Ganesh engineering library
377 guides on stamping, laser cutting, bending, welding, coating and the parts we build for lift, power, data centre, railway and farm equipment. Every article is reviewed by the engineering team before it is published.
Nine clusters, each mapped to a capability or product page.
How a sheet metal revision reaches the shop floor: which files and fixtures re-issue, how effectivity is written, and the revision block that stops old parts shipping.
How to move a press tool between suppliers: what to audit, what to take with it, the shut-height and capability checks, and when a new tool is cheaper.
IEC 61439 assemblies explained: who declares the rating, how design and routine verification differ, the temperature limits, and where the enclosure supplier's scope ends.
PPAP for sheet metal parts: the 18 elements that actually apply, what a Ppk of 1.67 demands of a tolerance, and the shorter pack industrial buyers can use.
Phosphating and conversion coatings for steel: iron versus zinc phosphate, coating weight in g/m², rinse quality and the checks that predict powder coating failure.
A shift handover that carries four states in writing: machine settings, material identity, quality status and open actions, and the record that keeps them.
How 6061 aluminium behaves bare, powder coated, painted and anodised, the galvanic couples that pit it, and the cure limit its T6 temper sets.
Data hall cable management by the numbers: 40% basket fill, 30 mm bend radius, support spacing and the bracket stiffness that stops a loaded tray sagging.
Weld distortion allowance by weld type: 0.5 mm transverse per fillet, 1 mm per metre longitudinal, 1–2° angular, and how to design a frame that absorbs it.
Every article names its reviewer and its sources. Read the RSS feed, or see the engineering team behind the library.
