Precision Machine


Hoppe Technologies provides customized, turnkey engineering support for our customers. We are committed to helping you enhance your designs for manufacturability – saving you time and money. Every part is processed using Solidworks® and reviewed by our skilled team of engineers before release to the shop floor and the highest standards of document control are always maintained.

In addition to our engineers, our programming team is another excellent resource. Utilizing Vericut® CNC simulation software, our programs are tested and perfected in virtual space before we begin machining parts – this ensures quality and predictability right from the start. As part of our programming process we use Mastercam.

We offer a full range of capabilities including:
  • Design for manufacturability
  • Manufacturing optimization
  • Statistical Process Controls
  • Concurrent engineering
  • Documentation that is compliant to our AS9100C:2009-01/ISO 9001:2008 standards
  • Process review prior to the release to the shop floor
Elastomer Moulding


As a complement to our world-class precision machining capabilities, we also have complex assembly and sub-assembly services available.
