Lost foam means casting near the final contour with lost patterns made from expandable polystyrene (EPS). The EPS positive patterns are mounted to a casting system. The lost foam method is considered to be the most innova...

Precision machining combined with precision casting can be indeed considered as precision manufacturing. Though steel investment casting process is called as precision casting which indeed can obtained neat shape casting, however, ...

For the precision steel casting components, dimensional tolerances are selected by the designer or purchaser to make sure that the part can perform its function reliably and fit into its designed location. Assigning dimensions to a p...

Prepare for the pour. Clear out the aisle that runs along the oven and kiln. Place some sandbox sand on the concrete floor, about 1 1/2 ft wide, a couple inches tall, and long enough to easily place all the investments with a bit of ...
