Melting temperature: 230°C to 270°C
Mold temperature: 40-80°C
Injection pressure: 100-140 MPa
Extrusion
Extrusion is used to manufacture semi-finished PBT products such hong kong dataas sheets, rods and profiles. Molten PBT is forced through a die to create a continuous shape, which is then cut to the required length.
Blow molding
Blow molding is used to produce hollow parts such as bottles and containers. The process involves extruding a tube of molten PBT, which is then inflated inside a mold to achieve the desired shape.
Compression molding involves placing PBT pellets into a heated mold, which is then compressed to form the desired part. This technique is suitable for producing large, flat, or thick-walled parts.
3D printing
You can 3D print PBT plastic using techniques such as fused filament fabrication (FFF) and selective laser sintering (SLS). Although less common than other materials, 3D printing with PBT allows for the creation of complex shapes and prototypes with high strength and durability.
Advantages and limitations of PBT
Benefits
Excellent mechanical properties: PBT plastic exhibits high strength, stiffness and toughness, making it suitable for demanding applications where mechanical robustness is required.
Dimensional stability : It maintains its shape and size over a wide range of temperatures and in humid environments, ensuring reliable performance.
Low friction and wear resistance : This material is ideal for moving parts and sliding applications because it reduces the need for lubrication and improves durability.
Chemical Resistance : It is resistant to solvents, fuels and many chemicals, making it suitable for chemically harsh environments.
Electrical Insulation: PBT plastic offers high dielectric strength and low dissipation, giving it excellent electrical insulation properties for electronic components.
Ease of Machining: PBT is highly machinable, enabling the precise and complex manufacturing of parts, advantageous for detailed engineering applications.
