PEEK is a thermoplastic material, and the mold needs to be heated during injection, which requires the mold to have a corresponding heating temperature measurement system, and the template is required to maintain sufficient strength under high temperature and high pressure. In addition, when injecting fiber-containing PEEK raw materials, the requirements for mold materials will be higher, otherwise the mold life will be shorter.

Pay attention to when peek injection:

1. The uniformity of mold heating distribution;

2. The gate and runner are designed to be half of the thickest wall thickness of ultra-thick parts;

3. The pressure setting during injection molding should be higher than half of the plastic;

4. For parts with high dimensional accuracy requirements, heat treatment should be carried out after injection molding;

5. The mold and molten material have high temperature, so pay attention to safety to prevent burns.

The structural design of PEEK injection mold is similar to that of ordinary molds, but the following conditions need to be considered separately: the material of the mold needs to be able to maintain sufficient strength at high temperatures, the injection gate and runner are larger than normal, and the mold needs to be equipped with corresponding The heating temperature measuring device.
