硅胶手板模型是重要的一种手板材料。很多产品中都需要用到硅胶产品。那么硅胶手板模型加工注意事项有那些呢？下面济南手板厂家就来为大家进行介绍。

Silicone prototype is an important prototype material. Silicone products are required in many products. What are the precautions for the processing of silica gel prototype? Now, Jinan Prototype Factory will introduce to you.

1、模具硅胶里有很多气泡

1. There are many bubbles in the silica gel of the mold

这种情况要依据条件来处里，在有抽真空机的条件下，先要把硅胶与固化剂搅拌均匀后进行抽真空处理。如没有真空机则可以适当减少固化剂的添加量来进行处理，比如原硅胶与固化剂的比率为4%,现在可以改成1%-2%。这样前期模具硅胶胶连时间就会变慢，模具中的空气就会慢慢排出，减少气泡。

This situation should be dealt with according to the conditions. If there is a vacuum pump, the silica gel and the curing agent should be stirred evenly before vacuumizing. If there is no vacuum machine, the addition of curing agent can be appropriately reduced for treatment. For example, the ratio of original silica gel to curing agent is 4%, which can now be changed to 1% - 2%. In this way, the silicon gel bonding time of the mold in the early stage will be slow, and the air in the mold will be slowly discharged to reduce bubbles.

2、硅胶出现粘模

2. Silicone adhesive

出现这种情况一是因为前期对模种（产品模型）没有合理处理造成的，所以在开模前要对模种进行处理，如模种表面比较粗燥或做很复杂的模具，一定要认真打磨光滑清洗干净。然后再均匀刷上脱模剂。常用的脱模剂有凡士林、洗洁精、液体石蜡等。实际操作中可根据模种的材质涂刷不同的脱模剂。二是固化剂搅拌不均匀就倒入模具框中，脱模时一块干一块不干。

One reason for this is that the mold (product model) was not properly treated in the early stage, so the mold must be treated before opening the mold. If the surface of the mold is rough and dry or the mold is very complex, it must be carefully polished, smooth and cleaned. Then evenly brush the release agent. Common mold release agents include Vaseline, detergent, liquid paraffin, etc. In actual operation, different release agents can be applied according to the material of the mold. Second, the curing agent will be poured into the mold frame if it is not stirred evenly, and it will be dried one by one during demoulding.

3、硅胶模具产品变形

3. Silicone mold product deformation

这个要依据产品的大小来分开处理，原则上是产品的大小尺寸与所使用硅胶的硬度成正比。若是小件产品或非常精细的产品可以使用很软的硅胶来开模，硬度一般在10-20度，这样会好脱模，还不会破坏精细产品的纹路。

This should be handled separately according to the size of the product. In principle, the size of the product is proportional to the hardness of the silica gel used. For small products or very fine products, very soft silica gel can be used to open the mold. The hardness is generally 10-20 degrees, which will facilitate demoulding and will not damage the grain of fine products.

若是大件产品比如大于50公分的产品就一定要使用硬度为40-50的硅胶来开模。这样才不会变形。

For large products, such as products larger than 50 cm, silicone with a hardness of 40-50 must be used to open the mold. This will not deform.

若是做很大而且又很精细的产品可以使用硬度为30度左右的硅胶来开模（方法是刷一层硅胶蒙上一层玻璃纤维布再刷一层硅胶），外面可以用石膏，玻璃钢（即不饱和树脂+玻璃纤维布）来做外膜，以此来保护的产品不变形。

For large and fine products, silica gel with a hardness of about 30 degrees can be used to open the mold (the method is to brush a layer of silica gel, a layer of glass fiber cloth, and then a layer of silica gel). Plaster and glass fiber reinforced plastic (i.e. unsaturated resin+glass fiber cloth) can be used outside to make the outer film to protect the products from deformation.
