Matchplate Molding Machine Designed for Jobbing Foundries.

Disa Industries, Inc., Oswego, Illinois, introduced the Disa matchplate molding machine, a new horizontally parted flaskless molding system for jobbing foundries. The molding system combines the vertical sand shot and squeeze with the horizontal molding techniques already familiar to smaller foundries.

The new matchplate molding machine produces green sand molds at a rate of 160 molds/hr (120 with core setting) with a maximum mismatch between cope and drag of 0.15 mm. Standard features on the system include a PLC to optimize the molding cycle, an operator video display unit, quick pattern change, computer integrated manufacturing technology to enable pre-programming of pattern data for error avoidance and time saving, chamber/mold blow-off, and in-chamber spray.

The new molding machine is compatible with other existing equipment and tooling. Its 20 x 24 in.-chamber allows the transfer of existing pattern plates without alterations. For example, a variable downsprue enables it to adapt to existing tooling using existing gating systems. The downsprue is fixed to the wear plate in the cope chamber from below. This means that it does not penetrate the squeeze plate and can be moved freely to accommodate different pattern plates.

The machine also offers straightforward maintenance, user-friendly operations and a clean and quiet performance. The first system went online in late 2000 at Benton Foundry, Benton, Pennsylvania.
