Through its immense experience and knowledge of the process, PTC has developed its own Rapidcast™ technology to overcome handling and other issues associated with production of castings from large patterns.
The process offers a cost competitive level for large 300 kg - 6000 kg parts. A minimum number of ceramic coats are applied within 48 hours, even for the largest of parts. The finished mould is strengthened and endures thermal and mechanical stresses associated with up to 6 MT of molten metal. This process is ideal for economical production of low volume, high precision, high integrity castings with customised design, metal alloy and contractions relevant to specific alloys, etc.
Key Benefits:
-
Ideal for After Market, Projects and Customised Parts
-
Extremely high and consistent dimensional accuracy
-
Exceptional surface finish
-
Optimised casting design – parting lines, cores and draft angles eliminated
-
Reduced casting weight – wall sections and machining allowances minimised
-
Consistent casting quality
-
Elimination of gas and hot-tear defects, and sand inclusions
For Serial Production:
- 100 to 6,000 kgs per piece
-
Low to medium volumes
-
Reverse Engineering & “Virtual Tooling” – offer short development cycles and reduced production lead times
Process Attributes:
- Since requirement for aluminium tooling is not cost effective for low volume production, this offers a more efficient solution
-
The polystyrene pattern produced using a die is replaced with a machined polystyrene pattern
-
A 7-axis robot is used for machining patterns with Virtual Tooling
-
This process is ideal for economical production of low volume, high precision, high integrity castings with customised design, choice of alloy, contractions relevant to specific alloys
-
Rapidcast™ offers all benefits of Replicast® process for even production of prototypes, spares or one-off parts
