PBT processing technology: the fastest filling speed of PBT generally lengthens the process, which is suitable for filling thin-walled profiles and forms a good surface finish. For thick walled products, slow filling helps to reduce voids. When narrow gate is used in PBT, the filling speed of thick wall section should be reduced to help maintain pressure. For parts with small gate (needle shaped gate), programmed injection is recommended, Injection volume: the recommended injection volume is 35% ~ 85% of the machine capacity. For mixed brands with strict color control, the injection volume should be close to 63% of the machine capacity, To reduce residence time
PBT发展概述：PBT在1970年代初期由美国Celanese公司研究成功，并以Celanex商品名上市，随后世界厂商德国BASF、Bayer、美国GE、Ticona，日本Toray、三菱化学，台湾新光合纤、长春人造树脂、南亚塑料等公司先后投入生产行列，全球生产厂商共计三十余家。PBT又可称为热塑性聚酯塑料，为适用于不同加工业者使用，一般多少会加入添加剂，或与其它塑料掺混，随着添加物比例不同，可制造不同规格的产品，目前岛内规格有百余种，故PBT是一种量少、规格多的产品。
Manufacturer: in 1970, tycona company in the United States commercialized it for the first time. The world's major brands include basic innovative plastics of the United States, crastin of DuPont of the United States, of Baoli, novaduran of Mitsubishi engineering of Japan, toraycon of toraycon of Japan, ultradur of BASF of Germany, pocan of Langsheng of Germany and celanex of tecona of the United States. The main manufacturers in China are Changchun, Xinguang and Nanya in Taiwan, which are widely used in China It's PBT in Changchun, Taiwan.
PBT is widely used in electronic and electrical fields, accounting for 50% of the total production of PBT: Computer / electrical connector, contactor, coil framework, connector, relay, fuse, regulator, temperature control switch, temperature control protector, decorative lamp holder, switch socket, induction cooker chassis, heater outlet, radiator fan wing, transformer coil framework, high voltage and high current Voltage break switch framework, computer fan, energy-saving lamp cap, electrical switch, electronic ballast , hair dryer, electric oven, rice cooker, microwave oven, water pump accessories and electric tool accessories, etc.; the application of PBT in automobile field accounts for 30% of the total production of PBT; it is mainly used for distributor cover, rotor, ignition coil cover, wiring terminal and transmission of high-voltage contactless igniter Sensor box, front and rear lamp holder, integrated circuit box, micro motor back cover, air-conditioning fan, etc. the application of PBT communication field accounts for 20% of the total production of PBT. It is mainly used in the integrated module, wiring board, capacitor and antenna sheath of program-controlled telephone
