Introduction: Speed Matters in Insulation Material Production With rising demand for PU insulation bricks in green buildings and prefabricated construction, manufacturers are under pressure to deliver large volumes with consistent quality. The market require good PU brick cutting machine urgently, However, cutting polyurethane foam blocks—especially thick, rigid ones—poses unique challenges. Traditional methods often struggle to keep up with production speed without compromising surface finish or dimensional accuracy. This is where the Endless Diamond Wire Saw (EDWS) becomes a game-changer. Originally developed for cutting hard and brittle materials like ceramics and sapphire, EDWS has proven to be a highly efficient and reliable solution for cutting soft but structurally sensitive materials like PU thermal bricks. Section 1: What Is an Endless Diamond Wire Saw? An endless diamond wire saw uses a closed-loop diamond abrasive wire that moves continuously around a set of pulleys. Unlike reciprocating saws or spooled wire systems, the loop
