How to Calculate the Cost of Die Sinking in Aluminum Alloy Die Casting Factories?

1. Classification of die cast tooling

The die cast tooling family is very large. According to the forming way and structure of the die, there are 10 main categories. Aluminum die casting factories mainly belong to the third category, the die cast tooling.

The first category is the stamping die. From the perspective of the forming method of the die, it includes the punching die, the bending die and the drawing die. From the complexity and structure of the die, there are the single operation die, the compound die and the progressive die. In addition, there are panel dies, combination dies and stacked riveting dies in the automotive industry.

The second category is plastic molding die. According to the molding material, it is divided into thermoplasticity and thermosetting. According to the plastic molding method, it is divided into compression dies, extrusion dies, injection dies, foam dies, blow dies and so on.

The third category is die casting mold. According to the forming method, there are hot chamber die casting and cold chamber die casting. According to the formed metal, there are non-ferrous metals and ferrous metals. Aluminum alloy die casting factory is in this category.

The fourth category is the forging molding die. There are large pressure, rotary pressure, horizontal forging machines, forging dies, cold heading for fasteners, extrusion dies, wire drawing dies, hydraulic forging. In the automotive industry, cold heading for fasteners is more common.

The fifth category is the casting die.

The sixth category is the powder metallurgy die.

The seventh category is the glass product die, which includes blow dies and pressure blow dies.

The eighth category is the rubber product die, which includes press dies, extrusion dies, injection dies, tire dies, O-rings and press forming.

The ninth category is the ceramic die, mainly includes shaped ceramic vessels.

The tenth category is the economic die, which is similar to simple dies.

2. The cost structure of the die cast tooling

The cost of the die is a big black box. As for the die cost, what we can see is the material cost, and the design cost can also be negotiated with the supplier. However, some costs are together with manufacturing costs and are invisible costs for aluminum alloy die casting factories, such as commission, transportation, verification, management costs, risks, profits, marketing, etc.

The cost structure of the die cast tooling:

It can be seen from this graph that the cost composition of the mold die casting includes design cost, material cost, manufacturing cost, transportation cost, commissioning cost, management cost, profit and others.

When the design cost accounts for a high proportion and the die design is reasonable, the subsequent commissioning cost will take up a relatively low proportion. On the contrary, later commissioning costs will be higher, and the material costs and manufacturing costs are the same.

3. Die cast tooling material cost calculation:

According to the product drawings, buyers will know the difficulty of the die cast and the level of product accuracy requirements. According to the die structure diagram, the complexity of the die cast structure can be known. According to the die cast materials, the proportion of die materials, die accessories and how long the development cycle is can be known. According to supplier information, it can be known what equipment the supplier is using and the level of the equipment.
