Are you looking for Lower cost parts with quick turnaround time?
 

Advantages of sand casting vs. machining a part from billet:

  • Quick turnaround time for sand casted parts
  • Sand casting provides for lower cost parts
  • Less machining time required with sand casting
  • Pattern usable for years. Up to 10,000 molds depending on tooling type
  • Near net shape parts
  • Less material waste with sand casting
  • Can incorporate a myriad of shapes and features with the use of sand cores such as holes, undercuts or zero draft
  • Loose molding of very limited usage parts available. Ask us for details
  • Lower start up cost than machining
  • Large selection of aluminum alloys
     

The Sand Casting Process:

The sand casting process has been around for several thousand years. It is one of the least expensive and fastest processes to get a product into production.

The sand casting process involves packing a specially prepared crushed rock, clay binder & water mixture around a pattern. (The patterns can be metal, wood, plastic or a combination of these materials).  The pattern is placed between two flask, (box), halves. A walnut shell parting dust is sprinkled onto the bottom half of the mold to keep the sand from sticking onto the pattern, then the bottom half of the mold is packed with the sand.  The sand is hand rammed tightly into the box half then a bottom board is placed onto it.  The box is rolled over and the process is repeated with the top half of the mold..  The mold is then squeezed tight  and the two mold halves are separated. The pattern is then removed from the mold.  A hole is punched into the top half of the mold to allow for the metal to be poured into the mold, and risers are also punched to adequately feed the casting to make the part solid and free from holes and voids. The sand casting process can then be repeated again as many times as is necessary to complete the parts necessary for the order. The casting tree is allowed sufficient time to cool and solidify, then the mold is shaken out to remove the packed sand from the casting tree. The casting tree is then cut, and the castings are separated from the gates and risers.  The castings are ground and finished per the customer’s requirements, and then shipped to the customer. 

Typical tolerances are + or - .030 for the first 12” and + or - .010 for each add. 3”.  Draft is typically 1.5 degrees per side and the minimum wall thickness is typically .170 depending on the surrounding areas and overall size of the part.sand castings, aluminum, aluminum castings, sand casted parts, heat treating, prototype castings, aluminum foundry, green sand foundry, flathead castings, castings, quality, foundry, commercial aluminum castings, aluminum foundry california, los angeles
