Rheomold Services – Casting
Manufacturing Simulations - Casting Simulations using Quick Cast
• Gravity sand casting
• High Pressure die casting
• Low Pressure die casting
Following direct improvements could be gained by Casting Simulation:
• Improvement of the casting quality by minimizing the entrapped air
• Minimizing set up time during the start of casting process
• Possibility to control HPDC machines more precisely
• Optimization of the whole casting process by
• Controlling filling with optimal plunger movement
• Shorter lead time during the tool designing process
• Less scrap and waste production when new design is taken on the use.
