Application field

In the field of aerospace, vacuum auxiliary materials play an irreplaceable role. Composite material forming is the core technology of aerospace parts manufacturing. Vacuum bag film, breathable felt and other auxiliary materials are the key to vacuum autoclave forming and vacuum filling processes. Vacuum bag film needs to have high sealing and high and low temperature resistance to ensure stable pressure during the molding process; breathable felt can effectively discharge air and excess resin, improve the compactness of composite materials; demoulding cloth ensures that the molded parts are completely out of the mold and avoid surface damage. The precise application of these vacuum auxiliary materials has greatly improved the strength, lightweight level and reliability of aerospace parts, helped to optimize the performance of aircraft, and laid a solid technical foundation for the development of aerospace industry.

In the field of yacht manufacturing, vacuum auxiliary materials are the core elements to improve product quality and performance. Vacuum filling process is often used for yacht hulls and key components, and auxiliary materials such as vacuum bag film, diversion net, and demoulding cloth are indispensable. Vacuum bag film has excellent sealing performance and flexibility, and can closely fit complex mold contours to form a closed vacuum environment. The diversion net guides the resin to penetrate evenly and quickly, shortening the curing time. Demoulding cloth prevents resin adhesion and ensures that the surface of parts is smooth and smooth. Through the synergistic use of vacuum auxiliary materials, not only the efficiency of yacht manufacturing is improved, but also the strength and corrosion resistance of the hull are enhanced, and the lightweight design is realized, so that the yacht has both safety and navigation performance.

In the manufacturing of high-speed rail, vacuum auxiliary materials play a key role in effectively ensuring the performance and safety of high-speed rail. Taking the vacuum bag film as an example, it is mainly made of nylon and polyethylene multi-layer co-extrusion, which has good sealing and flexibility. In the composite molding process of high-speed rail parts, it can closely fit complex molds to create a stable vacuum environment, allowing the resin to evenly infiltrate the fiber material and improve the strength and stability of the parts.

The breathable felt and the guide net are also indispensable. The breathable felt can effectively expel air and excess resin, and improve the compactness of the composite material; the guide net can guide the rapid flow of resin, shorten the curing time and improve the production efficiency. Like the pantograph and bogie of high-speed rail, these vacuum auxiliary materials are used in the manufacture to ensure that the parts meet the strict requirements of high-speed rail operation. 

In the wind power industry, vacuum auxiliary materials are the key elements to ensure the efficient production and stable performance of blades. In the vacuum infusion molding process, vacuum bag film, mold release cloth, diversion net and other auxiliary materials are indispensable. The vacuum bag film has good air tightness, high temperature resistance and mechanical strength, which can effectively build a vacuum environment and ensure that the resin is evenly infiltrated into the fiber material; the release cloth can enhance the interlayer bonding and improve the structural strength of the blade; the diversion net optimizes the resin flow path and accelerates the infusion speed. Through the synergistic effect of vacuum auxiliary materials, not only the production efficiency of wind power blades is improved, but also the dimensional accuracy and quality stability of the blades are guaranteed, providing strong support for the reliable operation of wind power equipment.
