Case Studies
CNC Machining of Large Hydraulic Manifold
The client required a large hydraulic manifold to be machined from a block of aluminium 1100 x 600 x 400mm. With the manifold needing to be machined to a high tolerance required by the client.
Electronics Enclosure
This case study was from a client who was very specific about the requirements for this electronics enclosure for the exact positional tolerances. It was a challenging job & one we completed to perfection.
High Precision Aerospace Fixture
The case study for this job was for an aerospace part that was no longer available to purchase. We had limited information to go on, but once again we finished this job to a very high standard.
Mechanical Prototyping of a Fishing Reel
The client for this case study had a new fishing reel concept that they wanted us to manufacturer so they could test it out before taking the design further.
