Lost form casting hmanrua .
Lost foam casting, chu chu full mold casting process a ni a, foam mold chu sand-ah a dah a, chutah chuan vacuum casting-ah a dah a, casting part ang chiah foam mold chu assemble la, chutah chuan refractory paint nen coating, silica sand-ah bury, vibration modeling hnuah negative pressure hnuaia casting, gasified foam mold, a lum hnuah, chutah chuan casting a awm ang. China ramah hian ductile iron pipe machinery tha ber ber kan nei a.
Lost foam casting a thatna chu:
Quality tha, man tlawm .
No limit on material, all size dimension sang tak, lei thianghlim, tihfai tlem, machining atana hun humhim; Technology thar siam dan dik tak, a kalphung chuan mold a lak a ngai lo, surface leh sand core, flash, burr leh draft angle tel lovin casting a mamawh a, core size hrang hrang inzawmkhawm avanga tihsual a tihziaawm bawk. Casting surface roughness hian RA3.2 atanga 12.5μm thleng a thleng thei a; Casting dimension dikna chu CT7 atanga 9 thleng a ni thei a; Machining allowance a tam berah 1.5 to 2 mm a nih chuan, traditional sand casting method nen khaikhin chuan, mechanical processing cost atanga 40% atanga 50% velin tihhniam theih a ni.
A chhunga chhiatna tlem zawk, compact structure .
Scale lian tak, batch lian tak tak siam chhuah, automatic production, eco-friendly.
Production environment a ti tha thei a, labour hardness a ti tlem thei a, energy hman a ti tlem thei bawk.
Cleaner siam chhuah: Green sand binder-ah chemistry a awm lo, boruak tana hlauhawm lo, low temperature foam sand recovery 95% aia tam.
