How to solve the problem of large parting line of silicone rubber products?

In the silicone rubber products industry, the quality of silicone products sold to consumers is mainly determined by the texture and neatness. Self removal is the core factor of silicone products. The thickness and perfection of the product's surface lines determine its beauty. Why do many silicone daily necessities choose the grinding process to treat the parting line? It is official because the appearance parting line is completely removed. In the production process of silicone rubber products manufacturers, the parting line of the mold is inevitable. All product series products will produce parting lines, and there are many ways to deal with and avoid them. The specific needs to see from which aspects to start!

1. The core reason for the size of the parting line mainly comes from the mold. For example, the mold achieves the perfection of the product parting butt joint in terms of workmanship, and the parting line of the product will also be very thin. Therefore, the selection of steel products in the process of making the mold is very important. The steel affects the loss of the product after long-term pressing. The better the quality guarantee period of the steel parting line, the second is the accuracy of the CNC computer gong machine, Of course, the accuracy of the milling cutter and the adjustment of the cutter compensation are the key. If the upper and lower mold closing lines of the mold are well prepared, the product will naturally have a good self stripping edge line in the manufacturing process, and the more beautiful the product will be.

2. Production and processing belong to the internal control of silicone rubber products. If the manufacturer of silicone rubber products does not control the weight of materials during processing, it is likely to lead to too much burr extrusion and too thick parting line. Secondly, the level of the machine and the parameter control of the machine, such as pressure, exhaust and temperature, have a certain impact.

3. Material is the key to the thickness of the parting line of silicone rubber products. Generally, good materials will not have indirect fracture, serration and softening in the process of edge removal in the subsequent process, and it is estimated that it will be difficult to remove the edges if the parting line of the mold is poor when the silicone rubber material with high tensile force is cured, In addition, if there is a sticky roller or a material with high viscosity when mixing rubber, the jagged lines may appear during edge removal.

4. The structure problem is very important. In many cases, the parting line is usually made in some invisible positions because of the need to make the appearance of the product more beautiful. Such a structure is likely to increase the complexity and production difficulties of the mold. In addition, after long-term production, the parting line will become thicker and the appearance of the product will become more and more ugly, However, the main reason is that the subsequent molds can not be repaired and disassembled after the self disassembly wire changes of many structures, resulting in the damage of molds that cannot be repaired, and the molds will be scrapped over time!
