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

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

Analysis of technical hot spots and obstacles in the process of automobile lightweight

Continuous fiber-reinforced thermoplastic resin instead of traditional metal-based materials can be said to be the hottest technology that the current automotive lightweight field pays attention to. Judging from the K2013 exhibition, no less than 10 companies exhibited solutions for this technology. The seat shell made of TEPEXdynalite102-RG600(2)/47%-1.0mm from Bond-Laminates Co., Ltd., a subsidiary of LANXESS, is made of thermoplastic composite material reinforced with continuous-length glass fibers. This kind of seat shell has extremely high rigidity and strength, and can absorb a large amount of energy in the event of a collision, thus greatly improving safety.

Dr. Christian Obermann, General Manager of Bond-Laminates, said: “The weight of the new product is about 800g lighter than the previous product, and its performance can easily outperform products of the same structure made of steel plate and long glass fiber reinforced plastic.” Automotive lightweighting process The technology hotspots and hindrances in LANXESS expects that the demand for TEPEX-based composite products will increase. Obermann said: “We have found that there is also huge application potential in other automotive structural components that require excellent load capacity, such as brake pedals, airbag housings, front and rear seat structures, front-end carriers, and underbody protection components. . So we are now expanding the TEPEX industrial production capacity of our Brilon production plant.”

Owens Corning, the world's largest manufacturer of glass-reinforced fiber and composite engineering materials, took the opportunity of the 2014 Chinaplas to launch its upcoming PerforMax designed for long-fiber-reinforced thermoplastic polypropylene (LFTPP) to be introduced to the Chinese market. Series SE4849Type30 direct yarn, suitable for polypropylene resin long glass fiber granulation, continuous fiber melt impregnation, in-line long glass fiber reinforced thermoplastic and continuous fiber reinforced thermoplastic sheet. SE4849 realizes faster composite production line speed, improves efficiency and increases glass fiber load. Continuous fiber reinforcement has not only attracted much attention in raw material companies, but also equipment manufacturers have also paid close attention to this technology. **Injection technology providers Arburg, Engel, KraussMaffei, extrusion technology manufacturers BREYER, Milacron extrusion, Reifenh? user, pressure forming technology provider Diffenbacher, and inspection technology provider IsraVision all exhibited solutions for this technology at K2013. Undoubtedly, continuous fiber reinforcement technology, including other long fiber reinforcement technologies, has become an important direction for high performance and lightweight. But at the same time, the high price of high-quality materials has undoubtedly increased the cost of lightweighting. The shortcomings of local independent brands in sales and R&D funds have made modified plastics used in automotive applications to be loved by car companies. Hate it again.

Faced with increasingly stringent automobile fuel consumption regulations, major car companies are looking for a variety of ways to reduce fuel consumption, including reducing body weight. Through the increase in the amount of modified plastics used in automobiles, the weight of the car body can be reduced, and the purpose of reducing fuel consumption can be achieved. In Europe, the amount of modified plastics used in automobiles has become an important indicator to measure the level of automobile design and manufacturing. According to statistics, 1kg of modified plastics can replace 2-3kg of denser materials such as steel, and the weight of the automobile decreases by 10% every time. , Fuel consumption can be reduced by 6%-8%. On the premise of ensuring the overall performance of the car, increasing the use of plastic materials can effectively reduce the weight of the vehicle, reduce vehicle emissions, improve fuel economy, and reduce vehicle manufacturing costs. The world’s largest automobile plastic bicycle consumption is Germany, which accounts for 15% of the total material consumption. According to the European level in 2005, the average bicycle consumption has reached 13%. However, China’s current bicycle plastic consumption is still higher than the level of developed countries. There is a big gap, and there is a great potential for improvement.

In China, major brands have begun to increase the application ratio of various lightweight materials such as alloys, super-strength steel, and engineering plastics in automotive products. At the beginning of this year, Ford announced the launch of the first F150 with a lightweight body, reducing the weight of the vehicle by 318 kg. Models such as MKX will also adopt related designs. However, compared with foreign brands, domestic self-owned brands have encountered considerable challenges on the road to lightweight. As foreign-funded material suppliers almost monopolize technology in some core components, the purchase price of independent brands remains high. Although some lightweight materials have obvious effects in reducing weight, they are expensive. For economical products, the cost of reducing the weight of the car by one kilogram is controlled within 20 yuan is an acceptable range.

At present, the price of synthetic plastics compared with local material suppliers is several thousand yuan per ton, and the average increase in cost per kilogram is several tens of yuan. The products of local material suppliers are mainly used in bumpers, fenders, wheel covers and other components. In the supply of lightweight materials for core parts such as steering knuckles and chassis suspension, they are basically supplied by foreign companies such as Bayer, BASF, and DuPont. monopoly”. For example, Bayer’s polyurethane composite materials and polycarbonate plastics can provide materials for car windows and new energy lithium batteries, while BASF’s long glass fiber materials are mainly used for engine suspensions and interior shock-resistant components. With increasingly stringent policies, self-owned brand car companies will still face severe challenges in the weak links in the automotive industry chain such as material supply and lightweight design. The sales volume and capital of self-owned brand companies have no advantages compared with foreign capital. At present, some companies represented by Chery Automobile have begun to cooperate with parts suppliers, lightweight materials suppliers and auto companies from the early stage of research and development.
