Molding chu polymer chi hrang hrang (powder, pellet, solution emaw dispersions) duhthusam ang chiaha siam chhuahna a ni. Plastic material molding process zawng zawngah a pawimawh ber a, polymer material emaw profile zawng zawng siam chhuahna a ni. A tul anga kalpui dan tur. Plastic molding hman danah hian extrusion molding, injection molding, compression molding, transfer molding, laminate molding, blow molding, calender molding, foam molding, thermoforming leh hmanraw dang tam tak a awm a, chung zawng zawng hian an adaptability an nei vek a ni.
Thermoforming hmanga siam a ni tih hi thermoplastic sheet hmanga thil siam chhuah dan a ni a, hei hi plastic secondary molding vang a ni thei. A hmasa berin, sheet size leh shape engemaw zat a cut chu mold frame-ah dahin, Tg-Tf inkar elastic state sang takah dah a ni a, sheet chu a lum laiin a hrual a, chutah chuan pressure chu mold hnaih taka siam turin an dah a Shape surface chu shape surface nen a inang a, chu product chu cooling, shaping leh trimming hnuah hmuh theih a ni. Thermoforming neih lai hian pressure pek hi a bik takin sheet sir lehlamah vacuum leh compressed air dah luh atanga pressure danglamna siam a ni a, mahse mechanical pressure leh hydraulic pressure hmanga siam a ni bawk.
Thermoforming ziarang chu forming pressure a hniam a, thermoforming process chu hetiang hi a ni:
board (sheet) material → clamping → tihlum → pressure → cooling → shaping → semi-finished products → tihlum → trimming. A siam zawh tawh thermoforming hi vawi khata hman theih tur, injection molding leh extrusion ang chi te nen a danglam a ni. Plastic resin emaw pellets emaw, heating molding emaw, die hmanga cross-section inang nei continuous molding emaw atan a ni lo; plastic material thenkhat chu machine tools, tools leh mechanical processing method dang hmanga tan pawh a ni lo. A dawtah chuan a mamawh ang chi leh a size hmuh theih nan, mahse plastic board (sheet) material atan chuan, heating, mold, vacuum emaw pressure hmanga board (sheet) material deform turin. A mamawh ang shape leh size thleng, supporting procedures hmanga tihpun, application tum tihhlawhtlin nan.
Thermoforming technology hi metal sheet siam dan hmanga siam a ni. A siam chhuah hun rei lo mahse, a processing speed a rang a, automation degree a sang a, mold pawh a man tlawm a, thlak a awlsam a, a adaptability pawh a chak hle. Vanlawng leh car part ang maia lian, in tur cup ang chi thil te a siam thei a ni. Leftovers hi recycle a awlsam hle. 0.10mm vela sei sheet te pawh a process thei. Heng sheet te hi transparent emaw opaque emaw, crystalline emaw amorphous emaw pawh a ni thei. Pattern chu sheet-ah print hmasak theih a ni a, a nih loh leh moulding zawhah pattern rawng hring tak tak print theih a ni bawk.
