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℃. invest-casting.com   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 .

Analysis of Misunderstandings in Automobile Maintenance

Caring for a car must pay attention to science. However, some problems often arise in car maintenance. Some people thought they were caring for the car, but in fact they accidentally damaged the car.

Maintenance experts remind you that the following wrong maintenance method is equivalent to destroying the car.

1. Waxing in a circle

The effect is poor. Many people habitually wax the car in a circle. This is an incorrect method. The correct way of waxing is in a straight line, alternating horizontal and vertical lines, and then in the direction of rainwater flow. In this way, the effect of reducing the concentric circular halo on the paint surface can be achieved.

2. Too much oil

Failure When the oil in the engine oil pan is insufficient, the friction between the bearing and the journal will be due to the small amount of oil, poor lubrication, aggravating the degree of wear, and even causing a bush-burning shaft accident. However, if there is too much oil, the crankshaft handle and the big end of the connecting rod will be violently agitated when the engine is working, which not only increases the internal power loss of the engine, but also increases the oil splashing on the cylinder wall and causes the oil burning failure. . Therefore, the oil in the engine oil pan should be controlled between the upper and lower engraved lines on the oil dipstick.

Three, the bolt is too tight

There are many fasteners connected with bolts and nuts on permanent deformation cars. It should be ensured that they have sufficient pre-tightening force, but they should not be over-tightened. On the one hand, the connecting parts will be permanently deformed under the action of external force; on the other hand, On the one hand, it will cause the bolt to produce tensile permanent deformation, and the pre-tightening force will decrease, and even cause the phenomenon of sliding buckle or breaking.

Fourth, the fan belt is too tight

The bearing load is heavy and the temperature is too high in summer. Some drivers think that increasing the tightness of the fan belt will cause the fan belt to be too tight, but they do not know that this is wrong. The fan belt should be properly tight, because too tight will cause excessive bearing load, aggravate wear, and increase power consumption. At the same time, it will also cause the water pump shaft to bend, elongate the belt and shorten its life.

5. The new battery does not charge

The first charge of a battery with a shortened life is called the first charge, and the first charge has a great influence on the service life of the battery. If it is not charged, that is, if it is used directly with “water”, the capacity of the battery is not high and its life will be shortened; if it is directly charged, it will also shorten its life. Generally, the initial charging of the battery is after filling the electrolyte, and then it can be installed and used after charging with a small current for about 1 hour.

VI. Add equipment in the car at will

A personal car that affects driving safety is a mobile home for car owners. There is nothing wrong with pursuing passenger comfort and luxury. However, some car owners install various equipment in the car by themselves. This modification, if not handled properly, will affect the performance and operation of the car. Reliability often brings adverse effects, and it is easy to leave sequelae or affect driving safety.

Seven, the cooling water temperature is too low

Wear and tear of the engine In the hot summer weather, some drivers blindly require the cooling water temperature to be as low as possible in order to prevent the engine temperature from being too high; some drivers simply remove the thermostat to achieve the purpose of cooling down. These practices are wrong.

Automobile engines are both afraid of heat and cold. If the cooling water temperature is too low, it will worsen fuel combustion, increase fuel consumption, aggravate wear, increase oil viscosity, and reduce engine power. Tests have shown that when the cooling water temperature of the car is 40-50 degrees Celsius, engine wear will increase by 60%-80%, power will be reduced by 25%, and fuel consumption will increase by 8%-10%. Therefore, the temperature of engine cooling water is not as low as possible. , Generally should be controlled between 80~90 degrees Celsius.
