Engineered Workholding That Keeps Production Running Right

Fixtures & Jigs

Every time a component is loaded into a fixture, the outcome should be identical, same position, same orientation, same access, same result. When fixturing is engineered properly, quality becomes a system output rather than an individual achievement.

At RM Design & Engineering, we design and manufacture bespoke fixtures and jigs for customers who can't afford variability. Aerospace programmes where every hole position matters. Automotive production where cycle time is measured in seconds. Defence applications where reliability isn't negotiable.

Why Bad Fixturing Costs More Than You Think

We've seen it too many times.

A customer invests six figures in production tooling, builds a capable manufacturing cell, hires skilled operators, then loses repeatability because the fixturing was an afterthought. Components shift during machining. Assemblies don't close because bonding jigs allowed 0.3mm of creep. Inspection results vary between shifts because the check fixture doesn't constrain the part properly.

The fixture is the cheapest element in most manufacturing cells. It's also the one that determines whether everything else works.

We design fixtures that account for thermal growth, clamping distortion, operator access, and the realities of production environments where things get knocked, dropped, and used 200 times a day.

Capability

Our Fixture & Jig Capability

Our engineering team designs and manufactures bespoke fixtures and jigs for a wide range of applications:

Assembly Fixtures

Multi-component location and clamping solutions that maintain datum control across complex assemblies. We design for operator access, sequence logic, and the thermal behaviour of bonded joints.

Inspection Fixtures

Reference surfaces and location features machined to tighter tolerances than the components they measure, because your inspection data is only as good as the fixture holding the part.

Trimming Fixtures

Rigid, vibration-damped workholding for CNC trimming, waterjet cutting, and router operations. Designed to resist cutting forces without deflection or chatter.

Bonding Fixtures

Precision jigs that maintain positional accuracy through adhesive cure cycles, accounting for thermal expansion, bond-line thickness control, and component spring-back.

Drilling Jigs

Hardened bushings, accurate hole positions, and robust construction for repeated use. We design for chip clearance, coolant access, and tool life, not just hole location.

Check Fixtures

Go/no-go gauging, profile checking, and production verification fixtures that give operators immediate, unambiguous quality feedback without waiting for the CMM queue.

More Than Fixture Makers

Manufacturing Partners

We understand that a fixture is only as good as the manufacturing process it supports.

Our engineers consider the complete workflow, from component geometry and tolerances through to operator access, cycle time, and maintenance requirements.

Customers benefit from:

Improved manufacturing consistency

Reduced operator error

Faster cycle times

Lower scrap rates

Greater process confidence

Better long-term production outcomes

Why RM Design & Engineering?

Because Consistency Drives Quality

Many suppliers can manufacture a fixture.

Few understand the manufacturing process it supports.

We combine advanced CNC machining capability, practical engineering expertise, and extensive manufacturing knowledge to create workholding solutions that perform reliably throughout the production lifecycle.

We don't just manufacture fixtures.

We help customers achieve consistent manufacturing outcomes.

Engineering Expertise. Manufacturing Knowledge. Trusted Delivery.
