During the working process of injection molds, temperature, pressure, and time are key parameters. The appropriate temperature can fully plasticize the plastic while avoiding deformation caused by mold overheating; Appropriate pressure can ensure that the plastic fills the mold cavity, forming a complete product; A reasonable time ensures that the plastic is fully cooled and solidified in the mold to achieve ideal product quality.

Injection molds can be classified based on different molding characteristics and processes. According to the molding characteristics, injection molds can be divided into two types: thermosetting plastic molds and thermoplastic plastic molds. According to the molding process, injection molds can be divided into transfer molds, blow molds, casting molds, hot forming molds, hot pressing molds (compression molds), and injection molds. Among them, injection molds can be divided into two types based on the different pouring systems: cold runner molds and hot runner molds.
