在生产中注塑模具制品表面经常会出现很多的缺陷，如飞边，缺胶，缩水，气温，发白，气泡，料发等等。要这些问题，要知道是什么原因产生。
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.
生产中注塑模具制品表面出现缩水如何？缩水也称为凹陷，缩痕，是指表面不平整，注塑模具制品由内产生浅坑或者是凹窝。注塑模具制品缩水的原因大概分为两大问题。
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.注塑模具问题 有可能是模具的浇口及流道截面积过小，如果是这样就要扩大相应位置的截面积。也有可能是排气不良，针对其问题，可以改善排气系统。再有就是冷却系统设计不合理，冷却不均匀冷却不足，可以改善冷却系统。
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.注塑工艺调机问题。有可能注塑压力太低和注塑速度太慢，可以适当加大注射压力和提高注射速度。或者是保压时间太短，可以适当合理控制保压时间。
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.
总之注塑模具制品表面出现缩水或者是其它什么问题，先要找出它产生的原因，再根据原因找出相应的方法，对症下药。
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.
