What Makes Penta Different?
There are 3 key elements that run through the core of our company and staff at every level to ensure we deliver an exemplary service that goes above and beyond. We like to call these our 3 C's:
Focus on Quality
Impeccable quality is at the centre of our business.
All of our machined prototypes are subject to our rigorous inspection regime with designated inspectors, in-process inspection and a full final inspection completed on every part.
This gives us and you confidence that your delivered parts will be to your exact specification and meet the high quality standards to which we hold ourselves. Find out more about our commitment to quality.
CNC Machined Prototypes
We are happy to share our many years of prototype machining experience to help you achieve the best results in your projects.
We regularly machine prototypes and pre-production components in a range of materials including aluminium, stainless steel, engineering plastics, coppper, brass, bronze, tool steel and other ferrous and non ferrous metals.
Prototypes - CNC Milling
Our modern CNC machining centres and quick set tooling mean we can offer best value, even for prototype and pre production quantities.
We use our 10 seats of both 3D and 2D CAD/CAM software to respond quickly to tight deadlines.
We work with 3D models (.igs, .stp, parasolid, sat, sldprt, stl, and vda formats) and traditional 2D drawings (.pdfs, .tif, DXF or DWG files). We can also work from basic customer sketches or samples.
Prototypes - CNC Turning
Our fully integrated CAD/CAM system, modern CNC multi axis/spindle turning centres coupled with more traditional equipment means we can offer best value in all projects.
We have the capability to produce high quality prototypes using our manual and toolmakers CNC lathe.
