注塑加工本身是非常具有技术性以及实现性的操作,当然在此加工期间会有很多的环节来进行辅助,其中硬化是重要的方面,很多人对此是不了解的,那么注塑加工硬化有着怎样的过程内容呢?
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?
注塑加工优点是生产速度快,效率高,操作可以自动化,颜色品种多,形状可以从简单到复杂,尺寸可以从大到小,且产品尺寸准确,产品更换方便,可成型复杂形状。在一定温度下,将完全熔融的塑料材料通过螺杆搅拌,高压注入模具型腔,冷却固化,得到成型制品。这种方法适用于复杂形状零件的大批量生产,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过程中完成交联反应的过程,硬化速度通常以塑料试样硬化至1mm厚的第二速度表示。该值越小,硬化速度越快。注塑成型的硬化速度与注塑原料的品种、塑件的形状、壁厚、成型温度、是否预热、预压等密切相关,可明显着加快硬化速度。
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,硬化速度还应适合成型方法的要求。例如注塑或注塑成型时,应要求塑化填充时化学反应慢,硬化慢,并保持长期的工作状态,填充型腔后,应在高温高压下迅速硬化。注塑硬化速度慢的塑料会延长成型周期,降低生产率,而硬化速度快的塑料不能成型成杂乱无章的注塑件。因此,在注塑过程中要严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,
济南注塑加工提醒大家,要想在进行注塑加工作业时不受什么影响而导致环节过程中有问题出现的话,加工时的相关步骤要明确,总结而言便是加热、预塑化---合模和锁紧---注射装置前移---注射、保压---卸压---注射装置后退---开模、顶出塑件。
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.
