Plastic Product Manufacturing Txheej txheem

1. Compression molding

Compression molding, tseem hu ua molding, yog ib txoj kev molding nyob rau hauv uas molding compound yog tsim los ntawm pressurization (feem ntau cua sov) nyob rau hauv ib tug kaw pwm kab noj hniav.

2. Lamination molding

Ib txoj hauv kev sib txuas ob lossis ntau txheej ntawm cov khoom qub lossis cov khoom sib txawv rau hauv tag nrho los ntawm kev kub thiab siab, nrog lossis tsis muaj nplaum.

3. Txias nias molding

Txias nias molding tseem hu ua txias nias sintering molding. Qhov txawv ntawm qhov zoo tib yam compression molding yog tias cov khoom yog pressurized thiab molded nyob rau hauv chav tsev kub.

4. Hloov Moulding

Hloov molding yog ib txoj kev molding ntawm thermosetting yas. Thaum lub sij hawm molding, lub molding compound yog rhuab thiab softened nyob rau hauv lub cua sov chamber, thiab ces nias rau hauv lub rhuab pwm kab noj hniav kom solidify thiab tsim.

5. Extrusion

Extrusion molding, tseem hu ua extrusion molding los yog extrusion, yog ib txoj hauv kev uas cov ntaub ntawv txuas ntxiv tsim los ntawm kev tuag hauv lub xeev ntws los ntawm cua sov thiab nias hauv lub extruder.

6. Pultrusion

Pultrusion yog ib txoj hauv kev molding ntawm thermosetting fiber reinforced plastics. Nws yog siv los tsim cov profiles nrog cov duab sib dhos ruaj khov thiab tsis muaj qhov ntev.

7. Txhaj tshuaj molding

Txhaj tshuaj molding (txhaj tshuaj molding) yog ib txoj hauv kev uas cov thermoplastic los yog thermosetting molding tebchaw yog uniformly plasticized nyob rau hauv ib tug rhuab chim chim, thiab ces thawb mus rau hauv kab noj hniav ntawm ib tug kaw pwm los ntawm ib tug plunger los yog txav ntsia hlau.

8. Tshuab molding

Ib txoj hauv kev uas cov parison kub kaw hauv pwm yog tshuab rau hauv cov khoom hollow los ntawm cov pa roj, los yog lub raj parison yog tshuab rau hauv lub raj yeeb yaj kiab yam tsis muaj pwm.

9. Casting

Ib txoj hauv kev txhaj cov kua monomers, resins lossis lawv cov khoom sib tov rau hauv pwm thiab ua rau lawv mus rau hauv cov khoom tsis muaj zog los yog me ntsis pressurizing lawv.

10. Tes tso

Tes nteg-up molding, tseem hu ua phau ntawv pasting molding thiab hu rau molding, yog ib txoj hauv kev ntawm kev tsim cov khoom siv yas ntxiv.

11. Filament winding molding

Nyob rau hauv cov xwm txheej ntawm kev tswj nruj thiab predetermined kab zoo, nruam filaments impregnated nrog resin kua nplaum yog qhov txhab ntawm ib tug tub ntxhais pwm los yog pwm los tsim cov khoom yas reinforced.

12. Calendering

Ib txoj kev tsim nyob rau hauv uas cov thermoplastics tau dhau los ntawm cov xovxwm rhuab yob los ua ib zaj duab xis lossis daim ntawv nyob rau hauv qhov kev txiav txim ntawm extrusion thiab txuas ntxiv.

13. Txheej

Ib txoj hauv kev ntawm txheej txheej nyias ntawm cov yas (piv txwv li, tsawg dua 0.3 hli) ntawm cov ntaub, ntawv, ntawv hlau lossis board hauv cov kua lossis hmoov rau lub hom phiaj ntawm kev tiv thaiv corrosion, rwb thaiv tsev, kho kom zoo nkauj , lwm.

14. Ua npuas ncauj molding

Foam molding yog txheej txheem ntawm kev tsim cov qauv microcellular hauv cov yas. Yuav luag tag nrho cov thermosetting thiab thermoplastic yas tuaj yeem ua rau hauv cov yas foamed, thiab cov khoom siv feem ntau yog polystyrene, polyurethane, polyvinyl chloride, polyethylene, urea formaldehyde, phenolic, thiab lwm yam.

15. Secondary molding

Secondary molding yog ib txoj hauv kev ntawm cov yas molding ua. Ib txoj hauv kev siv cov yas yas los yog parisons ua cov khoom siv raw los ua rau cov khoom ntawm cov khoom uas xav tau los ntawm cua sov thiab sab nraud quab yuam.
