D6 Pneumatic Tamper for Large Casting Sand Molds and Construction Product overview A heavyduty pneumatic tamper designed for tamping large casting sand molds, compacting concrete and bricks, and molding mediumsized castings. Built from cast iron for long service life, the D6 delivers impact tamping with low air consumption for continuous operation. Key benefits Durable construction: Cast iron body resists abrasion, corrosion, and temperatures while maintaining structural integrity under repeated impact. Fast and efficient tamping: Operates at an air pressure of 0.63 MPa with an impact frequency of 700 Hz to complete tamping tasks quickly. Low air consumption: Uses 0.45 L per second 0.11 gal per second for extended runtime with typical compressed air systems. Easy to operate: Simple trigger handle starts the tamping action; suitable for users with minimal training. Maintainable design: Replaceable sealing ring and straightforward access to wear parts reduce downtime. Typical applications Foundry work: Compacting large sand molds and tamping mediumsized casting molds prior to pouring. Construction site use: Pounding and tamping concrete and bricks for foundations, walkways, and precast elements. Smelting and solidification: Assisting sand compaction and mold preparation in metalworking operations.
