Quality lab

We test here, so you don't test twice.

Dedicated instruments on the Qingdao floor. Every batch is measured against the drawing before it leaves — no invented certification claims; validated data only.

Salt-spray tester

Salt-spray tester

Corrosion testing to ASTM B117 — validate coating adhesion before parts leave Jimo.

Magnetic thickness gauge

Magnetic thickness gauge

Non-destructive coating thickness measurement on every batch.

Automatic colorimeter

Automatic colorimeter

Colour matching against OEM swatches and reference panels.

Melt-flow tester

Melt-flow tester

Polymer flow index checks for dip-coating formulations.

Drying oven

Drying oven

Controlled curing cycles for coating adhesion and hardness.

Resistance furnace

Resistance furnace

Material heat treatment and process validation.

Impact tester

Impact tester

Coating toughness and adhesion under mechanical stress.

What we measure

  • Salt-spray exposure (ASTM B117) in our Qingdao laboratory
  • Coating thickness by magnetic gauge
  • Colour matched on automatic colorimeter
  • Dimensional checks on every batch
  • Impact and adhesion before mass release

Inspection workflow

Five checks between your drawing and the container

Quality is built into the line, not bolted on at the end. Every order passes the same five gates.

  1. 01

    Incoming material

    Wire rod and polymer powder checked to spec on arrival — diameter, grade and batch recorded.

  2. 02

    Forming & weld

    First-off dimensional check and weld-strength inspection before a run is released to coating.

  3. 03

    Coating validation

    Film thickness by magnetic gauge and colour on the colorimeter, sampled through the run.

  4. 04

    Final QC

    Salt-spray (ASTM B117), impact and adhesion on samples; every batch measured against the drawing.

  5. 05

    Release & pack

    Test records filed and packed with the shipment; nothing leaves Jimo without sign-off.

Test methods

What we test to

The standards and methods our lab runs in-house. Exact acceptance limits are set on the approved drawing for your part.

ASTM B117 Salt-spray corrosion exposure
Magnetic gauge Non-destructive coating thickness
Colorimetry Colour match to OEM swatch / RAL
Melt-flow index Dip-coating polymer consistency
Impact & adhesion Coating toughness under stress
Dimensional Against the approved drawing
