style="text-indent:25px">模具材料與表面處理技術(shù)將受到重用：模具材料的質(zhì)量和性能是影響模具質(zhì)量、壽命和成本的重要因素。近年來(lái)，除了不斷有多種高韌性和高耐磨性冷作模具鋼、火焰淬火冷作模具鋼、粉末冶金冷作模具鋼推出外，國(guó)外在大中型沖壓模具上選用鑄鐵材料，是一個(gè)值得關(guān)注的發(fā)展趨勢(shì)。球墨鑄鐵具有良好的強(qiáng)韌性和耐磨性，其焊接性能、可加工性、表面淬火性能也都較好，而且成本比合金鑄鐵低，因此在汽車沖壓模具中應(yīng)用較多。管理的科學(xué)化與信息化是模具企業(yè)發(fā)展方向：汽車模具技術(shù)發(fā)展的另一個(gè)重要方面是管理的科學(xué)化與信息化。管理的科學(xué)化使模具企業(yè)不斷地向準(zhǔn)時(shí)制造和精益生產(chǎn)的方向發(fā)展，企業(yè)管理更加精確，生產(chǎn)效率大幅提高，無(wú)效的機(jī)構(gòu)、環(huán)節(jié)和人員不斷精簡(jiǎn)。隨著現(xiàn)代管理技術(shù)的進(jìn)步，許多先進(jìn)的信息化的管理工具，包括企業(yè)資源管理系統(tǒng)（ERP）、客戶關(guān)系管理（CRM）、供應(yīng)鏈管理（SCM）、項(xiàng)目管理（PM）等，在模具企業(yè)得到普遍應(yīng)用。金華汽車模具技術(shù)有限公司根據(jù)輪胎模具圖鑄造或鍛打毛坯，再粗車毛坯并熱處理。</p><div

style="text-indent:25px">汽車注射模注射模又稱注塑模。這種模具的成型工藝特點(diǎn)是，將塑原材料放置在注射機(jī)的加熱料筒內(nèi)。塑料受熱熔融，在注射機(jī)的螺桿或柱塞推動(dòng)下，經(jīng)噴嘴和模具的澆注系統(tǒng)進(jìn)入模具型腔，塑料在模具型腔內(nèi)經(jīng)保溫、保壓、冷卻固化成型。由于加熱加壓裝置能夠分階段發(fā)揮作用，注射成型不但能成型形狀復(fù)雜的塑料制件，而且生產(chǎn)效率高、質(zhì)量好。故注射成型在塑料制件成型中占有很大的比重，注射模占塑料成型模具的一半以上。注射機(jī)主要用于熱塑性塑料的成型，近年來(lái)也逐漸用于熱固性塑料的成型。</p><p style="text-indent:25px">汽車模具材料的使用性能：(1)沖裁模材料的使用要求，對(duì)于薄板沖裁模具的用材要求具有高的耐磨性和硬度，而對(duì)厚板沖裁模除了要求具有高的耐磨性、抗壓屈服點(diǎn)外，為防止模具斷裂或崩刃，還應(yīng)具有高的斷裂抗力、韌性；(2)拉延、整形模材料的使用要求，要求模具工作零件材料具有高的耐磨性和硬度、一定的強(qiáng)韌性以及較好的切削加工性能、良好的抗粘附性(抗咬合性)，而且熱處理時(shí)變形要小。根據(jù)汽車廠生產(chǎn)沖壓件的模具現(xiàn)狀，汽車模具主要采用的材料為：鉬鉻鑄鐵、Cr12MoV、鑄態(tài)空冷鋼。力求孔徑規(guī)范化，降低汽車模具的制造和維修保養(yǎng)費(fèi)用。</p><div

style="text-indent:25px">車身標(biāo)志了那款汽車的形象特征。汽車模具從狹近年來(lái)，我國(guó)汽車工業(yè)的快速發(fā)展極大地帶動(dòng)了汽車模具行業(yè)的發(fā)展。目前.國(guó)內(nèi)模具骨干企業(yè)由于技改投入大、起點(diǎn)高，正在向規(guī)模化、高水平方向發(fā)展;而民營(yíng)模具企業(yè)則異軍突起，發(fā)展迅猛。模具是技術(shù)型產(chǎn)品和典型的非定型產(chǎn)品.尤其是汽車覆蓋件模具的技術(shù)含量非常高。模具制造企業(yè)是典型的單件生產(chǎn)制造企業(yè)，每套模具都要進(jìn)行創(chuàng)造性的設(shè)計(jì)、數(shù)控編程、生產(chǎn)準(zhǔn)備、機(jī)械加工、裝配及試沖，增加了企業(yè)生產(chǎn)管理的復(fù)雜性和難度。如何提高生產(chǎn)效率、縮短開發(fā)周期、提高模具技術(shù)水平、降低生產(chǎn)成本一直是模具企業(yè)面臨的難題。北汽福田濰坊模具廠經(jīng)過(guò)多年的實(shí)踐和探索，進(jìn)行的全過(guò)程實(shí)施并行工程、標(biāo)準(zhǔn)化設(shè)計(jì)與制造、精細(xì)化加工一次到位、專業(yè)化協(xié)作生產(chǎn)和粗精加工分開進(jìn)行等生產(chǎn)組織方式也同樣適合于我國(guó)的中小模具制造企業(yè)。迅猛發(fā)展的中國(guó)汽車工業(yè)為國(guó)內(nèi)的汽車模具帶來(lái)了廣闊的發(fā)展空間。江陰汽車模具加工公司</p><p style="text-indent:25px">轎車覆蓋件模具設(shè)計(jì)制造具有難度大、質(zhì)量和精度要求高的特點(diǎn)，是汽車模具水平的比較好體現(xiàn)。金華汽車模具技術(shù)有限公司</p><p style="text-indent:25px">現(xiàn)在大量采用的以IF鋼為主的軟鋼系列將被**度鋼板系列替代，**度低合金鋼將被雙相鋼和超**度鋼板替代。目前，國(guó)內(nèi)汽車零件**度鋼板的應(yīng)用還多限于結(jié)構(gòu)件與梁類件，所用材料的抗拉強(qiáng)度多在500MPa以下。因此，迅速掌握**度鋼板沖壓技術(shù)，是我國(guó)汽車模具行業(yè)亟待解決的一個(gè)重要問(wèn)題。隨著汽車沖壓生產(chǎn)高效化和自動(dòng)化的發(fā)展，級(jí)進(jìn)模在汽車沖壓件的生產(chǎn)中應(yīng)用將更加普遍。級(jí)進(jìn)模是一種高新技術(shù)模具產(chǎn)品，技術(shù)難度大，制造精度要求高，生產(chǎn)周期長(zhǎng)，多工位級(jí)進(jìn)模將是我國(guó)重點(diǎn)發(fā)展的模具產(chǎn)品之一，形狀復(fù)雜的沖壓件，特別是一些按傳統(tǒng)工藝需要多副沖模分序沖制的中小型復(fù)雜沖壓件，越來(lái)越多地采用級(jí)進(jìn)模成形。金華汽車模具技術(shù)有限公司</p></p><br
