Key Points Of Plastic File Box Injection Mold Design

When designing plastic file box mold, the points to be considered are box thickness, draft angle, support surface, reinforcement, rounded corners, holes, threads, inserts, etc.

1. The box wall thickness to ensure the necessary mechanical strength, box parts should have a certain thickness, but the thickness is appropriate.

2. The role of the draft angle to facilitate the smooth fall of the product.

3. The role of reinforcing rib is to increase the mechanical strength without increasing the thickness of the box. Preventing warping and deformation

4. Rounded corners of the inner and outer surface of the plastic box corner, in addition to the special needs or in the parting surface, core, and cavity with the outside should be rounded transition.

5. Plastic box of various holes, such as through holes, blind holes, screw mosquito holes, shaped hols, etc. should be opened as far as possible in the location of the box will not be honest weak strength, the shape of the hole should also strive not to make the mold structure complex

6. Plastic box may be added to a variety of inserts, the purpose is to increase the decorative effect, change the local performance (such as hardness, rigidity, wear resistance, etc.), improve the shape and size of the precision, reduce the amount of plastic, etc.
