Plastic PTFE Semi-Automatic Molding Machine

Since PTFE will not flow above its melting point, it cannot be injection molded and requires special processing techniques. Molded PTFE is processed by first compression molding the powder into preforms, and then sintering the preforms in a process analogous to sintered metal processing. This process creates geometric shapes that can then be machined, fused, and/or welded.

Product Description for Automatic Molding:

Automatic molding, a semi-automated form of compression molding, is the process Suko uses for the manufacture of medium-volume to large-volume net molded and near net molded PTFE components. The automatic molding process requires dedicated tooling, typically requires minimal operator intervention and plastic parts can be fabricated relatively rapidly.

With the use of precise tooling and processing, parts manufactured using the automatic molding process can be produced to relatively close tolerances, but not to the accuracy of a fully machined part. Components are economically molded by utilizing a process of automated filling of the die cavity, applying pressure, and part ejection.

Other advantages of the Automatic molding process include:

· Little or no scrap material as compared to the “typical” PTFE machining process from stock shapes (rod or tube)

· Lower part cost, with minimal or sometimes no machining steps required

· Components that are molded and sintered into final forms and shapes have reduced stress defects compared to machined parts (from cutting, milling, etc.)

Applications:

• Sealing and gaskets: PTFE is an excellent sealing material due to its low coefficient of friction, chemical resistance, and temperature stability. Semi auto molding machines are used to produce seals, gaskets, and O-rings for various applications.
• Electrical insulation: PTFE has high electrical resistance and is used in electrical components such as insulators, connectors, and terminals. Semi auto molding machines can produce complex shapes with precise dimensions.
• Medical devices: PTFE is biocompatible and chemically inert, making it suitable for medical applications. Semi auto molding machines are used to produce medical implants, surgical instruments, and diagnostic equipment.
• Chemical processing: PTFE is resistant to a wide range of chemicals and is used in chemical processing equipment such as valves, pumps, and pipelines. Semi auto molding machines can produce parts with high chemical resistance and durability.
• Food and beverage: PTFE is non-toxic and FDA-approved for food contact. Semi auto molding machines are used to produce food processing equipment, packaging materials, and containers.
• Aerospace: PTFE is lightweight and has excellent thermal and mechanical properties, making it suitable for aerospace applications. Semi auto molding machines can produce components for aircraft, satellites, and spacecraft.

Advantages of Semi Auto Molding Machines:

• Increased efficiency: Semi auto molding machines automate part of the molding process, reducing labor costs and increasing production speed.
• Improved accuracy: Semi auto molding machines use precise molds to produce parts with consistent dimensions and high quality.
• Reduced waste: Semi auto molding machines minimize material waste by using precise mold cavities and automated material feeding systems.
• Flexibility: Semi auto molding machines can be used to produce a wide range of parts with different shapes and sizes.
• Cost-effectiveness: Semi auto molding machines offer a balance between automation and manual labor, providing cost-effective production for medium to high volume applications.

Product Description for Compression Molding:

Sunkoo offers compression molding of PTFE for the manufacturing of material shapes for production of your custom plastic component. Compression molding is a molding method where the resin powder is subjected to substantial straight line forces in a closed die set to create solid rod or tubular shapes.

The Sunkoo molding department has the capability to produce compression molded PTFE rod and tube stock to meet and exceed your exact specifications and tolerances. Sunkoo has over 1,000 mold sizes to manufacture stock shapes from 1” OD to 26” OD in Virgin PTFE, as well as all industry standard and custom blended materials. One of the benefits of compression molded rod or tube is the relatively low cost of this method. It typically does not require special tooling beyond what Sunkoo already possesses.

With an extensive array of in-house equipment, Sunkoo is your one-stop source to handle all aspects of your compression molding component requirements. Call the specialists at Sunkoo for immediate assistance.
