Once your initial design is drafted, raw prototypes can be produced for evaluation and development prior to any final finishing being undertaken.

Prototyping and Development

Production from 5 off to 5000 off is economically achievable using the latest CNC technology.

Our machines are capable of having converted data, from AutoCAD and SolidWorks, directly imported into them, thus reducing machine downtime keeping costs to a minimum.

Production Manufacturing


Assisting in the designing of your product from your concept, we can assist with the aid of CAD technologies.

Assisted Design Service

We strive for perfection, with rigorous inspection procedures and a high standard of quality control.

All components go through inspection procedures both during production and final finishing.


Our management systems enable full traceability of all components. We are able to offer Cerificates of Conformity and Mill Certificates when requested.

Management Systems

We undertake many final finishes on components, including zinc plating, alochroming, anodising, powder coating, stove enamelling, silk screening and engraving.

Component Finishing


Established in 1964, I.M.P. has provided both a local and national manufacturing service, specialising in Precision Quality sheet metal components for a diverse range of uses. We have accommodated the requirements of many businesses including the Electronics, Optical, Medical, Research and Construction Industries.

In the true tradition of family owned and operated companies, we at I.M.P. provide a rapid manufacturing base with all those sought after values of Service, Commitment and Quality



Since moving to our new larger 5000 sqft ground floor premises in 2012, we have had the opportunity to purchase larger and far more versatile machinery. In 2015 with the addition of a new punching machine, software was introduced to enable the converting and importing of .dwg, .iges and alike files. We have now streamlined the production of work and undertaken work previously uneconomical.

The company's next progression is the acquisition of a new CNC pressbrake to introduce greater versatility of components manufacturable.
