Difference between PA6 and PA66 in nylon family

Image
  Nylon, a revolutionary material, was born 80 years ago and was invented by Dr. Wallace Carothers of DuPont in 1935. It is the earliest synthetic fiber. Afterwards, DuPont led development of materials science and applied nylon as an engineering polymer, enabling it to achieve exponential development. Emergence of nylon has given a new look to textiles. Its synthesis is a major breakthrough in synthetic fiber industry and a very important milestone in polymer chemistry.  Main varieties and representative companies of nylon family are shown in following table: Nylon category Typical characteristics Representative enterprise PA6 PA6 is a translucent or opaque milky white particle. It has characteristics of thermoplasticity, light weight, good toughness, chemical resistance and good durability. It is generally used in auto parts, mechanical parts, electronic and electrical products, engineering accessories and other products. BASF PA66 PA66 is formed by polycondensation of adipic...

Design of Hot Runner Mould for Connecting Rod Parts

Image
【Abstract】In order to improve injection efficiency and material utilization of connecting rod components, hot runner technology is introduced. Design process includes plastic part analysis, mold design and assembly drawing design. It mainly introduces determination of design plan, selection of mold base and selection of hot runner system. Design process adopts UG full 3D design, which helps to make mold structure intuitive, to find problems and avoid unnecessary errors. 1 Introduction Hot runner injection molding is an important development direction of traditional injection molding. Its biggest feature is that plastic in runner system will not solidify during production process, nor will it be removed from mold with plastic part. Simply put, nozzle of injection molding machine is directly extended to plastic part for waste-free production, thereby greatly improving material utilization rate; at the same time, process is shortened and production efficiency is improved. In mold design p...

2019 automotive mould industry development status and market trend analysis

Image
Mold is an important basic process forming equipment in industrial production, often referred to as “mother of industry.” With rapid development of China’s automobile industry, automotive molding have become the most important component of China plastic injection molding industry and its’ scale continues to expand. Driven by national automobile lightweight policy, development of lightweight vehicles is an inevitable trend, which will effectively promote development of plastic injection molding. Demand for automotive molding is not decreasing, and scale of automotive mould industry is expanding steadily. According to statistics, more than 95% of parts on the car need to rely on mold for batch processing in the development of a new car, about 20,000 auto parts, including sheet metal parts, die-casting parts, stamping parts, plastic molded parts, electronic components and so on. In the development and manufacturing process of these parts, a large nu...
