Industrial Weighing Equipment & Gross Weight Scales Manufacturer

Welcome to Research and Development Enterprise “Polytechnic” — a recognized manufacturer of heavy-duty industrial dosing machinery and high-precision gross weight scales since 1988.

Our engineering team develops autonomous packaging solutions designed for reliable bagging of free-flowing bulk materials into open bags, valve sacks, or containers.

We supply specialized filling machinery for agricultural, chemical, woodworking, construction, and food processing facilities worldwide.

Every non-electric lever-type mechanism in our equipment delivers unmatched durability, operational safety, and resistance to environmental factors.

Modern industrial bagging units must function in harsh working conditions. Installing a mechanical gross weight scale provides consistent dosing performance without relying on electrical power supply or microcontrollers.

Since these mechanical units operate completely without delicate digital sensors, they remain immune to power surges, static electricity, high moisture, and heavy ambient dust.

Primary Industrial Sectors:

• Agricultural Production: Efficient bagging of wheat, corn, seeds, compound feed, granular fertilizers, and flour.
• Food & Grain Processing: High-speed batching of granulated sugar, salt, rice, legumes, and nuts.
• Woodworking & Biofuel: Packaging wood pellets, sawdust, wood chips, and biofuel briquettes into bags.
• Building Materials: Dosing dry mortar mixes, cement powders, fine sand, and gravel aggregates.
• Chemical Industry: Packaging plastic granules, mineral salts, soda ash, and chemical reagents.

Key Technological Benefits:

Mechanical counterweight technology allows complete explosion proof safety without complex ATEX certification requirements. The robust mechanical structure ensures decades of continuous operation with minimal routine maintenance.

Each unit features custom mechanical adjustments for target bag weights, fast clamping mechanisms, and seamless integration under existing hoppers, silos, or storage bins.
