Leierwo’s advantages in casting precision castings in the automotive manufacturing industry

Leierwo, with its ISO 9001 and IATF 16949-certified quality management system, meets the automotive industry’s stringent requirements for consistent performance and quality control. The company’s casting capabilities for materials such as alloy steel and carbon steel make it suitable for manufacturing key parts such as engine mounts, transmission housings, and brake system components. Furthermore, the company possesses CNC machining capabilities, enabling subsequent processing of precision castings to enhance dimensional accuracy and assembly compatibility, further meeting the high-standard processing requirements of automotive components.

Main material selection

Automotive parts require materials with excellent strength, toughness, fatigue resistance, weldability, and a certain degree of corrosion resistance, while also balancing lightweighting and cost-effectiveness. In precision casting, carbon steel and alloy steels are widely used due to their excellent mechanical properties and machinability.

Common Materials:
Carbon Steel Series:
1045: Excellent strength and toughness, suitable for structural parts such as shafts and connecting rods.
4130: A chromium-molybdenum alloy with excellent heat treatment properties, suitable for high-strength, fatigue-resistant components such as suspension systems and drive shafts.

Alloy Steel Series:
42CrMo (AISI 4140): High strength and toughness, suitable for key components such as gears, crankshafts, and camshafts.
35CrMo: Similar to 42CrMo, but with a slightly lower carbon content, suitable for components requiring excellent welding properties.
4140: Widely used in heavy-duty automotive parts such as shafts and chassis components.
Stainless Steel Series (for specific components)
304L/316L: Used in components requiring high corrosion resistance, such as exhaust systems and fuel systems.

Key casting service options

The automotive parts industry must balance mass production capacity, precision requirements, and cost control when choosing casting services. Three service categories each have their own focus:

Sand casting: This is the mainstream choice for automotive parts. Automotive parts are often mass-produced (e.g., engine blocks, chassis brackets, and wheel hubs). These parts have relatively regular shapes (without overly complex internal cavities or curved surfaces). Sand casting enables efficient mass production at a low cost, meeting the automotive industry’s demand for “large-scale standardization.”

Investment casting: This is suitable for critical parts with high precision and complex shapes, such as turbocharger blades and transmission gears. These parts must withstand high temperatures and high pressures, and require extremely high dimensional accuracy (e.g., blade curvature) and surface finish. The near-net-shape capabilities of investment casting reduce subsequent machining and ensure consistent performance.

CNC machining: This serves as a “precision supplement” to casting. Core automotive components (such as crankshafts and connecting rods) require strict dimensional tolerance control (such as shaft diameter tolerance +0.01mm). After sand or investment casting, key surfaces (such as connecting holes and locating grooves) are fine-machined through CNC machining to ensure assembly accuracy and operational stability.
