Machined Uplock Support

  • No-bake sand casting is a cost-effective method for producing large, complex structural aluminum castings.
  • Close collaboration and communication between casting and OEM engineers are essential to develop a casting design which meets performance and quality standards at a reasonable cost.
  • Vertically integrated in-house manufacturing (patterns >> molds >> casting >> heat treat >> machining) offers process control benefits, integrated design and lower total manufacturing cost.
  • "No-weld" regions need to be designated with due diligence, because unnecessary restrictions raise scrap rates and increase production costs.
