What are the main appearance quality problems of high transparent silicone products?

Transparent products are a category with a large demand in the rubber and plastic industry. In our life, we can see that many plastics and soft hose materials are made of transparent or semi transparent materials, and silicone rubber materials also occupy one of them. There are many kinds of transparent silicone rubber products in the silicone rubber industry. Have you heard about its production?

At present, in many medical and environmental protection and safety fields, they prefer to be clear and transparent. They have no doubt about the quality of the materials of the products. Their functions can be seen at a glance from the appearance and inside of the products. Seeing and feeling is the most important requirement for consumers at present. Therefore, in the silicone product industry, transparent materials used in the field of medical and environmental protection are valued by many people, Although it seems that it belongs to the transparent type, there are certain differences in the production process.

For the manufacturers of high transparent solid silicone products, the production difficulty may be more difficult than that of PC, PE and acrylic materials, because plastic materials are all obtained by liquid solution precipitation and extrusion, and some silicone products need several different processes to produce and process, and are formed by high-temperature molding and curing, so some quality problems in processing are difficult to control.

Although the common problem is that the internal bubbles still exist, there is a certain difference between the fully sealed thermoplastic material processing process and the fully open processing process (silicone material).

Many manufacturers of silicone rubber products know that products with high brightness need great requirements in appearance, so the appearance of the product surface needs to be clean and tidy, comfortable to the touch, and balanced in color. The same or even higher requirements are also applicable to transparent products. In the production process, strict requirements are required for the environmental hygiene of both rubber mixing and molding, Since no color glue is added to the transparent color during mixing, the impurities in the rubber can be seen at a glance. After molding and vulcanization, although there are no black spots on the appearance, there are some other substances in the center of the product that can be seen by every consumer at a glance. Therefore, many manufacturers often have slightly higher defect rates for transparent color products than others.

However, the most important thing is that all kinds of adverse factors caused in the vulcanization production process account for the majority. Because silicone rubber products have different structures, different methods of placing materials and picking up goods during the production operation can lead to defects in different factors. Therefore, correct operation methods can ensure the normal molding of the products. For high transparent products, the most fatal defect is black spots and dirt, Therefore, we also need to strictly control the machine and the surrounding environment.

For the silicone rubber product manufacturers, these factors are the main causes of the bad nature. The biggest cause of the bad nature of the high transparent silicone rubber products can be determined as dirt and impurities, followed by the internal lack of materials and bulging. Therefore, the main reason for the difficulty in production is the internal control!
