热塑性弹性体材料注射成型中遇到问题的解决方案：
1。粘性现象
与树脂相比，软TPE注射制品的表面粘性更强。这可以通过降低成型温度、低剪切力和用氮气吹扫成型机液压缸内部来实现，以解决产品表面的粘性问题。当成型机暂停时，橡胶会在成型机模腔的熔融腔中停留很长时间，有时会因热老化而变得粘稠。此外，在高温下使用的产品容易产生粘性。因此，有必要合理选择稳定剂和软化剂的类型和用量
2。凹坑，不同颜色在热塑性弹性体注射产品中，凹坑经常出现。对于此类产品，请围绕产品提供模型设计，例如浇口或流道。鉴于模压制品的颜色不均匀，有必要增加螺旋背压，并加强包装时间
3。溢出边缘
有时树脂会从空腔中溢出并产生毛刺。此时，应先减小灌装量，降低保压压力，缩短保压时间，并注意维修

Thermoplastic elastomer TPE Raw Material for Electrical tool insulator

Solutions to problems encountered in injection molding of TPE materials:
1. Sticky phenomenon
Compared with resin, the surface of soft TPE injection products is more sticky. This can be achieved by reducing the molding temperature, low shear and purging the inside of the hydraulic cylinder of the molding machine with nitrogen to solve the stickiness problem on the product surface. When the molding machine is suspended, the rubber remains in the molten cavity in the mold cavity of the molding machine for a long time, and is sometimes made sticky due to heat aging. In addition, products used at high temperatures are prone to stickiness. Therefore, it is necessary to reasonably choose the type and amount of stabilizers and softeners.
2. Concave holes, different colors
In TPE injection products, concave holes often occur. For such products, provide model designs around the product, such as gates or runners. In view of the uneven color of the molded products, it is necessary to increase the spiral back pressure and strengthen the packaging time.
3. Overflow margin
Sometimes the resin will overflow from the cavity and cause burrs. At this time, you should first reduce the filling volume, reduce the holding pressure, shorten the holding time, and pay attention to repair.
