The reasons for the shortcomings of plastic ware injection molding:

1. Plastic: Check the grade or type, check for impurities, and confirm whether the snake meets the manufacturer's specifications. If this shortcoming is obvious in several batches of plastic from the same manufacturer or the same plastic from another supplier, it means that there is no problem with the plastic. Observe the effect of recycled materials, and pay special attention to its different processing characteristics from the same new materials.

2. Injection molding machine: Check the functions of all parts of the injection molding machine, and consider any factors that may affect pressure, temperature, ratio and time. If the shortcoming occurs intermittently, this usually implies an error in the operation of the injection molding machine, such as a temperature fluctuation caused by a bad thermocouple. If the defect occurs in the same position as a single-cavity mold, it implies that the cause of the problem lies in the device of the injection cylinder (such as the return valve) or the control adjustment of the in-service injection molding machine.

3. Mold: Make sure that the mold is properly installed, at the correct temperature, and all parts are operating smoothly. If the shortcomings always appear in the same or several cavities of the multi-cavity mold, the shortcomings usually lie in the feed system (ie, the runners or gates of these mold cavities).

4. Processing process: Check whether the pressure, temperature and time are set according to the recommendation of the plastic supplier. If the shortcoming disappears when the mold is used in another injection molding machine, the shortcoming is probably due to the consistency of the processing conditions used and the original machine. If the shortcoming disappears when another person comes to operate the injection molding machine, the shortcoming may be caused by human error. The speed, the management of the injection molding operation and the residence time for opening and closing the safety door should be checked.
