Plastic molding ngu ai gaw, plastic ni hpe plastic arung arai ni de galai shai na matu, ladat amyu myu hpe jai lang ai engineering hpaji langai rai nga ai. Ndai galai shai ai aten hta, lawu na langai (sh) law law byin chye ai: polymer rheology hte hkum hkrang hte tsi mawan ni hta galai shai ai lam ni.
N-gun shayawm ai
Compression hku galaw na matu madung lang ai arung arai gaw, press hte mold re. Grau nna lang ai press gaw, shi hkum shi-hkum tsup ai hydraulic press rai nna, ton shi kaw nna latsa du hkra n-gun rawng ai. Lawu -pressure hte ntsa-pressure ni nga ai. Compression molding galaw na matu lang ai mold hpe compression mold ngu shamying nna, dai hpe masum garan nna, n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai n-gun rawng ai re. Compression molding a madung akyu ni gaw, n-gup magap kaba ai arung arai ni hpe mold galaw lu nna, law law galaw shapraw lu ai majaw re. Shi a hkra machyi ai lam ni gaw, galaw shapraw ai aten galu ai hte n-gun n law ai.
Katsi htu ai
Lamination galaw ai shaloi, lamination press hpe lang ai. Ndai zawn re ai press hta shamu shamawt nga ai hte n shamu n shamawt nga ai pressure plate lapran hta lwi nga ai hot press plate law law nga ai. Lamination galaw ai hta lang ai n-gun ja ai arung arai ni gaw, cotton hpun nba, glass hpun nba, laika man, asbestos hpun nba ni rai nga ai. Resin ni hta phenolic n-gun, epoxy n-gun, n-gun n rawng ai polyester n-gun, thermoplastic n-gun nkau mi lawm ai. Injection hte n-gun dat ai, extrusion hte n-gun dat ai, n-gun dat ai, film n-gun dat ai, hot melt n-gun dat ai, fluidized bed n-gun dat ai, wan n-gun dat ai, electrostatic n-gun dat ai, plasma n-gun dat ai.
Hprawng shapraw ai
Extrusion molding ngu ai hpe extrusion molding (sh) extrusion ngu nna mung shamying ma ai, dai gaw lwi nga ai masa hta die hku nna matut manoi galaw shapraw ai ladat rai nna, dai hpe extruder kata kaw katsi shangun nna n-gun dat dat ai ladat re. Extrusion hpe madung hku nna thermoplastic ni hpe galaw na matu lang ai raitim, n-gun n rawng ai plastic nkau mi hpe mung lang mai ai. Extruded galaw ai arung arai ni gaw, matut manoi nga ai profile ni rai nna, pipe, rod, filament, film, hte wire hte cable ni hpe shinggrup da ai zawn re ai ni rai nga ai. Dai hta n-ga, plastic hpe kayau ai, plastic galaw ai granulation galaw ai, nsam bang ai, nsam bang ai hta mung lang mai ai. Extrusion molding machine hta, n-gun dat shapraw ai arung arai ni, n-gun dat dat ai ladat, n-gun dat hte katsi ai ladat ni lawm ai. Extruder ni gaw screw amyu (screw langai hte law law-screw) hte plunger amyu lahkawng nga ai. Shawng na gaw matut manoi shapraw ai lam rai nna, hpang na gaw aten kadun laman galaw ai lam re. Screw extruder langai a madung hkrang gaw madung hku nna, n-gun dat dat ai jak, lusha jaw ai jak, barrel, screw, die head, die ni lawm ai. Extruder ni a matu karum shingtau ai arung arai ni gaw madung daw masum hta garan nna, arung arai ni hpe shawng gram lajang ai arung arai ni (material htaw sa ai hte hkyet mat ai zawn re ai), extrudate hpe galaw ai arung arai ni (shaping, cooling, traction, cutting, or rolling), hte galaw shapraw ai masa hpe hkang ai arung arai ni rai nga ai.
Pultrusion hkrang shapraw ai
Pultrusion gaw n-gun ja ai fiber-n-gun ja ai plastic ni hpe n-gun ja hkra galaw ai ladat langai mi rai nga ai. Dai hpe n-gun n rawng ai cross-sectional hkrang hte n-htum n-wai galu kaba ai profile ni hpe galaw na matu lang ai. Molding galaw ai ladat hta, n-gun ja ai die hku nna, n-gun ja ai die hku nna, resin hte n-gun rawng ai matut manoi n-gun rawng ai n-gun ni hpe sumla hkrung galaw nna, dai n-gun rawng ai n-gun hpe n-gun ja ai nta kata kaw grau nna n-gun ja ai, unidirectional high-n-gun ja ai matut manoi n-gun ja ai plastic profile hpe shapraw lu na matu galaw ra ai.
Pultrusion hpe galaw na matu lang ai resin ni hta n-gun n rawng ai polyester, epoxy, silicone ni lawm ai. N-gun n rawng ai polyester resin hpe grau nna lang ma ai. Pultrusion molding jak hta, laksan hku nna, n-gang hpe lajang da ai jak, resin tank, preforming jak, die hte katsi ai jak, traction jak, hte htum mat ai jak ni lawm ai.
