At Pentagon Plastics we are fully accredited for the injection moulding of thermoplastic moulding materials within the scope of our ISO9001:2015 quality management system.

We provide components to a wide range of industry sectors and have purposely developed a robust and fluid quality system to align with specific customer requirements. Our process and procedures are controlled through internal and external audits maintained by our dedicated quality department.

We support a process of continuous improvement throughout the business with many initiatives being led by quality, as controlling the products we provide is a key focal point of the business.

The quality department are involved from a very early stage of production and provide First Article Inspection Reports (FAIR) at the initial sampling stage for new products. These documents form the basis for the bespoke Quality Plan that is created for all future production runs of these parts on approval from the customer.

On the start of a new production job our mould technicians will present a First Off sample to our inspector to gain approval before production can commence. During the production process the condition on the moulded part is monitored and recorded to ensure any production issues are identified and actioned in a timely manner. On the completion of the process last off checks are carried out to approve the parts before releasing the production to the next stage of manufacture. The first and last off samples are held within our quality department for future reference, until the next production batch is approved.

Inspection encompasses dimensional, visual and functional review of the moulded product and is supported with a range of measuring equipment that is calibrated on a routine basis. Standard measuring equipment includes micrometers, calipers, shadowgraph and specialised equipment with bespoke inspection gauges utilised when specifically required to maintain product quality.

Coordinate Measuring Machine

We have invested in a Coordinate Measuring Machine to help us maintain repeatability on dimensionally critical technical moulding. This provides our customers with the confidence that their production will be consistent, controlled and fit for purpose.
