Product Description
Txhaj Molding Txheej Txheem
Kev txhaj tshuaj molding yog qhov tseem ceeb ntawm cov txheej txheem cyclic"Heating & Melting → High-Ntxhiab Txhaum rau hauv Pwm → Cooling & Solidification → Pwm Qhib & Part ejection." Nws yog cov txheej txheem tsim khoom tseem ceeb rau huab hwm coj- ua cov khoom siv thermoplastic.
1. Lub voj voog ua tiav (4 Theem)
Clamping
Lub txav platen kaw thiab kaw cov pwm ib nrab kom tiv thaiv kev txhaj tshuaj tom ntej thiab tiv thaiv pwm flash (pwm sib cais).
Txhaj & Tuav Siab (Packing)
Cov ntsia hlau tig mus rau cov khoom siv yas, thawb pellets rau pem hauv ntej kom tsim yaj nyob rau hauv pem hauv ntej ntawm lub thoob.
Cov ntsia hlau ua raws li lub piston, txhaj cov yaj mus rau hauv pwm kab noj hniav ntawmkev kub siab thiab kev kub ceev.
Tom qab cov kab noj hniav puv lawm, nws hloov mus rautuav lub siablos them rau cov khoom shrinkage thaum txias.
Txias
Cov dej txias ntws los ntawm cov pwm kom txo qis qhov kub kom txog thaum nws ncav cuag lub xeev nruj txaus rau ejection. Thaum lub sijhawm no, cov ntsia hlau ib txhij ua plasticizing rau lub voj voog tom ntej (kev ua haujlwm sib luag).
Pwm Qhib & Ejection
Cov pwm qhib, thiab ejector pins / mechanisms thawb qhov ua tiav tawm, pib lub voj voog tom ntej.
2. Plasticizing Principple (Inside lub chim)
|
Barrel Zone |
Muaj nuj nqi |
|---|---|
|
Pub Zone |
Cov khoom pellets raug xa mus rau pem hauv ntej thaum nqus cov cua sov pib. |
|
Compression Zone (Kev hloov pauv) |
Cov ntsia hlau channel qhov tob txo qis; cov khoom melts vim shear tshav kub thiab sab nraud chim cua sov. |
|
Kev ntsuas Zone |
Lub yaj yog homogenized thiab metered rau hauv lub reservoir nyob rau hauv pem hauv ntej ntawm lub thoob. |
💡 Nco tseg:Yas melting yog ua tiav los ntawm kev sib xyaw ua kesab nraud heater bandsthiabshear kev sib txhuam kubtsim los ntawm rotating ntsia hlau.
3. Filling and forming Principles (Inside the Pwm)
Filling Theem:Melt overcomes tiv thaiv los ntawm cov neeg khiav / rooj vag los sau cov kab noj hniav nyob rau hauv siab. Tsom ntsoov rauflow pem hauv ntej nce, shear rate, thiab weld kab qhov chaw.
Kev tuav theem:Raws li cov polymer cools, nws ntim shrinks. Tuav siab them nyiaj los ntawm kev yuam cov khoom siv ntxiv rau hauv kab noj hniav, txo cov cim dab dej thiab qhov sib txawv ntawm qhov sib txawv.
Txias & Solidification:Cov pwm kub qis dua ua kom txias tab sis ua rau muaj kev ntxhov siab sab hauv / warpage txaus ntshai. Cov pwm kub kub tuaj yeem txhim kho qhov gloss tab sis ncua sij hawm lub voj voog.
Kev tshem tawm: Cov kaum sab xis thiab cov yam ntxwv tsis zoo txiav txim siab seb sab -kev ua (sliders/lifters) yuav tsum tau ua rau demolding.
4. Cov txheej txheem tseem ceeb (Core rau kev teeb tsa)
|
Parameter |
Kev npam |
|---|---|
|
Txhaj Siab / Ceev |
Ua kom tiav, txhaj tshuaj luv luv, flash, weld kab zog. |
|
Tuav Siab & Sijhawm |
Kev them nyiaj yug; cuam tshuam cov cim dab dej, qhov hnyav, thiab qhov ntev. |
|
Barrel Temperature (Zones) |
Plasticizing zoo. Tsawg dhau=unmelted; Siab dhau=degradation/discoloration. |
|
Pwm Kub |
Nto tiav, crystallinity (tseem ceeb rau PA / POM), thiab warpage. |
|
Lub sijhawm txias |
Txiav txim lub sij hawm voj voog; yuav tsum xyuas kom meej tsis muaj deformation thaum ejection. |
|
Back Pressure & Ntsia Hlau RPM |
Muaj feem xyuam rau kev sib xyaw ua ke, splay marks (silver streaks), thiab kev pheej hmoo degradation. |
5. Tej yam tsis xws luag & kev soj ntsuam hauv paus
Short Shot:Tsis txaus siab / ceev, lub rooj vag me me, los yog tsis tshua muaj melt kub.
Flash:Tsis txaus clamping quab yuam, kev txhaj tshuaj ntau dhau, lossis pwm tsis zoo ntawm cov kab sib dhos haum.
Sink Marks:Tsis txaus tuav lub siab los yog lub sij hawm, tsis sib xws phab ntsa thickness.
Warpage:Cov cua txias tsis sib xws, asymmetric molecular orientation, lossis ejection ntxov ntxov.
Voids / Burn Marks:Cov cua tsis zoo, noo noo hauv cov khoom siv raw, lossis cua ntxiab ua rau thermal decomposition.
