# Injection foreman # How to adjust the stress mark of PC transparent thimble

It's caused by the mold problem. For more serious cases, analyze the causes and find solutions, as follows: 1, the force is unbalanced, change the position of thimble or add thimble beside it. 2, the mold slope is not enough, so the demoulding slope should be increased. 3. If the polishing is not enough, save the mold on the marked side.

In the case of slight imprint, you can adjust the machine: at 1, don't hit the product to Taibao.2, and raise the mold temperature appropriately. 3. Improve the injection speed and reduce the injection time. 4. Spray the release agent correctly. From work q user: Mr. L.

For pc material, the mold temperature must be between 100 and 150 degrees, and the specific degree depends on the actual problem of adjusting the product. Because the mold temperature is too high, it is beneficial to pc degumming, easy to adjust the product, reduce the pressure speed of glue injection, and also help to improve the top mark. If the mold temperature is too high, top marks will appear. Therefore, it is necessary to effectively reduce the injection pressure, and do not adjust the quick cutting position too full.
