Promoting lightweight automotive parts requires government support
The fuel consumption of a car is mainly determined by the engine displacement and the total weight of the car itself. While maintaining the overall quality, performance, and cost of the car, reducing the weight of the car itself can increase output power, reduce noise, improve handling, enhance reliability, increase vehicle speed, reduce fuel consumption, reduce exhaust emissions, and increase safety. . Some research results show that if the vehicle weight is reduced by 10%, the vehicle fuel efficiency can be increased by 6% to 8%. The relevant experts pointed out: "If the weight of all cars in the country is reduced by an average of 25%, then fuel consumption can be reduced by 13%. The country can save about 300 million barrels of oil a year and emit about 2.4 billion tons of carbon dioxide emissions." Obviously, the car is light Quantification plays a major role in the implementation of the "energy saving and emission reduction" strategy by the country. Lightweight cars are mainly reflected in lightweight components. What are the conditions for the development, production, promotion and application of domestic lightweight auto parts? With this question, the reporter interviewed several representative auto parts companies. Lightweight (energy saving and environmental protection) auto parts products are the main force for the transformation and upgrading of Hubei Full Machinery Group. On March 5, 2014, Song Yicun, deputy general manager of Hubei Quanli Machinery Group, said in an interview with reporters: “We are in line with the development direction of the national automobile industry and rely on the advantages of supporting cooperation with a number of global 500 companies. Absorb advanced technology and technology from developed countries and cooperate with Hubei University of Technology to successfully develop more than 10 patented automotive lightweight parts and components.†At present, Hubei Full Machinery Group has three series of lightweight auto parts products: First, the hub brake drum series products, with a weight reduction of 20%, integrated manufacturing and good safety features, large quantities of supporting the United States and Europe Commercial vehicles; second, internal- and secondary-brake heat-dissipation brake discs, featuring high strength, light weight, good dynamic balance, and sensitive and safe brakes; large-scale matching cars and heavy-duty commercial vehicles; and third, engine series. Shell and aluminum alloy filters and other products, with high strength, light weight, excellent performance characteristics. The promotion and application of lightweight auto parts in China needs government support. Song Yicun urged: “The state should introduce a guidebook for lightweighting of automobiles as early as possible†to guide enterprises and research institutes to strengthen cooperation; policy support and encouragement should be intensified to promote the industrialization of lightweight parts and components as soon as possible; at the same time, domestic The company that develops and produces lightweight parts and components will strengthen technical cooperation with its counterparts in developed countries to promote the healthy development of domestic lightweight parts and components industry.†Aluminum alloy wheels are lightweight components. The car equipped with aluminum alloy wheels can reduce fuel consumption, increase payload, reduce exhaust emissions, reduce brake loss, and reduce maintenance costs. It has advantages such as high recovery and high returns. It is particularly worth emphasizing that the tire wear rate can be reduced by 30% to 40%. Some developed countries have made remarkable achievements in selecting aluminum alloy rims from the viewpoint of protecting the environment, reducing the pressure of energy tension and improving the efficiency of vehicle operations. In developed countries, the fitting ratio of aluminum alloy wheels on commercial vehicles now exceeds 70%. Alcoa is the world's aluminum alloy wheel industry leader, has the most aluminum alloy wheel product specifications, in the world of commercial vehicle aluminum alloy wheel market share of more than 75%. European lightweight commercial vehicles are taking the lead in the world. Aluminum alloy wheels are the mainstream configuration of European long-distance standard logistics transport vehicles. Constrained by many factors, it is still a long process for China to promote aluminum alloy rims. NORD Wheel Manufacturing Co., Ltd. is adhering to the philosophy of “respecting the people, the virtue and the world†and is specialized in the development, production and sales of high-performance wheel hub products. Developed aluminum alloy wheels for low-pressure cast trucks and aluminum wheel hubs for passenger cars. We have aluminum alloy wheels for all types of commercial vehicles. On March 6, 2014, Li Mengjun, Marketing Director of Marketing Center of Nord Hub Manufacturing Co., Ltd. said in an interview: “Because high-priced aluminum alloy wheels have not become the standard for domestic vehicles, many domestic customers have not yet known The aluminum alloy hub has the advantages of high recovery, high returns, etc. Therefore, only a small number of customers in the country have actively requested the aluminum alloy wheels for the entire vehicle, and the fitting ratio of the aluminum alloy wheels on commercial vehicles in China is less than 1%.†Lianyungang Gem Heavy Industry Equipment Co., Ltd. is a professional manufacturer of forged aluminum wheels for passenger cars, cars and heavy-duty trucks, and has a strong technical team. It has established joint technology development centers with well-known companies in the United States, Japan, and Europe forged aluminum wheels industries. Internationalized management mechanism. Lianyungang Gem Heavy Industry Equipment Co., Ltd. official said in an interview with reporters: “At present, our company’s annual production and sales volume of lightweight parts and components is 500,000 sets. Compared with the annual production capacity of our company’s actual lightweight components, the gap is very high. The main reason is that, for a long time, domestic consumers have always been pursuing the concept of low-cost consumption, resulting in very little demand for lightweight aluminum forged wheels. The promotion of aluminum alloy rims is a general trend. With the vigorous development of the domestic transportation industry and the increasing efforts in energy conservation and emission reduction policies, aluminum alloy wheels will surely gain more customer recognition. The relevant person in charge of Lianyungang Gem Heavy Industry Equipment Co., Ltd estimated: “In two to three years, the domestic consumer perception will change, and our aluminum alloy wheel production and sales business will be able to do it.†CNC Machining is a manufacturing process where computers run programs that control how the machines will manufacture parts. These CNC Programs using CNC Software can control everything from the motions the machine makes to spindle speed, turning coolant on or off, and much more. The computer language used to program CNC Machines is called [G-Code". To make it easier, g-code is seldom written by hand. Instead, visual programming tools called CAM Software are used to create the g-code.
There are many different kinds of CNC Machine including 3D Printers, CNC Mills, CNC Lathes, CNC Lasers, Water Jets, Electronic Discharge Machines (EDM`s), CNC Routers, and more.
Benefits of CNC machining
1) Lower labour costs
2) CNC increases production choices
3) No need for extensive skills or experience
4) Reproduce your product range endless times
5) No costly prototypes required
We have made many aluminum parts by CNC process, these parts are commonly used in industry, automotive, consumer, electrical field. specially, we ever made kinds of componets that used in automotive field and have the 2nd process treatment( such as anodization, Powder Coating, spary coating), we can ensure the best quality sample with lower price to you to make sure you are ok with sample and glad for production.

Machined parts are often chosen when manufacturing must result in high precision or quality, or when the materials are particularly tough and hard to work.
