What kind of equipment are polyurethane equipment divided into? Equipment polyurethane spraying machine polyurethane spraying equipment, polyurethane high-pressure spraying machine, foaming machine, polyurethane foaming machine, polyurethane high-pressure foaming machine.
Sprayer, spray technology uses a special coating equipment, its principle is to promote the reverse rotation of the air flow control valve reversing device, and the piston air motor is now a stable continuous reciprocating motion. Pressurized spray through a high-pressure hose, conveyed through the spray gun to the machine gun, the paint is sucked into the painted surface at the moment the paint is released. The sprayer is mainly composed of a feed device, a spray gun, and the composition of the spraying source. Suitable for leather handbags, gift packaging, furniture, footwear, automobile manufacturing and other industries.
Spray polyurethane foam, and include direct spraying of polyurethane primer and synthetic resin, such as spraying in two parts. Primers and a synthetic resin are mainly used for direct spraying for corrosion resistance, sealing, insulation, etc. It is characterized by good wear resistance and excellent erosion. The spray can be formed without spray suspension flow phenomenon from 25u coating to a few millimeters.
Spray polyurethane, polyurethane high-pressure spray equipment. Because of the high-speed impact of the material high-pressure spraying equipment in the violent mixing chamber and the small rotating space, the mixing is very good. The material in the muzzle forms a fine mist of droplets that moves at high speed and is evenly sprayed on the surface of the object.
Polyurethane spray foam is mainly used for insulation, insulation and sealing in refrigeration, molds that are not easy to use, such as coated large spherical storage tanks, large diameter pipes, cold storage walls and other thermal insulation materials can achieve foaming.
High-pressure foaming machines are widely used, mainly for sponges, soft foams, refrigerators, freezers, freezers, water heaters, disinfection cabinets, solid wood furniture, pipe insulation, automotive interior parts, warehouse boards, mobile cabins, seats, sponges, toys And other products fill the production of insulation materials.
The foaming agent is a certain concentration of the aqueous solution that the foaming machine reaches to the finished foaming device. The foaming agent itself cannot automatically become a foam, and a mechanical action must pass to become a foaming machine foam.
Polyurethane foam is a machine pouring and foaming equipment for polyurethane foam. Only the component polyurethane raw material (the part of the isocyanate group with the polyether polyol component) is in accordance with the required performance indicators of the formulation. Through this equipment, uniform and qualified foam products can be produced. It is based on polyether polyol, and in the presence of foaming agent, catalyst, emulsifier and other chemical additives polyisocyanate, foam prepared by chemical reaction foaming. Polyurethane foaming machine can be used in automotive interior parts, exterior wall insulation coatings, insulation pipe manufacturing, bicycle and motorcycle seat cushion sponge processing.
High pressure polyurethane foam injection machines are essential equipment for modern PU foam production. This article explains the working principle, key components, high-pressure mixing technology, advantages, and industrial applications of polyurethane injection machines, helping manufacturers understand how to choose the right PU foaming equipment for automotive, furniture, insulation, and other industries.
From August 25 to 27, 2026, EV TREND KOREA 2026 — the three-day Seoul exhibition dedicated to new energy vehicles and charging infrastructure — successfully concluded. As one of the most influential new energy industry events in Korea, the show brought together global manufacturers of electric vehic
Choosing between a high-pressure and low-pressure polyurethane foam injection machine depends on production volume, foam quality requirements, mixing technology, operating costs, and application. This guide compares both systems in detail to help PU manufacturers select the right equipment for automotive parts, furniture, mattresses, insulation materials, and other foam products.
On August 13, 2026, Shandong Hightop Group officially opened its 2026 Mid-Year Sprint Awards & Summary Conference under the theme "Reviewing to Break Through, Tempering Excellence; United in Purpose to Create New Glory." With half of 2026 already behind the team, department heads and all business st
From August 25 to August 27, 2026, Hightop Group will participate in EV TREND KOREA 2026, one of Korea’s leading new energy vehicle and charging technology exhibitions, held at COEX Convention & Exhibition Center in Seoul.
Polyurethane (PU) foam has become an essential material in modern manufacturing due to its excellent thermal insulation performance, lightweight structure, flexibility, and long service life. Compared with traditional foam materials, polyurethane foam provides manufacturers with greater possibilitie
