Hangzhou Sifang Weighing System Co., Ltd. has always focused on the field of modern weighing instruments. It is a high-tech enterprise with strong independent research and development capabilities and masters the core technology of weighing instruments. The company invests a lot of money every year in the research and development of new products and new technologies, has a number of invention patents and utility model patents, and has a number of advanced domestic technologies and products. The company is a high-tech enterprise, a member of the National Weighing Equipment Technical Expert Committee, a member of the National Standards Committee, and a drafter of many national standards.

The company is one of the few companies in China that have completely independently developed and produced dynamic weighing systems. Especially in the field of dynamic weighing, the company has been engaged in the research, development and production of this technology for a long time, and is currently one of the few in China. The dynamic system development unit with independent intellectual property rights is one of the drafters of the national standard "Dynamic Highway Vehicle Automatic Weighing Equipment" and the manufacturer who obtained the "Quartz Dynamic Highway Vehicle Automatic Weighing Equipment" metering equipment manufacturing license applied to high-speed weighing .

In recent years, the company has achieved significant results in road over-limit weight measurement testing, developed a low-speed/high-speed dynamic weighing system dedicated to highway inspection, and developed a number of dynamic dynamic weighing charges, over-limit detection, over-limit non-site law enforcement, etc. Weighing system uses various sensors such as shaft weighing scale table type, wide bent plate type, integrated small bent plate type, quartz type, etc. It has first-hand usage data for all sensor performance. It is a national overlimit weighing equipment for all types of overlimits. Manufacturers with rich and comprehensive experience in use are also some domestic manufacturers that can provide complete sets of over-limit detection systems. All core control systems and application platforms are developed by the company themselves.
