Introduce the test procedure of injection mould processing

In order to reduce the waste of time in mass production, it is necessary to adjust and control the processing conditions in time, find out the suitable temperature and pressure conditions, and formulate a standard test procedure for injection mould processing, which can be used to establish daily working methods.

 

  1. Check whether the plastic material in the barrel is correct or not, and whether it is baked according to the regulations.

 

  1. The cleaning of material pipes should be careful so as not to inject inferior unglued materials or miscellaneous materials into the die, because inferior unglued materials and miscellaneous materials may jam the die. Check whether the temperature of the material pipe and the temperature of the die are suitable for the raw material for processing.

 

  1. Adjust the pressure and ejection, but do not run the edge and some cavity products have not yet solidified, before adjusting the control conditions should be considered, because filling rate slightly changes, may cause filling changes.

 

  1. When the conditions of machines and moulds are stabilized, even medium-sized machines may have to wait more than 30 minutes. This time can be used to view possible problems in finished products.

 

  1. The advance time of the screw should not be shorter than the solidification time of the gate plastic, otherwise the weight of the finished product will be reduced and the performance of the finished product will be impaired. When the die is heated, the screw advance time should be increased to compact the finished product.

 

  1. Reasonably adjust and reduce the total processing cycle.

 

  1. Running the newly adjusted conditions for at least 30 minutes to be stable, and then producing at least a dozen full-model samples continuously, marking the date and quantity on their holders, and placing them separately according to the moulds, in order to test the stability of their actual operation and derive reasonable control tolerances.

 

  1. Measure and record the important dimensions of continuous samples (when the samples are cooled to room temperature).

 

  1. Comparing the sizes of each sample, we should pay attention to:

 

(1) Whether the size of the product is stable or not.

 

(2) Whether there is a trend of increase or decrease in some sizes, indicating that the processing conditions are still changing, such as poor temperature control or oil pressure control.

 

(3) Whether the size change is within the tolerance range.

 

  1. If the size of the finished product does not change and the processing conditions are normal, it is necessary to observe whether the quality of the finished product with each die hole is acceptable and its size can be within the allowable tolerance. Mark the holes measured continuously or more or less than the average value in order to check whether the size of the die is correct.
