Die Casting Mold Calculating Guide – What’s The Cost Of A Mold Die Casting

How to calculate the cost of die-casting mold? Die casting is a kind of precision casting method that uses high pressure to melt metal into a complex metal mold. Here is everything you should know about the cost of the die casting mold.

​

Standardized Mold Cost Accounting Method:

From the perspective of the cost composition of mold processing, it is relatively easy to identify and calculate whether it is designed to cost, material cost, profit, and management cost commissioning and transportation cost, and standard parts cost as long as we patiently collect data and carefully calculate; The most difficult part of the mold processing cost is the processing fee, which is also the part with more water in the manufacturer. In the process of machining, from the initial rough machining to the subsequent finish machining, and then to the subsequent EDM, wire cutting, polishing, etc., the labor and mold investment is relatively difficult to identify the corresponding cost if not for the personnel with relevant work experience, but you can learn from the experience of different suppliers, Summarize to know the approximate cost composition of this kind of parts.

 

The Composition Of Mold Cost

1.Split the cost components;

2.The calculation formula for determining cost components

3.Determine the source and accuracy of data;

4.Form the model according to the previous steps.

 

Mold Supply Chain Model

There is a corresponding time cycle during mold manufacturing and processing. Through the time cycle and combined with the manufacturing process, we can find the average price on the market and make an estimation, to get rid of a certain amount of water. For example, some positions are double shift and some positions are single shift. Check whether the processing time matches according to the details given by the supplier, to deduce the supplier’s cost composition. Only by knowing the supplier’s supply chain and the cost level of his supplier can we know the cost level of this supplier. Generally speaking, the traditional mold factory has three profit points: material cost, processing cost, and management cost; Therefore, we must understand the price of raw materials.

 

The Cost of Die Casting Mold Consists Of

1. Design cost;

2. Material cost;

3. Processing costs;

4. Management and labor costs;

5. Inspection cost;

6. Mold trial cost;

7. Transportation costs;

8. After-sales expenses;

9. Taxes

 

Material costs and design costs are relatively visible. Other costs such as manufacturing costs, commissioning, transportation, verification, management costs, profits and other expenses belong to the black box, and a mold cost accounting mechanism shall be established. Supply chain information sharing needs to be further strengthened, such as design change information, demand forecasting, etc. The cost of a pair of molds basically includes the above 9 parts of the cost. Generally, the mold factory will also calculate the auxiliary cost, about 5% of the mold cost, and the rest is the profit of the mold.

 

1. Design cost:

It is closely related to labor cost, so it is necessary to understand the salary level of the supplier’s region in order to better estimate labor cost. Mold design generally includes CAD structure design & 2D drawing, CAE mold flow analysis, and CAM programming. However, when considering the cost of mold design, we usually consider only the cost of CAD and CAE. The design cost generally depends on the size and complexity of the mold. In fact, the quotation of the mold factory is different. In general, large molds account for 2% of the total cost, and the design cost of small molds accounts for 2.5% ~ 3%. The design generally includes CAD structure design & 2D drawing, CAE mold flow analysis, and cam production department programming.

 

2. Material cost:

The materials of mold die casting mainly include the cost of die frame (frame) and die core (kernel). The mold base is divided into a self-made mold base and a standard mold base. As the larger, the tonnage of the mold, the greater the travel requirements of the mold base processing equipment, most mold factories purchase outsourced mold bases and standard mold bases.

 

The larger the tonnage of the mold, the larger the mold base. Generally, the larger the mold base, the lower the cost. The accounting cost is directly calculated according to the weight, but the gap part of the molded foot should be removed. The material of the die frame is selected according to the design life of the mold die casting. Since the die life of aluminum alloy is generally 80000 ~ 100000 times, the die base can be reused, so we need to consider the reuse of the die frame in our daily replication die.

 

The mold times of soft mold are very low, only hundreds of mold times. You can directly use mold core material instead of the mold base. The material cost is mainly the cost of mold base and mold core. It should be noted that if the service life of the mold is up and the copy mold is ready to be opened, it is necessary to identify whether the mold base can be reused; If it can be reused, the cost of copying molds can be greatly reduced. Heat treatment cost: for die-casting molds, the heat treatment cost is also a big head, including the cost of quenching and tempering, vacuum quenching, nit riding, and other steps. The specific cost depends on the scale of the supplier.

 

3. Manufacturing cost:

Including machine tools, spark machines, wire cutting, and other equipment costs and labor costs such as mold matching and polishing. The processing cost of general mold can not exceed 20% of the whole mold cost.

 

5. Inspection cost:

It mainly carries out process inspection and subsequent delivery inspection on the key dimensions, electrodes, and core of the mold, and the inspection cost accounts for 1-2% of the total cost.

 

6. Trial mold transportation and packaging cost:

The internal constant of general mold companies is the two mold test index, and the mold test cost below 800t mold is 1-1.5%; The cost of mold test above 800t is 2%. The die test cost of aluminum alloy die casting is relatively cheap, while the die test cost of magnesium alloy die casting will be higher, because magnesium alloy has higher requirements for material safety performance; The material unit price of magnesium alloy is higher; The furnace with magnesium alloy die casting is different from that of aluminum alloy. It should be noted that generally, the number of mold trials should not exceed 3 times. If more than 3 times, the cost of mold trials should be borne by the mold factory because there are problems with their molds, which leads to the need for multiple mold trials. In addition, the parameters of the equipment must be debugged accurately to ensure a smooth mold test.

 

7. After sales and taxes:

1. The after-sales service fee generally accounts for 5%, except for molds with special requirements.

2. Generally, the company will bear 9% of the tax after deducting the material deduction.
