What é a Sandwich Panel?
A sandwich panel é a type de composite building material consisting de two layers de altostrength metal sheets (usually steel ou aluminum) bonded para an insulating core material in a middle. This “sandwich” structure combines lightweight design, excelente strength, thermal insulation, e durability.
É ofertas estrutural efficiency—tal como superior tensile e compressive strength from a dual metal layers, enquanto a lightweight core reduces global weight without sacrificing load-bearing capacity—fabrico ele suitable para wide-span roofs, wall cladding, e modular buildings.
Sandwich panels também provide outstanding thermal insulation (a core efetivamente blocks heat transfer, redutor energy consumption), enhanced fire resistance e safety (some core materials like rock wool são fire-resistant e improve a building’s fire rating), e ease de installation (modular desenho enables rápido e eficaz assembly).
O que é uma máquina para painéis sanduíche?
A máquina de painel sanduíche is a specialized mechanical system designed for the automated production of sandwich panels, which are composite building materials composed of two metal face sheets bonded to a core insulation layer. This machine integrates advanced manufacturing processes, including continuous roll-forming, laminating (compounding the core material with the metal sheets), and precision cutting, enabling high-efficiency, large-scale production. Among the various types, the PU Sandwich Panel Machine is a prominent example, focusing on the production of panels with a polyurethane (PU) foam core. This machine ensures consistent quality, rapid output, and adaptability to different panel specifications, meeting the demands of modern construction projects for lightweight, energy-efficient, and durable building materials.
