From plastic granules to a calibrated scale

Complete production control is not a slogan here — it is a floor plan. Stamping, welding, moulding, coating, assembly and calibration all happen inside the same 30,000 m² plant.

Production process

Six stages, one roof

Every stage is owned. Nothing critical is outsourced to a supplier we cannot audit ourselves.

01

Raw material

Plastic granules and hardware metal enter the plant, batch-tagged.

02

Stamping & forging

Decks, frames and brackets pressed on our own presses.

03

Robotic welding

Repeatable welds on platform frames — no operator variance.

04

Moulding & coating

Injection moulded housings, powder coated steel parts.

05

Assembly

Load cells, PCB, display and keypad fitted on flow lines.

06

Aging & calibration

Units rest in the aging area, then are calibrated before packing.

Machines we own, not rent

Owning the process changes three things for a buyer: the quality curve stays flat across batches, the supply chain cannot be interrupted by a third party, and the cost structure leaves room for a better price at the same specification.

Quality control

Where accuracy is decided

The load cell is the heart of a scale. We engineer and manufacture ours in-house, then seal and oxidise the surface so moisture cannot reach the strain gauges.

Incoming

Raw material and component batches are checked before they enter the line — plastic grade, steel thickness, PCB function.

In process

Welding parameters, coating thickness and torque values are fixed per station and checked on every shift.

Before packing

Every unit is powered, aged, calibrated against reference weights and re-checked before it goes into a colour box.

Come and see the line.

Yongkang is 40 minutes from Yiwu and 2 hours from Hangzhou. We can arrange pickup and a full day on the floor.
