Factors Affecting The Price Of Hardware Precision Parts Processing

Factors affecting the price of hardware precision parts processing

Complex designs double the price

Many people don't know that a seemingly simple part may have several unique structures, which will lead to a sharp increase in processing costs. For example, parts with special-shaped holes or non-standard threads cannot be processed by ordinary machine tools, and high-end five-axis equipment must be used.

Such a design often has to go through a lot of clamping and complicated programming, and its scrap rate is much higher than that of ordinary parts. Factors affecting the quotation of precision parts processing Factors affecting the quotation of precision parts processing . For this reason, manufacturers will naturally increase their quotations in order to cover costs.

The price difference is three times if you choose different materials

The price difference between the three materials of stainless steel, aluminum alloy and titanium alloy can be as much as two or three times, and the price of titanium alloy itself costs several hundred yuan per kilogram, which is much more expensive than ordinary steel.

More importantly, the titanium alloy used for processing has many difficulties in the process. The tool wears extremely quickly, so the cutting speed has to be slowed down, and these potential costs will eventually be amortized into the quotation.

Accuracy requirements determine equipment grade

The higher the accuracy requirements, the more expensive the price will be. Micron-level processing requires machine tools with nanometer-level precision, and such equipment itself is very expensive.

If you want to carry out high-precision processing of hardware precision parts, you must cooperate with a series of inspection methods such as three-coordinate measuring instruments. As a result, the cost of quality inspection is obviously not low. Skilled workers will need to spend longer looking at the machine tools, and labor costs will increase accordingly.

Batch size affects unit price

In mass production situations, a set of fixtures can be used repeatedly, so the cost amortized to each part will be extremely low. However, for small batch orders, the unit price is increased for the same preparation time.

Some manufacturers will charge additional startup fees or commissioning fees for small batch orders. This is also common practice in the industry. Before customers place an order, it is best to clarify the quantity they require, so as to facilitate price comparison.

Special craftsmanship significantly increases the price

Special processes such as EDM, wire cutting, and laser processing are much more expensive than ordinary turning and milling. The usage fees of special equipment must be taken into account, the maintenance fees of special equipment must be taken into account, and the energy consumption of special equipment must also be taken into account.

There is a situation where some parts must be produced with the help of special processes. In this case, there is no other choice. When manufacturers perform quotation operations, they must be able to clearly list the part of the cost separately, so as to prevent possible subsequent disputes.

Regional differences cannot be ignored

In regions represented by the Yangtze River Delta and the Pearl River Delta, competition is extremely fierce, and prices are relatively transparent and affordable. In sharp contrast, in some remote areas, technical resources are scarce, suppliers are few in number, and quotations are usually high.

There are differences in labor costs in different regions. Labor costs are higher in the southern coastal areas, while labor costs are lower in some northern areas. This is also a key factor affecting the quotation.
