The real development of investment casting in China is only a few decades. In the past few decades, China's development has been very rapid, and its proportion in the world is very high. For some workpieces with complex structures and not very high precision requirements, if it is difficult to process with CNC or the processing cost is high, such workpieces are especially suitable for investment casting. Even if some parts require precision assembly, we can meet the requirements through local precision CNC machining, thereby reducing costs. Especially for stainless steel castings, it is used in many places. Because of its strong corrosion resistance, high strength and toughness, stainless steel can be used in some harsh environments. For the processing of stainless steel parts, it is nothing more than precision CNC machining, forging processing, stamping processing, casting processing or powder metallurgy processing, etc., and investment casting is a relatively low-cost, high-precision processing method.
SCZY is a professional manufacturer of metal products. Many stainless steel castings we produce are used in marine projects, navigation, medical equipment and other industries. We not only provide metal investment casting processing, but also provide supporting follow-up secondary CNC machining and Surface treatment machining. We can ensure product accuracy requirements and appearance quality requirements.

(1) The normal use of the car, not over-speeding, overload, avoid rapid acceleration, driving as evenly as possible.
(2) Regular maintenance. As it turns out, car maintenance is very important for the quality of car emissions. Some cars are qualified when they leave the factory, but there will be problems like this in the process of use. They need maintenance to keep their cars in a good condition. Without timely maintenance, it will lead to more pollution due to high emissions. Such as: diligently check the car ignition system, timely detection of leakage, check the choke valve, check the air pipe, use a clean filter, avoid burning oil, avoid the use of low-grade lubricants.
OBD system repairs in time after failure. Once-a-year vehicle inspections have limited control over vehicle emissions. However, after the vehicle is installed with OBD, it is completely different. It can monitor the emission level of the car at any time. If the discharge fails, the OBD will issue a warning and promptly inform the driver to repair. The key to Euro III is the use of OBD.
(3) Use oil properly and use clean fuel.
(4) Abnormal emission due to indiscriminate change of vehicles.
(5) Select "green tires." The so-called "green tires" are also called green tires or low-polluting tires.
"Green" is mainly manifested in the fact that without losing its original good grip performance, tires maintain low resistance while rolling, thereby reducing fuel consumption and vehicle exhaust emissions, and effectively protecting the environment. As early as the 1990s, tire engineers discovered that if special silica is used instead of traditional carbon black as a reinforcing material for tread rubber, not only can the carbon black in the tire and carcinogens such as aromatic oil be contaminated by tire wear. Air, at the same time, the rolling resistance of the tires will also become smaller, the fuel consumption will be reduced, the exhaust emissions will be reduced, and a greater environmental protection effect will result.
(6) Vehicles must be scrapped and updated on time.
(7) Reduce the impact of car pollution. Do not arbitrarily decorate the interior of the vehicle; do not use inferior car perfume or air fresheners; if serious traffic jams are encountered, or if the vehicles that follow exhaust emissions may exceed the standards, the windows should be closed, and the air conditioners and heater switches should be adjusted to the vehicle's self-recirculation mode. Always check the hood and chassis for leaks. When you find a leak in the car, you should not turn on the air conditioner. Do not leave the air conditioner in the car to avoid danger. The air conditioner will inhale a lot of dust when it is used. Dirt, over time, moldy, and then distributed to the car through the air conditioning, in the car is easy to inhale the body, at intervals, the air conditioning to the maximum block, blowing for half an hour can effectively prevent dust accumulation; pay attention to The items near the air port were removed to ensure normal air circulation.
