Quality Control

All of our quality assurance programs are in accordance with ISO standards and we are working toward full certification.

  • Inspection procedures are implemented to ensure quality of all products manufactured.
  • All inspection and measuring equipment is calibrated on a continual basis.  Records are available for review upon request.
  • Full material and process certifications are kept on file. They are also included with the order shipment when requested.
  • Outside venders are audited annually to ensure quality. Outside processes include heat treatment, plating, painting etc.
  • Unless otherwise specified, we keep our customer’s records indefinitely.   This ensures a full history of each part. 
  • All material is DFARS compliant.  Since most of our customers require thier parts to be manufactured using DFARS compliant material, we have made it policy that all material purchased is DFARS compliant.
  • Peninsula Spring practices a Copy Exact program.  This assures consistency with repeat orders.

Our quality plan provides our management the proper criteria in which to guide the establishment and implementation of a total quality control program. It is designed to show the tasks and procedures for implementing military specification MIL-I-45208A.
