Silicone products how to remove the mold line?

What are the methods of silicone products to close the mold line? How do silicone products go to the mold line? To understand this, we must first understand the concept of the closing line, small series to tell you what is the closing line. Closing line, is the terminology of the mold in the line, refers to the convex, concave mold referred to as the upper and lower mold and two molds compressed together this is called closing mold. The interface line that will appear in the mold closing place after compression molding is called the mold closing line.

Generally, as long as it is open two pieces of inverted mold molding or injection molding products will appear the situation of mold line! So the mold line will directly affect the appearance of silicone products, for the mold line we have what methods to deal with it?

Silicone products to the mold line method 1: The use of flow polishing machine for grinding: this machine is a flow grinding method with higher grinding efficiency, composed of stepless speed regulation motor, fixed grinding cylinder and rotary chassis, driven by the rotary chassis, the internal material mechanical energy movement, the formation of eddy flow, in a short time to complete the grinding and polishing. Can the product mold line repair especially beautiful!

Silicone products to the mold line method two: the use of high-speed trimming gun, you can use the high-speed trimming gun to play the running-in mold line! But this grinding up a little troublesome, more manpower!

Silicone products to the mold line method three: The use of grinding and polishing machine, polishing machine is also known as grinding machine, often used as mechanical grinding, polishing and waxing. The working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed, because the polishing disc and polishing agent work together and friction with the surface to be polished, and then can achieve the purpose of removing paint pollution, oxidation layer and shallow marks. The speed of the optical disc is generally 1500-3000 r/min, mostly stepless variable speed, which can be adjusted at any time according to the need during construction.

Silicone products to the mold line method four: The silicone products are put into the grinder and the small particles of the grinding stone, the water is put into the grinding stone, the grinding machine is equipped with water and sand in the grinder bucket, the high-speed stirring, the grinder has a certain grinding, polishing characteristics, and the silicone products are rubbed back and forth with the sand and stone during the mixing process, the self-disassembly of the product and some surface defects are removed, which can achieve the grinding effect and mirror effect!

Now many customers are based on the appearance of silicone products to determine the quality, and the raw edge problem can be recognized at a glance, so the most obvious nature is the most important part, and the problem about the raw edge self-removal is mainly caused by two factors! First of all, whether there are corresponding measures in the cutting of the product, at present, if you want to maintain the yield and high quality of the product, you have to carry out artificial trimming, and the efficiency of artificial trimming is slow, and the quality is not fixed at all, and if you want to solve the problem of raw edges, you need to control the weight of the raw materials in the vulcanization process, and the raw edges around the self-removing edges will naturally increase and thicking. So to control the weight of the product is to control the quality of the product!

On the other hand, the accuracy of the mold, the upper and lower precision of the mold fails to reach the corresponding spacing, the raw edge and self-dismantling of the product will be thickened. And the gap between the mold line is too small to open the mold, so the difficulty of self-dismantling is here, to make a good self-dismantling and mold line is to determine the quality of the product is good, and a mold if the raw edge of the product is treated to be perfect, it also reduces a lot of trouble for the product in manual trimming treatment!
