OIML approval for X1M/X3AM/X3M/X5M indicators, with EC Type Approval and new test standard of 10V/m
Since the establishment of Shanghai Scales & Accessories Factory in 1998, we have been committed to the development and improvement of weighing technology and system. We provide solutions for every weighing, with the goal of obtaining the fastest and most accurate results in the weighing process.
With manufacturing base in Suzhou and surrounding cities, we can provide one-stopsolutions for almost all weighing demands. From accessories to complex systems, from 0.01mg precision balances to 200 ton high capacity weighbridges, we are doing our best to make your weighing more accurate, whether in the manufacturing process, or in-line packaging for shipping, retail or customized weighing system.
Our products are sold in more than 80 countries and have more than 100 distributors worldwide. With a global distirbuting network, we can provide fast and reliable after-sales service and installation guidance, whether you are in the equator or the North Pole, 7×24 technical support!
Value each gram for weighing in industry, farming, retail, lab, medical and logistics!
We believe true expertise stems from a deep understanding of industrial environments. Our R&D team focuses on one mission: transforming complex on-site requirements into stable, precise, and reliable core technologies.

By immersing ourselves in various industrial settings, we develop specialized instruments tailored to specific application needs. For demanding conditions such as meat and food processing, we offer IP69K-rated instruments designed to withstand high-pressure washdown, corrosive media, and saline atmospheres. In livestock farming, we provide integrated animal management software, delivering a digital closed loop from weighing to data-driven management.

Centered on the Hiweigh Full-Process Quality Control System, we integrate lean manufacturing throughout development to delivery. Through continuous process optimization and systematic quality management, we achieve simultaneous improvements in both production capacity and product quality, maintaining defect rates within excellent margins while ensuring consistently high performance and long-term reliability.

The system encompasses a closed-loop from engineering validation to mass production. Pilot units undergo systematic whole-machine validation to ensure design integrity and process stability. Mass production relies on inspection checkpoints across all processes and a full traceability system, enabling performance verification for every unit. Packaging and logistics solutions are also validated through simulated environmental testing to ensure structural and functional integrity under complex transport conditions.

Production begins with digital precision machining. Using high-power laser cutters, we achieve cutting accuracy within ±0.01 mm, setting a precise foundation for subsequent operations. Sheet metal is accurately formed by CNC press brakes, ensuring structural strength while enabling high-precision modular assembly.

In welding and assembly, all personnel complete specialized training and qualification under senior production engineers. Welders follow defined sequences and techniques to control thermal deformation, with critical welds subject to non-destructive testing. Every screw is fastened using calibrated electric torque tools, with torque values recorded and linked to the product serial number for full traceability.
From R&D grounded in real industrial needs, through closed-loop iterative quality validation, to human-machine collaborative precision manufacturing—Hiweigh follows rigorous engineering logic throughout. This ensures not only fully verified and reliably delivered solutions, but also a lasting commitment to quality worthy of long-term trust.
