Car nylon application inventory! This is the flare of the plastic revolution!
2023-11-20
Parts in automobiles are an important and rapidly developing field of nylon product application. Nylon has very good comprehensive performance, easy molding and low density, so it has been well applied in mold development and assembly; in addition, its thermal insulation and Good insulation performance makes the design range of nylon wide.
Nylon parts in engine area
The internal parts of the automobile engine area need to withstand the influence of long-term hot and cold environment. The usual standard is that the parts need to withstand a temperature of -40~150 ℃, which can meet the use environment of alternating hot and cold throughout the year. In addition, the parts in the engine area also need to be able to withstand the impact of deicing agent calcium chloride, long-term antifreeze, various oils and flying sand.
Oil filter
The oil filter is a component that filters out oil residue and foreign matter when the oil sucked out in the oil pan is distributed to various components in the engine through a filter screen installed on the oil pipe. Before nylon is used to replace metal, The oil filtering function is realized by a filter screen installed between the steel pipe and the flange; after glass fiber reinforced nylon material is used instead of metal, in the design, the upper part and the middle part of the steel pipe in the original scheme are respectively injection molded with nylon 6+10% glass fiber modified plastic, and the metal filter screen and the middle part are welded together. The oil filter uses nylon 6+10% glass fiber modified material to reduce the air mixing rate by 10 to 30 percentage points, the overall cost can be reduced by 50%, and the total weight of the parts can be reduced by 70%.
Engine cover
In order to achieve the purpose of reducing noise and improving ride comfort during vehicle use, the engine adopts a cover made of glass fiber reinforced nylon material with noise shielding function. The overall component is made of glass fiber reinforced nylon material, and the inner surface is compounded There are sound insulation materials. With the increasingly fierce competition in the automobile market, people continue to expand the range of vehicle models, and the requirements for vehicle comfort continue to increase, more and more manufacturers are assembling this part in more and more models. It can greatly shield the sound of the engine, especially the direct fuel injection engine, and also improve the appearance of the cabin, making the cabin look cleaner.
The engine cover requires materials with: high strength and toughness, low warpage, high apparent quality, high fluidity, easy to process quickly.
