Precision Engineered Motor Housing Solutions - Durable & Efficient

As the motor housing segment rapidly evolves in automotive and industrial sectors, products like the Bottom Shell are setting new benchmarks for durability, efficiency, and design innovation. With an ever-increasing focus on engine oil pan, automobile oil pan, and components such as the engine sump and baffled oil pan, OEMs and Tier 1 suppliers demand exceptional technical performance, cost-efficiency, and customized solutions for diverse application environments.

• Automotive lightweighting: According to Statista 2023, the global motor housing & oil pan market is projected to reach USD 6.7 billion by 2027, driven by lightweight cast aluminum solutions—growth CAGR at 5.3% (2022-2027).
• Environmental compliance: Rapid transition towards stricter ISO 14001:2015 and SAE J431 standards for automotive castings, necessitating advanced materials and eco-friendly manufacturing.
• Application Diversification: Use of automobile oil pan and engine sump expands from automotive to petrochemical, metallurgical, renewable energy, and marine sectors.

A premium motor housing (alternately Bottom Shell) not only acts as a protective enclosure but also optimizes thermal management, oil retention, and vibration damping. Key design challenges:

• Corrosion resistance against aggressive lubricants and environmental agents
• Excellent sealing (conforms to ANSI B16.5 standards)
• Fatigue & impact resistance—prolonged lifetime above 3 million cycles
• Optimized surface roughness (Ra < 1.6 µm) for sealing & oil flow
