1. Pay attention to mold temperature
If the lower temperature of the heat-resistant and abrasion-resistant nylon cable ties in the production, the faster the material cooling rate in the mold cavity, so that it can greatly shorten the take-out time of the product and improve the efficiency of the molding operation. However, if the temperature is too low, it will easily cause the appearance of the product to be poor, such as flow marks, weld marks or shrink marks.

2. Pay attention to screw back pressure

It is understood that the screw back pressure can improve the melting and mixing effect of the nylon insert cable ties. At the same time, the screw back pressure can also ensure that the molten material is filled in the front of the screw, which can improve the injection of nylon insert cable ties. However, in production, we should pay attention that the screw back pressure cann't be too high or too low. if too high and too low, it will cause the material to increase in temperature due to the increase of frictional heat and the measurement of the injection volume will be inaccurate.

3. Pay attention to barrel temperature
Usually, if you wants to know the actual temperature of the nylon cable tie injection molding material, you can only use the method of air injection in production, and sets the temperature of the nylon insert cable tie injection plastic cylinder. In general, it should be kept at a certain temperature gradient, and the nozzle from the back to the front of the device should be set to gradually increase its temperature.
