在生產(chǎn)中注塑模具制品表面經(jīng)常會出現(xiàn)很多的缺陷，如飛邊，缺膠，縮水，氣溫，發(fā)白，氣泡，料發(fā)等等。要這些問題，要知道是什么原因產(chǎn)生。
In production, many defects often appear on the surface of injection mold products, such as flash, lack of glue, shrinkage, temperature, whitening, bubbles, material hair and so on. To solve these problems, we must first know what causes them.
生產(chǎn)中注塑模具制品表面出現(xiàn)縮水如何？縮水也稱為凹陷，縮痕，是指表面不平整，注塑模具制品由內(nèi)產(chǎn)生淺坑或者是凹窩。注塑模具制品縮水的原因大概分為兩大問題。
How to solve the shrinkage on the surface of injection mold products in production? Shrinkage, also known as depression and shrinkage mark, refers to the uneven surface and shallow pits or pits produced in the injection mold products. The reasons for the shrinkage of injection mold products can be divided into two major problems.
1.注塑模具問題 有可能是模具的澆口及流道截面積過小，如果是這樣就要擴大相應(yīng)位置的截面積。也有可能是排氣不良，針對其問題，可以改善排氣系統(tǒng)。再有就是冷卻系統(tǒng)設(shè)計不合理，冷卻不均勻冷卻不足，可以改善冷卻系統(tǒng)。
1. The problem of injection mold may be that the cross-sectional area of the gate and runner of the mold is too small. If so, it is necessary to expand the cross-sectional area of the corresponding position. There may also be poor exhaust. Aiming at the problem, the exhaust system can be improved. Another is the unreasonable design of the cooling system, uneven cooling and insufficient cooling, which can improve the cooling system.
2.注塑工藝調(diào)機問題。有可能注塑壓力太低和注塑速度太慢，可以適當加大注射壓力和提高注射速度。或者是保壓時間太短，可以適當合理控制保壓時間。
2. Adjustment of injection molding process. It is possible that the injection pressure is too low and the injection speed is too slow. You can appropriately increase the injection pressure and speed. Or the pressure holding time is too short, so the pressure holding time can be properly and reasonably controlled.
總之注塑模具制品表面出現(xiàn)縮水或者是其它什么問題，先要找出它產(chǎn)生的原因，再根據(jù)原因找出相應(yīng)的方法，對癥下藥。
In short, in case of shrinkage or other problems on the surface of injection mold products, we should first find out the causes, and then find out the corresponding solutions according to the causes.
