The cost and quotation calculation of metal stamping dies

The quotation of the mold is very important, and it is also a very tedious calculation. This work is usually done by a senior mold design engineer. Because the mold cost and quotation calculation will greatly affect the company's profit and whether it can receive orders, if the quotation is too high, it is easy to lose customers, and if it is too low, it may affect the company's profit. It may also be used as a cost budget basis for customers in the new project stage. The first step is to analyze the stamping process. It is very important to analyze the stamping process of the mold. For simple products, senior mold designers can basically quote customers directly by using the simple mold quotation method described later, and should be For products with complex shapes, a comprehensive analysis of the stamping process is required. Some 3D forming parts even require professional 3D software to analyze the forming process. 2. Calculate the material expansion of the product parts and carry out the layout. Most products can be directly expanded. If the laser cutting processing is done in the first step, this step will be quite easy. 3. List the number of work steps or projects. For continuous mold structure, divided work steps, and single project process mode, you need to list the number of molds. Of course, when necessary, we can suggest that customers make some appropriate adjustments based on their product complexity and production quantity. 4. Calculate the die surface size. After the punching force is completed, the die surface size is basically obtained. The punching force can be calculated with the help of some professional software, or it can be calculated by a simple calculation method. After these steps, we can get the type of production material, width and tonnage of the punch required by the mold. For some complex products, it may be necessary to make samples in advance to determine some of the manufacturing processes. Can it be planned? 2. Stamping die cost calculation 1. Die material costs such as the template material, the milled national standard Cr12MoV is one of the commonly used materials, and the template blade will be inlaid with better materials Cr12Mo1V1, D2, DC53, etc. 2. The cost of spare parts includes punches, inserts, and other spare parts. 3. The processing fee is generally estimated by time. Of course, it can be calculated directly by weight, such as heat treatment. The wire cutting processing fee is calculated by the square, which can basically estimate a more accurate value. 4. The management fee depends on the size of the factory. If it is a 300-person factory, I personally think that about 15% to 25% of the management fee can be charged from the mold cost. And if it is a processing shop, then 10% is already a lot. Third, mold quotation From the mold cost obtained above, we can make a mold quotation. Fourth, simple mold quotation A simple mold quotation method is provided below. Here we directly calculate the production cost of the entire mold based on the size of the mold surface. This quotation method is suitable for uncomplicated parts and not too many holes, and the mold is not special. If required, the size of the mold surface has a greater relationship with the mold cost and can be directly converted into a quotation. 1. Continuous mold size quotation u003d lower template mold surface size, length * width * 0.25 such as 400W*1000L continuous mold calculation, 400*1000*0.25u003d100000 yuan This is a set of one-meter-long continuous mold of ordinary sheet metal parts Add 20% to the quotation of auto molds of the same size at the cost price, 100000*1.2u003d120000 yuan2. For single engineering mold quotations, adjust the coefficient of 0.25 accordingly and change it to an approximate value of 0.11. For example: u003d lower template mold surface size, length*width*0.11u003d1000*400*0.11u003d44000 yuan, plus 20% for auto parts mold. 20% premium for ordinary stamping dies for auto parts.
