Precision Aviation Machining: Are You Paying Over The Odds?

precision aviation machining

Precision Aviation machining carries a fairly unique set of manufacturing responsibilities in terms of quality, timely delivery and accountability, but are you paying over the odds for your aviation components, parts or sub-assemblies? Recent years have seen some great machining breakthroughs, manufacturing innovations & technological manufacturing improvements but all of these count for little unless the benefits of these high tech solutions are not fully integrated into a company’s overall manufacturing philosophy.

AS9100 Precision Aviation Machining

Quality control is top of the agenda within the realm of precision aviation machining, and that’s why aerospace and aviation safety is constantly improved across the board, from design to manufacturing to installation to maintenance – the implications of getting it wrong are too grave to imagine. But within this area of focus, are your precision aviation machining contractors producing quality components via true 21st century ‘lean manufacturing’ principles? AS9100 certification for Aviation, aviation, space and defence – now in revision C, sets productivity, safety and reliability guidelines into place to oversee quality management systems and process control for high quality output within a lean manufacturing framework.

SC21 Precision Aviation Machining

Precision Aviation Machining – also spanning defence and security sectors, traditionally attracts red tape like nothing else, but in recent years it has been recognised that in order to keep manufacturing costs minimal and quality of output high, there is a requirement for optimised supply chain management. Welcome to the stage, SC21 – 21st century supply chain management – a supply chain initiative that looks at cutting unnecessary red tape, nurturing relationships, streamlining of processes and a leaner, higher quality manufacturing philosophy with real-world results.

Running 24/7, maintaining AS9100 (c) certification and signatories to the SC21 Supply Chain initiative, Di-Spark Ltd are a 21st century precision aviation machining company.
