AQUAFLAME ININVESTMENT CASTING

Aquaflame machines are ideal for use in Investment casting wax rooms for a number of jointing and cleaning up operations. Use of a hydrogen torch allows a cleaner wax assembly leading to a reduction of inclusions in cast parts.

Use of a flame to clean up wax assemblies has a number of advantages over the current "hot knife" or "hot Spatula" systems. It generates much less smoke. Aquaflame melts the wax rather than burns it thus creating an improved wax room environment.

AQUAFLAME CAN PERFORM THE FOLLOWING TASKS:

  • Polishing complex investment casting wax models.
  • Flame polishing investment casting waxes - smooths the surface.
  • Clean up of wax assembly after investing with inclusive undercuts and smooths our rough areas.
  • Soldering and assembly of investment casting wax runner trees.
  • Melting and moulding of investment waxes.
  • Micro flame capability ensures that there is no damage to small delicate items like fine details.
  • Controlled localized heat source avoids melting items immediately adjacent to the work area.

THE SCIENCE BEHIND AQUAFLAME

Aquaflame uses the standard electricity supply to produce hydrogen and oxygen by the electrolysis of distilled water, such that the hydrogen can be burnt in the oxygen to produce a highly controllable and efficient high-temperature flame.

Aquaflame systems are used for welding, silver soldering, edge polishing of acrylic and other materials. The machine produces hydrogen and oxygen gases from water and electricity. The gases are mixed automatically to form a perfect, stoichiometric combustible mixture.

A single unit is capable of supplying one to four operators depending on the machine model selected. The gas goes through an atomiser unit containing liquid MEK (Methyl Ethyl Ketone). The MEK evaporates into the gas mixture altering the burning characteristics of the gas. The gas is delivered to the torch at low pressure where it is ignited to form a clean, highly concentrated flame. The flame temperature can be controlled by adjusting the amount of MEK vapour in the gas stream. The addition of MEK reduces the flame temperature and produces a larger, less intense flame. If the MEK is removed from the system, the temperature will increase to significantly higher levels. The torch valves allow the operator to independently adjust flame size and heat output.

Investment Casting Wax Assembly Clean Up.

There are currently three machines in the Aquaflame range. The Model 500 is used mainly by single users. The Model 800 is a two man machine whereas the Model 1200 is used in larger manufacturing setups and can support up to 4 users simultaneously. They are all high performance gas-generating units, producing a high temperature precision flame – in the range 1200-3300°C. Using a standard electrical supply, hydrogen and oxygen are produced by the electrolysis of distilled water such that the hydrogen can be burnt in the oxygen to produce a highly controllable and efficient high energy heat source.
