Permanent Mold Casting

The Electric Materials Company (TEMCO) has been providing quality copper castings for over 90 years. As an organization which has continually expanded its capabilities through investment in people and equipment, we have developed into a diverse and vertically integrated manufacturer. In addition to our copper foundry capabilities our services also include extrusions, forgings, fabrication, machining, brazing, commutator manufacturing, AC rotor manufacturing, heat treating and electroplating. Our trained craftsmen are knowledgeable in metallurgy and take great care in proper permanent mold preparation and melting practices ensuring optimal cast results.
 
Advantages of Permanent Mold Casting
  • Design flexibility
  • Superior surface finish compared to sand castings
  • Tighter tolerancing
  • Costly machining operations are often eliminated
  • High Conductivity
  • Automated molding equipment provides improved melt flow and solidification
  • Excellent product uniformity and repeatability
  • Near net shape capabilities
  • Thinner cross sections available than by other casting methods
  • Rapid solidification yields uniform fine dense grain structure
  • Improved mechanical properties
  • High quality
