Consider a Precision Plastic Machined Component in your Design

Many efforts have been undertaken by OEMs to remove costs from their products. Converting metal components to plastic components in an application can result in significant reductions in costs, design changes, overall weight and waste.

We are committed to quality at every step of the plastic component machining process. Our precision plastic machining facility is registered under following quality certifications:

  • ISO 9001:2015

  • ISO 13485:2016

  • ITAR registered

  • REACH and ROHS compliant

With a state-of-the-art temperature controlled metrology lab, we employ the following tools and processes to ensure the highest quality:

  • Nikon vision systems which are programmable visual inspection devices that ensure that the act of measuring features for inspection will not alter the product itself

  • SPC analysis and process optimization

  • Toolmaker microscopes which are used to measure dimensions and angles of machined metals.

We are a certified or premier supplier for over 30 companies, including scientific instrumentation, medical devices, and the nuclear industry. We consistently ship large quantities of finished components – dock to stock – with no quality rejections.

Potential or existing customers should feel free to request quality information or arrange for a quality audit. We are happy to provide a copy of our quality manual for your review.
