Scratching of Injection molding precision parts during the demoulding process is a problem that requires close attention because it is directly related to the quality of the parts and the performance of the final product. In order to avoid this situation from happening, a series of effective measures need to be taken.
First of all, mold design is a key link to avoid scratches. At the beginning of the design, the draft angle of the part needs to be considered. A reasonable demoulding slope can not only ensure smooth demoulding of parts, but also avoid excessive friction during the demoulding process, thereby reducing the risk of scratches. In addition, the structural design of the mold also needs to fully consider the molding and demoulding process of the parts to avoid scratches caused by unreasonable structures.
Secondly, selecting appropriate injection molding materials is also an important measure to avoid scratches. The hardness and scratch resistance of the material have a great impact on the scratch problem of injection molded products. Softer materials are easily scratched, so for injection molding precision parts that require better surface quality, injection molding materials with relatively higher hardness should be selected. At the same time, materials with better wear resistance can also effectively reduce the occurrence of scratches.
In addition, during the injection molding process, strict control of process parameters is also the key to avoiding scratches. Process parameters such as temperature, pressure and time need to be precisely controlled to ensure the stability of the injection molding process and the accuracy of the parts. Excessive temperature or pressure may cause parts to deform or be damaged during demolding, while excessive injection time may increase friction between the part and the mold, increasing the risk of scratches.
Finally, the skill and experience of the operator also play an important role in avoiding scratches. Operators need to be familiar with the operating procedures of injection molding equipment and molds, and operate in strict accordance with process requirements. During the demoulding process, you need to operate gently and smoothly, and avoid using excessive force or improper tools to avoid scratching the parts.
In summary, avoiding scratches on injection molding precision parts during the demoulding process requires comprehensive consideration and implementation from multiple aspects such as mold design, material selection, process control, and operating technology. Only in this way can we ensure that the quality of the parts and the performance of the final product meet the expected goals.
