How to solve the appearance defects of silicone products?

For the manufacturing industry, any product sold to consumers can only be considered reassuring if it can be guaranteed. Therefore, in any industry, the key to ensuring product quality through source production control is to strictly control it. The silicone industry is no exception. Compared to other industries, the quality control of silicone products does not require precise and fine-grained requirements, but depends on whether the appearance and functionality of the product reach the expected level. So, what aspects should be controlled for the quality of silicone products?

In normal solid-state liquid technology and other processes, different products have different requirements. For example, silicone sealing rings and silicone phone cases belong to two different functional roles. One needs to control size and stretching force, and the other needs to control soft hardness and appearance. It is crucial to identify different testing standards for different quality issues.

And poor appearance is the main problem for most silicone products. Currently, many Dongguan silicone product manufacturers have certain defects in the surface control of high-end products, with many black spots and impurities exceeding industry standards and specifications. Therefore, many silicone manufacturers classify some products with "large surface area and prominent colors" as high quality requirements, which cannot meet customer requirements. Is it really difficult to control the appearance quality of products?

In fact, each silicone manufacturer has its own set of methods and experience for quality control of silicone products, and traditional methods are more effective than conventional ones. In fact, in principle, strict control of the appearance quality of products from the aspects of human, machine, material, environment, and method can basically solve the problem of product defects. However, in terms of the current environment, machine, and processing methods of most silicone manufacturers, there are still certain defects that cannot fully control the quality of products, such as the following points:

1. The machine and products are dead, while people are alive, so personnel operation and methods are certainly important. The entire process needs to be thoroughly studied on how to place the rubber material and how to take the mold during the processing.

2. The adjustment of the machine can yield good results even for products that are difficult to produce. Therefore, for machine parameters, it is necessary to adjust them according to the quality of your product to achieve the best effect.

3. Source control is crucial. If there are too many black spots and impurities in the purchased raw materials, it is even more impossible to guarantee the appearance of good products in subsequent production and processing. Secondly, strict control of adhesive paper and machine hygiene during the mixing process is crucial

4. The environmental hygiene issues in the production workshop are the main ones. If the environment in the production workshop is chaotic, there are problems with uncontrolled workshops, and the environmental hygiene of machine personnel, then the products produced will naturally not have good quality.

In short, there are many methods for appearance defects and other defects, and perhaps the root cause cannot be found among them. Therefore, it is still necessary to explore the methods.
