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 .

알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품 , 자동차 , 생활필수품 등 많은 산업과 분야에서 널리 사용되고 있습니다 . 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 몇 가지 결함 및 해결 방법은 다음과 같습니다 .   알루미늄 합금 다이캐스팅   1. 불순물   알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄 , 규소 및 다량의 철 , 망간 , 크롬 및 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다 .   해결책 : 알루미늄 잉곳의 조성을 엄격하게 제어하고 , 제련로의 난로를 정기적으로 청소하고 , 정기적으로 슬래그를 처리하면 문제를 해결할 수 있습니다 .   2. 구강 문제   다공성은 다이캐스팅 부품의 내부 또는 표면에 나타나는 다양한 크기의 구멍을 말하며 , 이는 다이캐스팅 부품의 경도 부족으로 이어져 표면의 외관에 영향을 줍니다 .   Solution: 적절한 정제제를 사용하여 모공을 처리하고 , 공정을 조정하고 , 저속을 적절하게 줄이고 , 이형제가 너무 많이 분사되어 모공 문제가 해결되지 않는지 확인하십시오 .   3. 균열 문제   균열은 알루미늄 합금 다이캐스팅의 매트릭스가 파괴되고 , 외력의 작용에 따라 확장되는 경향이 있는 선형 또는 기타 라인인 기다란 틈이 형성되는 것을 의미합니다 .   솔루션 : 합금 조성을 올바르게 제어하고 , 냉각수 회로를 늘리고 , 알루미늄 합금 다이캐스팅의 구조를 변경하고 , 사출 위치를 변경하거나 증가시키면 해결할 수 있습니다 . PINJIN 서비스에는 다음이 포함됩니다 . 알루미늄 다이캐스팅 , 아연 다이캐스팅 , 마그네슘 다이캐스팅 , 투자 주조 , 모

Establish a mathematical model of the automobile air-conditioning system

The heat exchanger model library uses this model library, and the user enters the parameters (including the use code of the heat exchanger, the type of the heat exchanger, the structural parameters of the heat exchanger, the material parameters, and the evaporator under the prompts of the software interface of the heat exchanger. After the inlet air volume or the front wind speed of the condenser, the dry and wet bulb temperature of the inlet air, the type of refrigerant, the flow rate of the refrigerant, and the temperature and pressure of the refrigerant at the inlet), calculate the heat exchanger in a given working condition Performance (including the heat transfer of the condenser, the cooling capacity of the evaporator, the pressure drop on the air side and the inside of the tube, and the temperature and pressure of the refrigerant at the outlet); the model library can also calculate the heat exchanger structure separately Changes in parameters, changes in the wind speed or volume of the air at the inlet of the heat exchanger, and changes in the performance of the heat exchanger when the temperature of the air at the inlet of the heat exchanger changes are reflected in the form of a curve. The model library can be used to calculate the relationship curve between the opening and flow of various types of H-type expansion valves and externally balanced expansion valves, providing a reference for users to select expansion valves reasonably.

Liquid storage tank model library Calling this model library can calculate the volume and flow resistance of various types of liquid storage tanks. Provide a reference basis for users to reasonably select liquid storage tanks. The air conditioning system model library reasonably selects the automobile air conditioning refrigeration system based on the heat load value calculated by the heat load model library, the allowable installation space location of the car, and the existing component products, and then establishes the mathematical model of the automobile air conditioning system. The following functions can be realized by using this model library: simulation simulation calculation of simulation bench test; calculation of multiple operation modes can be carried out. It can calculate the known refrigerant charge or the required refrigeration capacity; calculation of multiple connection methods; for a given automobile air-conditioning refrigeration system, the compressor speed, the condenser inlet air temperature or the oncoming Under the conditions of wind speed, variable evaporator inlet air temperature or air volume, the performance of the automobile air-conditioning refrigeration system (such as cooling capacity, power consumption, coefficient of performance, evaporator outlet air temperature, compression ratio, compressor suction temperature and The influence law of pressure, exhaust temperature and pressure) is expressed in the form of curves, so as to provide a reference basis for predicting the matching rationality and working conditions of the automobile air conditioning system.
