Casting consistency ensures manufacturers of the high productivity expected from their machine investment. Holes Drilled holes can be held in tolerance with less run-off tendency because of excellent casting uniformity. This can reduce fixture costs, increase drill life, and provide significant design advantage in longer and smaller diameter holes and thinner walls between drilled passages. Design Consideration of the complete manufacturing process is essential in producing low finished cost components. Most permanent mold castings are highly machined.
Cost reduction comes from excellent machinability.
Casting design can eliminate machining operations. High casting integrity allows manufacture process design with fewer testing and inspection steps. Key to savings in these areas is an advanced joint design effort. Quality Quality to the customer is very high. Permanent mold gray iron castings are unique because imperfections tend to be external and detectable by visual inspection.
