We always refer to Urethane or Vacuum casting when there are cost or lead time constraints for prototyping. We deploy different materials like ABS and polyutheranes in the casting process. Although it might depend on the volume and other specifications yet a minimum of 12 parts can be processed within 20 days. Through this, almost a range of accuracy of around ± 0.3% mm is achieved when the dimensions are smaller than 100mm. 0.75 mm is the least needed thickness for walls but it can go as thick as 1.5 mm for getting more strength in the design. We have helped many automotive companies to make impressive prototypes in the automotive industry.
