Оборудование для формовки сэндвич-панелей

Sandwich panel roll forming machines are used to produce sandwich panels, which are structural panels made by sandwiching a core of insulation material between two skins of metal. Sandwich panels are widely used in industrial, commercial and residential building construction for walls, roofs and cold storage applications due to their high strength-to-weight ratio and excellent thermal insulation properties.

This comprehensive guide provides detailed information on various aspects of sandwich panel roll forming machines to help manufacturers, buyers and engineers understand their working, selection criteria, applications and more.

Overview of Sandwich Panel Roll Forming Machines

Sandwich panel roll forming is a continuous production process for manufacturing sandwich panels. In this process, the sheet metal coils for the panel skins are fed into the roll forming machine along with the core insulation material. As the materials pass through the different roller stations in the machine, they are gradually bent into the desired panel profile. The top and bottom skins get attached to the insulation core to produce a continuous length of the sandwich panel which is cut into required lengths by end cutters.

Оборудование для формовки сэндвич-панелей allow quick and efficient production of sandwich panels in a wide range of specifications. Key features of these machines include:

  • High production speeds up to 25 m/min
  • Capability to make panels up to 1250 mm width
  • Flexibility to produce different panel thicknesses and profiles
  • Integrated skin embossing and punching options
  • Automatic core feeding and gluing system
  • User-friendly controls and recipe management software

These machines require less manpower compared to traditional sandwich panel production methods. The finished panels from the roll former have a uniform profile with good dimensional accuracy. advanced roll forming machines also enable inline printing and protective film lamination.

Main Components of Sandwich Panel Roll Forming Lines:

  • Uncoiler and guiding system for feeding sheet metal coils
