First, material preparation
Marine air bags mainly use high strength synthetic fiber materials, such as polyester, nylon and so on. First of all, the fiber material needs to be cut, separated, short-fiber and carding processes, so that it is evenly distributed throughout the air bag to improve strength and toughness.
Second, mold manufacturing
Making mold is the key link of Marine airbag production. The accuracy of the mold determines the quality and production efficiency of the finished product. Generally made of glass steel or aluminum alloy mold, with light weight, corrosion resistance and other advantages. When making the mold, it is necessary to pay attention to the flatness and streamlined design of the mold surface to ensure the beautiful appearance, airtight performance and service life of the finished product.
Third, molding process
Molding process is the core of Marine air bag production. The molding process is mainly divided into blow molding, pressure molding and extrusion and other ways, of which blow molding is the most widely used method. In the blow molding process, the processed material is first stuffed into the mold, and then air is injected into the mold to expand the air bag. After high temperature and high pressure treatment, the surface of the air bag will form a flat and smooth appearance.
Fourth, post-treatment process
After forming, it is also necessary to carry out post-processing process, mainly including cutting, bonding and sealing. The surface of the airbag is coated with a polyurethane or acrylic composite material to improve its wear and corrosion resistance. At the same time, in the various connecting parts of the air bag, it is also necessary to use high-strength rubber belts or metal fixtures to tighten to ensure the safety and reliability of the air bag.
The above is the production process of Marine air bags, each step is very critical and indispensable. Through fine production and comprehensive quality control, we can manufacture high-quality Marine air bags to meet customer needs and requirements.
