style="text-indent:25px">壓縮成型：俗稱壓制成型，是較早成型塑件的方法之一。壓縮成型是將塑料直接加入到具有一定溫度的敞開的模具型腔內(nèi)，然后閉合模具，在熱與壓力作用下塑料熔融變成流動(dòng)狀態(tài)。由于物理及化學(xué)作用，而使塑料硬化成為具有一定形狀和尺寸的常溫保持不變的塑件。壓縮成型主要是用于成型熱固性塑料，如酚醛模塑粉、脲醛與三聚氰胺甲醛模塑粉、玻璃纖維增強(qiáng)酚醛塑料、環(huán)氧樹脂、DAP樹脂、有機(jī)硅樹脂、聚酰亞胺等的模塑料，還可以成型加工不飽和聚酯料團(tuán)（DMC）、片狀模塑料（SMC）、預(yù)制整體模塑料（BMC）等。一般情況下，常常按壓縮膜上、下模的配合結(jié)構(gòu)，將壓縮模分為溢料式、不溢料式、半溢料式三類。北京模具制造加工廠模具制造鋼淬火前未進(jìn)行正確的球化處理工藝，球化組織不良。</p><div

style="text-indent:25px">提高模具質(zhì)量的基本途徑：模具的設(shè)計(jì)是提高模具質(zhì)量的較重要的一步，需要考慮到比較多因素，包括模具材料的選用，模具結(jié)構(gòu)的可使用性及安全性，模具零件的可加工性及模具維修的方便性，這些在設(shè)計(jì)之初應(yīng)盡量考慮得周全些。模具的制造過程也是確保模具質(zhì)量的重要一環(huán)，模具制造過程中的加工方法和加工精度也會(huì)影響到模具的使用壽命。各零部件的精度直接影響到模具整體裝配情況，除掉設(shè)備自身精度的影響外，則需通過改善零件的加工方法，提高鉗工在模具磨配過程中的技術(shù)水平，來提高模具零件的加工精度。對(duì)模具主要成形零部件進(jìn)行表面強(qiáng)化，以提高模具零件表面耐磨性，從而更好地提高模具質(zhì)量。</p><p style="text-indent:25px">注塑模具依成型特性區(qū)分為熱固性塑膠模具、熱塑性塑膠模具兩種;依成型工藝區(qū)分為傳塑模、吹塑模、鑄塑模、熱成型模、熱壓模(壓塑模)、注射模等，其中熱壓模以溢料方式又可分為溢式、半溢式、不溢式三種，注射模以澆注系統(tǒng)又可分為冷流道模、熱流道模兩種;以按裝卸方式可分為移動(dòng)式、固定式兩種.模具的結(jié)構(gòu)雖然由于塑料品種和性能、塑料制品的形狀和結(jié)構(gòu)以及注射機(jī)的類型等不同而可能千變?nèi)f化，但是基本結(jié)構(gòu)是一致的。模具主要由澆注系統(tǒng)、調(diào)溫系統(tǒng)、成型零件和結(jié)構(gòu)零件組成。其中澆注系統(tǒng)和成型零件是與塑料直接接觸部分，并隨塑料和制品而變化，是塑模中復(fù)雜，變化大，要求加工光潔度和精度高的部分。注塑模具由動(dòng)模和定模兩部分組成，動(dòng)模安裝在注射成型機(jī)的移動(dòng)模板上，定模安裝在注射成型機(jī)的固定模板上。模具制造的好與壞是要有標(biāo)準(zhǔn)：英文字符和數(shù)字應(yīng)大于5/6，并位于水龍頭正下方10毫米處。</p><div
