Some consumers buy silicone products, found that the edge of the phenomenon of damage and cracks, which often makes many friends confused, resulting in the cognitive needs of silicone products and the lack of a certain purchase rate, but the edge of the silicone products fracture phenomenon has no choice.
The edge fracture of silicone products is called "edge explosion" in the silicone product industry, which is caused by several phenomena. During use, the product is affected by severe stress and mold, resulting in slight damage to the silicone product, resulting in subsequent grinding. Secondly, the product itself has its own damage phenomenon. During the production and processing of silica gel, the language problem of temperature and material fixation has led to the damage of the product. In addition, the hardness and softness of the product and the shape of the arc also have a certain impact. Therefore, the damage to the product can be controlled in all aspects of the reason!
1, hardness problem: low hardness silicone products explosion edge is more common, the main phenomenon of low hardness is the parameter configuration of silicone products manufacturers. Such as: machine temperature and secondary exhaust problems, so it is very important to establish mechanical parameters. The vulcanization temperature is reduced, the vulcanization time is shortened, and the molding and processing time of the product is controlled in the curing stage. If the time is too long, the raw material will expand. Causing the separation mode to separate, leading to rupture.
2. Raw material problem: Raw material is the key to silicone products. If the raw materials are not mixed at a certain time during the production process, or some auxiliary materials are added, it may cause various problems in the production process, such as edge explosion, poor fluidity, and product expansion. And deformation.
3. The structure is more complicated: the broken edge of the product is also relatively large. In addition to the hardness, the edge explosion phenomenon of silicone products is usually related to the structure of the product under low hardness conditions. For example, the product is thicker and has a certain degree of arc at the highest point of the product. And parting position, so the parting position must be strictly controlled at the same time in product design.
4. The mold is the key to the edge damage of silicone rubber products. At the same time, how to solve the problem of product damage caused by inconsistent docking of upper and lower parting points during the mold development process requires strict control of mold processing.
Finally, some special factors can also lead to the edge explosion phenomenon of the product, such as: the weight of the compound is not well controlled (too heavy will lead to the edge explosion phenomenon of the product, too light will lead to the lack of material and angle phenomenon of the product, so the probability of edge explosion is reduced to a reasonable weight. In addition, in the case of long-term uninterrupted production, the mold temperature should be appropriately reduced to keep the mold within a certain temperature range. Generally, clean water can be used to properly spray the mold, uninterrupted spray, in order to maintain the temperature of the mold.
