Aluminum Tooling & Jig Plate

Aluminum plates used for tooling are typically made from thick or cast ultra-thick aluminum slabs with a fine and uniform grain structure. Known for their excellent thickness tolerance and outstanding dimensional stability, these plates are ideal for precision machining applications. They offer excellent performance in welding, anodizing, and corrosion resistance, making them a preferred choice for mold bases, jigs, fixtures, and CNC platforms.Welcome contact

Specification and classification of Chalco aluminum tooling & jig products

In mold making and CNC machining, aluminum is favored for its excellent machinability, thermal stability, and lightweight strength. Depending on the processing depth and structural demands, engineers typically rely on two forms of aluminum materials: tooling plates for surface precision and flatness, and tooling blocks for thicker sections and deep cavity milling.

Chalco offers both product types with high dimensional stability and stress-relieved performance, ready to meet the needs of precision tools, fixtures, and industrial automation bases.
