Casting Set Cycle Time
Casting Set Cycle Time
Casting Set consists of three innovative iTherm® products:
iTherm® Piston
iTherm® Shot Sleeve
iTherm® Distributor
The SET is delivered as problem solving solution in cases where casting process is to be optimized and casting cycle shortened. FE simulation and optimization of casting process is performed by our engineers in the 5 STEP process. The SET guarantees required manufacturing tolerances and product performance, and as such is subject to our full warranty. Each of our Casting Set installed reduced the process cycle time by not less than 10%.
Shown below, an iTherm® Piston still in operation after 91,000 shots and 3x ring changes (every 30,000 shots).
Casting Piston Thermal Characteristics
Both iTherm® Piston and iTherm® Distributor are designed to permit complete thermal optimization of casting cycle and maximize productivity. They are manufactured using novel iMFT® technology.
A design-induced thermal phenomenon for triple benefit of iTherm® products:
(1) In pour segment the piston temeprature is higer compared to other pistons (low heat capacity of steel membrane) effect on quality of cast part.
(2) Extreme temperature drop occurs in pressurization segment (high piston cooling effectiveness) effect on cycle time.
(3) iTherm® piston has high in-service life (>50.000) (low transient stresses in the membrane) effect on durability.
Die Core In-service
Thermal assessment of iTherm® Die Core for automotive steering wheel housing is made during operation using IR camera. Pictures at left side show temperature at core surface (a) at cycle finish and (b) before start of a new cycle. The core surface temperature is around 100oC lower compared to surface temperature of conventional die core (IR pictures at the right side). In addition to considerable influence on cycle time (a 20% improvement), there was an important influence on part quality.
