The mould is relevant knowledge one, the pattern is fundamental knowledge: 1, all sorts of tools that we use foreword in daily production, life and product, arrive greatly crust of the base of the machine tool, airframe, small to screw of an embryo head, button and the crust of all sorts of electric home appliancesThe advantage of system of road of ◆ thermal current (1) anhydrous mouth makings, after needing, machine, make whole shape the process is complete automation, save working hours, improve work efficiency. (2) pressure loss is small. Hot runner temperature shoots mouth temperature with the machine that note model equal, avoided raw material the exterior condensation phenomenon inside runner, inject pressure loss is small. (3) water mouth makings repeats use meeting to make plastic function degradation, and system of road of use thermal current expects without water mouth, can reduce the loss of raw material, reduce product cost thereby. Be in model the temperature in antrum and pressure are even, model stress is little, density is even, below lesser inject pressure, shorter shape inside time, note model to give better than the average system that note model product. To transparent, thin, large model or high demand model can show its advantage more, and can give older product with lesser type production. (4) hot nozzle uses design of standardization, seriation, deserve to have all sorts of nozzle heads that can offer an alternative, interchangeability is good. The report that designs treatment distinctly heats circle, can achieve heat temperature is even, service life is long. System of hot flow path deploys heat runner plate, lukewarm accuse implement etc, the design is exquisite, sort is diversiform, use convenient, quality is stable and reliable. The insufficient part that system of road of ◆ thermal current uses (1) integral mould closes height is increased, because add outfit heat runner board, mould whole height increases somewhat. (2) heat radiation is controlled hard, the mistake with hot the biggest runner is the loss of quantity of heat of runner, it is the major task that a need solves. (3) existence heat expands, heat bilges cold shrinking is the issue that the consideration wants when we are designed. (4) mould production cost raises, price of fittings of level of hot runner system is higher, affect those who heat up runner mould to gain ground. The company that ◆ provides standard component of hot flow path has: DThe company such as ME, HASCO, HUSKY, EOC, FULLY, MASTER-TIP, INCOE. When my department makes a pattern, system of hot flow path uses the brand that the client appoints commonly, if the client did not appoint a brand, my Sikegen compares general brand according to needing to choose, wait like DME, HASCO.
