Silicone Appearance Pattern Making, Process Details, Do You Know?
Many times, silicone products add some surface appearance treatments, which often bring more selling opportunities, such as adding different color LOGO patterns and three-dimensional effect patterns on the products, etc., and most of these processing methods are known, silk screen, two-color Molding and dispensing, etc., and the appearance of the product is very small, how do you know about the surface of the silicone product?
The purpose of silica gel is to increase the appearance of the silicone product. It is a more diversified side of the product. For example, the surface of the product needs multiple zigzag shapes and the shape of the bite and more shapes can be achieved through the tanning process. It also belongs to a common surface treatment process. The main process can achieve the effect that can be achieved directly on the mold. The mold drying pattern is also called mold biting, mold etching and mold etching because of the process cost. Low, efficient, fast and widely used.
In addition, it can also achieve other effects of the product, such as matte surface, pattern LGLO font and texture, etc. Its main principle is chemical reaction from chemical surface water such as strong alkali sulfuric acid nitric acid, and the silicone mold manufacturer needs to control this. The degree of compounding reaction can be operated to achieve different effects, and its use can also prevent the shrinkage rate of the mold and the defects of the mold clamping line, and the silicone rubber product can appropriately increase the surface strength of the silicone member in the mold after the drying.
For the tanning process of silicone products, the processing difficulty is too large in the design structure of the product and the steel surface of the mold, such as the surface area of the silica gel product, the process route is relatively long, the area is relatively large, and the complicated texture is difficult. Realize, in addition, the mold steel has sand holes, and the material inclination is not enough, which will lead to high and low inequalities in the processed products.
