Flow sink mold is through the use of engineering plastics polypropylene injection molding machine, but you need to set a good iron mold injection molding machine specifications and customers by providing full compliance with drawings after the start of injection to produce the same flow specification drawings sink mold. Flow sink mold has been widely applied to our lives, then sink mold flow characteristics which processes it, we take a look at it. Flow sink mold manufacturing generally go through forging, machining, heat treatment, several processes. To ensure the flow sink mold manufacturing quality, reduce production costs, the material should have good malleability, machinability, can grind, etc., should also have a small oxidation, decarbonization sensitivity. Has a low flow sink mold forging deformation resistance, plastic, forging a wide temperature range, forging crack cold cracking and low precipitation tendency carbide network. Flow sink mold ball annealing temperature range, low annealing hardness and small fluctuation range, the ball higher. Flow sink a large amount of mold shavings, tools, low loss, low surface roughness, good antioxidant properties when heated to high temperatures, slow decarbonization of the heating medium is not sensitive to small pitting tendency.
