Aluminium Parts For Evaporators

Product specification

Product show

1, the product wall thickness should be uniform, the wall thickness difference can not be too large. And the thickness should not be too thick (bubble, sand hole phenomenon will be more) nor too thin (poor filling, difficult to shape)

The thickness is determined by the die-casting area of the product. The greater the area, the greater the wall thickness should be, generally between 2.5mm and 4mm. The minimum is 0.8mm and the maximum is 6mm. If the product is too thin or the deformation is serious after die-casting, the reinforcement should be made.

2, some positioning holes, high precision hole, die casting can not be fully formed, can only do cone pit first, and then processing molding.

3, products as far as possible do not have sharp corners, generally R1.0 rounded corners.

4, the product should have demoulding slope in the direction of mold opening. The external drawing die is generally 1°, the internal drawing die 2-3°, easy to demoulding.

5, the casting hole and the casting hole or casting edge to keep a certain distance B(B>1.5mm).

6, as far as possible to reduce the internal sag structure, to avoid core pulling around the problem.
