What are the aspects of automotive materials that can be selected

The commonly used materials for automobiles are as follows: 1. Plastics: car interior body decoration, steering wheel, various handles, switches, wires, joints, headlight housings, bumpers, etc.

2. Glass: headlight bulb and window part. 3. Technical ceramics:

Engine spark plug insulation, high-temperature joints, ceramic valves and other parts. 4. Rubber: automobile tires, engine moving parts sealing rings, door and window waterproof sealing rings, engine pipes and other parts.

5. Leather: seat material.

When car owners buy car mats, they can judge the car mats by the following methods.

1. Look at the material of the car mat The material of the car mat can determine whether the cleaning is convenient, whether it is wear-resistant, whether it is environmentally friendly, etc., which is one of the important indicators to measure the quality of the mat.

2. See if the mat is non-slip Many traffic accidents occur because of the sliding of the car mat. The anti-cleats and anti-slip buckles on the surface of the mat are very important, and the design of the cleats is directly related to the fit and anti-slip effect of the car mat.

Method 2, look at the mat is the workmanship style The workmanship of the mat is very important, the high-quality mat can be used for 2-3 years, and the inferior mat is easy to break after half a year. At the same time, the good-looking style and excellent workmanship can reflect the noble temperament and taste of the owner!

Method 4, look at the sales volume and praise rate of online Tmall** several mat brands with the highest sales volume and the highest praise rate, such as Zhongxin, Jin Daofu, Wufu Taurus, etc.

Method 5, see if the mat has a peculiar smell To be honest, products like car mats will have a little taste, so after the owner buys the mat, it is best to put it in a ventilated place to dry for two or three hours.

The materials used to make automobiles are divided into metallic materials, non-metallic materials, and composite materials.

1. Metal materials: steel, aluminum, magnesium alloy, etc.

2. Non-metallic materials: ceramics, plastics, etc.

3. Composite materials: fiber reinforced ceramics, fiber reinforced metals, etc.

Introducing the production preparation of the car that has been tested and finalized, and the process, equipment and process equipment (tools, jigs, molds, gauges, etc.) need to be prepared before going into production.

Only some heavy-duty vehicles and special-purpose vehicles produced in small quantities do not require production preparation with a lot of work. In mass-produced automobiles, the process equipment coefficient (the average number of process equipment required for each part) is often 5 6, and the total manufacturing man-hours are in the millions.

In the major automobile-producing countries, the process equipment is manufactured by specialized factories, and the automobile factories only propose finalized product drawings and production programs. These specialized factories can be equipped with process equipment and special equipment in a very short time (about 1 year), so it is relatively easy for automobile manufacturers to change models.

Hello, there are many types of materials used in automobiles, such as cast iron; Alloy; Aluminum alloy; Steel; Copper; Plastics; Rubber; Cloth; Dermis; timber and so on.

Incoming materials I think you need a steel plate engine gearbox, then chassis as well as screws.

In a car, there are many parts with plastic, such as the center console, interior and exterior trim, engine peripherals, and so on. PP, ABS, PA, POM, etc. can be used. The plastics used in the periphery of automobile engines are mainly PA, such as PA6+MD20 for engine cover, PA+GF30 for intake manifold, weather-resistant hydrolysis PA66+GF30 for water chamber, PA6+MD20 for wheel cover, PA66+GF30 for fan blades, etc.

There are many materials used to make a car, the first of which is steel, oil, and precision instruments.

The materials used to make automobiles are divided into metallic materials, non-metallic materials, and composite materials.

1. Metal materials: steel, aluminum, magnesium alloy.

Wait. 2. Non-metallic materials: ceramics, plastics, etc.

3. Composite materials: fiber reinforced ceramics, fiber reinforced metals, etc.

Introduce. ProductionReadyTested and finalized automobiles require the preparation of processes, equipment and process equipment (tools, jigs, molds, gauges, etc.) before they are put into production.

Only some heavy-duty vehicles and special-purpose vehicles produced in small quantities do not need to be prepared for production with a lot of work in the first draft. Mass-produced automobiles tend to have a process equipment coefficient (the average number of process equipment required for each part in each base) of 5 6, and the total manufacturing man-hours are in the millions.

In the major automobile producing countries, the process equipment is manufactured by specialized factories, automobile factories.

Only finalized product drawings and production programs are proposed. These specialized factories can be equipped with process equipment and special equipment in a very short time (about 1 year), so it is relatively easy for automobile manufacturers to change models.

The selection of auto parts to consider the economy of materials is mainly from the perspective of the automobile factory, and ensuring the economy can ensure the profit margin of the automobile factory. Environmental considerations are the main consideration for user safety. For example, there are many automobile factories in Shanghai, which is because it is close to Baosteel, and the car object and skeleton are made of steel plates.

A car generally consists of four basic parts: engine, chassis, body, and electrical equipment.

1. Automobile engine: The engine is the power unit of the car. It is composed of the body, the crank connecting rod mechanism, the valve mechanism, the cooling system, the lubrication system, the fuel system and the ignition system.

2. Chassis: refers to the combination of four parts of the car consisting of the drive train, the driving system, the steering system and the brake system, which supports and installs the automobile engine and its various components and assemblies to form the overall shape of the car, bear the engine power and ensure normal driving.

3. Body: refers to the part of the vehicle used to carry people and goods, and also refers to the vehicle as a whole. The body of some vehicles is not only a driver's workplace, but also a place to accommodate passengers and goods. The body includes window closing, doors, and driving.

I will find out for you that the main properties of automotive materials are anti-collision; Because plastic has the advantages of light weight, beautiful appearance, high cost performance, easy processing and molding, it occupies an important proportion in auto parts, and now many parts and components such as bumpers, grilles, lights, dashboards, door panels, columns, seats, and front-end modules are judged to be made of plastic. Plastics are made of polymer resin, polypropylene, polyethylene, polystyrene, polyamide, etc. Mix talc, calcium carbonate, wollastonite, glass fiber and other reinforcing fillers; as well as polyolefin elastomers, butadiene elastomers, ethylene propylene rubber elastomers, etc. as toughening agents; In addition, various additives, such as antioxidants, weather resistants, heat resistant agents, antibacterial agents, etc. are blended and modified. In recent years, new energy vehicles have developed rapidly, making plastics more widely used in automobiles, and some developed countries regard the application of plastics in automobiles as an assessment of automobile manufacturing level and design standards.
