Plate (sheet) tih lum hnua forming hi thil pawimawh dang a ni a, chutah chuan technical parameter pawimawh tak tak, forming temperature, forming pressure leh forming speed te control a ni.
1 Temperature siam chhuahna
Material, process type leh equipment te an hriat hnuah forming temperature hi product quality tichhetu ber a ni a, hei hian product thickness tlem ber, thickness distribution leh dimensional error te direct takin a nghawng a, product elongation leh tensile strength pawh a nghawng a, forming speed pawh a nghawng bawk. Chuvang chuan ngaih pawimawh a tul hle a ni.
2 Pressure siam chhuahna
Pressure effect hian sheet chu a ti deform a, mahse material hian deformation do theihna a nei a, temperature a san chuan a elastic modulus a tlahniam bawk. Molding temperature-ah chuan, he temperature-a material-a pressure avanga stress awm chu he temperature-a material elastic modulus aia tam a nih chauhvin material chu a deform thei a ni. Temperature engemaw zat a pressure pek chu material elongation tling siam turin a tawk lo a nih chuan molding pressure tihsan emaw, molding temperature tihsan emaw chauhvin molding chu awlsam takin a siam theih a ni. Material hrang hrang elastic modulus hi a danglam a, temperature a innghat a inang lo avangin molding pressure hi polymer type (relative molecular weight telin), sheet thickness leh molding temperature a zirin a danglam thin.
3 Forming Speed tih a ni
A thil siamte wall thickness inang lo chhan ber chu: pakhatnaah chuan, formed sheet hmun tinte stretching degree a inang lo va; pahnihnaah chuan, stretching speed lian tham tak, chu chu air extraction leh inflation atanga gas flow rate emaw, mold, clamping frame leh pre stretching plunger kal chak dan emaw a ni. Forming speed tih hian plate (sheet) a drawing speed a kawk a ni. Forming speed tihsan hian forming cycle a ti tawi thei a, productivity tihsan nan a hlawkpui hle. Mahse, forming speed sang lutuk hian product quality a nghawng dawn a ni.
