Die casting mold design process

For each die casting part it has its own production mold. When receiving new orders the first step is to design and fabricate the casting mold. Sieg-Huao can supply you one-stop solution from designing to manufacturing. Today we will discuss the design process of die casting mold in details.

1. Drawings. First of all 2D or 3D drawing is necessary for new part’s developing which clarifies dimensions, tolerances, standards, raw material requirements, surface finish requirements, spray requirements.

   
   

2. Choose of die casting machine with suitable tons. The low tonnage of die-casting machine will cause all kinds of abnormity and defects, speed up the loss of die life and increase the production cost.

3. Choose of the number and permutation of the cavity. Not all products need to use a model, many smaller products can achieve a model with multiple holes. According to the products’ geometric shape and precision standard, if the mold cavity can be arranged suitably the production cost will be saved a lot.

4. Determination of mould joint. The mould joint is determined according to these following principles. It can't affect the appearance; Guarantee the accuracy of products; Facilitate processing; Facilitate the design of casting system, exhaust system and cooling system; Easy for mold release. 

5. Select reliable supplier of standard parts. Generally, die-casting companies will have a long-term supplier for standard parts. In this way the quality can be guaranteed.

6. The design of pouring system and ejection system. The design of the pouring system includes the choice of the main channel, the shape and size of the sub-channel. The knocking-out of products can be divided into three categories: mechanical knocking-out, hydraulic knocking-out and pneumatic knocking-out.

7. Tooling fabrication. Choose suitable steel material and method of quenching to make the molds. 

8. Mold test. Install the mold to the die casting machine and die casting some samples to check the sizes, the surface quality and other aspects as per clients’ request. If the product fails to meet customer requirements, or the mass production is unqualified the mold needs to be repaired. 

In conclusion, to design and fabricate good quality die casting mold there are eight steps. Sieg-Huao has a professional team focusing on the tooling designing and manufacturing. The essential condition for good die casting parts is a good die casting mold. If you have any demands regarding to die casting mold please come to us and we will give you best price and best service.
