如何挑选二手大型注塑机,要注意些什么?
心明眼亮才不上当,不然会很惨的

1、注射系统,它在立式注塑机中的作用就是进行很好的主色,能够在规定的时间范围内将一定数量的塑料加热之后,在对它实施一定的压力,则它就能够很好的将熔融好的塑料射到模具型体中。
2、合模系统,它在立式注塑机中的作用就是能够很好的确保模具具有闭合和开启再顶出制成好的模具,在制作模具时它能够预防模具在制作时有裂缝的现象。
3、液压系统,它在生产模具的功能就是能够很好的为立式注塑机提供一定的压力,速度,温度等能够满足注射机注射提供动力。
4、电气控制系统 ,它就是要给注射机提供相关注射的要求,像压力,温度,时间等等。
5、加热/冷却系统,在对模具生产的时候,会对温度有一定的要求才能够更好的达成模具的生产要求,所以加热/冷却系统很好的提供了这样的温度。
6、润滑系统,为了提高注塑机的使用寿命,减少各个零件之间的摩擦,所以在注塑机上就会安装相关的润滑系统。
7、安全保护与监测系统,能够确保注塑机在运行中的安全的生产,能够很好的保护人和机器的安全的装置。
二手大型注塑机的选购,首先需要考虑自身的资金问题进行选择,选择正规的官网(如果可以实地进行查看)或线下二手市场,询问清楚产品是否有质量和售后服务的保证,查看产品的生产日期、出厂证明、油路系统等各个零件选择注塑机的品牌也很重要,国内有很多知名的品牌:海天、震雄、佳明、力劲、伊之密等,了解各品牌产品的相关性能、突出点、生产能力等,选择合适自己的品牌的产品才才是正确的。
重点检查 格林柱 看是新试的还是老试的 注塑机 我们公司是生产注塑级的 经常有 10年左右的老机子拉回来修理 经常把固定板拆开
里面有格林柱断裂的 还有就是检查 调模丝母齿轮完好吗?
油缸压力是否足够 漏油吗? 最重要的是最后检查移动板是否完好 检查 合磨间隙多少。

祝你好运
这是很专业的问题,LZ应该要加分的!
大型注塑机应该检查油泵性能、模板平衡度、控制系统、油路、螺杆材质、、、、、、
