Investment Casting Series

Investment casting is an industrial process based on lost-wax casting, also called High Precision Casting. Compared with sand casting, the precision of products is higher, the surface is smoother, and the subsequent processing is also less. This process has advantages in producing precise and complex products.

  • “When I first cooperated with WTM, I just started the import business. Before that, I found many suppliers on the Internet. Their prices were very attractive, but the products they received were a pile of garbage. Later, I met Linda, who gave me a lot of professional advice, which made me avoid many detours and able to tolerate my bad temper. Once, I lost my temper when the port could not pick up the goods normally, but Linda kept looking for solutions. Finally, she successfully picked up the goods and saved the loss. Now she is not only my supplier but also my good friend!”

What are the Advantages of Lost Foam Casting in Production of Electric Shovel Bucket Teeth?
Caterpillar interchangeable series bucket teeth are key components on open-pit coal mine electric shovels. Single cast part weighs 135 kg, made from ZGMnl3 material. The traditional casting process for such parts usually involves a complex workflow with multiple sand cores, time-consuming, and requires a high standard of operation from the workers. The final product often has rough edges, which are difficult to clean up, contributing to a high reject rate. The lost foam casting process presents many technical and economic advantages to address these issues.

 

Here are some of the key benefits to consider:

 

  1. No need for a core, eliminating the core-making process and relevant machinery.
  2. No parting line, no core print gap, hence no rough edges or burrs on the castings.
  3. The requirement for mould draft and other crucial parameters, such as negative parting line and negative core values, can be reduced or even eliminated, enhancing the precision specifications of the casting.
  4. The polyurethane foam mould is easy to bond and assemble.
  5. Better working environment and lower production costs.

 

To fully leverage the advantages of the lost foam casting process and improve the output rate, a cluster casting method can be used to forge the bucket teeth. Using bottom-pull negative pressure sandbox, ten pieces can be placed in one box, with the tip of the bucket teeth facing downwards, placed parallel within the sandbox. No sprue is necessary due to the use of a closed casting system.

 

When pouring, the riser is filled first and then swiftly and steadily filled until molten steel fills the sprue from start to finish. The EPS (Expandable Polystyrene) in the direct sprue vaporizes quickly and the space is filled with molten steel in a short time. This not only effectively prevents the vacuum from drawing gas into the mold but also creates a certain static pressure in the casting system. Thus, preventing gas inclusions and sediment during the filling process and averting defects such as gas holes, shrinkage, etc., while also avoiding waste caused by box collapse due to the casting.

 

The casting obtained by lost foam casting has good molding, geometric specifications completely up to standard; the casting has good process properties, no burrs, no shrinkage, shrinkage conditions, no feeder head; reducing labor such as cleaning and laser cutting by 50%. The yield of the casting is more than 40% higher than that of the traditional sand mold casting.
