Customer Communication

In accordance with our commitment to exceed our customer’s expectations, Custom Components & Assemblies, Inc. highlights effective customer communication as an essential element of delivering customer satisfaction.

Products and Services

The monitoring and measurement program for all precision machining products is defined in drawings and specifications, production routers, purchasing documents and in inspection and testing procedures.

Verification of Purchased Products

All purchased products are subjected to a visual inspection by the receiving inspector. Designated products are also subjected to a more detailed and technical quality control (QC) inspection.

In-Process Inspections

In-process inspections are in the form of first article inspections and operator inspections to ensure our quality and the on-time delivery of completed orders to our customers.

Final Acceptance Inspection

Finished CNC machining products are subjected to the final QC inspection. First, inspectors verify that all specified and in-process inspections have been completed. Then they perform the remaining inspections and tests necessary to complete the evidence of product conformity. Results of all inspections and tests are recorded and only products that pass the final inspection process are packaged and shipped.

The conformity and effectiveness of our quality management system is monitored by internal audits and by measuring quality performance and customer satisfaction.
