，因此，加工前的干燥处理非常重要。建议空气中的干燥条件为120°C，6~8小时，或1509°C，2~4小时。湿度必须小于0.03%。如果使用吸湿干燥器进行干燥，建议在150°C温度下干燥2.5小时。[2] 熔融温度：225~275°C，推荐温度：250°C。
无加强材料的模具温度：40~60°C。为了减少塑料件的弯曲，有必要设计好模具的冷却腔。热损失必须快速且均匀。建议模具冷却通道的直径为12mm
注射压力：中等（高达1500巴）
注射速度应尽可能快（因为PBT的凝固非常快）
流道和浇口：建议使用圆形流道来增加压力传递（经验公式：流道直径=塑料件厚度+1.5mm）。可以使用各种类型的浇注口。也可以使用热流道，但必须注意防止材料泄漏和降解。闸门直径应在0.8~1.0*t之间，其中路堤塑性部分的厚度。如果是水下闸门，建议小直径为0.75mm
用途：
电子电器：无熔丝断路器、电磁开关、反激变压器、家用电器手柄、连接器、外壳
汽车：门把手、保险杠、配电盘盖、挡泥板、钢丝护板、轮辋盖
工业零件：OA风扇、键盘、渔具卷筒、零件、灯罩

Process conditions
Drying treatment: This material is easily hydrolyzed at high temperatures, so the drying treatment before processing is very important. It is recommended that the dry condition in the air is 120°C,
6~8 hours, or 1509C, 2~4 hours. The humidity must be less than 0.03%. If you use a moisture-absorbing dryer to dry, the recommended conditions are 150°C for 2.5 hours. [2]
Melting temperature: 225~275°C, recommended temperature: 250°C.
Mold temperature: 40~60°C for unreinforced materials. It is necessary to design the cooling cavity of the mold well to reduce the bending of the plastic part. Heat loss-must be fast
And even. It is recommended that the diameter of the mold cooling channel is 12mm.
Injection pressure: medium (up to 1500bar).
The injection speed should be as fast as possible (because the solidification of PBT is very fast).
Runner and gate: It is recommended to use a circular runner to increase the pressure transmission (empirical formula: runner diameter = plastic part thickness + 1.5mm). Various types of pouring can be used
mouth. Hot runners can also be used, but care must be taken to prevent leakage and degradation of materials. The gate diameter should be between 0.8~1.0*t, where the thickness of the embankment plastic part. in case
It is a submerged gate, and the recommended small diameter is 0.75mm.
Advantages: 1. The mechanical properties are stable and the tensile strength is similar to the tensile modulus of nylon; 2. The friction coefficient is small and self-lubricating; 3. Low water absorption; 4. Excellent electrical properties; 5. Good dimensional stability; 6. , Resistance… quality, oil resistance; 7, high heat resistance, toughness, fatigue resistance, weather resistance
use:
Electronic appliances: non-fuse circuit breakers, electromagnetic switches, flyback transformers, household appliances handles, connectors, shells;
Automobiles: door handles, bumpers, switchboard covers, fenders, wire guards, rim covers;
Industrial parts: OA fans, keyboards, fishing tackle reels, parts, lampshades;
