PET preform pwm feem ntau yog ua los ntawm siab - lub zog pwm steel los yog siab - cov ntaub ntawv ua tau zoo. Raws li cov khoom siv, lawv tuaj yeem faib raws li hauv qab no:
Siab -Hardness Txias Ua Haujlwm Pwm Hlau
Feem ntau siv rau hauv cov pwm uas yuav tsum tau hnav tsis kam thiab siab precision, xws li H13 thiab 2316 steel. Nws cov yam ntxwv muaj xws li siab hardness thiab zoo hnav tsis kam, tuav ruaj khov kab noj hniav nyob rau hauv lub sij hawm ntev - ntau lawm.
Corrosion{0}}Resistant Stainless Hlau
Xws li S136 thiab 420 stainless hlau, haum rau cov chaw tsim khoom nrog cov kev xav tau siab rau preform nto tiav thiab susceptibility rau acid thiab alkali corrosion. Corrosion-cov hlau tsis muaj zog ua kom lub ntsej muag du thiab txo qhov tsis xws luag hauv qhov preform.
Aluminium Alloy lossis Copper Alloy Auxiliary Materials
Siv nyob rau hauv uas tsis yog -load- cov khoom siv bearing lossis kub khiav tshuab ntawm pwm, muaj cov thermal conductivity thiab machinability, txhim kho pwm txias efficiency thiab ntau lawm ceev.
Kev xaiv cov ntaub ntawv sib txawv yuav tsum muaj kev ntsuam xyuas zoo raws li qhov ntsuas ntau lawm, cov khoom tshwj xeeb, ib puag ncig tsim khoom, thiab hom raw khoom.
