Tooling For Every Application
From Military vehicles to sugar cane harvesters to this tool used in forming corrugated plastic. Nohr Pattern can build tooling for almost any type of application. This is CNC machined from a solid block of aluminum.
We recently received an order to make tooling for this impeller, but our customer only had a drawing. We made a 3D Cad model using SolidWorks2016 and generated toolpaths for our CNC.
Once the pattern and core box were cut we rigged them to run at the foundry. The core box needed vents because that core was blown.
At the foundry they made a sand mold of each half of the pattern and the cores were made and set in the mold to form the interior passages of the casting.
Once the molds are closed the castings are poured, after cooling they are shook out, ground, and shot blasted to give it a nice surface finish. Our total timeline on this part was less than 2 weeks from receipt of the drawing to finished casting. The foundry only made one so we can provide a dimensional report to their customer for approval before running the balance of the order.
What our customers say about our work…
Quote from an Oil & Gas Customer Jim, Hope this email finds you well. I just wanted to share a compliment with you regarding some of our patterns that you produced. The two foundries we just finished on site audits with spoke highly of your patterns and the quality in which they are manufactured. I…
