Engineering plastic PBT injection molding process:

(1) drying treatment: it can be dried for 3-4 hours at a temperature of about 100 ℃.

(2) injection temperature: 220 ℃ -250 ℃, injection pressure between 50-100mpa, with a faster injection speed.

(3) mold temperature: 60 ℃ -80 ℃, do not exceed 100 ℃. If necessary, silicone can be used as release agent.

Applications of PBT Plastics: PBT plastics are used in many car accessories, such as car ignition device switch, direction light, car tail light accessories, fuse box, ignition coil housing, rotor, carburetor, safety belt, gear box, car handle, connector, and can also be used in industries such as relay, rectifier, fan housing, LED fluorescent lamp holder, LED lamp cap, snowboard, water meter housing, water pump housing, flow controller Chemical liquid treatment device, home appliance shell, washing machine accessories, air conditioning accessories, mobiles phones parts, mobiles phones shell, mobiles phones protective cover, computer keyboard and key cap, etc.
