CNC MACHINING, PROTOTYPING &
SMALL BATCH PRODUCTION
Under one roof in our Hertfordshire workshop, we help UK manufacturers, engineers and product teams move from prototype through to pre-production and batch supply with in-house CNC milling, CNC turning, laser cutting and marking.
IN-HOUSE CAPABILITIES
From prototype parts to repeat small batch supply, our core in-house processes support product development, pre-production and ongoing manufacture.
Milled parts in aluminium, stainless steel, brass and engineering plastics. Including housings, heatsinks, brackets, mounts and development parts. Suitable for prototype, pre-production and repeat batch work.
Turned parts with milled features, threads and mounting details in aluminium, stainless steel and brass. Ideal for hardware, housings and repeat components from prototype through to batch supply.
Laser cut plastics and optical panels for enclosures, diffusers and sample packaging inserts. Fast iteration for development and small batch.
Batch and prototype marking for identification, traceability and branding. Suited to pilot runs, sample kits and R&D assemblies.
Machined lighting hardware, housings and heatsinks with optional LED integration. Serving architectural, horticultural and commercial lighting projects.
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.
Wireless file transfer for older CNC machines, without USB swaps. Helps keep programming fast and legacy equipment productive.
