Can you repair a board instead of replacing it?

Usually, yes. Our automation lab repairs at component level — PLC CPUs, HMI panels, communication PCBs, drives and servo motors — and every unit is load-tested on the bench before it is returned.

The OEM no longer supports our machine. Can you still help?

That is exactly where retrofits shine. We migrate obsolete drives and controllers to current platforms while keeping the mechanical frame, and we can reverse-engineer spares that are no longer available.

How fast do you respond to a breakdown?

Mark the enquiry as an Emergency breakdown in the form. It is flagged to the 24/7 automation line instantly and an engineer calls you back. Standard enquiries are answered within one working day.

Do you manufacture from samples, without drawings?

Yes. Send the worn part and we measure, model and manufacture it — gears, shafts, sleeves, rollers and more — and keep the drawing on file for repeat orders.

Where can I get technical specs before I enquire?

Every figure in the Technical Product Catalogue has a printable PDF spec sheet. Use the Download spec sheet button under the blueprint.

What we do

Four disciplines. One accountable team.

From a single servo board to a full press modernisation, the same engineers diagnose, quote and deliver — so nothing gets lost between vendors.

Machinery Retrofits & Upgrades

Give proven press frames a modern brain — new drives, PLCs and HMIs without replacing the machine.

Drive & servo migration
PLC / HMI modernisation
Registration & web-tension control
Safety upgrades to current norms

Automation Lab Repairs

Component-level diagnostics on boards most people only swap. Tested on our bench before it ships back.

PLC, HMI & communication PCBs
AC/DC drives & power supplies
Servo motors & resolver recalibration
Load-tested, documented, warrantied

Precision Manufacturing

Critical spares machined to drawing — or reverse-engineered when the drawing no longer exists.

Gears, shafts & sleeves
Rubber roller re-compounding
Mandrel balancing & re-tubing
Reverse engineering of obsolete parts

Industrial Spares & Supplies

The everyday wearables that stop a line when they run out — dispatched fast.

Blades, bearings & belts
Pneumatics & valve manifolds
Sensors, encoders & cables
PPE and plant consumables

How an engagement runs

From ticket to handover, in four steps.

01
Ticket & triage
Your enquiry gets a ticket number and lands with an engineer, not a sales queue. Emergencies trigger an instant alert.
02
Site survey or bench test
We inspect the machine on site or diagnose the part on our bench, and document the fault with photos and readings.
03
Fixed-scope quote
A clear scope, parts list and timeline — planned around your production schedule to minimise downtime.
04
Execute & hand over
Repair, retrofit or manufacture, then commissioning, parameter backups and a written handover report.

About the Guild

Engineering support, end to end. Zero excuses.

At The Engineering Guild, we deliver industrial engineering support ranging from high-precision machinery retrofits and component-level electronic repairs to bespoke manufacturing of critical spares and rapid supplies of everyday plant wearables.

RESTORE

Worn mechanical systems returned to factory-spec tolerances — balancing mandrels, re-tubing shafts, re-compounding heavy rubber rollers.

REPAIR

Component-level diagnostics on PLCs, HMI panels, communication PCBs, AC/DC drives and servo motors with optical resolver recalibration.

MANUFACTURE

Bespoke critical spares — gears, shafts, sleeves and rollers machined to drawing, not approximated.

SUPPLY

Rapid dispatch of everyday plant wearables — blades, bearings, belts, pneumatics and PPE.
