The main criteria for testing are:
Casting 3D diagram /2d, customer characteristics requirements and so on.
1, full size test
A full size inspection of the die castings for the first time produced by the new die casting die can effectively avoid the hidden danger of product size problems in the subsequent die casting production, especially the size matching parts with other parts.
A full size inspection is made for every newly manufactured die casting die, ensuring that every size is within the tolerance range, which can effectively avoid similar problems.
2, performance test of die casting
With the continuous expansion of the scope of application of die casting, die casting of various performance requirements are also increasing, the commonly used destructive test, air tightness test, the machine after the (shrinkage) test, performance test was carried out for the first new related production, it is necessary to do;
When the castings can not meet the requirements of these properties, it is necessary to analyze the mold, find the reasons, and solve the problem.
Sometimes the slight change of mold gate will change the filling state of the mold, and the filling state of the mold will affect the structure, compactness and mold exhaust of the product, which will lead to the change of the quality of the die castings produced.
