With the silicone products more and more into our daily life and work, silicone products factory also mushroomed a lot of new manufacturers, which will inevitably have some inferior silicone products into the market. After using some silicone products for a period of time, we will obviously feel that the surface of the silicone product is not smooth enough and there is a sticky feeling, especially on the kitchen utensils and silicone protective covers.

Causes of silicone products surface is not smooth:

(1) Raw material problems, or caused by improper maintenance.

(2) When raw materials are mixed, the control and use of curing agent is unreasonable, and the amount of curing agent added is small, the silicone products are not completely cured, resulting in sticky surface of the products.

(3) The curing agent and silica gel are stirred unevenly when mixing, and the mold presents curing while not curing, resulting in deformation of the product after molding vulcanization due to different hardness and softness.

(4) Finally, the production platform mold cleaning is not clean, the mold closing inside is not smooth enough, the mold contains residual materials, resulting in the product heavy material bump phenomenon, resulting in the product surface is not smooth.

(5) There is no secondary vulcanization, spray handle oil, etc., that is, post-treatment is not enough.

In short, silicone products factory in the production of silicone products, should pay attention to the production of silicone products should pay attention to every detail, not only to avoid the production of silicone products with high defective rate but also reduce unnecessary cost waste, the product has the advantages of addition to static electricity, dust, master sense, sweat corrosion does not fall off, quality assurance, let your customization more worry!

How to avoid silicone products surface is not smooth

With the flow of more and more silicone products on the market, it is inevitable that there are advantages and disadvantages, and some silicone products in use for a period of time, the feeling of the surface is not smooth enough and there is a sticky feeling, especially in the kitchen utensils or silicone mobile phone cover. What causes the surface of silicone products not to be smooth?

What causes the surface of silicone products to be not smooth?

First of all, the control and use of vulcanizing agent when silica gel raw materials are mixed is unreasonable, the amount of vulcanizing agent added is small, and silica gel products are not completely vulcanized, resulting in sticky surface of products. Secondly, the vulcanizing agent and silica gel are stirred unevenly when mixing, and the mold presents vulcanization without vulcanization, resulting in deformation of the product after molding vulcanization due to different hardness and softness. Finally, the production time table mold cleaning is not clean, the inside of the mold is not smooth enough, the mold contains residual materials which lead to the concave and convex phenomenon of the product heavy material, resulting in the product surface is not smooth.

Many friends know that silicone products are widely used in life, and sometimes the products just bought for a period of time lead to the phenomenon that the surface is not smooth enough, especially our kitchen utensils or silicone phone covers, and there will be a sticky feeling, leading to a decline in the use period, and there are many reasons why the surface of silicone rubber products is not smooth enough, which may be caused by improper maintenance. It may be the raw material problem, and what are the reasons for the surface not smooth enough caused by the silicone products manufacturer?

We all know that silicone products manufacturers in the production process is not only a simple rubber chain, molding, quality control to remember how simple processes, for the smoothness of the surface is also a very important requirement, and in addition to raw material problems, silicone products manufacturers lead to the surface of the product is not smooth mainly because of the development of molds, The inside of the mold is not smooth enough to cause the product to have concave and convex phenomenon, and the control and use of vulcanizing agent when the raw material is mixed leads to the deformation of the product after forming vulcanization. Production is the cleaning of the machine and the residual material in the mold that leads to the heavy material of the product, which seems to be caused by two different facial phenomena and so on.

General products will use the oil injection process, general products appear sticky phenomenon after the use of oil injection will not appear sticky hands, currently in the domestic common oil injection process there are two, surface oil injection and laser oil injection. Surface oil spraying is to spray a layer of feel oil on the surface of the product to make the product smooth and feel more comfortable, which is also a simple oil spraying process. Laser oil spraying is to spray the intact silicone products first and then laser to make LOGO, pattern, etc., which is also a very common phenomenon in the current process. There are many kinds of surface treatment processes such as drip glue, color printing, pad printing, etc., are first sprayed in the treatment of oil!
