“Through the chimney effect, CLEANFLOW allows an easier and natural flow from the top of the slags and combustion gas caused by wax pouring, resin burning or use of similar materials for the creation of the tree”
The quality of traditional casting and proto-casting is one of the most common topics in the jewelry sector.
In lost wax casting it’s hard to maintain a constant quality of the product.
In casting with systems printed with 3D technology resin, on the other hand, a discrepancy can be noticed among the types of resins with different melting points and different geometries.
CLEANFLOW goal is to stabilize and significantly improve these and other aspects.
CLEANFLOW is a kit created to support the preparation process of casting cylinders. It’s been developed to improve the flow and the burning phase of the tree material during the burnout cycle.
The principle on which it is based reduces considerably the problems due to slags inside the cylinder and combustion gas bubbles that struggle to exit with the traditional system.
Perforated lid for the centering of the sprue and creation of a second hole in the investment cover
Heat-resistant conic-shaped cap and C-Clip to seal the second hole at the bottom of the cylinder during metal pouring phase
Steel base to support the heat-resistant cone for the correct positioning at the bottom of the cylinders
Seal to cover the upper part of the cone for greater resistance
The lid creates the marks on one face of the investment to open the chimney and to make clear which part of the cylinder goes on the bottom in the casting machine
During annealing, thanks to the chimney effect, CLEANFLOW facilitates the flow of gas and waste generated by combustion of resin and wax
During annealing, thanks to the natural flow of hot air inside the cylinder, CLEANFLOW reduces burnout time up to 50%
During metal injection, the graphite cone with seal, put on a steel base, will ensure airtight lock of the hole at the bottom of the cylinder.
Efficient resin combustion resulting in increase of casting qualities thanks to major reduction of waste residue
Possible reduction of diameter and capacity of the central sprue that is part of the tree
Easy flow of the combustion gas for improvement of casting quality
Use of CLEANFLOW doesn’t require any substantial change from traditional casting techniques.
The burnout cycle is reduced due to heat flowing through the vacuum created by the cylinder - which has holes at both top and bottom. This chimney-effect creates a much faster, more efficient burnout.
