We know that many enterprises will mold the designed new products in the process of product production, so as to achieve the purpose of mass production. However, many enterprise staff will ignore the grinding of copied products, resulting in slight marks on the surface of the mold products, affecting the beauty of the products. In addition, the negligence of the staff will also lead to similar situations, that is, failure to apply the release agent evenly will also lead to defects in the replica products.

硅胶手板除了容易出现瑕疵影响产品美观之外，济南手板工作人员还发现有模具成品会出现不同程度的不耐酸碱、抗老化能力弱等。什么原因导致这种现象呢?很多时候是因为添加过量硅油造成的。

Besides the defects that affect the appearance of the products, the Ji'nan hand board staff also found that the mold products will exhibit different degrees of acid and alkali resistance and weak aging resistance. What causes this phenomenon? It is often caused by adding too much silicone oil.

在模具制造过程中添加过量硅油会导致硅胶分子量受到破坏，影响硅胶性能，降低其抗酸碱能力和抗老化能力。基于这样的现实，我们建议大家在进行硅胶复模时不要添加硅油，要加的话应该将量控制在7%左右。

Adding excessive silicone oil in mold manufacturing process will cause the molecular weight of silica gel to be damaged, affect silica gel properties, reduce its acid and alkali resistance and anti-aging ability. Based on this reality, we suggest that you do not add silicone oil during silica gel re molding. If you want to add silicone oil, you should control the amount to about 7%.

烧模现象也是比较常见的一种。其中我们还发现，硅胶手板在进行树脂类产品复模时复模时间应该控制在一定范围内，不然容易出现烧毁模具的现象。

Mold burning is also a common phenomenon. Among them, we also found that when the silicone hand board is used for resin product re molding, the re molding time should be controlled within a certain range, otherwise it is easy to burn the mold.

在进行树脂产品复模的过程中，常常需要加入一些过氧化物的固化剂来实现模具制造，而这类物质与硅胶接触一段时间之后会发生化学反应产生大量热量，因此不适宜较长时间的制模过程。时间应该控制在什么范围内呢?一般在3分钟以内为佳。

In the process of resin product re molding, it is often necessary to add some peroxide curing agent to realize mold manufacturing, and this kind of material will have a chemical reaction after contacting with silica gel for a period of time and produce a lot of heat, so it is not suitable for a long time of molding process. Within what range should time be controlled? Generally within 3 minutes is better.
