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.)
  • Efficiency: While not fully automated, semi-automatic machines still reduce manual labor requirements compared to fully manual processes. This leads to improved production rates and reduced labor costs.
  • Flexibility: Semi-automatic machines allow operators to intervene when necessary, making adjustments for specific molds or production requirements. This flexibility is beneficial for handling diverse product types or custom orders.
  • Cost-effectiveness: Compared to fully automated systems, semi-automatic machines are typically more affordable to purchase and maintain. They offer a cost-effective solution for manufacturers with moderate production volumes or varying production needs.
  • Operator Skill Utilization: Semi-automatic machines leverage operator expertise and judgment, particularly in tasks requiring intricate mold setups or adjustments. This can result in higher quality outputs compared to fully automated processes in certain scenarios.
  • Adaptability: Operators can easily switch between molds or production setups, allowing for rapid adaptation to changing product demands or specifications. This adaptability enhances overall production efficiency and responsiveness to market dynamics.
  • Training Requirements: Semi-automatic machines generally require less specialized training for operators compared to fully automated systems. This can reduce training costs and shorten the learning curve for new personnel.

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.


The knowledgeable Sunkoo staff can work with you from initial concept, through to design, production and finish. With our expertise in a wide range of plastic materials, Sunkoo can recommend the best plastic resins, plastic compounds and fillers to maximize performance and be cost-effective in your specific application. Contact the Sunkoo staff and see if automatic molding is suitable and economical for your application.
