硅膠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樣就是因為加工周期短，加工數(shù)量也比較多以及成本低。別的加工方式要做上百個手板的話，不僅加工周期長，而且加工費用也相當(dāng)昂貴。通常采用CNC加工需要幾百元的手板，采用硅膠覆膜的方式來做，只需幾十元就可以了。那么硅膠手板在加工的過程中，會碰到什么問題？

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?

硅膠手板模型在加工過程中，經(jīng)常會遇到的問題就是出現(xiàn)氣泡和縮水，硅膠模具在成型溫度過高時，在合模加壓的過程中表面的硅膠原料已經(jīng)開始成型，此時的空氣已經(jīng)被困在里面很難排出，所以會造成成型氣泡。針對此原因，只需將成型溫度適當(dāng)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.

而縮水主要是由于熱脹冷縮的影響，硅膠在成型的過程中，由于剛開始注入模具里面的是液體，而且溫度很高，然而等到硅膠液體冷卻后，就會出現(xiàn)體積縮小的情況。因此硅膠手板模型想要跟圖紙上面的大小一致的話，在開模具的時候需要稍微開大一點點。

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.

所以硅膠手板模型在加工的過程中，會碰到出現(xiàn)氣泡和縮水的情況，希望能對您有所幫助。

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.
