In the silicone rubber products industry, the quality of silicone products sold to consumers mainly depends on the texture and the degree of neatness. The core factor of silicone products is self dismantling edge. The thickness and perfection of the surface lines of the products The degree determines its beauty. Why do many silicone daily necessities choose the grinding process to process the parting line? The formal reason is that the appearance parting line is completely erased, and in the production process of silicone products manufacturers, the mold is divided into two parts Mold line is inevitable, all product series will produce parting line, and there are many ways to deal with and avoid it, the specific need to see from which aspects to start processing!

How to improve the quality of silica gel products

The core reason for the size of parting line mainly comes from the mold. For example, in the aspect of die making, the parting line of the product will be very fine, so the steel of the product in the process of mold making will be very fine Selection is very important. The steel affects the long-term wear and tear of the product after pressing. The better the steel parting line is, the better the shelf life of the steel parting line is. The accuracy of the CNC computer gong machine platform is the second. Of course, the accuracy of the milling cutter and the debugging of the cutter compensation are the key points. If the upper and lower mold closing lines of the mold are done well, the products will naturally have good self detachable edges, and the more beautiful the products will be.

The production and processing belongs to the internal control problem of silica gel products. If the silica gel product manufacturer does not control the weight of the material during the processing, it is likely to cause too much burr extrusion and too thick parting line, followed by the level of the machine and the control of machine parameters, such as pressure, exhaust and temperature, etc., which have a certain impact.

The material is the key to the thickness of the parting line of silica gel products. Generally, the better materials will not appear indirect fracture, serration and softening phenomenon in the subsequent process of edge removal, and the silica gel material with higher tensile force will be solidified If the parting line of the mold is poor, it is estimated that it will be difficult to remove the edge, and if the material is sticky to the roller or the material with high viscosity during the process of rubber mixing, serrated lines may appear.

The structure problem is very important. Because of the need to make the appearance of the product more beautiful, the parting line is usually placed in some invisible position, which may increase the complexity of the mold And production difficulties, and after a long period of production, the parting line will become thicker and thicker, and the appearance of the products will become more and more ugly. However, the main reason is that the subsequent mold can not be repaired and disassembled after many structural self removal changes, resulting in the mold damage can not be repaired, and the mold will be scrapped for a long time!
