Plastic thilri hna caah sersiam ningcang hna cu zeidah an si?

Plastic thilri hna caah a sining suaisamnak ah hin a tlangpi in a sining, a tahfung a dikthliar, suaimi zat, a cunglei a rawkmi, vampang a thuhnak, a tliknak tlukruannak, a kuang kauhnak, fillet radii, tthencheunak tlukruannak le thazaang peknak ruh hna tibantuk ruahnak aa tel. Hi capar nih hin hi thil pakhat cio hi a fianter lai i thilri tthatnak le chuah khawhnak tthatnak caah thermoforming tuah lio ah hi thilri pawl hi zeitindah ttha tein hman khawh a si timi kong a ceih lai.

1. Geometry le Dimensional A dikthliar

Lio in plastic lumternak cu a pahnihnak thil sernak lam a si, a hlei in vacuum sernak ah, plastic catlap le cawhnuk karlak ah tthennak a um tawn. Cun, a tlawm deuhmi le aa thlengmi, a hlei in a chuakmi hmun hna ah, vampang a thuhnak kha a tlawmter khawh, cu nih cun a thazaang a zorter khawh. Cucaah, vacuum sernak ah hmanmi plastic thilri hna cu geometry le dimensional a dikthliarnak caah a fek tukmi phunglam an ngeih awk a si lo.

Sernak tuah lio ah, a lummi plastic catlap cu a tthawng lomi dirhmun ah a um, cu nih cun a ttumter khawh. Demolding tuah hnu ah a lin tukmi le a tlawm deuhmi he fonh ahcun, thilri a donghnak a kauhning le a muisam cu lum le kih le pawngkam thlennak ruangah a fek kho lo. Hi ruang ah, thermoformed plastic tthen pawl cu a dikthliar in sernak hmannak caah aa tlak lo.

2. Draw Ratio

Draw ratio, cu cu thilri pakhat a sannak (asiloah a thuhnak) le a kauhnak (asiloah a kauhning) karlak i ratio a si, nih hin sernak riantuannak a harnak kha a khiah. Draw ratio a ngan deuhdeuh ahcun, sersiam ningcang cu a har deuhdeuh, cun a ttha lomi thil a chuah khawhnak a tam deuhdeuh, cu hna cu a tlongmi asiloah a thlehmi an si. A hlei in hnuh zat nih thilri thazaang le a fekmi kha a zorter ngaingai. Cucaah, chuah taktak ahcun, a tam bik laknak ratio tang ah a ummi kha hman a si tawn, a tlangpi in 0.5 le 1 karlak ah a si tawn.

Draw ratio cu a tlawmbik vampang a thuhnak he direct in aa pehtlai. A hme deuhmi suai ratio nih a thuk deuhmi vampang a ser khawh, a tlawmmi cahnah sernak caah aa tlak, cu lioah a ngan deuhmi draw ratio nih vampang a tlawm tuk lo nakhnga a chak deuhmi catlap a herh. Cun, hnuh zat cu mold hnuh tlukruannak le plastic thilri a tthawng khawhnak he zong aa pehtlai. Thilri tthatnak hngalh khawhnak ding caah, thilri hlonhmi zat karhternak hrial khawhnak ding caah lakmi zat kha uk a hau.

3. Fillet Design

Plastic thilri hna i an kam le an kam ah a tlikmi kam hna cu suai ding a si lo. Cu nakin, a ngan khawh chungin fillet hman ding a si, a kam radius cu a tlangpi in catlap a thuhnak let 4 in let 5 nak tlawm deuh lo ding a si. Cutin tuah lo ahcun thilri a tlawmter khawh i hnahnawhnak a chuahter khawh, cu nih cun thilri thazaang le a hmunh khawhnak kha a chiatnak lei in a hnorsuan khawh.

4. Draft Angle

Thermoforming mold, a tlangpi mold he aa lo mi hna nih, demolding tuah khawhnak ding caah draft angle pakhatkhat an herh. Draft angle cu a tlangpi in 1° in 4° karlak a si. Nu mold caah a hme deuhmi draft angle hman khawh a si, zeicahtiah plastic tthen a tlawm deuhnak nih a dang tlawmpal a pek, cu nih cun demolding a fawiter.

5. Thazaang Peknak Rib Design

Thermoformed plastic sheets cu a tlangpi in a tlawm ngai, cun sernak kalning cu a hnuhmi zat nih a kham. Cucaah, a derthawmmi hmun ah thazaang peknak ruh pawl chap cu a fekmi le a fekmi karhternak caah a herhmi lam pakhat a si. A tanglei le a kam ah a tlawm tukmi hmun hrial khawhnak ding caah thazaang peknak ruh chiahnak kha ralring tein ruah a hau.

Cun, thermoformed shell tang ah a thuk lomi hliahcang, hmanthlak, asiloah hmelchunhnak pawl chapnak nih a fekmi a ṭhanchoter khawh i a sining kha a dirpi khawh. A kam ah a saumi a thukmi hliahcang nih a dirnak a fekmi a karhter, cu lioah a tlarimi a thukmi hliahcang nih cun, a rawhnak doh khawhnak a ṭhanchoter ko nain, hrawhnak kha a harter deuh.

6. Thilri tlawmternak

Thermoformed thilri a tlangpi in a tlawm deuhmi an ton, 50% hrawng cu mold chung i a lum lio ah a cang. Mold lumnak a sang ahcun, a cheu cu demold tuah hnu ah room lumnak tiang a kik tikah 25% in a zor kho, a tangmi 25% cu a ra laimi suimilam 24 chungah a zor lai. Cun, nu mold hmangin sermi thilri hna cu pa mold hmangin sermi nakin 25% in 50% tiang a tlawm deuhmi an ngei tawn. Cucaah, a donghnak tahfung nih a dikthliar in a herhmi a tlinh khawh nakhnga suaisamnak tuah lio ah tlawmternak kha ruah a biapi.

Geometry, draw ratio, fillet radius, draft angle, reinforcement ribs, le shrinkage caah suaisamnak kha ttha tein sernak thawngin, thermoformed plastic thilri hna i an tthatnak le an fekmi kha tampi in tthanchoter khawh a si. Hi thil kalning suaisamnak thilri hna nih hin thermoformed thilri chuah khawhnak le riantuan ning ah a biapi tukmi thlennak an ngei i thilri nih hmantu herhmi a tlinh khawhnak hnga a biapi tukmi an si.
