Pali njira zambiri zopangira mapulasitiki, ndipo njira iliyonse ili ndi ubwino ndi zovuta zomwe zimayenera kugwiritsidwa ntchito mwapadera. Tiyeni tione.

(1) Kuumba jekeseni.

Jekeseni akamaumba ndi jekeseni zipangizo mu nkhungu kupanga mbali. Pochita izi, pulasitiki imayikidwa mu hopper, ndiyeno jekeseni wotentha. Zimadutsa m'chipinda chokhala ndi wononga, kufewetsa kukhala madzimadzi. Kumapeto kwa chipinda, ndi kukakamizidwa kuzirala madzimadzi kudzera pulasitiki nozzle, chatsekedwa nkhungu. Pamene pulasitiki kuzirala ndi kulimba, theka-anamaliza mankhwala kuchokera atolankhani.

(2) Pulasitiki Extrusion.

Plastic extrusion ndi njira yopangira zinthu zambiri. Kumene zopangira zimasungunuka kuti zikhale zozungulira. The ndondomeko extrusion zambiri ntchito kupanga monga mafilimu, mosalekeza mapepala, machubu ndi ndodo. Zogulitsa zamakampani a Lida zimagwiritsa ntchito njira yamtunduwu kwambiri. Pulasitiki imayikidwa mu hopper ndikudyetsedwa m'chipinda chotenthetsera, pamapeto pake zinthuzo zimakanikizidwa. Pulasitiki ikachoka pachikombolecho, amaiyika pa lamba wotumizira kuti izizizire. Nthawi zina zowulutsira mpweya zimagwiritsidwa ntchito panthawiyi kuti ziziziritsa.

(3) Thermoforming.

Thermoforming ndi njira yopangira mapepala a thermoplastic muzinthu zosiyanasiyana. Tsambali limakutidwa pa chimango ndikutenthedwa kuti likhale lofewa. Pansi pa mphamvu yakunja, pepalalo limapangidwa pafupi ndi nkhungu kuti lipeze mawonekedwe ofanana ndi nkhungu pamwamba. Pambuyo pozizira ndi kuumba, zimatsirizidwa ndi kuvala.

(4) Kumangirira Kumangirira.

Kupaka compress nthawi zambiri kumagwiritsidwa ntchito popanga mapulasitiki a thermosetting. Pochita izi, zinthuzo zimafinyidwa mu mawonekedwe omwe akufuna. Ufa woumba pulasitiki ndi zinthu zina zimawonjezeredwa kusakaniza kuti apange mikhalidwe yapadera. Chikombolecho chikatsekedwa ndikutenthedwa, zinthuzo zimauma kuti zipange mawonekedwe omwe akufuna. Kutentha, kupanikizika ndi kutalika kwa nthawi yomwe imagwiritsidwa ntchito popanga ndondomekoyi zimadalira zotsatira zomwe mukufuna.

Zomwe zili pamwambazi ndi gawo la kukhazikitsidwa kwa ndondomeko ya pulasitiki. Khalani tcheru kuti mudziwe zambiri.
