Temperature requirements for injection molded pc products
First of all, PC material features high definition, good fracture toughness, stress relaxation resistance, and wide application temperature range. The process characteristics of PC are: melting viscosity requires small cutting rate, but high temperature requirements, no significant melting point, melting The body viscosity is high, and the pc material is easy to react with hydrolysis at high temperature, and the injection molded pc product will be easy to crack.
Injection molding PC products need to carry out sufficient dryness solution before forming production and processing, so that the moisture content is controlled below 0.02. In addition, thermal insulation measures should be adopted for the PC materials during the production process to prevent re-absorption of moisture.
And not only should there be a design plan for injection molded pc products, but also the forming process should be properly grasped, such as increasing the temperature of the abrasive tool, and carrying out post-treatment processes for the injection molded pc products to reduce or clear the heat stress. Immediately adjust the main parameters of the process according to the different conditions of the product.
