注塑加工本身是非常具有技術(shù)性以及實(shí)現(xiàn)性的操作，當(dāng)然在此加工期間會(huì)有很多的環(huán)節(jié)來(lái)進(jìn)行輔助，其中硬化是重要的方面，很多人對(duì)此是不了解的，那么注塑加工硬化有著怎樣的過(guò)程內(nèi)容呢？
Injection molding itself is very technical and implementation of the operation, of course, there will be a lot of links to assist during this processing, hardening is an important aspect, many people do not understand this, so what kind of process of injection molding hardening?
注塑加工優(yōu)點(diǎn)是生產(chǎn)速度快，效率高，操作可以自動(dòng)化，顏色品種多，形狀可以從簡(jiǎn)單到復(fù)雜，尺寸可以從大到小，且產(chǎn)品尺寸準(zhǔn)確，產(chǎn)品更換方便，可成型復(fù)雜形狀。在一定溫度下，將完全熔融的塑料材料通過(guò)螺桿攪拌，高壓注入模具型腔，冷卻固化，得到成型制品。這種方法適用于復(fù)雜形狀零件的大批量生產(chǎn)，是重要的加工方法之一。
Injection molding processing advantages are fast production speed, high efficiency, operation can be automated, color variety, shape can be from simple to complex, size can be from large to small, and product size is accurate, product replacement is convenient, can be shaped complex shape. At a certain temperature, the completely molten plastic material is stirred by the screw, and injected into the mold cavity under high pressure, cooled and solidified, and molded products are obtained. This method is suitable for mass production of complex shape parts and is one of the important processing methods.
注塑加工硬化是指在塑料成型過(guò)程中完成交聯(lián)反應(yīng)的過(guò)程,硬化速度通常以塑料試樣硬化至1mm厚的第二速度表示。該值越小，硬化速度越快。注塑成型的硬化速度與注塑原料的品種、塑件的形狀、壁厚、成型溫度、是否預(yù)熱、預(yù)壓等密切相關(guān)，可明顯著加快硬化速度。
Injection molding hardening refers to the process of completing the crosslinking reaction in the process of plastic forming. The hardening speed is usually expressed by the second speed of plastic specimen hardening to 1mm thick. The smaller the value, the faster the hardening. The hardening speed of injection molding is closely related to the variety of injection molding raw materials, the shape of plastic parts, wall thickness, forming temperature, whether preheating, prepressing and so on, which can obviously accelerate the hardening speed.
此外，硬化速度還應(yīng)適合成型方法的要求。例如注塑或注塑成型時(shí)，應(yīng)要求塑化填充時(shí)化學(xué)反應(yīng)慢，硬化慢，并保持長(zhǎng)期的工作狀態(tài)，填充型腔后，應(yīng)在高溫高壓下迅速硬化。注塑硬化速度慢的塑料會(huì)延長(zhǎng)成型周期，降低生產(chǎn)率，而硬化速度快的塑料不能成型成雜亂無(wú)章的注塑件。因此，在注塑過(guò)程中要嚴(yán)格控制注塑加工硬化的速度。
In addition, the hardening rate should also be suitable for the requirements of the molding method. For example, injection molding or injection molding, should be required when plasticizing filling chemical reaction is slow, slow hardening, and maintain a long-term working state, filling cavity, should be rapidly hardening under high temperature and high pressure. Injection molding hardening slow plastic can prolong molding cycle, reduce productivity, and hardening speed fast plastic cannot be formed into desultorily injection molding. Therefore, in the process of injection molding to strictly control the speed of injection molding hardening.
再者，
濟(jì)南注塑加工提醒大家，要想在進(jìn)行注塑加工作業(yè)時(shí)不受什么影響而導(dǎo)致環(huán)節(jié)過(guò)程中有問(wèn)題出現(xiàn)的話，加工時(shí)的相關(guān)步驟要明確，總結(jié)而言便是加熱、預(yù)塑化---合模和鎖緊---注射裝置前移---注射、保壓---卸壓---注射裝置后退---開(kāi)模、頂出塑件。
Moreover, Ji 'nan injection molding reminds you that if you want to be free from any influence in the process of injection molding, there are problems in the process of processing, the relevant steps should be clear, To sum up, it is heating, preplasticizing, mold closing and locking, injection device moving forward, injection, pressure holding, pressure relief, injection device backward, mold opening and plastic ejection.
