Superiors Quality Policy

“Satisfying the customer by providing a quality product, delivered on time, while promoting a stable workplace and continually improving our processes and products”

Inspection Systems

At Superior, both ISO 9001 and AS9100 certified, provides the high level of quality that aerospace and defense manufacturers need, without exception. We do this with a keen focus on quality metrics. Superior utilizes Statistical Process Control (SPC) methods to ensure that our facility operates at peak production without being over extended, and the result is a Parts Per Million (PPM) well below the industry average.

We also ensure quality by employing experienced quality personnel, through automated inspections, and utilizing CNC Coordinate Measuring Machines (CMMs). All of these things help us limit wasted time and materials, which adds up to effective cost control for you, our client.

Of course consistently producing quality aircraft components is about much more than cost control – it’s about limiting your risk. We do this by being AS9100 and ISO 9001 certified. Maintaining these certifications ensure that our facility and practices meet comprehensive quality standards. Everything from our inspection and testing procedures to our product documentation has to meet stringent requirements for us to keep our certifications.

Being certified also ensures that we’re capable of certain quality controls like lot traceability and internal audits. Ultimately, these certifications are a hallmark of our quality as an aerospace manufacturer and indicate that we are company that can be trusted.

ITAR and Export Controls

When manufacturing components for defense projects, accuracy, process control and documentation are essential. At Superior, we have the experience, certifications, staff and equipment required to competitively produce critical aerospace parts on time.

We are an ITAR registered aerospace manufacturer an capable of producing USML controlled defense and military aircraft parts and providing material and lot traceability, including DFARS material controls. To ensure we provide this precision, our facility is certified for both AS9100 D and ISO 9001:2015.

We have an experienced quality control team that is familiar with a variety of defense and aerospace manufacturing requirements, including DX and DO defense contract requirements.

We also utilize SPC for many of our quality and performance metrics, including a temperature controlled quality room with multiple fully automated CMM’s (coordinate measuring machines) to ensure accurate measurements.

Customer Approvals

Superior is approved by most major aerospace companies and maintains excellent supplier performance ratings. We take pride in not only delivering a superior product, but delivering it on time and at competitive prices.

Lean Manufacturing

At Superior, we have significantly reduced waste to improve overall efficiency and streamline our globally competitive processes. This involves highly automated “lights out” machining, dedicated fixtures to minimize set-up time, 5S compliance company-wide, Poka Yoke mistake proofing, and detailed process controls.
