Quality Assurance

To demonstrate our ongoing commitment to quality, cost-effectiveness, and continuous improvement, TPC  Manufacturing has achieved Nadcap accreditation in several special process categories. Nadcap certification is an important way of communicating to our customers that we excel at manufacturing products that meet or exceed the high quality standards established for the aerospace and defense industries.

 

Nadcap is a global cooperative accreditation program that provides independent certification of special manufacturing processes for the aerospace engineering, defense, and related industries. Its membership brings together technical experts, prime contractors, suppliers, and government representatives who work together to define operational requirements for special processes and establish a standardized approach for supplier audit and approval.

 

We sought Nadcap Certification in an effort to develop cost-effective processes that strengthened the quality of our products while giving our customers increased confidence in our capabilities. As a major provider of complex components and assemblies used in aircraft, power generation, and marine turbine engines, our status as a Nadcap accredited supplier assures customers that work is performed competently and consistently. It also highlights our commitment to quality and continuous improvement, reinforced by our certifications.

 

The scope of our accreditation covers non-destructive testing, non-conventional machining, heat treating, and vacuum brazing. Achieving certification in these four special process categories was an extraordinary accomplishment for our team. With this level of technical authority, our turnkey solutions for OEM turbine engine customers lead to superior quality, lower costs, and greater innovation.

The Quality Tools We Use

Quality Tools are used to help identify causes, understand processes and to collect and analyze data to be able to make informed decisions. Some of the quality tools used at Hi-Tek Manufacturing include, but are not limited to:

• Process Capability (Cpk) and Process Performance (Ppk) Studies

• Histograms

• Stratification Diagrams

• Scatterplots

In process improvement efforts, the process capability ratio is a statistical measure of process capability, i.e. the ability of a process to produce output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control.
