POM

POM yog ib qho muaj zog, nruj engineering yas paub txog nws cov kev hnav zoo heev, tsis muaj kev sib txhuam, thiab qhov zoo ntawm qhov ntev. Nws muaj lub zog txhua yam, zoo tshuaj tiv thaiv, thiab du nto zoo, ua rau nws yog ib qho zoo tagnrho cov khoom siv rau precision qhov chaw xws li lub zog, bearings, structural connectors, automotive Cheebtsam, thiab ntau yam mechanical lossis functional txhaj - molded qhov chaw.

Peb tau tsim POM molded Cheebtsam rau:

Customized POM mechanical qhov chaw rau cov khoom siv thiab cov khoom siv hluav taws xob

2. Daim ntawv thov teb ntawm POM Txhaj Moulding

Mechanical Cheebtsam: Cov yam ntxwv ntawm cov khoom, cov khoom sib txuas ua haujlwm, cov khoom txhawb nqa, thiab cov khoom sib dhos precision siv hauv ntau yam khoom siv

Cov khoom lag luam: Hnav- tiv thaiv zawv zawg Cheebtsam, qis- kev sib txhuam txav, thiab siab- qhov chaw ruaj khov rau cov tshuab

Consumer & Electrical Devices: Functional internal parts, brackets, clips, mounting pieces, and structural Cheebtsam

Automotive & Khoom siv: Cov khoom siv sab hauv ua haujlwm ruaj khov, cov khoom siv kho tshuab, thiab cov khoom siv uas yuav tsum tau muaj zog thiab qhov ruaj khov

3. Yuav ua li cas kom tau ib tug zoo nto tiav rau POM Txhaj Moulded Parts

POM qhov chaw hais txog lub zog txhua yam, qhov tseeb qhov tseeb, thiab kev sib txhuam qis. Txij li thaum POM yog rhiab heev rau thermal degradation thiab shear overheating, ruaj khov thiab tsim pwm tsim yog qhov tseem ceeb kom tsis txhob muaj qhov kub hnyiab, deformation, warpage, los yog tsis zoo nto.

3.1 Pwm Zoo

Kab noj hniav ua kom tiav: Cov kab noj hniav du txo kev sib txhuam thaum lub sij hawm ejection thiab tiv thaiv cov cim rub; polishing txhim kho qhov sib xws.

Kev huv huv: Cov khoom seem yuav ua rau muaj qhov kub hnyiab lossis cov pob dub; nquag pwm tu kom ruaj khov zoo.

Draft lub kaum sab xis: Tsim nyog cov qauv tiv thaiv khawb thiab txo kev ntxhov siab thaum lub sij hawm demolding, tshwj xeeb tshaj yog rau cov tuab lossis tob.

Lub qhov tso pa tawm: qhov cua tsis txaus yuav ua rau muaj qhov kub hnyiab lossis txhaj tshuaj luv luv; optimized vents txhim kho ntws thiab txo shear tshav kub.

Gate & runner tsim: du kev hloov pauv thiab qhov loj me kom txo tau cov cua sov shear, tiv thaiv degradation lossis nto melting kab.

3.2 Moulding Parameters

Kev txhaj tshuaj nrawm: Nruab nrab mus rau kev kub ceev yog ib txwm muaj, tab sis kev kub ceev heev yuav ua rau shear overheating thiab hlawv cov cim.

Lub tshuab cua txias: Uniform txias txo qis qhov sib txawv ntawm qhov sib txawv thiab tiv thaiv kev ua tsov rog hauv cov khoom siv loj.

Tuav siab & sijhawm: Cov chaw tsim nyog txo qhov tsis muaj dab tsi, txo cov cim, thiab deformation hauv load-cov kabmob.

Melt kub: POM muaj qhov ua haujlwm nqaim; kub dhau heev ua rau degradation, tsw, los yog defects nto.

Backpressure: Tsawg backpressure pab kom tsis txhob muaj kev sib tsoo ntau dhau thiab thermal stress.

3.3 Cov khoom siv raw

Granule uniformity: Ua kom ruaj khov yaj ntws thiab ua haujlwm zoo ib yam.

Kev tswj cov dej noo: POM nqus dej tsawg heev tab sis tseem yuav tsum tau ua kom qhuav kom tsis txhob muaj npuas thiab degradation.

Additive & colorant dispersion: Tsis zoo dispersion tej zaum yuav ua rau streaks los yog tsis muaj zog me ntsis nyob rau hauv txhua yam.

Impurities: Txhua yam kab mob tuaj yeem ua rau cov pob dub lossis ua tsis tiav.

Cov ntsiab lus rov ua dua: Ntau dhau regrind txo lub zog, toughness, thiab aging kuj.

4.Best Parameters rau POM Txhaj Moulding

4.1 Cov Khoom Tseem Ceeb

Thermal Sensitivity: POM txheej txheem ntawm approx . 180-220℃; overheating tuaj yeem ua rau thermal degradation, hlawv cov cim, lossis tsw.

Flow Cwj Pwm: POM muaj cov dej ntws zoo tab sis muaj kev cuam tshuam rau shear overheating; nruab nrab txhaj tshuaj ceev thiab siab kom ruaj khov filling yam tsis muaj degradation.

Shrinkage tus nqi: 1.5-2.0% nyob ntawm seb ib feem geometry; tsim pwm tsim thiab niaj hnub phab ntsa thickness txhim kho seem stability.

Tshuab Hom: Ntsia hlau- hom txhaj tshuaj tshuab nrog kev tswj qhov kub thiab txias tiv thaiv thermal degradation thiab xyuas kom muaj kev ua haujlwm zoo ib yam.

Txhaj ntim: Pom zoo 40-60% ntawm lub tshuab muaj peev xwm kom txo tau lub sijhawm nyob thiab thermal stress.

Runner Design:

- Tus khiav tseem ceeb: Tsawg dua lossis sib npaug li 120 mm

- Sub- khiav: 5–12 mm

- Cov neeg ua haujlwm sib tw, sib tw khiav kom txo tau cov cua sov thiab tswj qhov zoo.

Ejection Force: Lub zog nruab nrab pom zoo kom tsis txhob muaj cov cim, deformation, lossis kev ntxhov siab ntawm cov khoom siv.

Ncej -Kev kho mob: POM feem ntau tsis tas yuav tsum tau annealing; Kev txias me ntsis tuaj yeem txhim kho qhov ruaj khov rau qhov tuab lossis qhov tseeb.

4.2 Yam Moulding Parameters

Cov txheej txheem molding rau POM qhov chaw sib txawv nyob ntawm qib (general-lub hom phiaj, ntxiv dag zog, los yog xim), ib feem tuab, thiab yuav tsum tau siv tshuab ua haujlwm. Txij li thaum POM yog rhiab heev rau thermal degradation thiab shear overheating, kev tswj qhov kub thiab txias, kev txhaj tshuaj me me, thiab kev ua kom txias txias yog qhov tseem ceeb kom tsis txhob muaj qhov kub hnyiab, kev ua tsov rog, kev ntxhov siab sab hauv, lossis qhov chaw tsis xws luag.

Cov kev ntsuas no ua raws li cov lus qhia dav dav. Fine- yuav tsum tau kho raws li ib feem geometry, phab ntsa thickness, muab tub lim/reinforcement cov ntsiab lus, khiav tsim, thiab txias layout kom ua tau zoo mechanical zog, seem stability, thiab nto zoo.
