Our Engineering Design Process: From Concept to Custom Equipment

Custom-engineered equipment doesn't start with a drawing — it starts with a conversation about a problem the customer's standard equipment can't solve. The process from there follows a consistent sequence, regardless of whether the end result is a coil-handling attachment, a testing machine, or a purpose-built system for an industry outside the usual product lines.

Step one: understanding the actual operating requirement

Before any design work begins, the requirement gets defined in operational terms: what material or product is being handled, what the dimensional and weight ranges are, what environment the equipment will operate in, and what the existing process's bottleneck or failure point actually is. Special purpose machines in particular exist because standard, off-the-shelf equipment couldn't efficiently handle a specific task — so the design process has to start by understanding exactly why that's the case, not just specifying a bigger or smaller version of an existing product.

Step two: structural design and analysis

Once the requirement is defined, load-bearing components go through Finite Element Analysis (FEA) to determine how the structure will behave under real operating loads. This step is where a generic concept becomes a specific, sized design — arm profiles, plate thicknesses, weld joint locations — all worked out analytically rather than by scaling up a similar past project and hoping the margins hold.

Step three: fabrication to certified standards

The design moves to fabrication using IS/EN-certified plate, with structural welding performed by coded welders. This is also where customisation actually happens in the metal — throat widths, arm curvature, mounting points, and dimensional ranges are built to the customer's specific equipment and process, not to a generic catalogue size — our C hook types and selection guide shows what that looks like on one product.

Step four: verification before dispatch

Finished components undergo non-destructive testing — typically magnetic particle inspection of welds — followed by proof load testing at a load exceeding the rated capacity (125% of safe working load for lifting equipment). This step exists specifically to catch anything that structural design and fabrication didn't get right, before the equipment ever reaches the customer's site. Equipment ships with a test certificate, load rating marking, and as-built drawing.

Step five: installation and commissioning support

For special purpose machines and larger systems, the process typically doesn't end at dispatch. Customer-oriented consulting and individual planning continue through installation and commissioning, since a custom machine's first days of operation are when any integration issues with the customer's existing process are most likely to surface.

Why the sequence matters

Skipping or compressing any of these steps — designing without analysis, fabricating without certified materials, shipping without testing — is how equipment fails in the field rather than in a design review. The sequence exists because each step catches a different category of problem, and by the time equipment reaches proof load testing, most of what could go wrong already should have been caught earlier in the process, not discovered by the customer after installation. Start a conversation about your requirement — that is where every custom build begins.
