Ġdid Enerġija Jaċċellera Ħafif Vettura Żvilupp ; Integrat Die-Casting As A Ċavetta Għodda

 

In October 2020, the Energy-Saving and New Energy Vehicle Technology Roadmap 2.0, organized and compiled by the China Society of Automotive Engineers, was released, which put forward requirements for the fuel consumption per 100 kilometers of various types of vehicles. It is expected that in 2030, new energy vehicles in my country will account for 40% of the total sales, and the fuel consumption of passenger cars per 100 kilometers will reach 3.2L, responding to the "dual carbon" goal. From the perspective of fuel vehicles, the average fuel consumption of a car is positively correlated with the weight of the whole vehicle, and the lightweighting of the car has a positive role in reducing the fuel consumption of traditional vehicles. According to research, for every 10% reduction in the weight of the car, a maximum of 5-10% fuel savings can be achieved; for every 100 kg reduction in the curb weight of the car, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters.

 

Fi recent years, the penetration rate of new energy vehicles in my country has continued to rise, but "range anxiety" still limits consumers from purchasing new energy vehicles. Generally speaking, a traditional fuel vehicle can travel more than 500 kilometers after filling up with gas, filwaqt li the range of most electric vehicles is around 300-500 kilometers, li still leaves a gap.

 

 

 

 

New enerġija vetturi jistgħu solvew range ansjetà in the following ways:

 

(1) Improve batterija enerġija densità. "Made in my country 2025" clearly jiddefinixxi l-iżvilupp pjan għal power lithium batteriji: in 2020, the battery energy density will reach 300Wh/kg; in 2025, the battery energy density will reach 400Wh/kg; in 2030, the battery energy density will reach 500Wh/kg.

 

(2) Żieda in-numru ta' batterija pakketti u reduce piż. Imqabbel ma tradizzjonali enerġija vetturi, ġdid enerġija vetturi huma spiss 10% itqal mill fjuwil vetturi due to tagħhom tliet elettriċi sistema. Żied in-numru ta' batterija pakketti jista' żieda il-firxa, iżda it it total piż of the battery pack of the battery pack is 900 kg, accounting for 42.7% of the total vehicle mass. Therefore, it can be seen that one of the important modi biex iżżid il-firxa is biex tnaqqas il - piż ta ' il- vettura .

 

Ħfief ta ' karozzi huwa a maġġuri tendenza fi l-iżvilupp ta' il - karozzi industrija. Il mogħdijiet biex tikseb ħfief prinċipalment jinkludu materjali , proċessi, u strutturi. Piż jista ' ikun imnaqqas f' multipli partijiet , inkluż power, korp, chassis, intern u barra trim.

 

Skond għal the "China Automobile Lightweight Industry Development Trend Analysis and Investment Prospect Forecast Report (2023-2030)" released by Guanyan Report Network, at present, the lightweight directions of automobile companies include:

1. Using Aluminju Liga Minflok OF Steel in Automobile Chassis, Power, Body, Battery Box u oħrajn Partijiet;

2. Uża plastik minflok ta ' azzar għal intern u barra trims;

3. billi tuża integrat die-casting proċess. Ħfief manifattura tista ' tinkiseb fi kull link ta' karozzi partijiet, u mainstream partijiet kumpaniji at home u barra huma impenjati għal ħfief manifattura.

 

 

Aluminju liga huwa ċavetta materjal għal ħfief karozzi.

Aluminum alloy is one of the best lightweight materials at this stage. Currently, many mainstream models use all-aluminum bodies, and most of the front and rear suspension materials are also made of aluminum alloy. The degree of aluminumization is getting higher and higher, and lightweight manufacturing is achieved to the greatest extent.

 

At present, the conversion rate of aluminum used in chassis, body, brake system, etc. is low. In the next ten years, the penetration rate of aluminum used in many major parts of automobiles will increase significantly. The "Energy Conservation and New Energy Technology Roadmap" of the Ministry of Industry and Information Technology propos that the target of aluminum consumption per vehicle in my country in 2025/2030 is 250kg% 2fvehicle and 350kg/vehicle. The aluminum alloy consumption per vehicle in 2030 is expected to double comcompared with 2021.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Integrat die casting is a avvanzat-edge technology for lightweighting, and first-mover companies will build high barriers.

 

Traditional automobile manufacturing consists of four major processes: stamping, welding, painting, and assembly. Among them, stamping is to press metal sheets into various components required for the car body, and then use welding or riveting to manufacture large aluminum parts. Integrated die-casting uses a large-tonnage die-casting machine to change stamping and welding into die-casting, combining the first two steps into one, highly integrating multiple separate and scattered parts, and directly casting large parts.

 

Hemm tnejn negozju mudelli għal integrat die-casting. One is the self-developed model: the OEM direttament purchases die-casting machines, materials, molds and other materials, and builds its own factory to produce die-castings. Representative car companies include Tesla, Xiaopeng and Volvo. The other is the procurement model: the OEM direttament purchases die-castings from die-casting manufacturers, and the die-casting manufacturers purchase related materials and deliver the die-castings to the die-castings to the OEM after production. Representative car companies include Weilai and Ideal. In the long run, due to the high cost of self-built factories and production lines for OEMs, and the fact that car sales may become a suppressing factor on capacity utilization, the procurement model is expected to become the long-term mainstream.

 

Minn il-perspettiva ta ' l industrijali katina , il upstream ta' il integrat die-casting industrija katina huwa il die-casting magna, materjal u moffa manifatturi, il - midstream huwa l- aluminju liga die-casting pjanti u awto-żviluppati OEMs, u il downstream huwa ix-xiri OEMs.

 

Minn il-perspettiva ta' dħul barrieri, integrat die-casting ukoll has relatively high technical barriers, li se jkabbar l-ewwel vantaġġ tal-manifatturi.
