Sand Casting - Gating Tiles

Overview - The flow of liquid metals in gating systems is in conformance with the laws of
 hydraulics. Research has shown that each portion of the gating system must be designed
 properly if the maximum benefits are to be obtained. It is imperative to realize that the
 ideal gating system should achieve the following:

    1) Decrease the velocity of the stream and thereby reduce the opportunity for
        dross formation;
    2) Minimize turbulence in the mold cavity
    3) Avoid mold and core erosion
    4) Deliver molten metal to the mold cavity in a manner that will establish the
        thermal gradients necessary to produce sound castings
    5) Increase the casting yield

Akron Porcelain and Plastics gating tile systems offers a wide variety of gating
components to address these issues to ensure a quality casting. The use of AP&P
ceramic gating components results in consistently better castings, elimination of
slag inclusions, reduction of rejects, and lower total cost of production.
AP&P gating components will neither erode nor spall in service at
temperatures to 3250 ˚F.

Akron Porcelain & Plastics gating components are used in all types and sizes of
today’s castings. A combination of lengths on gating tubes can be furnished to
eliminate most of the usual cutting. Akron Porcelain's staff work with engineers
and foundry personnel to design gating that will reduce the manual intensity
and improve flow of metal to ensure quality results and cost savings.
