Is the surface of the silicone mobile phone case reflective normal? What is the reason for the reflective light?
Silicone Protective SleeveIt is very important for the surface of the appearance, so the requirements for black spots, impurities and burr parting lines are very strict. However, there will always be a problem when many silicone products are customized. The appearance of the product is shiny, resulting in uneven face, which seriously affects the appearance effect. For this kind of imagination, anyone will basically think that this is a defective product, so the product has shiny surface, how to deal with this problem?
For the emergence of product shiny, after silicone products manufacturers concluded that there are different reasons, and different reasons can be treated in different ways! The first is the problem of raw materials. The proportion of silicone oil in raw materials exceeds the proportion, resulting in a large area of color difference when forming oil pressure. However, this phenomenon does not occur in general, and precipitation will gradually highlight after time. Therefore, raw materials can be tested well. On the other hand, it is caused by sticking adhesive paper during the process of mixing and cutting. Generally, it is easy to mix adhesive paper into raw materials when cutting raw materials, as a result, the mixed gummed paper is vulcanized at high temperature on the machine table, melted and stuck to the inside and surface of the product when heated. Plastic paper is different from silica gel raw materials, and silica gel does not fuse with any substance, so the shiny thing on the surface of the product is probably plastic paper, which leads to a high probability of the surface of the product!
In addition, it also has a great impact on the surface of the mold in the production process of the machine. If the water on the mold does not dry and the oil pressure starts directly for some long-term products, this phenomenon will lead to the appearance of the product is shiny. When there are black spots and dirt on the surface of the mold, the black spots on the mold are removed with something but some marks are left without treatment, which will also lead to the phenomenon of shiny, the appearance of bright and bright spots after spraying too much release agent is also inevitable. In addition to the silicone protective sleeve, many products appear shiny appearance factors are derived from the above points, and the above problems can be solved through the internal control of silicone rubber products manufacturers, so want a perfect product without defective products, for the choice of silicone suppliers is a very important choice!

Silicone mobile phone caseThe production process
The appearance LOGO of products is made in different ways, and different appearance making processes will have different effects, and the appearance methods of different materials will be different. For example, the hardware of Dongguan Silicone Products Factory can be made by painting and laser, and the plastic products can be made by laser carving, UV spraying, etc. The performance of different materials does not need different methods, and silicone products in the process of processing also useful different appearance LOGO and pattern operation method, generally can use silk screen, transfer, drop glue, color printing, mold printing and other processes, but the most common several methods or can be popular for everyone!
Silicone screen printing is a common process in many industries at present. It is often used as a way of product LOGO and appearance pattern letters. It mainly uses screen printing. Silicone ink is used to integrate the pattern production on the surface of the screen into the appearance of the product surface. Most of the pictures and methods corresponding to the screen are used on some silicone decorations a little more, and there is no three-dimensional effect, but the color is more complex processing effect is not very good!
There are different ways to make the mold printing process. It does not need to have such complicated silk screen effect. It only reflects on the mold, such as silicone LOGO, the double color K of silicone toys. One is that the monochrome LOGO is molded into the finished product at one time, and the surface of the product will show concave and convex phenomenon with stereoscopic impression. However, the lack is only monochrome, and the other is double color K, which is molded into two in one, when another color K is put into the mold, it is formed here. The effect is the same as that of two colors.
The process of glue dripping products is more complicated. It is mainly used for making the appearance of small product decorations, and the output efficiency is relatively low. The only advantage is that it can make many colors and the effect is relatively good. The effect of cartoon 3D effect is that due to the complicated glue dripping process, the mold is small, and manual upper and lower molds are required, so the general products are at most 200*200 template size, mass production is relatively slow and the cost is relatively high. The transfer printing effect is different. It is similar to printing but can do hundreds of thousands of colors. There is no effect that cannot be achieved. The surface of the product can be achieved without unevenness. Transfer printing can be divided into thermal transfer printing, water transfer printing and pad printing. Different methods correspond to different materials and product effects. The advantage is that patterns with any effect can be made. The disadvantage is that the process is troublesome and the cost is relatively high!
Sometimes many friends often encounter different appearance effect problems in product design and do not know how to choose to make them. Therefore, only after understanding the process and appearance can the effect be achieved correctly. Different products need different methods. First, know the manufacturing process and don't choose the wrong method to cause unnecessary trouble!
