Aluminum Crank Case

Aluminium Crankcase Manufacturing

Precision-Engineered Power Unit Casings
The aluminium crank case, or power unit casing, is a critical component that houses and protects the internal elements of a motorcycle engine.
Typically crafted from aluminium alloy, it provides an ideal balance of strength, durability, and lightweight design, ensuring performance and longevity under demanding operational conditions.

Advantages of Aluminium Crankcases

• Lightweight Efficiency: Significantly reduces the engine’s overall weight, enhancing acceleration and fuel efficiency.
• Corrosion Resistance: Provides long-lasting protection against moisture and environmental exposure.
• Superior Thermal Management: Promotes heat dissipation, helping to maintain optimal engine temperatures.
• Robust Structural Design: Engineered to withstand mechanical stress and prevent cracking or deformation during operation.

Manufacturing Excellence at DSW

As a leading crankcase manufacturer, DSW specialises in producing aluminium crankcases using advanced, high-pressure die-casting techniques.
This method ensures consistent quality, excellent dimensional accuracy, and smooth surface finishes suitable for high-volume production.

Our manufacturing process includes:

• Tooling and Mould Design: Bespoke tooling is created based on each engine’s specifications, ensuring precise fitment with crankshafts, cylinders, and associated parts.
• High-Pressure Die Casting: Molten aluminium alloy is injected into steel moulds at high pressure, yielding dense, low-porosity castings with exceptional integrity.
• Heat Treatment: Post-casting thermal processing enhances the final product’s mechanical properties and fatigue resistance.
• Precision CNC Machining: Critical surfaces are accurately machined to tight tolerances, ensuring compatibility with engine components.
• Comprehensive Quality Control: Each power unit casing undergoes thorough dimensional checks and visual inspections to meet stringent quality standards.
