-smooth without dead corners, preventing dust and bacteria adhesion, convenient for disinfection and cleaning. The cavity adopts fine stoned finish, creating a uniform matte outer surface that improves texture and scratch resistance. This dual design perfectly balances medical hygiene safety and product appearance quality.
4. 24-Cavity Balanced System for Ultra-High Yield
The mold adopts professional runner balance design for 24 cavities, ensuring consistent injection pressure, flow rate and cooling effect of each cavity. No uneven filling or different product weight occurs. It greatly improves daily output, reduces average labor and machine cost per piece, and creates high profit margins for mass medical part production.
5. Exclusive Optimization for LDPE Thin-Wall Medical Parts
LDPE features high toughness and large shrinkage rate. We optimize cooling channel distribution and venting structure according to LDPE material characteristics, effectively controlling thin-wall warpage, sink marks and dimensional deviation. The produced medical covers have uniform wall thickness, good flexibility and high fitting accuracy, suitable for secondary sterilization and medical assembly.
Applications
