When it comes to the die casting tool design, we will make it to stand longer tooling life and repair easily.
The above photo shows a cylinder part and please pick up on the fins structure. This is the critical area where it is easy to crack and material to stick on the mold.
Two options are considered for design,
1) whole inner mold
When material stick on the mold during the die-cast, you have to dig out the material from those deep grooves in cavity block. In addition, the cavity block needs to be welding in the wake of fins breaking.
2) cavity insert
We design it by several slices of fin, each fin is an insert to be one of the component of inner mold. The fin is easy to be replaced. We opted for this one even though it takes time and costly.
