What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃.   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

High-quality lubricants are indispensable for engine maintenance

How to protect the car engine, how to maintain the excellent performance of the engine, and reduce the maintenance cost caused by the engine failure repair? For car owners, this is the focus of attention.

The heart of the automobile engine makes the oil depend on the fast movement of this part and the poor environment. The working temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the engine parts Wear and prolong service life.

Engine as a kind of machinery, the requirements for lubricating oil have in common with general machinery, such as proper viscosity, certain anti-oxidation, anti-wear, anti-corrosion and viscosity-temperature performance requirements. But the engine is a special kind of machinery, and its requirements for lubricating oil have its special side, and its particularity mainly includes:

1) The general requirements for the engine are small size, light weight, compact structure, and large output power, so its unit friction surface bears a large load.

2) In addition to frictional heat, it is also affected by combustion heat. Therefore, the temperature of the friction surface is very high, which reduces the viscosity of the lubricating oil and makes it difficult to form an oil film.

3) The high-temperature and high-pressure combustion gas in the combustion chamber will leak to the crankcase through the gap between the piston, piston ring and cylinder liner. These combustion gases are the gas produced by the complete combustion and incomplete combustion of fuel and a small amount of lubricating oil. Some particulate matter (soot) usually becomes the main component of crankcase blow-by, which will pollute the lubricating oil and promote its oxidation under certain conditions.

4) The lubricating oil needed around the combustion chamber enters through the gap between the piston and the cylinder liner, and the gap between the valve stem and the valve guide, so it is difficult to supply oil.

5) Pistons, valves and other parts reciprocate during work, so the relative speed at the top and bottom dead centers is zero, making it difficult to form an oil film. The piston pin and the bushing are in oscillating motion, and the oil film is difficult to form.

6) When the engine is stopped and running for a long time, the temperature is very different, and due to the thermal expansion and thermal deformation of the parts, it is difficult to control the constant gap of some friction pairs. The gap may be too small to cause adhesion and sintering, or it may be caused by The gap is too large to cause shock and vibration to cause damage. In these cases, the oil film is difficult to adhere.

7) There are a variety of friction pairs in the engine, such as pistons and cylinder liners, crankshaft journals and bearings, cams and followers, gears, etc., although they have different requirements for lubricating oil lubrication performance, but in an engine Only one type of lubricating oil can be used (except for large marine diesel engines), so a variety of lubrication conditions should be taken into consideration when choosing lubricating oil.

8) The use environment of vehicle engines is complex, such as temperature, humidity, atmospheric pressure, dust, etc. change greatly. At the same time, because the engine oil often contains elements such as sulfur and lead, it will promote the corrosion and wear of certain parts.
