The main steps of car exterior and interior trim moulds trial

In order to avoid production time waste, it is necessary to adjust and control various processing conditions before mass production to find out the best temperature and pressure conditions, for future daily operation.
keep the continuous products measurements and record the important dimensions (sample should be cooled to room temperature for measurement).Compare the samples size, pay attention to:

The optimization running operation should keep for at least 30 minutes until stable, then at least have a dozen of moulded samples, the make notation indicating the date , number and cavity , in order to test the its operation stability and the reasonable tolerance .
reasonable adjustments to reduce the overall cycle time.

screw forward time should be longer than the plastic gate freezing time; otherwise, the weight of the product can be reduced. And when the mould is heated, the screw forward time also need extend for compaction products.

wait until the machine and mould conditions to be stabilized, even for a medium-sized machine it may have to wait more than 30 minutes. Use this time to check the products possible problems.

adjust the pressure and injection volume to produce a product with satisfactory appearance. The flash should be avoided completely, especially for some moulded products not yet fully solidified. Little change in the filling rate may cause a great change in the filling.

clean the feeding system thoroughly prevents degradation compound or foreign material into the mould. Because they would be harmful for the mould operation. Check the material temperature and the mould temperature if suitable for the processing.

checks the barrel for the correct plastic material, and the correct drying (different raw materials for trial and mass production may lead to different results).

If the size of product is stable;

if some certain sizes have increase or decrease trend, and display machine processing conditions still changing, such as poor temperature control or oil pressure control;

The size change is within tolerance.

if the product size does not change also the normal processing conditions are stale, to observe whether each cavity moulded sample weight acceptable, the size should be within allowable tolerances. The consecutive unstable weight should be kept, in order to check the mould cavity size.
