With tooling development complete or the use of existing tooling, the process is off and running.
We employ three types of Green Sand molding machines, including Automated matchplate 16x20 (above & left), Jolt Squeezer, or Rota lift molding to produce quality castings.
As needed to lighten or create a passageway within the casting, shell or sodium silicate cores are used. Cores are made on fully automated core machines.
Robotic pouring assures the tranquil filling of both the ladle and the mold on our automated molding line. This enhances the metal quality and the overall quality of your casting.
To maintain melt quality, specific alloys are melted in clean electric resistance furnaces with digital temperature control.
Melt quality is monitored by reduced pressure gas testing to verify rotary degassing, and thermal analysis to verify grain structure and modification of alloys.
Attention to detail is the responsibility of all associates.
Prior to final inspection parting lines are removed and castings are shot blasted to blend the overall finish. Castings are inspected prior to packaging to insure that our customer requirements are met.
For repeatability, process sheets (above) are used through out the casting process. Each part has a mold file with all pouring parameters to ensure quality castings.
To continue melt quality, spectrograph analysis (above) is used as a process check tool for casting certifications.
