The single cell die oven, which was such a huge advance over the chest oven just, isn’t good enough any more. Since its introduction thirty-odd years ago, the SCDO has remained relatively unchanged. There have naturally been incremental improvements but these haven’t nearly kept pace with the demands of today’s marketplace.
- Die to be equal to billet temperature for the first push, minimizing break through pressure enabling the use of high performance dies, reducing die breakage and eliminating start up billets.
- Minimize die bearing oxidation and nitride layer degradation responsible for surface defects on the profile, shorter die life, and reduced die knock-off.
To heat the die uniformly to within +/- 5C (10F) of billet temperature in the minimum amount of time without over heating and softening the die steel or damaging the nitride layer on the die bearing.
Benefits of the Castool Die Ovens
- No billets wasted and scrap produced by ensuring a die is brought completely to optimum operation temperature.
- Avoids the use of higher temperature first billets.
- The die is individually heated completely and uniformly to operation temperature so rapidly, that oxidation of the bearing is minimal, and bearing surface integrity is maintained to ensure optimum extrusion surface finish.
- Extrusion weight consistency (lbs/ft or kg/m) is improved by quickly reaching steady state thermal conditions.
- Dies are positively protected from overheating.
- Colored lights indicating the heating status of the dies. When the heating cycle starts, a yellow indicator light comes on. The controller shows “Time to temperature,” and begins to count down.
- Single cell ovens save money
With the Castool Superoven, Castool again sets a new standard of excellence in the extrusion industry. Results may vary depending on individual press characteristics and setup.
