PA6 Product Friction Abnormal Noise

PA6 friction parts 'design according to wet-state dimensions': water absorption expansion changes clearances; the clearance of nylon friction parts must be designed according to the use state (wet state), not the dry state.

Material Drying PA6; gears; abnormal noise; water absorption; clearance

PA6 and PA66 Mixed Machine Material Change

PA6/PA66 material change = 'temperature system switching': applying parameters is strictly prohibited; the 40℃ melting point difference determines that material change must reset the temperature and thoroughly replace, and cannot seek convenience.

Processing Machinery PA6; PA66; material change; temperature; plasticization
