The creation of CLEANFLOW

SAVE WITH CLEANFLOW

“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”

Traditional casting issues

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, the idea


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.

CLEANFLOW KIT

The kit contains all the necessary elements for preparation of 20 cylinders of ø 100 mm

Kit contents

  • 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

OPERATION

STEP 1

Assembling the cylinder

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

STEP 2

Annealing

During annealing, thanks to the chimney effect, CLEANFLOW facilitates the flow of gas and waste generated by combustion of resin and wax

CASTING WITH

TRADITIONAL CASTING

STEP 3

Burnout

During annealing, thanks to the natural flow of hot air inside the cylinder, CLEANFLOW reduces burnout time up to 50%

TRADITIONAL CASTING

STEP 4

Injection

Very important:
the weight of the cylinder, concentrated on the cone only, ensures airtight lock.

It’s normal to have a space between the cylinder and the steel base.

Before insertion of the cylinder in the casting furnace, a metal base with a graphite cone will be positioned which will close the lower part of the cylinder.

ADVANTAGES

  • Increased casting quality

    Efficient resin combustion resulting in increase of casting qualities thanks to major reduction of waste residue

  • Additional savings

    Possible reduction of diameter and capacity of the central sprue that is part of the tree

    • Saving of metal quantity necessary for casting
    • Additional saving during refining of waste

  • Easy flow

    Easy flow of the combustion gas for improvement of casting quality

  • Typical workflow maintained

    Use of CLEANFLOW doesn’t require any substantial change from traditional casting techniques.

  • Reduction of burnout cycle

    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. 

    • 25% to 50% reduction of cylinder burn-out time
    • Substantial energy saving, proportioned to the reduction of burn-out time
    • Reduction of investment volume
