When we consider fasteners, bolts, nuts and washers, we assume steel or alloy products; The fastener market for plastics, nylon and polypropylene is important. Fasteners made of nylon have unique properties that make them ideal for a variety of functions. When nylon was first developed by DuPont's Wallace Carothers in 1935, it was originally intended to be a cheap and mass-produced alternative to silk, including nylon stockings for women, one of their first products. Before long, nylon was molded into many other products and extended to bolts, nuts, screws, washers and many other industrial fasteners. Nylon fasteners are non-conductive, non-corrosive, non-magnetic, durable, impact resistant, light weight. These properties are critical for applications involving electrical or chemical environments.
Plastic fasteners development Plastic fasteners are a key development in the fastener market, and the sales growth of plastic fasteners, especially nylon fasteners, is very significant. Through the research and development of composite materials to achieve technological breakthroughs. Different from metal fasteners that have been heat treated and cold worked or hot worked; Plastic fasteners are produced by injection molding. Technological developments have given plastics the same performance characteristics as metals, such as material toughness, corrosion resistance and heat resistance. The different types of plastic fasteners that are increasingly popular in automotive applications include nylon, acetyl, polyvinyl chloride, polyvinylidene fluoride or PVDF and phenolic fasteners. With the development of polymer composite plastic fasteners and shape memory polymers, the number of plastic fasteners used in automobiles is steadily increasing, which helps to expand the use of plastic fasteners in automotive engineering. Stringent fuel efficiency mandated by government legislation around the world and the subsequent focus on lightweight vehicle design has driven the use of plastic fasteners.
Benefit from the growing preference for advanced lightweight bolts, screws, washers and nuts; Traditional fastener manufacturers have begun to expand their product portfolios to include plastic fasteners, especially nylon fasteners, which are becoming increasingly popular. Technological breakthroughs made in the research and development of composite materials, glass and metal fillers are often used in combination with plastics to improve strength and performance. Unlike metal fasteners, which are heat treated and cold worked, plastic fasteners are produced through a process called injection molding. Technological developments have given plastics the same performance characteristics as metals, such as material toughness, corrosion resistance and heat resistance. Corrosion resistance even when exposed to moisture is considered a significant advantage of plastic fasteners over stainless steel fasteners. Also driving the use of plastic fasteners are stringent fuel efficiency regulations legislated by governments around the world. The automotive manufacturing industry is currently evolving in line with the growing concept of vehicle lightening to reduce emissions and improve fuel efficiency.
