Why PU Insulation Blocks Require Precision Cutting
In this article, we explore why PU insulation block cutting demands accuracy and care, the problems with conventional cutting methods, and how diamond wire cutting technology offers a cleaner, more efficient solution for processing polyurethane insulation blocks. Polyurethane (PU) insulation blocks are a cornerstone of modern energy-efficient construction. With excellent thermal resistance, low water absorption, and structural stability, PU materials are widely used in prefabricated wall panels, cold storage, and building facades. However, their unique material properties make cutting them a technical challenge—especially when precision, cleanliness, and repeatability are required. Section 1: Why PU Insulation Blocks Are Difficult to Cut PU blocks—whether rigid or semi-rigid—combine a lightweight foam core with a fragile surface structure. While the material is not as hard as ceramics or metals, its low density and elastic deformation introduce specific challenges: Section 2: The Limits of Traditional Cutting Technologies Many manufacturers rely on band saws, reciprocating blades,
