Quality Assurance

Quality Assurance

Our injection moulded parts’ validation process evolved through our work with automotive OEMs. As a result, it reaches beyond the requirement of most other industries, but offers the reassurance of stringent quality protocols and a process that can be tailored to suit your component. We have found this method particularly useful for medical manufacturing.

During the Design for Manufacture stage of a project, a risk assessment of the product is performed and the outcome of this is formulated into an FMEA Process Flow flowchart, which will identify all potential failures in the design, manufacturing or assembly process.  Our objective is to eliminate these risks before production commences.


When the FMEA is complete, we develop bespoke test and gauge methods that will mimic the component’s intended use and/or assembly interfaces.  These tools are used by our quality engineers on the shop floor and our Metrology Department to check parts in the new project validation stage, and subsequently, each time they run in production.
