PBT塑料树脂
产品详细信息
工艺参数①注射温度：PBT的分解温度为280℃，因此在实际生产中一般控制在240-260℃之间
②注射压力：注射压力一般为50-100MPa
③注射速率：PBT具有较快的冷却速率，因此应使用较快的注射速率
④ 螺杆转速和背压：成型PBT的螺杆转速不应超过80r/min，一般在25到60r/min之间。背压一般为注射压力的10%到15%
⑤模具温度：一般控制在70～80℃，各部位温差不超过10℃
⑥ 成型周期：正常情况下15～60秒。

Process parameters
①Injection temperature: The decomposition temperature of PBT is 280℃, so it is generally controlled between 240-260℃ in actual production.
②Injection pressure: The injection pressure is generally 50-100MPa.
③Injection rate: PBT has a fast cooling rate, so a faster injection rate should be used.
④ Screw speed and back pressure: The screw speed for forming PBT should not exceed 80r/min, generally between 25 and 60r/min. The back pressure is generally 10% to 15% of the injection pressure.
⑤Mold temperature: generally controlled at 70～80℃, the temperature difference of each part should not exceed 10℃.
⑥ Molding cycle: 15～60 s under normal circumstances
