CNC MACHINING, PROTOTYPING & SMALL BATCH PRODUCTION

Machining, laser and prototyping under one roof, helping teams move from prototype to pre production and batch supply.


 
 
 

Specialising in CNC machining and manufacturing services, we continually invest in the latest engineering technology to deliver high quality components with exceptional accuracy.

With an innovative and collaborative approach, we act as an extension of your team, supporting UK manufacturers, product designers, and engineers with reliable CNC machining, batch production, and prototyping.

Watch our video to see how we combine capability, flexibility, and personal service to keep your projects moving.

CAPABILITIES UNDER ONE ROOF

We bring machining, laser and prototyping together under one roof to support designers, engineers and product teams from prototype through to batch supply.

CNC milling aluminium component with coolant and chips during machining.

CNC MILLING

Aluminium, stainless steel, brass and engineering plastics machined for housings, heatsinks, brackets and hardware. Supports prototypes, pre-production and batch supply.

CNC turning with Y-axis milling for complex features on brass component.

CNC TURNING

Turned components with Y-axis milling for features, threads and mounting details in aluminium, stainless and brass. Ideal for lighting, hardware and electro-mechanical builds from prototype to pilot supply.

Laser cutting custom foam insert for packaging and product protection.

LASER CUTTING

Laser cut plastics and optical panels for enclosures, diffusers and sample packaging inserts. Fast iteration for development and small batch.

Laser marking identification detail on metal lighting component.

LASER MARKING

Batch and prototype marking for identification, traceability and branding. Suited to pilot runs, sample kits and R&D assemblies.

Batch of CNC machined brass lighting canopies for architectural lighting.

CUSTOM LIGHTING

Machined lighting hardware, housings and heatsinks with optional LED integration. Serving architectural, horticultural and commercial lighting projects.

CNC machined prototype part with complex geometry for hardware development.

PROTOTYPING SUPPORT

CNC machined prototypes, sample builds and pre-production assemblies supporting validation before batch manufacture.

HOW WE MAKE PARTS

All imagery on our website shows genuine work produced in our Hertfordshire workshop. From prototyping through batch supply. No stock photos, just real machining, laser work and assembly.

THE KARPAS DIFFERENCE

We help engineers, designers and product teams get parts made quickly and reliably, with CNC machining, laser services and prototyping all under one roof.

From one off prototypes to repeat batches, we focus on communication, flexibility and building long term partnerships.

  • Send us your drawing or CAD file (STEP, PDF or DXF) and we’ll review it, ask any questions and come back with pricing and next steps.
    If you’re earlier in the process, we can help refine designs for machining or prototyping.

  • Yes, we make one off prototypes, sample builds and repeat batches. Many customers start with prototypes and later move into pre production and supply.

  • Timelines depend on complexity and quantities. Prototype and sample builds are generally faster; production batches can be scheduled. If you have a deadline, just let us know.

  • You’ll speak directly with the engineering team machining your parts, no account managers, no barriers. Communication is quicker and iteration is easier.

  • We machine in house in Hertfordshire and ship UK wide. Customers are welcome to collect if preferred.

  • Karpas Engineering is a CNC workshop in Hertfordshire supporting UK product teams, designers and manufacturers with machining, laser services and prototyping. We focus on fast iteration, consistent quality and clear communication, the things that make development and production smoother.

    We don’t overpromise. We make good work, help improve designs and keep things moving.

    We prioritise local sourcing, sustainable practices and long term partnerships. Capability matters, but service and reliability matter even more.
