medical injection molding high Precision plastic Mould for Medical products

(1) Strict requirements for mold material selection
Most disposable medical device products use medical grade polyvinyl chloride (PVC) and polycarbonate (PC). Because PVC has better corrosion resistance than steel, and PC has higher hardness, there are strict requirements for the selection of mold materials. It is recommended that domestic mold manufacturers choose Swedish-Shengbai S136H or Japanese Datong NAR-80 steel. These two materials have strong corrosion resistance and high polishing performance.

(2) The heat treatment process controls the hardness
Since the medical grade PVC material has good fluidity, the parting surface is deformed due to the soft material of the mold during the use of the mold, which in turn leads to flash burrs during the injection molding process. Therefore, the hardness of this type of mold material is relatively high. The heat treatment process used in the mold manufacturing process is to perform quenching and tempering treatment after rough machining of the template, and the hardness is controlled at HRC32-36; after the mold trial sample is qualified, the hollow mold, the movable mold, and the core are subjected to vacuum quenching and hardness control In HRC58-620

Mold description:
1. Mold material

We use high-strength mold materials for medical mold bases. Available materials include: 2083. P20H, 718H, etc.; the main part of the medical mold, including the core cavity, return plate (banquet) and related weirs, We use Gaoyi's plastic mold steel. The materials that can be made include: 2083, 2314, 2311.2316, 2738, S136, etc.: and professional heat treatment companies heat the main part of the medical mold, and the basic degree of the material is generally more than HRC45;

2. Mold design
Leveraging on Western medical mold design, and combining our rich experience, using innovative mold design, the quality of the medical tool of Yidian Mold can reach perfection;

3. Mold parts processing
We use Gaolian CNC.an tool center to process the molds and carry out standardized operations: to ensure the precise change of each medical mold event, and to achieve the interchangeability of each part:

4. Fast cycle time
Apply perfect cooling water channels to medical molds, combined with the use of fast cooling materials, optimize the ring time, make production faster and more stable, and improve production efficiency;

5. Selection of cavity number of mold
1 cavity: 1x2 cavity: 2x2 cavity: 2x3 cavity: 2x4 cavity: 2x6 cavity: 3x4 cavity: 3x8 cavity: x4 cavity: 4x6 cavity: 4x8 cavity: 6x6 cavity: 6x8 cavity: 6x12 cavity:

6. Hot runner system of mold
The self-developed high-speed natural flow channel system is reliable and stable: it can withstand the high-pressure injection pressure without glue. After optimizing the deep mouth of the mold, a perfect strong material product can be produced: all parts of the hot path of the medical mold are made of high precision, high degree of precision, and super abrasive materials:

7. Mold delivery time
Fast delivery time, the delivery time of medical school equipment is controlled within 60 working days:
