Shell Die Cast Spare Parts

Sand combined with a suitable binder can be packed or rammed rigidly about a pattern.

 

Benefits of Sand Casting

All ferrous and non ferrous alloys can be cast using the sand cast method: aluminum, brass, bronze, carbon steel, stainless steel, and irons both gray and ductile to name a few.Casting weight can vary from ounces to 50,000 pounds or more.Pattern costs are the most economic compared to other casting processes. Sand casting is usually the least expensive of all casting production processes.Quantities of parts produced can range from a prototype of one to thousands.Surface finishes of 250 RMS to 400 RMS.Painting, plating, anodizing and hard coat finishes can be applied to sand castings. The finish will vary according to the cast material.Cast letters, numbers and logos are possible with sand castings.

 

Production Speeds

 

Jolter Squeezer sand molding process can produce 12 molds/hour.Hunter Automatic (Horizontal Flask) sand molding process will produce 120 molds/hour without cores.Disa Automatic will produce 300 molds/hour without cores. Cores can be added, but please note that it will slow down the production process.

 

Sand Castings Pattern DescriptionSand casting patterns can be made out of wood (low volume), repro plastic (poured off of master wood pattern) & machined metal match plate pattern ( high volume).Sand castings can be a good solution for your casting needs whether the casting will need to be made of Aluminum, Brass, Bronze, Steel Alloys, Ductile Iron, Grey Iron & Zinc. Typically metal match plates are used for the high volume (Hunter & Disa automatic).Mold revision changes are relatively inexpensive for wood & repro plastic patterns. Below are 3 different processes, some sand casting tooling examples & tooling production machinery images to give you an idea of how the process is completed.
