Support Bracket for the Mass Transit Industry

At ProCIM we were recently contracted to fabricate a luggage support bracket by a customer in the mass transit industry. The support brackets would be installed in passenger rail cars. Our extensive mold making knowledge was leveraged to design a permanent cast mold able to handle the unit’s required A355 aluminum composition. Cimatron CAD software was utilized to design and modify the mold, which was then created with our advanced ZPS CNC machining center. H-13 hotwork die steel, hardened to 55 Rc was employed for mold production.

The machined casting was subjected to polishing and powder coating processes to ensure the molded part would exhibit the specified ultra smooth finish. A thorough inspection for quality and accuracy was carried out, employing visual and dimensional methods including portable Faro arm CMM and various standard instruments. We were able to achieve a tight tolerance of 0.001” on molding surfaces, with a 0.0005” tolerance met on sealing surfaces. The completed mold measured 5" x 15-1/2" x 27-3/4" when closed.

Measurements of the molded bracket were 3-3/8" x 7-5/16" x 19-7/8". Turnaround time for this project was 7 weeks, and this mold can produce 4000 aluminum support brackets annually.
