Injection molding method for manufacturing sliding contact seal involves roughening molding tool surface to produce seal areas with rough surface quality |
摘要 |
<p>Surfaces(31) of the tool cavity(30) corresponding to the seal contact areas are roughened by blasting particles at them to produce a specific degree of surface roughness. A seal(11) is then molded which has sealing lip faces(32,33) having the roughness caused by the tool surface. Contact surfaces of the seal have a surface roughness (Ra) of 1.5 microns. Independent claims are included for: (1) a seal for sliding contact produced by the claimed method; (2) a hydraulic component in which the sliding contact areas between a piston and an associated bore are sealed by a seal produced as claimed.</p> |
