Vacuum vacuum suction plastic moulding machine how to detect the difference between the quality stand or fall?

Vacuum vacuum suction plastic moulding machine how to detect the difference between the quality stand or fall? 1, the cohesive force of test: after vacuum forming slot no rebound, no shrinkage, such as doing peel test, on the PVC to stick with sawdust, middle empty plastic absorption on the edge of use or high temperature will soon take off. Do after the test method is: vacuum forming edge peel test, to see how much force will strip away, and see whether the skin after peeling PVC glue has a lot of wood chips, And wood completely said PVC more and are less suck plastic quality is poor, poor bond) 。 2, warm test: namely, high temperature resistant, low temperature performance, and moisture, around the climate is different, because such as warm sex bad vacuum plastic when the container export or summer high temperature especially easy to take off the edge and slot rebound. Minimum 75 ℃ qualified of heat-resistant, 65 - because of temperature in the container 70℃。 The most simple test of temperature resistance is blister directly in the sunshine after 24 hours, such as straight off half an hour or more with no edge, no rebound is heat-resistant good suction plastic, when the container or high temperature wouldn't have to take off the edge, slot rebound phenomenon. 3, particles presents detection: good vacuum suction plastic spraying blister after little or no pitting surface, after making products with poor like sand, let a person a see uncomfortable, at the same time seriously affected the image of the enterprise. Of carefully testing the above three aspects, the basic can determine the quality of the vacuum suction plastic quality.
