Precision CNC machining for parts, moulds and production runs
From a single prototype to repeat production, Delta Rubber machines complex components in steel, aluminium and engineering plastics, with tooling and quality control under one roof.
What is CNC machining?
CNC (Computer Numerical Control) machining uses programmed tools to remove material from a solid block. Every movement follows exact instructions, so the hundredth part matches the first.
Milling is the process we use most: rotating cutting tools shape metals and polymers into finished geometry with tight tolerances and a clean surface finish. It suits industries where reliability and durability are not optional.
Because we also make rubber mouldings, we understand what a tool has to withstand. That experience goes into every part we cut.
Our capabilities
What we machine
A full range of CNC services, managed from design through to finished, inspected components.
CNC milling, 2D and 3D
Pockets, profiles, contours and complex 3D surfaces cut from solid stock in metals and plastics.
Prototypes and batches
Production milling
Repeatable runs with fixed set-ups and programmes, so lead times and quality stay consistent.
One-off to repeat orders
Mould manufacturing
Steel and aluminium moulds designed and machined in-house to your mould specification.

Why Delta Rubber
Why businesses choose us for CNC machining
Experienced team
Years of hands-on machining and precision engineering experience behind every part.
Modern equipment
CNC systems capable of complex shapes with accuracy, repeatability and efficiency.
Tailored to your project
Prototype or large-scale production, we work closely with you on a customised solution.
Quality assurance
Strict quality control from material selection to final inspection.
What materials can you machine?
We work with a wide range of metals and engineering plastics. Tell us the application and we will recommend a suitable material.
What are your minimum order quantities?
We take single prototypes as well as production runs. Send your requirement and we will quote accordingly.
What files do you need to quote?
A drawing or CAD model is ideal. If you only have a sample part, we can work from that.
Can you machine moulds as well as parts?
Yes. We design and machine steel and aluminium moulds, and repair or refurbish existing tooling.
How long does a job take?
Lead time depends on complexity, material and quantity. Your quote will include a confirmed turnaround.
