Plastic raw materials processing hi a bik takin rubber particles te chu setting hnua finished products ah melt, flowing leh cooling process a ni ber. A lum a, a hnuah a lum leh a ni. Plastic te chu particle atanga a pianzia hrang hranga thlak danglam dan a ni bawk. A tan chuan plastic hmanga siam thermoforming machine hmanga siam a ni, a kalphung zawng zawng hi kut hmanga hnathawh ngai lovin full-automatic operation atan a siam theih a, product quality pawh a stable hle! A hnuaia tarlan te hian stage hrang hrang thlirna atanga processing process kan sawifiah ang.
1. Melt a ni
Device heater hmang hian raw material particle te chu zawi zawiin fluid flow ah a inthlak thei a ni. Raw material hrang hrang hi temperature regulation atan a tha ber. Temperature tihsan hian raw materials a ti chak ang a, hei hian efficiency a ti sang thei a, mahse yield a tichiang hauh lo. Balance mumal tak neih a ngai a ni. Chu bakah, thermal cracking sang tak a awm chuan PP hian a nghawng tha leh a mizia chu a siam chhuah laiin raw material chu die-ah awlsam taka luang chhuak tura siam a tha ber a, chutiang chuan filling emaw reflux emaw tling lo a awm loh nan. Reflux tih awmzia chu raw material flow chu output rate aiin a rang zawk tihna a ni a, a tawpah chuan average flow efficiency a tisang a, hei hi MFR tihchangtlunna nen a inang a ni. Processing atana hmanraw awm zinga pakhat a ni a, Mahse, MFR distribution dik lo a thlen bawk a, chu chuan instability a tipung thei a, defect rate a tisang thei bawk. Mahse, a hman dan avang hian PP finished products hi dimensional precision sang tak nei product an nih loh avangin impact a lian lo hle.
2.Screw stem hmanga siam a ni
PP processing tam zawk hi chu fluidity khalh turin screw-ah a innghat a, chuvangin screw design hian nghawng lian tak a nei a ni. Diameter hian output a nghawng a, compression ratio hian pressure value a nghawng bawk. Output leh finished product effect pawh a nghawng a, chutah chuan thil chi hrang hrang (Color Masterbatch, additives leh modifiers) mixing effect pawh a nghawng tel bawk. Raw materials flow hi heater-ah a innghat ber a, mahse raw materials friction leh friction hian friction heat energy a siam bawk ang a, chu chuan fluidity a ti chak ang. Chuvangin screw compression ratio a tlem a, flow a tlem a, rotating speed pawh tihsan a ngai a, chu chuan compression ratio lian tak nei screw aiin friction heat energy a ti tam zawk a ni. Chuvangin plastic processing lamah hian master an awm lo tih an sawi fo thin a, machine hnathawh dan uluk taka hrethiamtu chu master a ni. Raw materials lumna hi heater mai ni lovin, friction heat leh suffocation time te pawh a tel a ni. Chuvangin hei hi practical problem a ni. Experience hian production lama harsatna chinfelna leh efficiency tihsan nan a pui hle. Screw mixing effect a tha bik chuan a chang chuan two-stage screw hrang hrang emaw biaxial screw emaw design a ni a, screw chi hrang hrang section tin chu mixing effect hrang hrang neih theih nan a hranin set a ni.
3. Thi emaw thi emaw lu
Plastic reshaping hi mold emaw die head emaw ah a innghat. Injection molding finished product hi three-dimensional a ni a, mold pawh a complex hle bawk. Shrinkage problem hi ngaihtuah tel a ngai a ni. Thil dang chu plane, strip leh needle continuous product dies te an ni. Special shape an nih chuan special shape-ah an dah a ni. Cooling leh sizing nghal mai chungchanga harsatna awm chu ngaihven tur a ni. Plastic machine tam zawk hi syringe ang maia siam a ni. Screw-in a khalh extrusion force hian outlet tenau takah pressure nasa tak a siam ang a, production efficiency a ti sang ang. Die head hi plane anga design a nih chuan, engtin nge raw materials te chu a chung zawng zawngah inang tlang taka sem darh dan tur, thawmhnaw hanger die head design hi a pawimawh hle. Fish gill pump tihpun nan leh raw materials supply stabilize turin extrusion opportunity ngaihven rawh.
4. A lumna
Sprue gate-a raw materials theh bakah hian injection mold hian cooling channel-a raw materials tihlumna design a nei bawk. Extrusion molding hian roller chhunga cooling water channel a rinchhan a, chu chuan cooling effect a nei thei a ni. Hei bakah hian air knife, cooling water direct-a blowing bag-a drenched, hollow blowing leh cooling method dangte pawh a awm bawk.
5. Extend tur a ni
Finished product reprocessing leh extension hian effect a ti sang zawk ang. Entirnan, hma leh hnung rollers-in packing belt a khalh speed hrang hrang hian extension effect a thlen ang. A siam zawh tawh extension part-a tensile force chu a tichak a, chu chu a hrual awlsam lo a, mahse a dinglam hawia phelh a awlsam hle. Molecular weight distribution hian high-speed production-ah pawh extension effect a nghawng dawn a ni. Extruded product zawng zawng, fiber te pawh hian extension inang lo an nei vek. Vacuum leh compressed air siam hi extension dang anga ngaih theih a ni bawk.
6. Shrink rawh
Raw material eng pawh hian shrinkage problem a nei a, chu chu thermal expansion, cold contraction leh crystallization laia internal stress vang a ni. A tlangpuiin thermal expansion leh cold shrinkage hi hneh a awlsam a, chu chu processing-a cooling time rei zawk leh pressure awm chhunzawm zel hmanga tih theih a ni. Crystalline raw materials hian non crystalline raw materials aiin shrinkage difference a nei lian zawk fo thin a, PP tan chuan 16% vel a ni a, mahse ABS tan chuan 4% vel chauh a ni a, hei hi a danglam hle. He part hi mold-ah hneh a ngai a, a nih loh leh shrinkage rate tihhniamna tur additives dah tel a ni fo a, necking problem tihziaawm nan extrusion plate-ah LDPE dah tel a ni fo bawk.
Plastic thermoforming machine hi thermoplastic zawng zawng deuhthaw ah hman theih a ni. Tun hnaiah plastic thermoforming machine pawh hlawhtling takin thermosetting plastic thenkhat siam nan an hmang bawk. Plastic thermoforming machine-a molding cycle hi a tawi (second tlemte atanga minute engemaw zat) a ni a, a pianzia chu a complex, a size dik tak leh a hun takah mold a siam thei a ni. GTMSMART thermoforming machine siam chhuah zingah hian Plastic hmanga siam Thermoforming Machine hmanga siam a ni, . Cup Thermoforming Machine hmanga siam a ni, . Plastic Vacuum siamna hmanrua, . Plastic Pangpar bawm Thermoforming Machine hmanga siam a ni.
GTMSMART a ni bulk production mamawh awlsam taka phuhruk thei tur first-class machine man tlawm ber pe rawh. Kan thil siam hrang hrangte hi han chhui la, i mamawh ang zela high-performance option tam tak i hmu ang.
