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 .

How to distinguish whether there is a phenomenon of “burning oil” in your car

We all know that “burning engine oil” is very harmful to vehicles. It will not only damage the oxygen sensor of the vehicle too quickly, but also lead to increased carbon deposits in the combustion chamber, unstable idle speed, weak acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, insufficient lubrication of the engine may cause difficult-to-repair damage or even scrapping of the engine, resulting in a substantial increase in maintenance costs and even potential accidents. But for ordinary car owners, how to distinguish whether there is “burning oil” phenomenon in their car?
How to distinguish whether your car is “burning oil” can be distinguished from the following two phenomena: Phenomenon 1: The main manifestation of “burning oil” is that blue exhaust gas is discharged from the tail when driving, which means that too much oil has entered the combustion The chamber participates in combustion.
Phenomenon XNUMX: The oil dipstick detects excessive oil consumption.
Detection method: After the cold car starts in the early morning, check whether the exhaust pipe emits blue smoke; whether there is a lot of blue smoke from the exhaust pipe when the vehicle is driving or when the accelerator is stepped on the spot; in addition to the exhaust pipe, the oil port Blue smoke from time to time.
Expert analysis because the valve oil seals are aging and worn severely after long-term use, they can no longer achieve a good sealing effect. Therefore, some vehicles with a long service life or a large number of kilometers are more prone to “burning oil”. The reason for choosing to test in the early morning when the car is cold is that when the engine is not running for a long time, the oil will flow into the cylinder through the gap of the valve oil seal under the action of gravity. Once the engine is started, the oil in the cylinder will burn under the action of high temperature and high pressure, producing a lot of blue smoke. The detection method of slamming the accelerator is mainly to check whether there is a leaky seal between the piston ring and the cylinder wall of the engine. When the vehicle accelerates rapidly, the frequency of the up and down movement of the piston ring increases, and the lubricating oil remaining on the cylinder wall is easily carried into the combustion chamber by the piston ring, causing “oil burning”. If, under any circumstances, blue smoke comes out of the exhaust pipe, and blue smoke comes out of the oil port from time to time, it means that the engine has been worn out and the vehicle needs to be overhauled in time, otherwise it will cause serious accident hazards.
Maintenance tips Engine oil is very important to the protection of the engine. There are many reasons for the phenomenon of “burning oil”. Easily volatile oil, engine running-in, engine type, etc. may cause the engine to “burn oil”, but by strengthening the daily routine of the car Maintenance can reduce and avoid this risk. So, what maintenance tips should be paid attention to?
1. Develop good inspection habits. The oil should be checked regularly during routine and routine maintenance according to different usage conditions. If the oil level exceeds the lower limit, it should be added in time. For vehicles that have a long service life and mileage and are often used under severe conditions, the frequency of inspections should be increased accordingly. In this way, even if the vehicle is “burning oil”, it can achieve “early detection and early treatment” and reduce maintenance costs.
2. Choose better quality gasoline. After the additives in gasoline are oxidized, gelatinous substances are formed. After the fuel injectors enter the combustion chamber and burn, they will form carbon deposits on the intake valve, the top of the piston, the piston ring groove, the combustion chamber, the spark plug, etc., and aggravate these parts. The aging of the engine causes “burning oil”. Therefore, choosing better quality gasoline can reduce the phenomenon of “burning engine oil”.
3. Regularly maintain the vehicle. The maintenance period of the vehicle is formulated according to the normal driving conditions of the car. For vehicles with poor operating conditions, the maintenance period and the prescribed number of kilometers should be shortened according to the actual situation.
4. Choose better quality engine oil. The oil should choose well-known brands as much as possible. If conditions permit, the effect of using fully synthetic engine oil is better. High-quality engine oil not only has better cleaning performance, but also minimizes the wear of sludge and carbon-deposited parts, thereby reducing the occurrence of “oil burning”. At the same time, it also has better stability, making the oil in the engine Maintain proper viscosity level at high temperature and high speed to ensure effective sealing and reduce oil consumption.
