Quality Sheet Metal Products to ISO 9001

In order to continually meet the requirements of ISO 9001, metal fabrication supplier Hydram operates fully documented Quality Procedures and a Quality Manual.  To support these, the company employs a dedicated Quality Team consisting of a Quality Manager, two Quality Engineers and five Quality Technicians, assisted by Project Engineers as required.  The team undertakes all aspects of quality assurance and inspection, utilising both traditional and state-of-the-art precision measuring equipment from a dedicated office.  Full dimensional inspection reports suited to specific customer requirements are provided, working to formal processes such as APQP and PPAP if required.

New Product Introduction

As a minimum, all new sheet metal product introductions are handled by an NPI project group consisting of members from Quality, Production and Commercial teams, and headed by a Project Engineer.  The NPI group meet before the production process begins to ensure that the bills of material, routings, drawings and production information are all accurate and provide sufficient information to production operators.  The Project Engineer then follows the pre-production and first production batches through to completion and ensures, with the assistance of the Quality Team, that all metal fabrications are produced precisely to the customer’s requirements first time, recording any detail changes on the production system for future batches.

Shopfloor Quality Control

Shopfloor inspection is the responsibility of all operatives and is carried out in line with the appropriate Quality Plan, plus supporting documentation, at each stage of the production process by trained personnel.  A dedicated inspection area carries out final inspection on critical features supported by automated vision systems.
