Описание
Поскольку ПТФЭ не течет при температуре выше точки плавления, его нельзя лить под давлением, и для этого требуются специальные методы обработки. Формованный ПТФЭ обрабатывается путем прессования порошка сначала в заготовки, а затем спекания заготовок в процессе, аналогичном обработке спеченного металла. Этот процесс создает геометрические формы, которые затем можно обрабатывать, сплавлять и/или сваривать.
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.)
Product Description for Compression Molding:
The SuKo molding department has the capability to produce compression molded PTFE rod and tube stock to meet and exceed your exact specifications and tolerances. SuKo 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 SuKo already possesses.
With an extensive array of in-house equipment, SuKo is your one-stop source to handle all aspects of your compression molding component requirements. Call the specialists at SuKo for immediate assistance.
The knowledgeable SuKo staff can work with you from initial concept, through to design, production and finish. With our expertise in a wide range of plastic materials, SuKo can recommend the best plastic resins, plastic compounds and fillers to maximize performance and be cost-effective in your specific application. Contact the SuKo staff and see if automatic molding is suitable and economical for your application.
