Wax material hpe lang ai shaloi, melt mold casting hpe "lost wax casting" ngu nna mung shamying ma ai. Melting mold casting ngu ai gaw, n-gun rawng ai arung arai ni hte galaw da ai casting masing hpe tsun mayu ai, hkrang ntsa hta n-gun n rawng ai arung arai ni hpe layer law law hpe shinggrup nna, hkrang hte htum mat ai shingnip hpe hka lim kau ya ai, dai hku nna, casting hpe garan ginhka ai lam n lawm ai sha lu la na matu, nbung n-gun kaba ai shara ni hpe shinggrup ngut ai hpang, nhpu hpe jahpring nna ru bang na matu. Hpa majaw nga yang, dai hkrang hpe wax arung arai ni hta grai lang ai majaw, melting mold casting hpe " mat mat ai wax casting ngu nna shamying ma ai.
Melting casting hpe sum mat ai wax ladat ngu nna mung shamying ma ai. Wax hpe sum mat ai ladat gaw, n-gup magap hpe galaw na matu wax galaw nna, wax mold ntsa kaw nhpu hte ka-up da ai, ndai gaw nhpu n-gun rai nga ai. Mud mold hpe hkyet kau ngut ai hpang, ceramic mold kata de bang dat u.
