Prototyping for new energy vehicle’s cast aluminium chassis

Before Tesla making cast aluminium chassis production, they also need a prototyping progress to make cast aluminium, and then combined with CNC machining, the completely working procedure for Tesla’s chassis is done. New energy vehicles companies choose using cast aluminium, so it’s vital necessary for them to have integrated molding prototypes manufacturer. In this case, Industrial-Man is absolutely have the capacity.

2、Advantages for making cast aluminium prototypes of electric vehicle’s chassis

The aluminum integral chassis of the automobile is adopted with sand casting process. As chassis’s prototypes require short working hours, it’s not recommend using large pieces of aluminium sheet while CNC machining. In that way it’s could save more raw material and speed up the development cycle during the prototyping stage .  After casting parts being formed, we’ll use a large gantry five-axis CNC or a large horizontal milling machine processing equipment to carry out the second CNC precision machining. Aiming at the mounting hole of the chassis and the key position of the assembly, further precision treatment process is made to complete the casting prototypes for the chassis of electric vehicle. The above mentioned are the unique advantages of using cast aluminium alloy casting prototypes.

3、Advanced automobile chassis’s prototypes are more valuable

Prototype experts hold the view that the processing technology of prototypes for new energy vehicle chassis is more difficult than that of aluminum alloy casting mass-produced chassis. In terms of the quantity of a single piece, the unit price of prototyping chassis is 10 times higher than that of mass-casting produced chassis. Starting with two different manufacturing processes and two different values, but both of them are of same product and theoretical value. It has to be admitted that aluminium chassis prototyping process is indeed more difficult than the technical difficulties of mass-produced chassis.

4、Application of making automobile chassis’s prototypes

It is difficult for non-professionals to understand the purpose and significance of making prototypes of automobile chassis with prototyping. In fact, it’s a very common thing for the automobile industry using prototyping. There are two main roles for integrated molding prototypes of aluminium automobile chassis: 1. The weight and shape of the prototyping chassis parts are basically in accordance with the actual production cars; 2. In the course of various certificating and testing, especially the integration of battery chassis, this aluminium-integrated prototypes are same as the mass-produces chassis, they all have excellent heat dissipation performance, and the test result are not distorted, the aluminium chassis of the follow-up mass-produced car is quite safe to use.

5、Capacity of making aluminium automobiles chassis by Industrial-Man

New energy vehicle chassis integrated casting molding/ Aluminium alloy casting process/ prototyping/ small batch trial-manufacturing and so on. It is no exaggeration to say that Industrial-Man had sufficient processing capabilities at this stage, especially the secondary CNC machining after casting, all services are available here. We’re not only having the largest five-axis gantry CNC machine(Specification of 8 meters long, 4 meters wide, and 2 meters high for actual processing size), meanwhile Industrial-Man has more 300 sets of equipment that can support various processing, which can fully meet the different new energy vehicle aluminium alloy chassis trial-production capacity.
