Production Analysis of Precision Stamping Parts
08-21 / 2019

Precision stamping parts are a production technology that utilizes the power of conventional or specialized stamping equipment to directly deform the sheet metal in the mold, thereby obtaining a certain shape, size, and performance of product parts. Sheet metal, molds, and equipment are the three elements of stamping processing. Precision hardware stamping processing is a method of metal cold deformation processing. So, it is called cold stamping or sheet metal stamping, abbreviated as stamping. Precision hardware stamping parts processing is metal plastic processing





Large occupation of working capital. Many hardware companies, especially foreign trade processing companies, due to fierce competition, many customers adopt post payment methods, with payment terms often lasting for tens of days or months. Many companies' funds are firmly locked in the production line. In the case of price locking, furniture and hardware companies are likely to lose significant profits due to material price fluctuations, exchange rate issues, etc.




The cost of raw materials accounts for a high proportion of product prices. Generally, the profit margin of hardware components is very low, and they belong to low value-added products. Many products have raw materials accounting for 70% of the product price. Therefore, if the cost of raw materials can be reduced, it will have a very obvious effect on the profit increase of hardware enterprises. However, at the same time, if material waste is severe, logistics and warehousing costs are too high, and supply is not timely, it will greatly increase the cost of hardware enterprises, squeeze out their profit space, not only delay the entire production operation, but also lead to a large number of defective products.




Furniture hardware manufacturing is a process processing process, mainly using a relatively simple manual and assembly line production method. It requires relatively high coordination of various materials, and procurement management needs to focus on timely delivery of materials and quality assurance of delivery.




Some products have a relatively complex structure, and although sparrows are small, they have all five internal organs. In situations where large-scale mechanized operations cannot be achieved, defect rates and non-conforming products often occur, which can have a negative impact on the overall production system.
