PBT注射材料
<110-120°C持续约3小时，成型加工温度为250-270°C，模具温度应控制在50-75°C。由于材料从熔融状态冷却，会立即凝固结晶，因此冷却时间短；如果喷嘴温度控制不当（较低），流道（喷嘴）容易冷却和固化，会出现堵塞现象。如果料筒温度超过275°C或熔融材料在料筒中停留超过30分钟，则很容易导致材料分解并变脆。PBT注射成型需要更大的喷嘴才能进入胶水。不适合使用热流道系统。模具必须通风良好。建议使用“高速、中压和中温”条件进行成型。回收时，应在机器停机时及时用PE或PP材料清洁料管，避免碳化

Product Details
PBT injection material
PBT injection molding must be dried at a temperature of 110-120°C for about 3 hours, the molding processing temperature is 250-270°C, and the mold temperature should be controlled at 50-75°C. As the material is cooled from the molten state, it will immediately solidify and crystallize, so its cooling time is short; if the nozzle temperature is not properly controlled (lower), the flow channel (nozzle) is easy to cool and solidify, and a plugging phenomenon will occur. If the barrel temperature exceeds 275°C or the molten material stays in the barrel for more than 30 minutes, it is easy to cause the material to decompose and become brittle. PBT injection molding requires a larger nozzle to enter the glue. It is not suitable to use a hot runner system. The mold must be well vented. It is advisable to use “high speed, medium pressure, and medium temperature” conditions for molding. For recycling, PE or PP material should be used to clean the material pipe in time when the machine is shut down to avoid carbonization.
