PTFE Welding Parts
PTFE Welding Parts play a vital role in semiconductor wet-process systems and other high-purity manufacturing environments, where corrosion resistance, cleanliness, and reliability directly affect process yield and equipment life. Each component is fabricated from high-purity fluoropolymers such as PTFE, TFM, and PFA, welded into seamless structures that withstand aggressive acids, bases, and elevated temperatures. Their smooth, non-contaminating surfaces ensure the purity of chemical baths and deionized water rinses throughout wafer processing.
Typical welded products include PTFE tanks for chemical storage and cleaning, rectangular baths and overflow sinks for continuous wafer rinsing, and integrated tanks that combine circulation, drainage, and overflow functions in one design. In addition to these, ESI has the capability to fabricate virtually any welded PTFE, TFM or PFA component, such as barrels, wafer carriers, card guides, and crystal boat boxes, customized to match unique equipment and process needs.
