Factory Price Fishing Scale Weight Hanging Spring Scale 4.5KG Mechanical Scale

A hanging spring scale is a simple mechanical scale that measures weight by the extension of an internal spring. The hook at the bottom holds the item. A dial or marker slide shows the measured weight. These scales use pounds and kilograms and work without batteries. People use them for fish, luggage, produce and small cargo.

RTI’s Hanging Spring Scale is a compact mechanical scale rated to 4.5KG (10LB). It has a stainless steel hook, a contoured grip and a marker slide to record peak weight. The case uses a metal finish and the design is built for easy handling during outdoor use. RTI supplies wholesale and OEM orders; we support custom branding and bulk packaging for distributors and manufacturers.

• Peak-hold function: The marker slide records the highest value. This helps when weighing moving or live catches.
• Durable contact parts: The stainless steel hook and robust spring reduce wear. This lowers maintenance and replacement costs.

4.5kg Portable Mechanical Scale Manufacturing Process

1. Design & specification: Finalize dimensions, scale capacity and materials. Create drawings for the housing, spring and hook.
2. Material procurement: Source stainless steel for hooks and approved metals/plastics for the body from certified suppliers.
3. Spring forming & calibration: Produce and heat-treat springs to deliver consistent force-extension behavior. Pre-calibrate springs to spec.
4. Metal forming & machining: Stamp, cut or machine the housing and internal parts. Deburr and prepare parts for assembly.
5. Assembly: Fit spring, dial, marker slide, hook and swivel ring. Secure components and install final body and grip.
6. Quality check & calibration: Test each batch on calibrated weights. Adjust marker slide and spring settings where needed.
7. Surface finish & packaging: Apply metal finish, assembly checks, then pack. Offer custom boxes, labels or printed logos per OEM requests.
8. Pre-shipment inspection & logistics: Final QC sampling, documentation and arrange shipping. Provide export packing and required compliance documents for wholesale clients.
