Cube Maker System utilizes disposable polypropylene mold liners that fit into a permanent three-gang stainless steel frame. Cured cubes are lifted out of the frame and the liners are stripped away. The reusable frame never needs cleanup. The system includes an unbonded capping set of four polyurethane pads with two stainless steel retainers, reusable for up to 300 compression tests, and 27 Poly-liners. This inexpensive, timesaving system is reliable for in-house quality control and other non-specification applications. Liners, pads, and extra mold frames are available separately.
