Electro-magnetic, low-pressure molding
This process - which is proprietary to Alcast - removes much of the margin for error or variation in molding. Through our electric melting and molding process, oxides are filtered out and much of the turbulence common to traditional pouring is eliminated, which produces a porosity-free casting that's less likely to crack or warp. And because it's an automated and controlled process, we can ensure consistent results.
Characteristics of Alcast Process
- Electro-magnetic, low turbulance, bottom-fill pouring
- Electric melting
- Argon metal cleaning and de-gassing
- Double ceramic filtration to further remove oxides
- Four temperature control zones between melter and the mold
- Detailed set-up and process specifications for each job
Benefits of Alcast Process
- Excellent Integrity
- Complex geometry and coring
- Excellent surface finish
- Consistency
- Moderate tooling costs
- Suited for wide range of volumes
- Low Scrap Rate, One Percent or Less on Raw Castings
- Pressure Tightness
Core Making
One reason Alcast is able to routinely produce complex castings that other foundries find difficult is our willingness to take the extra steps needed to ensure quality. An example is our use of very fine shell sand in our cores, which results in a completed casting that exceeds surface specifications and requires less post-finishing.
Castings produced with our process can be heat treated, painted, polished, chrome plated, chromated, or anodized
