Three Situations That Must Be Noted in the Injection Molding Process

Injection molding tooling holds a significant place in modern manufacturing, serving as a key element in achieving efficient and high-quality production. Injection molding is a field that requires extensive knowledge, technical skills, and practical experience. Throughout the entire injection molding process, various materials and equipment are used, including plastic raw materials, colorants, regrind material, molds, injection molding machines, peripheral equipment, jigs, sprays, various auxiliary materials, and packaging materials. This naturally adds considerable workload and complexity to the management of an injection molding workshop. For this reason, it is essential to pay attention to the following three situations in the injection molding process.

1. Temperature Control for Different Materials
   Each type of raw material requires a specific temperature during injection molding. Deviating from the optimal temperature can lead to poor results. If the temperature is too low, it may affect the color of the liquid material; if it is too high, it can cause flashing. Therefore, the injection molding temperature must be strictly controlled according to the characteristics of the material used.

2. Controlling Injection Speed
   During injection molding, it’s also crucial to control the injection speed. If the speed is too high, it can lead to flashing, overfilling, or even burn marks. On the other hand, if the speed is too low, shrinkage and breakage may occur. Therefore, managing the injection speed is essential to ensure the quality of the final product meets the required standards.
3. Regulating Cooling Time
   In the injection molding process, cooling time control is also important. The precise cooling time depends on the specifics of the product being molded and must be adjusted accordingly.
