Lub hauv paus ntsiab lus ntawm siab -gloss, seamless txhaj molding tshuab

High-gloss, cim- pub dawb txhaj tshuaj molding (hloov kub lub voj voog molding, RHCM), tseem hu ua cua kub ceev thiab txiastxhaj tshuaj molding, hloov pauv kub txhaj tshuaj molding, los yog siab -gloss xim- pub dawb txhaj tshuaj molding (hu ua siab -gloss, cim- pub dawb txhaj tshuaj molding hauv phau ntawv no), yog ib txoj kev uas siv high- kub superheated dej (steam) kom sov cov pwm thiab qis - pwm txias. Cov pwm saum npoo yog rhuab mus rau saum lub iav hloov kub ntawm cov yas siv 180℃superheated dej (steam), thiab tom qab ntawd cov yas molten yog sai sai txhaj rau hauv pwm kab noj hniav.

 

Tom qab cov pwm kab noj hniav puv lawm, dej txias yog tam sim ntawd siv los ua qhov nruab nrab txias kom txias cov pwm, ua rau qhov kub thiab txias ntawm pwm, yog li hloov cov yam ntxwv saum npoo ntawm cov yas thiab ua rau cov khoom yas nrog cov khoom zoo heev. Cov txheej txheem ntws ntawm siab -gloss, cim- pub dawb txhaj tshuaj molding yog qhia hauv daim duab.

High-gloss, seamless txhaj molded yas qhov chaw feem ntau yog "xim-dawb." "Paint-dawb" txhais tau hais tias cov khoom yas tsis tas yuav tsum tau pleev xim tom qab molding; ib qho kev txhaj tshuaj molding txheej txheem ncaj qha ua tiav qhov "glossy" zoo li xav tau rau cov xim pleev xim. Qhov no yog ib qho kev phooj ywg zoo ib puag ncig, tsis tshua muaj -VOC (volatile organic compounds) cov khoom, thiab yog li ntawd dav siv nyob rau hauv cov khoom xws li cua txias casings, TV decorations, tub yees, tsheb grilles, thiab automotive sab hauv thiab sab nrauv trim.

Kev xaiv hlau rau siab -gloss, seamless txhaj pwm

Cov yam tseem ceeb uas cuam tshuam rau siab -gloss, blemish-pwm pub dawb suav nrog kev xaiv thiab ua cov ntaub ntawv pwm, tsim pwm cov cua txias, thiab tswj qhov kub thiab txias. Ntawm cov no, kev xaiv cov khoom siv pwm yog ib feem tseem ceeb ntawm kev ua tiav cov txheej txheem cua sov thiab cua txias sai. High-gloss, blemish- pub dawb txhaj pwm muaj cov cai hauv qab no rau cov hlau:

Yog li ntawd, siab -gloss, seamless txhaj pwm yuav tsum tau pwm steel nrog siab toughness, corrosion kuj, thermal qaug zog tsis kam, zoo thermal conductivity, thiab ib tug haum coefficient ntawm thermal expansion.
Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm siab -gloss, seamless txhaj pwm steel, peb kuj tau sau cov kev paub ntawm ntau tus kws tshaj lij, uas tau nthuav tawm hauv qab no.

S136 pwm steel los ntawm ASSAB (Swedish Steel)

Qib no ntawm cov pwm hlau yog ua kom zoo los ntawm txoj kev electroslag remelting (ESR), uas ua rau muaj qhov ntshiab thiab zoo microstructure. Nws muaj cov zoo corrosion kuj, zoo heev polishability, zoo heev hnav tsis kam, zoo heev hardenability, thiab zoo heev toughness thiab ductility. Qhov loj feem ntawm cov khoom nyob rau qib no ntawm cov pwm hlau yog: C (0.38%), Si (0.8%), Mn (0.5%), Cr (13.6%), P (<0.03%), S (<0.03%), etc. Its high chromium content gives it stainless steel characteristics, making it a corrosion-resistant mirror mold steel. It can be used in high-gloss, mark-free injection molds, components for high-demand food industry machinery, and for molding plastics such as PVC, PP, and PE. The mold cooling channels do not corrode as easily as those of ordinary mold steel; its heat conduction characteristics and cooling efficiency remain stable throughout the mold's lifespan, ensuring consistent performance over time.

NAK80, siab- daim iav- tiav yas pwm steel los ntawm Daido Steel Co., Ltd. ntawm Nyiv.

Lub npe NAK yog los ntawm kev sib ntxiv ntawm npib tsib xee (Ni), txhuas (Al), thiab tooj liab (Cu, los ntawm German lo lus Kupfer) mus rau hlau. Thawj tsab ntawv ntawm peb lub ntsiab lus alloying tau ua ke los ua "NAK." Txij li thaum NAK80 tau tsim nyob rau xyoo 1980, nws tau hu ua "NAK80" tom qab nws xyoo ntawm keeb kwm. Tau plaub caug xyoo, qib steel no yog qhov zoo tshaj plaws - muag khoom hauv kev lag luam. Cov feem ntau ntawm cov khoom hauv NAK80 steel yog: C (0.15%), Ni (3.0%), Al (1.00%), Cu (1.00%), Si (0.30%), Mn (1.50%), Mo (0.30%), thiab Cr (0.30%). NAK80 steel muaj daim iav zoo heev- ua tiav machinability (yooj yim sib tsoo thiab polishing), yog ua ntej- tawv (tsis muaj kev kho cua sov), muaj kev hnav tsis kam (siab hardness), zoo machinability (yooj yim txiav), zoo weldability, thiab yog haum rau zoo nkauj tsim (yooj yim etching). Nws tau tas li yog ib qho ntawm cov hlau pwm nyiam rau siab -gloss, seamless txhaj molding.

Nyob rau hauv xyoo tas los no, Nyiv Daido Steel Co., Ltd. tau tsim PAT868S, tshwj xeeb siab-kev ua tau zoo yas pwm hlau. Cov ntsiab lus tseem ceeb tau khaws cia tsis pub lwm tus paub, tab sis nws yog ib qho kev txhim kho ntawm thawj SKD61. Los ntawm kev smelting tshwj xeeb, nws muab cov txiaj ntsig zoo ntawm 42 hom stainless hlau thiab H13 kub- ua haujlwm hlau, thaum tseem muaj cov tawv tawv thiab cov iav polishing zoo heev, ua tiav daim iav tiav txog li 10000 grit (# 10000). Nws yog xeb-resistant thiab yooj yim los tswj; nws muaj qhov toughness tib yam li SKD61, tiv thaiv kev tawg; thiab piv rau PAT868, nws ua tiav qhov hardness siab dua (53 HRC), nrog rau cov khoom hardness tsawg dua los yog sib npaug rau 229 HB, thiab zoo dua hnav tsis kam thiab hardenability. Yog li ntawd, PAT868S yog haum rau ntev- lub sij hawm ntau lawm ntawm complex lug thiab siab - nto- tiav yas txhaj pwm, puab pwm qhov chaw, inserts, angled ejector pins, thiab zawv zawg mechanisms (sab core rub mechanisms), as well as high-gloss, cim-cov pwm pub dawb thiab cov pwm hluav taws xob cua sov.
