Do you know? Burr and appearance treatment is a process that every product needs to deal with, but the final silicone products you see is not as perfect as you think, but through layers of process. In the silica gel industry, the processing of the burrs is the most troublesome and the biggest shortcoming of the manufacturing industry, which leads to the worry of the mold making for the self edge removal, and the production of products worry about its edge compound, and worry about the bad products and so on.

Hanchuan silica gel factory senior engineer Wong told us that the edges of the treatment can be divided into the method and process of different, generally a lot of silicone products manufacturers are using manual trimming, the main advantage of this method is the product from the stitches do limit the products to reach off automatically flash effect, finally can be slightly artificial pruning, the is able to cope with a small number of. In the face of some small parts of the silica gel, when, and how to clean up the flash silica factory? Small size and large number of products, this time the mechanical trimming is the best way, adjust the size of automatic machinery through flash flash down position will break, and can handle large quantities, the efficiency is relatively fast, but is different from the manual in want of perfection of mechanical cleaning, the size is not controllable, adverse rate is not low die, and since the demolition is not good enough, the corner parts also need to manually fix.

The last is for high precision precision, good appearance of art products, it will need to be refrigerated trimming to meet the requirements, the reason is frozen trimming at low temperatures, where the thinnest product will fall off automatically according to the temperature embrittlement of flash, this method for silicone products is not very common, but usually a lot of precision rubber parts, rubber seals and so on are the frozen trimming process!
