Jul 11, 2025

PU Sandwich Panel Manufacturing Machinery is a key equipment for producing polyurethane sandwich panels. When selecting and using, comprehensive consideration should be given to production needs, equipment performance, and quality to ensure the production of high-quality polyurethane sandwich panels.

PU Sandwich Panel Manufacturing Machinery

The PU Sandwich Panel Manufacturing Machinery mainly includes foaming machines, molding equipment, cutting equipment, etc.

  • Foaming machine: The foaming machine is the core equipment of the polyurethane sandwich panel production line, used to mix and foam polyurethane raw materials. There are various types of foaming machines, such as high-pressure foaming machines, low-pressure foaming machines, continuous foaming machines, etc., and suitable types can be selected according to production needs. High pressure foaming machine is suitable for producing sandwich panels with high density and strength; Low pressure foaming machines are suitable for producing sandwich panels with lower density and better insulation performance.

  • Forming equipment: The forming equipment is used to composite foamed polyurethane with surface materials (such as color steel plates) to form sandwich panels. Common molding equipment includes press injection molding equipment, continuous composite molding equipment, etc. These devices inject and solidify polyurethane raw materials through molds, and then composite them with surface materials to obtain the desired sandwich panel size and shape.

  • Cutting equipment: The cutting equipment is used to cut the produced polyurethane sandwich panels into the required size. Cutting equipment usually has high precision and automation characteristics, which can ensure accurate size and smooth edges of the cut sandwich panels.

The production process of polyurethane sandwich panels is roughly as follows:

  • Preparation materials: including color steel plates, polyurethane raw materials, etc.

  • Cutting color steel plate: According to the required size of the sandwich panel, use cutting equipment to cut the color steel plate into the appropriate size.

  • Gluing and compounding: apply a layer of glue on the surface of the color steel plate to bond the polyurethane foam and the color steel plate together. Then inject the polyurethane raw material into the mold and composite it with the color steel plate.

  • Foaming and curing: After injecting polyurethane raw materials into the mold, foaming treatment is carried out. After foaming, wait for polyurethane foam to solidify.

  • Cutting and trimming: Use cutting equipment to cut the cured polyurethane sandwich panel into the required size and trim it to make its surface flat.

  • Quality inspection and packaging: Conduct quality inspection on the produced polyurethane sandwich panels to ensure they meet relevant standards and requirements. Then package it for storage and transportation.

At present, the PU Sandwich Panel Manufacturing Machinery market presents diversified and automated characteristics. With the continuous advancement of technology and the expansion of the market, the performance and quality of PU Sandwich Panel Manufacturing Machinery are also constantly improving. In the future, PU Sandwich Panel Manufacturing Machinery will pay more attention to the development of energy conservation, environmental protection, and intelligence to meet the market's demand for high-quality sandwich panels.
