Rapid Prototyping
We have improved our rapid prototyping service by investing in a new Dimension 3D Rapid Prototype printer. We can now shorten the design and development cycle by making useable parts in days, sometimes even hours. See our Services page for more information.

Welcome to Miniplas Limited
We provide a competitive injection mould making and injection moulding facility, offering speed and flexibility in producing small precision plastic mouldings, in quantities to meet any customer requirement.

The company was established in 1971, moving to our fabrication facility and moulding tool shop, located in Welwyn Garden City, Hertfordshire, in 1980. We now occupy a total of 500 square metres, dedicated to precision plastic injection moulding and plastic injection moulding tools.

Starting from small beginnings, our tool room now has 3D machining capabilities and CAD/CAM facilities. All tool design and production is carried out in-house reducing the time from tool completion to the finished moulded part. We are very responsive to any minor modifications. This means that modifications required during tool trials can be carried out immediately, and any further changes, or customer specified modifications, are made with a minimum of downtime.

We use modern microprocessor controlled plastic injection moulding equipment to produce high quality component parts for a varying range of different markets, inluding telecommunication, medical, healthcare, electronic and document transfer industries.

Our management system is approved to BS EN ISO 9001:2008, which ensures that we maintain a close control of production at all stages.
