PRESS-MOLD FOR MOLDING ARTICLES FROM POWDERED FLUOROPLASTIC-4 MATERIAL

摘要

Use: the production in an aggressive environment resistant hollow metal articles with flanges, for example, pipes or drawer side column apparatus having an inner lining, formed by the resulting compression and subsequent sintering powder PTFE-4. SUMMARY OF THE INVENTION: the form includes a base 4, a cover in two parts 5 and 6, ring 7 and 8, respectively for pressing the upper and lower flanges of the lining. On the flange 3 of the article set removable metallic ring 12c of a height equal to the expected value of the longitudinal thermal shrinkage of the liner. 6 ZP f ly-2-yl. 56
