Incoming inspection
Inspection at material inward, before raw material storage and fabrication.
QUALITY & PROCESS CONTROL
Capability matters.
Control makes it repeatable.
Incoming, internal and final inspection, supported by documented manufacturing, grit blasting and painting processes.

Manufacturing process flow
From material inward to dispatch, including three inspection stages.
- 01Raw material inward
- 02Incoming inspection
- 03Raw material storage
- 04Laser cutting
- 05Bending
- 06Fit-up
- 07Welding
- 08Chipping
- 09Grinding
- 10Sanding
- 11Internal inspection
- 12Grit blasting
- 13Painting
- 14Final inspection
- 15Packing
- 16Finished goods area
- 17Dispatch
Grit blasting process flow
Surface preparation and roughness checking before painting.
- 01Clean surface with thinner
- 02Select G16 grit
- 03Set 6 bar pressure
- 04Select 8 mm nozzle
- 05Check sheet thickness
- 06Shot blast surface
- 07Select 1 m × 1 m surface
- 08Check surface roughness
THICKNESS BRANCHES3 mm → 1 foot distance
3 mm → 1 foot distance
5 mm → 1.5 feet distance
Shot blasting distances shown in the supplied process chart.
ROUGHNESS CHECK< 65 μm → repeat check / blasting
< 65 μm → repeat check / blasting
> 65 μm → painting
The process chart uses a 65 μm roughness threshold.
Painting process flow
Paint preparation, application, finish measurement and verification.
- 01Calculate surface area & paint quantity
- 02Mix paint, thinner & hardener
- 03Set 6 bar pressure
- 04Spray at 1 foot distance
- 05Two passes for one level of paint
- 06Dry in open space for 4 hours
- 07Check paint level against PO
- 08Measure DFT: 6 points per sq. metre
- 09Move to inspection area
- 10Peel-off test
- 11Dispatch after passing checks
PAINT LEVEL & DFT
Compare with the purchase order.
Additional paint application or return to the previous process follows the documented check result.
PEEL-OFF TESTPass → dispatch
Pass → dispatch
Fail → previous process
The finished component proceeds only after the relevant checks.
INSPECTION THROUGHOUT THE WORKFLOW
Three stages of inspection.
Specific finish checks.
The company’s documented process includes inspection at material receipt, during manufacturing and before dispatch.
Internal inspection
An internal check within the manufacturing sequence, before grit blasting and painting.
Final inspection
Inspection before packing, finished goods storage and dispatch.
6 points / m²
DFT measurement
Dry film thickness measurements at six points per square metre.
Peel-off test
Paint finish verification
Peel-off testing at the inspection area, with return to the previous process on failure.
