注塑加工的温度控制要点!

在注塑加工的过程中,温度的控制是相当的关键的一个要点,因为温度在模具成型和质量上有着很大的影响。下面小编就以济南注塑加工为例,给大家讲解一下注塑加工的温度控制要点!
In the process of injection moulding, temperature control is a key point, because temperature has a great influence on moulding and quality. The following edition takes Jinan injection molding as an example to explain the key points of temperature control in injection molding.
1、射料缸温度环境
1. The Temperature Environment of the Injection Cylinder
应当注意,熔胶温度是很重要的,而所用的任何射料缸温度都只是指导性的。如果你没有加 工过某一特定塑料的经验,请从低的设定开始。通常 区温度设为低值,可防止塑料 在进料口中过早地熔化和粘连。
It should be noted that the melt temperature is very important and that any injection cylinder temperature used is only instructive. If you have no experience in processing a particular plastic, start with a low setting. Usually the temperature of the first zone is set to a low value, which can prevent the premature melting and adhesion of plastics in the inlet and outlet.
其它区的温度于是逐渐升高直至达到射嘴,为防止滴漏,在 射嘴尖端的温度往往稍低。模具也被加热、冷却,由于许多模具的尺寸关系,模具也被区分 ,但除非有说明,各区应该设定为同一大小的尺寸
The temperature in other areas gradually rises until it reaches the nozzle. In order to prevent dripping, the temperature at the tip of the nozzle is usually slightly lower. Dies are also heated and cooled. Dies are also distinguished due to the size of many dies, but unless specified, each zone should be set to the same size.
2、熔胶温度
2. Melt temperature
可测量射嘴或以空气喷射法量度。利用后者进行测量时,必须小心确保清理热熔塑料时不会 发生意外,因为热熔塑料的高温会烧伤皮肤,甚至腐蚀皮肤。在注塑工场内,烧伤是有意外 。
The nozzle can be measured or measured by air injection method. When measuring with the latter, care must be taken to ensure that no accidents occur when cleaning hot-melt plastics, because the high temperature of hot-melt plastics can burn or even corrode the skin. Burns were accidental in the injection moulding workshop.
因此,在处理热塑料或遇上热熔塑料四溅的危险地,应当戴上手套及面罩。为确保安全, 控热针的尖端应预先加热至要测量的温度。每种塑料均有一个特定的熔胶温度,要达到这个 温度注塑实际射料缸调值还需视乎螺村转动速度、背压、射料量及注塑周期而定。
Therefore, gloves and masks should be worn when dealing with hot plastics or in danger of splashing hot melt plastics. To ensure safety, the tip of the heat control needle should be pre-heated to the temperature to be measured. Each plastic has a specific melt temperature. To achieve this temperature, the actual injection cylinder adjustment depends on the rotating speed, back pressure, injection volume and injection cycle of Luocun.

3、模具温度
3. Die Temperature
要经常检查注塑机是否在记录单上指定的温度下设定和运行。这是非常重要的。因为温度会 影响注塑件表面光洁度和产量。所有测量得出的数值都必须记录下来,并按指定的时间检查 注塑机。
Always check whether the injection machine is set and operated at the temperature specified on the record sheet. This is very important. Because the temperature will affect the surface finish and production of injection parts. All measured values must be recorded and the injection machine checked at the specified time.
4、温度和冷却检查
4. Temperature and Cooling Inspection
