1、摘要:我國塑料模具增長迅速,比重不斷提高.近年來,我國塑料模具發(fā)展迅速,目前塑料模具在整個模具行業(yè)中所占比重約為30%在模具進(jìn)口中占比重達(dá)50^70%隨著中國機(jī)械,汽車,家電,電子信息和建筑建材等國民經(jīng)濟(jì)支柱產(chǎn)業(yè)快速發(fā)展,這一比例將持續(xù)提高.模具市場的總體趨勢是平穩(wěn)向上的,在未來的模具市場中,塑料模具的發(fā)展速度將高于其他模具,在模具行業(yè)中的比例將逐步提高.二:塑料模具已形成巨大產(chǎn)業(yè)鏈我國塑料模具在高技術(shù)驅(qū)動和應(yīng)用產(chǎn)業(yè)需要的推動下,形成了一個巨大的產(chǎn)業(yè)鏈條,從上游的原輔材料工業(yè)和加工.檢測設(shè)備到下游的機(jī)械.汽車?摩托車.家電?電子通信.建筑建材等
2、幾大應(yīng)用產(chǎn)業(yè),塑料模具發(fā)展一片生機(jī).目前,塑料制品的應(yīng)用日益廣泛,為塑料模具提供了一個廣闊的市場,同時對模具也提出了更高的要求.大型化,高精密度,多功能復(fù)合型的模具將受到青睞.關(guān)鍵詞注塑模具:新型技術(shù)Abstract:A:plasticmoldisgrowingrapidlyinourcountry,theproportionofincreasingInrecentyears,China'splasticmold,plasticmoldinthemoldindustryaccountedforabout30%,inthemoldimported
