Precision Ceramic Leachable Cores

Leachable Cores

AKRON Porcelain & Plastics Company’s advanced technology and experience with Ceramic Injection Molding capability has the following advantages:

  • Zircon and fused silica compatible
  • Small and large standard and custom shapes
  • Leachable ceramic formulation easily removed via a Kolene-based system
  • CAD design and engineering assistance
  • Affordable single and multiple cavity custom tooling with short lead-times

Bottom Fill Pour System

AKRON Porcelain & Plastics Company’s engineering designed this unique concept to assist foundries on difficult parts with the following advantages:

  • Reduce pour turbulence and scrap
  • Multiple pours
  • Consistent fills achieved without modifying current shell and pouring procedures
  • Impurities are trapped above the pour, reducing defects and improving surface quality
  • 1.8″ OD x 1.3″ ID Tube with lengths ranging from 14″ to 22″ (Place 1/2″ from shell bottom)
  • For optimal performance, pre-heat BFPS to 1800F
  • Available in Mullite, Cordierite, and Fused Silica

Gate Tubes

AKRON Porcelain & Plastics Company’s thin wall gate tubes are exceptionally lightweight due to a 3/8″ wall thickness, thus reduced shipping expense and easier to handle. Tubes lengths are furnished in 1/2″ increments and longer than 18″ up to 40″ can be manufactured upon request.

  • Plain End Tube: Can be furnished with one or both ends angled.
  • Matching End Tube: Eliminate the use of sprue stick and guarantee that the effective diameter of the sprue and gating system is maintained.
  • Bent Tube: Replaces the horn gate for bottom poured castings.
  • Smashed End and Slotted Tube: Custom design to accommodate process.
