Aerospace Sector

Hirsh has a long history of supporting the industrial, automotive, aerospace, medical device, biotechnology, and scientific instrument sectors. 

General tolerances on metals can be held to +/- 0.005" (+/- 0.127 mm) in accordance with ISO 2768 unless otherwise specified. Plastics and composites can be +/- 0.010”.

Hirsh can also machine and inspect to tight tolerances, including sub +/- 0.001" tolerances, per your drawing specifications and GD&T callouts.

Yes, in fact, it’s our team’s preference that we support your part’s production with DFM before moving into production.

Our DFM is most effective when it’s requested before a design is finalized. We can still provide design optimization feedback even after a design has been finalized, though. Contact our team as early in the manufacturing process as possible to achieve the biggest time and cost savings.

Easy! Just submit an RFQ through our website. 

We accept STEP, STP, SLDPRT, IGS, X_T, PDF, JPG, and PNG file formats.

For the fastest turnaround time on quotes, please include both a CAD model and a detailed, reviewed technical drawing for each part that you want quoted. This enables our team to build a comprehensive quote and move into production as quickly as possible.

Milling: 3-, 4- and 5-axis CNC milling options for your most complex and intricate components

Turning: Swiss and multi-turret turning centers with live tooling and barfeeders to support lights-out production.

Flexible Manufacturing Solutions: two Fastems systems, seven 5-axis mills and over 100 pallets to support production in the 100s and 1000s; reduced setups and shorter cycle times improve quality and cut down on costs.
