What Are The Cost Calculations For Precision Sheet Metal Processing?

What are the cost calculations for precision sheet metal processing?

Raw material costs

Within the scope of sheet metal processing costs, raw material costs are the most basic part. It is generally calculated based on the maximum length and width of the part after expansion, along with the thickness and density of the plate. The calculation formula is the weight of the material multiplied by the unit price of the material. For example, in 2025, a sheet metal factory in Suzhou received a batch of orders for chassis, using cold-rolled steel plates with a thickness of 1.5 mm. The price per ton is about 4,500 yuan. After unfolding according to the drawing, the material cost of a single piece is 12.6 yuan. In the actual work process, the utilization rate of the panels needs to be taken into consideration. This is because scraps will be generated during the blanking stage. These scraps cannot be fully recycled, which will indirectly increase the actual material cost of each product. Therefore, sheet metal processing mold cost analysis , try to choose standard size sheet metal processing mold cost analysis when purchasing. What are the cost calculations of precision sheet metal processing? , can reduce waste.

Hardware accessories cost

The purchase cost of standard parts such as various locks, hinges, handles, nameplates, rivets, etc. required for this product is called hardware accessories costs. For example, an industrial control chassis may require 4 stainless steel hinges and 2 special locks. These accessories are purchased at the local hardware market in Suzhou and the cost of a single set is about 8 yuan. In terms of brand and material, different customers have different requirements. For example, if they require the use of imported locks , the cost will increase. When the manufacturer performs accounting, it will count the accessories model and quantity one by one according to the drawing list, and then add the transportation and procurement labor costs, and finally allocate them to each product.

加工成本

Cutting cost

The first step is blanking in sheet metal processing. Commonly used equipment includes laser cutting machines, CNC punches and shears. Laser cutting machines have higher depreciation and amortization, but they have good accuracy and fast speed, and are suitable for complex shapes. For example, Suzhou Chaoshang Precision will use a 3000-watt laser machine for blanking in 2025. The depreciation plus electricity cost is about 80 yuan per hour, and it can cut 30 parts. The cost of a single part is 2.7 yuan. However, the cost of using an ordinary punch machine is lower, and it only requires customized molds, which is suitable for mass production. The selection of different equipment directly affects the level of processing costs, and needs to be decided flexibly based on the order volume.

Formation cost

First of all, forming is mainly accomplished by bending machines and welding equipment, and the cost is related to the number of bending knives and the length of the weld. For example, there is a server chassis that requires 10 knives to be bent. The man-hour cost for each bend is about 0.5 yuan. Including equipment depreciation, the bending cost for a single piece is 5 yuan. For the welding part, if full welding and polishing are required, the welder's daily salary is about 400 yuan. With the addition of welding wire and argon gas, the welding cost of a single piece can reach 15 yuan. The skill level of workers will also have an impact on efficiency. Skilled workers can complete 6 pieces per hour, while novices can only do 3 pieces, which will double the cost of working hours.

Surface treatment cost

Spraying, wire drawing, electroplating, oxidation, etc. belong to the category of surface treatment, and the cost is calculated based on area or weight. Take the chassis as an example. It requires electrostatic powder spraying. In 2025, the quotation given by the Suzhou market is 18 yuan per square meter, and the spraying area of ​​a chassis is 0.6 square meters, so the cost is 10.8 yuan. If the customer requests wire drawing treatment, an additional NT$2 will be charged per piece. There is a big difference in the cost of different processes. For example, anodizing is 40% more expensive than ordinary spray painting, but it has better corrosion resistance. Manufacturers must select the appropriate process based on the use environment of the product to prevent over-processing and increased costs.

Shipping and packaging costs

The transportation cost is calculated based on the batch, and then allocated to each product. For example, the freight from Suzhou to the customer warehouse in Shanghai is 800 yuan. This truck can load 200 chassis, so the transportation cost of a single unit is 4 yuan. In terms of packaging, each product needs to be protected with foam and cartons. The cost of purchasing a set of packaging materials from Suzhou is 2 yuan. If the customer requires wooden boxes for reinforcement, the cost will increase to 8 yuan. Although these costs may not seem large, the cumulative impact on profits is quite significant. Especially for small batch orders, the proportion of transportation may reach 10% of the total cost.

management and profit

Management expenses cover factory rent, management personnel salaries, water and electricity, etc., and are usually apportioned according to 10% to 15% of the total cost. For example, there is a medium-sized sheet metal factory in Suzhou. The monthly rent is 20,000 yuan. In addition, the salary of three clerks is 15,000 yuan, which is spread to 1,000 products per month. In this way, the management fee per product is 35 yuan. Profit is the guarantee for the company's continued development. It is generally added to 5% to 10% of the total cost. For example, the total cost of an order is one hundred yuan, and after adding ten yuan of profit, the quotation is one hundred and ten yuan. Reasonably controlling these indirect costs can improve the competitiveness of the quotation.
