【正文】 shape cycle pleted. Resin or note billet model of the raw material, usually in pills or particle forms are provided. Resin balls into a great leakage at the bottom of the hopper, hopper and cylindrical level material barrel connections. In a nitrogentreated barrel within the screw by motor rotation, raw materials particles will screw thread slot fill. The screw thread depth to one end of the mould has heating decreases, pression plastic. When screw rotation, plastic particles by screw drive advance, and bear melting needed extreme pressure and friction. In the process of melting, during the external nitrogentreated barrel with resistanse wire to assist in heating and temperature control. Through the flow into the mold cavity plastic will solidify, forming an additional framework. This by molten residual material position of the framework and melting resin flows from hopper wushan, it and cavity mould protrusion parallel, But with the direction of vertical shunt presses the tao, used for molten plastic relay to the gate. Gate and runner system can be cut, twisting and reuse, sometimes in line beside. By institutions Some mould are designed to automatically from parts of the form. China plastics processing enterprise star ROM the cloth, throughout the country, the technology of equipment level irregular, most processing enterprises equipment all need technical reformation. In recent years, our country plastic machinery industry technology progress and remarkable, especially injection technology level and foreign famous brand product in the gap considerably reduced and internal control level, product quality and appearance shape, etc are achieved significant change. Choose domesticallymanufactured equipment, with a small investment, also can be produced with an import equipment quality quite products. These for enterprise39。因此，注射裝置必須保證塑料均勻塑化，并有足夠的注射壓力和保壓壓力。 在料筒內(nèi)的螺桿由電機(jī)轉(zhuǎn)動(dòng)，原料顆粒將螺桿的螺紋槽填滿。當(dāng)推桿返回，所有的成型循環(huán)標(biāo)準(zhǔn)都達(dá)到，那么下個(gè)成 型周期可以開(kāi)始。 當(dāng)注射開(kāi)始建立且冷卻時(shí)間結(jié)束，模具打開(kāi)。第一部分是流入部分，它推動(dòng)塑料小球向前運(yùn)動(dòng)并要求料筒溫度高使得塑料小球軟化。冷卻時(shí)間主要取決于零件的壁厚和材料。模具工作要求低速和低氣壓閉合。注塑成型 在注塑成型中，塑料顆?？恐辛牧隙愤M(jìn)入加熱桶。它通常在模具導(dǎo)桿開(kāi)始運(yùn)作前，必須正確設(shè)計(jì)位置以防止意外 損壞 模具。注射產(chǎn)品通常要求快速冷卻。螺紋深
