The factors that accelerate the automotive industry towards achieving sustainability goals include emission control mandates and the EV (electrical vehicle) movement. The backbone of this industry shift is the aluminum die casting process which not only enables the production of lightweight and high performing parts, it also lowers overall costs. With the development of aluminum die casting, a new method of production that allows achieving high levels of virtuous efficiency has emerged.
Light Weight: The Strengths of Modern Electrical Cars
Aluminum die casting is crucial for achieving the strength to weight ratio required in many modern vehicles. Primary components are:
1. Bloques de motores y Carcasas de Transmisiones
Due to being almost 3 times lighter than steel, aluminum’s strength to weight ratio is quite favorable. Alongside fuel-efficient cars, low CO2 emitting vehicles are now common in modern society. Die-casted engine blocks are capable of reducing vehicle weight upto 40%.
2. Chassis Structural Parts
Control Arms & Steering Knuckles: Die-cast aluminum parts withstand extreme stress while resisting corrosion.
Suspension Components: Lighter chassis parts improve handling and reduce wear on tires and brakes.
3. Body-in-White (BIW) Components
Door Frames & Crossmembers: Thin-walled, high-strength castings cut body weight by 15–20%, enhancing crash safety.
EV Battery Trays & E-Drive Housings: Aluminum’s thermal conductivity ensures optimal battery temperature management, extending EV range by 8–12%.
Integrated Aluminum Die Casting: Revolutionizing Vehicle Assembly
Pioneered by Tesla, integrated die casting replaces hundreds of welded parts with single-piece structures, streamlining production and enhancing performance.
1. Tesla’s Giga Press Breakthrough
Using 6,000–12,000-ton mega presses, Tesla produces rear underbodies as one piece, slashing part counts from 70+ components to 1–2.
Benefits:
30% faster production
20% lower costs
40% higher structural rigidity
2. Implications for EV Manufacturers
Simplified Assembly: Fewer welding robots and fasteners reduce factory footprint.
Enhanced Safety: Eliminating weld points minimizes failure risks in collisions.
Design Flexibility: Complex geometries improve aerodynamics and cabin space.
