Popular science silicone products manufacturer, how to control the parting line and product flash
in the grocery department at ordinary times when you should have bought or defective items and counterfeit, fake goods which is in essence is actually a fake, but look from the side it is not a fake, it is possible that the problems and bad product, such as burr scraping the hand on the metal parts, plastic toys on the edge of the rubber and so on, more so in the silicone products is no exception, may be due to a temporary oversight to market became the fake goods.
in silicone rubber products industry, silicone molding and processing methods with a variety of other materials are the same in bulk and molding production, such as plastic, metal, ceramic, and so on, but the burrs and moulding line is its main defects, due to the silicone products molding processing is the mold in the raw material in the upper and lower clamping molding, so between the upper die and lower die will appear a parting line, and it is this one line may lead to influence consumers' first feeling!

mould first, completes the mold parting line is stepping out of the high quality of the first step, followed by the blanking grams of weight control of raw materials, such as the weight of materials beyond the scope of the flash butt make products, moulding line may also be a critical edge phenomenon, operation specification, material put evenly, ensure that materials from top to bottom and centered around not offset can guarantee product moulding line is in the best position, make product lines clamping can get good control.
