The overall level of domestic sewing machines has increased significantly

Despite the gap between the world's high-end technologies, China's sewing machinery has continued to develop rapidly in recent years. Since the 1990s, domestic sewing equipment companies have reached a certain level of absorption and mastery of product technology and processes, and have steadily improved. They have the ability to transform and innovate themselves. Products range from raw materials and processes to appearance and performance. All have been greatly improved. Its main manifestation is:

1, process technology upgrade

In order to have independent production capabilities and to be close to the world's advanced level, the sewing machinery industry has now configured the casting process, forging process, powder metallurgy process, and blow molding process in the blank processing technology. Decorative processing techniques include spray painting, powder coating, screen printing and other coating processes, chrome plating, copper plating and other electroplating processes, carburizing and quenching, high-frequency quenching, and other material modification processing technologies.

The advanced casting production line has already been put into use in many enterprises. The spraying process of the casing surface adopts modern spraying technology and controlled drying tunnel, which replaces the traditional spraying process. The production capacity and quality level of the whole assembly line basically reach the international level; Some enterprises' casings have been processed with flexible processing lines and machining centers. CNC machine tools and centerless grinders have been widely used; precision gear machine tools have been widely used, and controlled atmosphere heat treatment technologies and equipment have been adopted by many companies. China's products have entered the international arena and have gone overboard. Technology and quality are the backing of these products.

2, processing technology upgrade

Judging from the supporting capabilities of parts and components, China’s parts and components are almost the most complete in the world. In particular, some key components such as rotary hooks, bevel gears, take-up rods, needles, and crankshafts are manufactured by professional manufacturers. Supporting ability is very strong.

After more than 20 years of unremitting efforts, domestic sewing machinery relies on the size of the cluster and supporting industries, and the product categories are continuously enriched. Except for individual special machines, most types of machines can be produced.

3, development and application

At the same time, the gap between domestically produced sewing machines and the international advanced level in terms of product development, technology application, process improvement, and informationization is also being shortened. The product quality and technical content of the conventional models, along with the continuous improvement of the production process, have been close to the international advanced level.

The advantages of good product quality and domestic labor cost make the domestic sewing machinery's price advantage obvious. The domestic equipment prices of the same grade are about 1/3 lower than foreign equipment. Good cost performance and service make domestic sewing equipment deeply internationally competitive. With the increasingly far-reaching influence, the "madeinChina" sewing equipment has become the proxy for quality and low price.
