Production of sewing machine parts --- metal injection molding

Some parts produced by metal injection molding technology

Metal injection molding is known as "the most popular part molding technology today". It is a new powder metallurgy near net molding technology that extends from the plastic injection molding industry (near net molding technology refers to the molding technology of mechanical components that can be used only with a small amount of processing or no processing after parts are molded. This technology has been vigorously promoted in China and has been widely used in industrial production and scientific and technological fields). The metal injection molding technology was first introduced by the National 863 Program. It can manufacture high-density, high-precision, high-strength, three-dimensional complex structural parts. It has the advantages of low cost, high efficiency, good consistency, good wear resistance, high temperature resistance, etc., and is easy to form batch production. It is reported that the technology has been successfully applied to the production of sewing machine parts, and has been highly recognized and praised by the industry.

Taking the production of rotary shuttles for sewing machines as an example, the traditional production method generally uses cold extrusion to produce blanks. Although the cost of blanks is low, it requires more than 200 processing procedures, with high labor costs and low efficiency. For the rotary shuttle blanks produced by metal injection molding technology, only two sides need to be turned and one knife is needed during processing, and the finished products can be produced in 10 processes at most. More than 100 processes are saved compared with the traditional process, which greatly shortens the production cycle and saves a lot of labor. For the products produced by metal injection molding technology, due to one-time molding, there are few cutting materials, the scrap rate is low, and the energy consumption and management fees such as water and electricity charges and machine depreciation are reduced accordingly, which greatly saves production costs. For example, using metal injection molding technology, 20 workers can produce about 300,000 rotary shuttle blanks a month, while using traditional technology, the production of 300,000 rotary shuttle blanks a month requires thousands of workers to cooperate. In a word, the new process of metal injection molding can reduce the labor cost by about 80%, reduce the overall cost by at least 20%, and greatly improve the production efficiency.

It is understood that Qinhuangdao Zhongwei Precision Machinery Co., Ltd. is a private enterprise specializing in powder metallurgy research and product production. With its sophisticated metal injection molding technology, it can mass produce various parts of sewing machinery and equipment, such as the rotary shuttle of sewing machines and the rotary shuttle of shoe machines. The metal injection molding process was first used in the automobile industry. On average, more than 20 kg of parts were produced by the metal injection molding technology on a car in the United States, while less than 1 kg of parts were produced by this technology on each car in China. The market development potential is huge. Metal injection molding technology is a new material and process worthy of the name. It has broad development space. When applied to the sewing machine industry, it will bring a technological revolution to the production of sewing machine parts and bring unexpected economic benefits to related enterprises.
