It is recommended to dry in air at 120°C, 6 ~ 8 hours, or 150°C, 2 ~ 4 hours. The humidity must be less than 0.03%. If drying with a hygroscopic dryer, the recommended conditions are 150°C for 2.5 hours. PBT Electrician tools mould molding Melting temperature: 225~275°C, recommended temperature: 250°C. PBT Electrician tools mould molding Mold temperature: 40 to 60°C for unreinforced materials. The cooling channel of the mold is well designed to reduce the bending of the plastic part. The loss of heat must be fast and even. It is recommended that the mold cooling channel has a diameter of 12 mm. PBT Electrician tools mould molding Injection pressure: medium (up to 1500 bar). PBT Electrician tools mould molding Injection speed: The injection speed should be as fast as possible (because PBT solidifies quickly). Runners and gates: Circular runners are recommended to increase pressure transfer (empirical formula: runner diameter = plastic thickness + 1.5mm). Various types of gates can be used. Hot runners can also be used, but care should be taken to prevent leakage and degradation of the material. The gate diameter should be between 0.8 and 1.0*t, where t is the thickness of the plastic part. If it is a submerged gate, the recommended minimum diameter is 0.75mm. PBT Electrician tools mould molding is a linear thermoplastic saturated polyester having an ester bond in its main chain, and its chemical name is Polybutylene Terephthalate, abbreviated as PBT, which is a polymer of the same class as PET resin. Since it has a high melting point and crystallinity, the water absorption rate and the coefficient of thermal expansion are also low, so that it has excellent dimensional stability. In addition, it has excellent electrical insulation, and the change in electrical properties caused by hygroscopicity is small, and the insulation voltage is high. There are crystalline regions and amorphous regions in the aggregate structure of PBT, and therefore, it is possible to easily modify and impart various functions by adding other substances. Various types of grades, such as flame retardant grades, high-speed molded grades, and high impact grades, have been given to various functions. Electronic components such as connectors, small switches, and capacitor cases, keyboards for OA machines, functional mechanical parts such as VTRs and telephones, automotive electronic components, and exterior parts such as door handles. Also, medical machinery, building materials, precision machinery, etc. are widely used in many of our daily necessities. Characteristic - The non-reinforced grade is tough, flexible and resistant to brittleness. - There are UL-rated flame retardant grades (94HB) and self-extinguishing grades (94-V-0, V-2), and their electrical properties are among the highest in thermoplastics PBT Electrician tools mould molding. - It has extremely low water absorption and long-term use over a wide range of temperatures and humidity. It also maintains excellent electrical properties. - The surface of the molded article is very smooth and has a low coefficient of friction. Due to the small amount of friction generated, it is suitable for applications requiring frictional wear performance. - The dimensional change during use is very small, and it is a highly reliable material that is excellent in molding stability and dimensional accuracy. - It has excellent long-term chemical resistance. At normal temperature, except for strong chemicals, there is almost no performance degradation during long-term immersion. - Not only the non-reinforced grade, but also the enhanced grade has excellent fluidity and excellent moldability. - By using a technique of blending with other polymers, a polymer alloy that satisfies various performance requirements has been developed PBT Electrician tools mould molding.
