Powder recovery: what can be reclaimed and what cannot
A booth recovers 60–80% of overspray, but fines, moisture and colour decide what can go back in the hopper. Blend limits, PSD and the checks that hold.

Plant, quality and sustainability
Buyers audit a system, not a brochure. This cluster covers how Ganesh runs its plants: the ISO 9001 and ISO 14001 systems, in-process inspection, calibration and gauge control, pretreatment chemistry, the effluent treatment plant, maintenance, energy use and scrap recovery. It is written so a supplier-audit team knows what to ask for and what good evidence looks like.

How the plants run: quality systems, inspection, calibration, pretreatment chemistry, effluent, maintenance, energy and scrap.
Packaging cost versus damage: the right pack for fabricated parts
Packaging cost versus damage rate, modelled: what one damaged panel really costs, the break-even point for a better pack, and where over-packing loses.

Carbon and material efficiency in sheet metal plants
Where the emissions in a fabricated steel part actually sit: a material balance per delivered tonne, the numbers behind it, and the monthly record that proves it.
Read
Flatness measurement methods for sheet metal panels
Flatness measurement on sheet metal panels: support conditions, straight edge, surface plate, laser and CMM, and how to write a callout that can be inspected.

Calibration register: how instruments stay traceable
A calibration register is traceable only if each row links to an accredited certificate and a decision rule. What to record, and what to do when a gauge fails.

Scrap and yield: where material cost actually goes
How sheet metal scrap and yield move material cost: nesting gaps, kerf, skeleton, defect scrap, and the weighing records that turn a percentage into a number.

Pretreatment bath titration: what is measured and how often
Pretreatment bath titration explained: free and total alkalinity, free acid, pH, rinse conductivity and coating weight, with frequency and acceptance limits.

Compressed air leaks: the hidden cost in a fabrication shop
A 1 mm hole at 6.9 bar costs about 2,000 kWh a year. How to measure the leak load with a leak-down test, find the leaks, and prove the repair worked.

Supplier change without requalification: the first article still
A material or process change leaves the drawing untouched and moves the part. What a first article must measure when the revision never changes.
