Ningbo fastener production costs will be greatly reduced

Abstract: Recently, a large-scale precision environment-friendly automatic large-scale cold heading machine was successfully developed and went offline at Ningbo Sijin Machinery Co., Ltd., located in Ningbo High-tech Zone, and declared a breakthrough in the production of fasteners such as screws and bolts. Firmware company manufacturing costs will be greatly reduced.

Cold heading is a kind of production process relative to enthalpy. It is characterized by high precision, high efficiency, high quality, and low consumption. The cold heading machine is used to produce all kinds of standard parts, fasteners and special-shaped workpieces. With this machine, the steel is directly heated in the cold heading machine without heating, and it will “spitting” the screws and bolts. Firmware and shaped parts.

In the past, domestic cold heading machines generally produced fasteners such as screws and bolts with a diameter of 30 mm or less. This large-scale machine weighing nearly 200 tons broke through this limitation and can produce fasteners and shaped parts such as bolts with a diameter of 30-34mm, and it can be cold-formed once. According to statistics from relevant departments, the total global demand for fasteners has increased by an average of 5% annually. In the coming years, the demand for fasteners will continue to grow at a rate of 12.5% ​​per year in China. The advent of large precision environmental protection automatic cold forming equipment will increase the competitiveness of China's fastener industry.
