Changes in the mode of travel have made automobiles the most important mode of transportation in modern times. The increase in demand for automobiles has directly led to the development of the automobile manufacturing industry.
Automobile manufacturing involves stamping, welding, grinding, painting, machining and other processes. And there are four main manufacturing processes: stamping, welding, painting and assembly, which are also the four major processes of automobile often mentioned by everyone.
With the development of science and technology, the current automobile manufacturing has achieved a wide range of mechanization and automation. However, in the process of automobile manufacturing, noise, welding fumes, chemicals (benzene compounds, manganese compounds, acetone, butanone, carbon monoxide, nitrogen dioxide, etc.), ultraviolet and other hazardous factors still exist. The health of the relevant practitioners may be jeopardized when they come into contact with materials such as topcoats and thinners, and when they carry out operations such as material handling, workpiece grinding, welding, and rework.
Stamping Workshop - Noise
Stamping is a molding process that relies on presses and dies to apply external forces to plates, strips, tubes, profiles, etc.，makes it produce plastic deformation or separation, so as to obtain stamped parts that match the design. The four doors, roof, trunk plate, floor and other parts of the car are stamped.
In the uncoiling, drop material, stamping and picking up materials and other processes of stamping workshop will produce a lot of noise. And the sound level is high, which can exceed the human body to withstand. Practitioners working in persistent noise environments for long periods of time develop hearing loss and even occupational noise deafness.
Recommended equipment: anti-noise earplugs, helmets, gloves, safety shoes, etc.
Welding workshop - welding fume, manganese compounds, etc.
Welding is a process of joining metals or other thermoplastic materials by means of heat, high temperature or high pressure. Vehicle bodies are welded from stamped parts, initially forming a complete vehicle, and a vehicle has over a thousand welded joints.
Traditional welding shop work is more dangerous. The welding current can reach thousands of amperes, which produces a lot of fumes. It’s by-products also have a greater harm, such as manganese and its compounds, if not properly protected, inhalation can lead to dizziness and nausea or even poisoning.
Recommended equipment: mask/half mask, goggles, gloves, earplugs, safety shoes, etc.
Paint shop - benzene compounds, etc.
Automobiles are usually painted by spraying to form a coating on the white body, which can enhance the service life and aesthetics of the automobile.
Occupational hazards in the paint shop mainly come from benzene compounds. The materials involved in automobile spraying include top coat, thinner, glue and other additives, which produce a lot of exhaust gas in the spraying process. The exhaust gas not only contains benzene compounds, but also esters, ethers, ketones and other components, which can bring greater harm to the health of the practitioners. If the protection is not appropriate, it can lead to poisoning, and even lead to blood system disorders, inducing leukemia.
Recommended equipment: goggles, masks/half masks, protective clothing, gloves, earplugs, safety shoes, etc.
Final assembly shop - noise, toxic and hazardous gases, etc.
Final assembly workshop is responsible for assembling. On the basis of the painted car, the remaining automobile parts and components are assembled together. After quality testing (test drive), the final finished vehicle is obtained.
The final assembly workshop includes assembly (interior, chassis, exterior, etc.), vehicle testing and other procedures, and the main occupational hazards are noise and toxic and hazardous gases. For example: traditional fuel vehicles rely on the engine to provide power. In the workshop testing process, the engine can produce a lot of noise, as well as carbon monoxide, nitrogen dioxide and other gases, posing a threat to health.
Recommended equipment: helmet, earplugs, mask, gloves, safety shoes, etc.
In addition, traditional fuel car power provided by the engine, engine casting produces a large amount of silica dust, inhalation of the respiratory system there is a risk of silicosis.
New energy vehicles, such as pure tram power, generally supplied by the battery. The battery manufacturing also exists in a large number of occupational hazards, prone to heavy metal poisoning, pneumoconiosis and so on. For example, the production of lithium batteries, in the dosing, coating and other processes will come into contact with graphite dust, liquid injection process will come into contact with hydrogen fluoride, rolling mold, scrubbing will come into contact with ketones. In addition to high temperatures, noise is also a lithium battery manufacturing occupational disease risk factors.
One of the core components of new energy vehicles - circuit boards, in the manufacturing process, involving open material, green oil solder resist, etching, copper plating and other processes. The operation of the process of dust, noise, acid and alkali, other types of chemical toxins factors. On the whole, the main hazards to human beings for cyanide, formaldehyde, ammonia and trichloroethylene, which can cause irreversible damage to the practitioner's body. Practitioners can cause irreversible damage to the body, they should be equipped with protective clothing, gloves and gas masks.
As production advances with the times and technology improves, the impact of various hazards on workers is also better controlled. Beyond technological improvements, providing protection is still a necessary way for companies to protect their employees. When the employees are healthy, the production of the enterprise will be safe and stable, and generate sustainable benefits. KINGFA industrial protection series has covered gloves, protective clothing, dust masks and other products, escorting the automotive manufacturing industry practitioners, providing professional and complete customized solutions for your business and employees.
