硅胶手板模型快速制作是手板模型加工的方式之一，它之所以跟其它手板不一样就是因为加工周期短，加工数量也比较多以及成本低。别的加工方式要做上百个手板的话，不仅加工周期长，而且加工费用也相当昂贵。通常采用CNC加工需要几百元的手板，采用硅胶覆膜的方式来做，只需几十元就可以了。那么硅胶手板在加工的过程中，会碰到什么问题？

Rapid production of silicone mold prototype is one of the ways of prototype processing. The reason why it is different from other prototype is that the processing cycle is short, the amount of processing is relatively large and the cost is low. Other processing methods to do hundreds of hand, not only long processing cycle, and processing costs are quite expensive. Usually CNC processing requires several hundred yuan of hand plate, using silicone coated way to do, only a few dozen yuan can be. So in the process of processing, what problems will be encountered?

硅胶手板模型在加工过程中，经常会遇到的问题就是出现气泡和缩水，硅胶模具在成型温度过高时，在合模加压的过程中表面的硅胶原料已经开始成型，此时的空气已经被困在里面很难排出，所以会造成成型气泡。针对此原因，只需将成型温度适当降低即可。

During the processing of silicone mold prototype, bubbles and shrinkage often occur. When the molding temperature of silica gel mold is too high, the surface silica gel material has begun to take shape in the process of mold closing and pressure. At this time, the air is trapped inside and difficult to discharge, so forming bubbles will occur. For this reason, just reduce the molding temperature appropriately.

而缩水主要是由于热胀冷缩的影响，硅胶在成型的过程中，由于刚开始注入模具里面的是液体，而且温度很高，然而等到硅胶液体冷却后，就会出现体积缩小的情况。因此硅胶手板模型想要跟图纸上面的大小一致的话，在开模具的时候需要稍微开大一点点。

Shrinkage is mainly due to the impact of thermal expansion and cold contraction. In the process of molding, silica gel is injected into the mold with a high temperature. However, when the silica gel liquid cools, the volume will shrink. Therefore, if the silica gel hand plate model wants to be the same size as the drawing, it needs to be slightly larger when opening the mold.

所以硅胶手板模型在加工的过程中，会碰到出现气泡和缩水的情况，希望能对您有所帮助。

Therefore, in the process of processing, the silica gel hand plate model will encounter the situation of bubbles and shrinkage. I hope it can be helpful to you.
