01Why HY-TEK
Precision that fits, in parts and in partnership.
Look closely at the H in our logo. The crossbar is keyed into both uprights: separate parts, made to fit. That’s how we work. Components that drop straight into your assembly A, from a team that fits the way you work B.
-
Right first time
Every part is made with care and inspected before it leaves us, under a BSI-certified ISO 9001 quality system with full traceability.
-
One workshop, one order
Machining, grinding, EDM, fabrication and welding in-house, plus managed anodising, plating, painting and NDT. You receive a finished component, not a supply chain to manage.
-
Straight answers, quickly
Deal directly with the people who make your parts: clear quotes, realistic lead times and quick replies. Just ask our customers.
02Capabilities
Eight processes. One workshop. Your part, finished.
Up-to-date CNC alongside traditional manual skills, so every component is made the right way, whether it’s a single prototype, low-volume specialist work or a large production run.

-
01
CNC milling
Prismatic parts, pockets and complex features machined from solid, with repeatable accuracy from first-off to final batch.
-
02
CNC turning
Shafts, bushes, sleeves and flanges turned to tight tolerances, from one-off prototypes to production runs.
-
03
Manual turning
Time-served turners for prototypes, one-offs, repairs and modifications, where setting up a CNC program doesn’t make sense.
-
04
Manual milling
Fast, flexible milling for prototypes, modifications and short runs, by skilled hands on proven machines.
-
05
Cylindrical & surface grinding
Fine finishes and close geometric tolerances on shafts, bores and flat faces.
-
06
EDM (spark erosion)
Electrical discharge machining for hardened materials, sharp internal corners and features a cutter can’t reach.
-
07
Fabrication & sheet metalwork
Brackets, frames, guards and enclosures, cut, formed and fabricated to drawing.
-
08
Welding
Skilled fabricator-welders producing strong, clean welds on fabrications and machined assemblies.
Finished, not just machined.
We manage specialist finishing and third-party processes for you, so parts arrive ready to fit.
- Anodising
- Plating
- Painting
- Non-destructive testing
03How it works
From drawing to dispatch, without the chasing.
One point of contact, one order and one delivery, whatever processes your part needs along the way.
- 01
Send your drawing
A PDF drawing, a 3D model or a dimensioned sketch. Tell us the quantity, material and when you need it.
- 02
Get a clear quote
A competitive price and a realistic lead time. If something in the design will add cost or risk, we’ll tell you.
- 03
We make it
Programmed, set and produced in-house by time-served machinists, fabricators and welders.
- 04
We inspect it
Checked against your drawing with calibrated equipment, under our ISO 9001 quality system.
- 05
You fit it
Finished, documented and delivered, ready to go straight into your assembly.

04Industries
Made for industries that can’t afford a bad part.
Our customers work offshore, on the seabed and in the field. When a component doesn’t fit, a vessel waits, a turbine stands still or a machine sits idle. So we make sure it fits.
Subsea
Components for subsea exploration, trenching and cable-laying equipment, where there’s no popping back to fix it.
Offshore
Responsive machining and fabrication for offshore operations, from one-off replacements to repeat spares.
Renewable energy
Precision parts and fabrications for the renewables supply chain, made to spec and delivered on time.
Defence
Components produced under a BSI-certified quality system, with the traceability defence work demands.
Agriculture
Tough, serviceable parts and fabrications that keep machinery working through the season.
Automotive
Prototype and low-volume components machined to exacting standards.

08FAQs
Good questions, straight answers.
Can’t see yours? Call 01493 855345 or email hello@hy-tek.co.uk.
What do you need from me to quote?
Whatever you have: a PDF drawing, a 3D model or a dimensioned sketch. Tell us the quantity, material, any finishing or certification you need, and when you need the parts. If anything is missing, we’ll ask.
Do you take on one-offs and prototypes?
Yes. We produce batch sizes from a single prototype to much larger production runs, with the same attention to detail either way.
Are you ISO 9001 certified?
Yes. Our quality management system is certified to ISO 9001:2015 by BSI (certificate FS 621816), covering CNC and manual machining, electrical discharge machining (EDM), fabrication and sheet metal work. We’ve held ISO 9001 certification since 2015. View the certificate (PDF).
Can you supply parts finished and tested?
Yes. We manage specialist finishing and third-party processes, including anodising, plating, painting and non-destructive testing, so you receive a finished component, ready to fit.
Which industries do you work with?
Subsea exploration, subsea trenching and cable laying, offshore operations, renewable energy, defence, agriculture and automotive.
Where are you, and when are you open?
