injection mold parts issue solution
It is a headache to run into the problem of product mucosal in injection mold parts, it not only requires a lot of manpower and material resources to take product out from the mold, but also affected the company’s production efficiency, increasing cost to the company.
But how can we solve the problem of injection mold products mucosa?
At first, we should find out the reason of mucosal. As follows:
1.Bad polishing , for example, it is stick before the mold, May be because after the die polishing better than the previous die polishing Die tryout mold in the production process directly stick in the former mould.
2. Draw taper design may be unreasonable. In theory, front mould draw taper is larger than rear mould draw taper. Putting the draw taper in wrong side may also result to product sticking in the former mould.
5. Mold temperature is too low at the beginning, the product hold too much power to the product.
So we have understanding the reason of mucosal in the test mould, our suggestion of the problem as follows:
1,We must pay more attention to the front mould, the front mould’s polishing should be better than rear mould.
2, For the box, shell and other products, if there is vacuum in front mould, we should use exhaust pin to eliminate the influence of vacuum, but sometimes rear mould need exhaust pin too.
3, If product structure asking for the mould the temperature, we should increase the temperature when testing mould.
4, We can set reasonable injection parameter according to the characteristic of the plastic raw materials, then reducing the possibility of plastic product’ mould sticking.
