To compete with its diecasting competitors in England, Europe and South Africa, Riverside must keep mold shift
Brantford, Ontario, Canada, the world's largest manufacturer of exhaust manifolds for passenger cars and light trucks, was experiencing mold shift
on their existing molding machines at its Wingham, Ontario, Canada facility.
The variable squeeze pressures allow for the production of harder molds, and the machine incorporates new technology in the squeeze station to reduce mold shift
In green sand casting, one big thing we look at is eliminating mold shift
The machine also incorporates new technology in the squeeze station to reduce mold shift
For WAFCO, one of the key decision makers for the new" system was zero mold shift
Summit Indexing Mold Handlers promote gentle mold movement without mold shift
through the use of Hydro Proportional Valves and oversize Shock Absorbers to decelerate moving molds.
One of the keys to the mold handling system is its ability during indexing to promote gentle mold movement without mold shift
through the use of hydraulic shock absorbers and ultra high density polyurethane.
We have been able to virtually eliminate mold shift
, due to the positive flask alignment and mold stripping design, along with crush and sand inclusions that are normally associated with shift.
The system has allowed the foundry to achieve more than a 90 mold hardness consistently across the cope and drag, improving the casting finish, according to Grenier, who added that the foundry has seen no mold shift
on the system, leading to the better quality finish necessary for the firefighting equipment castings it produces.
The type of closure device and lineup system is critical to keep from knocking sand into the mold, crushing cores, preventing runouts and minimizing mold shift
To prevent casting defects due to mold shift
and core crush, it was found that the pins and bushings should be replaced at or before this point is reached.
