1). Dimensional Control
When you get your plastic parts from your supplier, you should check the dimension at first time. because of based on your design, you must have some critical dimension or normal assembly dimension which should be made accurately to match other components of your products, if these dimension made incorrectly, you can never fit it right or properly.
2). Cosmetic Control
Since plastic parts is soft and easy to scratch when manufacturing and transportation, you should always check the appearances before the parts is used. normally you may find sink marks, deformation, scratch, or flash on it. these defects can never be accepted when product assembly
2). Assembly Testing
It’s most simply way to have a quick check of your plastic parts by assembling the parts to other components. and you can find out if the structure and dimension of the parts are correctly produced, if not, you should check with your design drawing which describe clearly on the structure and dimension.
