塑料及塑料工業(yè)的發(fā)展情況中國(guó)塑料模具發(fā)展速度相當(dāng)快。目前我國(guó)塑料模具在整個(gè)模具行業(yè)中所占比重約為 30%。隨著中國(guó)汽車、家電、電子通訊、各種迅速發(fā)展，預(yù)計(jì)在未來(lái)模具市場(chǎng)中，塑料模具占模具總量的比例仍將逐步提高，且發(fā)展速度將快于其他模具,塑料的應(yīng)用將面對(duì)汽車工業(yè)航空航天工業(yè)、電子電氣工業(yè)、包裝工業(yè)、建材工業(yè)、農(nóng)業(yè)等諸多領(lǐng)域。 選題的依據(jù)和背景我之所以選擇關(guān)于注塑成型的課題是因?yàn)榻陙?lái)，中國(guó)塑料模具發(fā)展速度相當(dāng)快。目前我國(guó)塑料模具在整個(gè)模具行業(yè)中所占比重約為30%。隨著中國(guó)汽車、家電、電子通訊、各種迅速發(fā)展，預(yù)計(jì)在未來(lái)模具市場(chǎng)中，塑料模具占模具總量的比例仍將逐步提高，且發(fā)展速度將快于其他模具。 模具工業(yè)作為進(jìn)入小康社會(huì)的原動(dòng)力之一,正推動(dòng)著整個(gè)工業(yè)技術(shù)的發(fā)展和進(jìn)步。當(dāng)今社會(huì)，模具就是現(xiàn)代化，模具就是高效益的觀念，已被越來(lái)越多的人所接受。塑件質(zhì)量的優(yōu)劣及生產(chǎn)效率的高低，模具因素占
