In the injection molding production process, the emergence of burrs is a common problem. It will directly affect the quality of the product, so the injection molding process master needs to find the problem in time and give a solution.

First of all, we need to pay attention to controlling the injection pressure during the injection molding process. Excessive injection pressure can easily lead to excessive flow of material in the mold, resulting in burrs. Therefore, we should reasonably adjust the injection pressure to avoid excessive pressure adversely affecting product quality.

Secondly, improving the clamping force is also the key to solve the burr problem. Insufficient clamping force will cause the mold to shift and shake during the injection molding process, which will cause burrs on the surface of the product. By increasing the clamping force, the displacement of the mold can be effectively reduced, thereby reducing the generation of burrs.

In addition, adjusting the injection volume and dropping temperature is also an effective way to solve the burr problem. Excessive injection volume will cause the material to flow unevenly during the injection molding process, resulting in burrs. By appropriately reducing the amount of injection, the material can fill the mold more evenly, thereby reducing the generation of burrs. At the same time, the appropriate reduction of temperature can also reduce the fluidity of the material and reduce the occurrence of burrs.

In short, the appearance of burrs has a direct impact on the quality of injection products. The injection molding process master needs to make reasonable adjustments to the injection pressure, clamping force, injection volume and temperature in the injection molding process to solve the burr problem and ensure the stability and reliability of product quality.
