Our Capabilities

Integrated "Design-Cast-Machine" Solutions

We provide a one-stop, closed-loop solution that integrates design, casting, machining, and testing.

Massive Capacity: Backed by an annual capacity of 250,000 tons and a quality system aligned with ISO 9001 / EN 3834-2.

Flexible Delivery: From single prototypes to batches of 5,000 pieces. We handle large castings with a maximum single weight of up to 7 tons.

Advanced Simulation: Utilizing CAE solidification simulation technology, we optimize the casting process, improving the first-pass yield by 18%.

Custom Metallurgy: We offer customized high-strength Ni-Cr-Mo alloy formulations for wind power castings, increasing bench fatigue life by 30%.

Product Portfolio

Precision Engineering for Critical Wind Components

We specialize in thin-walled, irregularly shaped components, solving the industry's toughest manufacturing challenges.

1. Gearbox Housing

The Solution: 7-ton monolithic molding, ready for assembly immediately off the line.

The Challenge Solved: Overcoming shrinkage porosity in thin-walled oil passages and large-surface warping.

Our Tech: Digital simulation reduces shrinkage cavities by 50%; 5-axis machining ensures flatness far superior to industry standards.

2. Planet Carrier

The Solution:30% lighter weight with a 30% increase in lifespan.

The Challenge Solved: Preventing deformation in multi-hole positions and addressing short fatigue life.

Our Tech: Low-alloy formulation combined with in-mold cooling keeps deformation ≤0.15mm. Full CMM inspection guarantees Cpk ≥1.67.

3. Generator End Cap

The Solution: High-speed bearing with "Zero Runout".

The Challenge Solved: Controlling roundness difficulties caused by stress release deformation.

Our Tech: A closed-loop process of Casting → Aging → Machining → Dynamic Balancing (48h) improves roundness by 50% and passes audit in one go.

4. Front Bearing Cap

The Solution: Sealing surfaces that are leak-proof for life.

The Challenge Solved: Improving rough sealing grooves and poor salt spray resistance (typically failing under 1,000 hours).

Our Tech: Specialized machining achieves Ra ≤1.2µm; Marine-grade coating withstands 1,200 hours of salt spray, doubling the maintenance cycle.

5. Generator Housing (Shell)

The Solution: Large volume with low vibration.

The Challenge Solved: Uneven wall thickness leading to cracks and difficulties in molding cooling fins.

Our Tech:3D printed integral sand molds control wall thickness to ±1mm; Excitation aging ensures vibration attenuation leads the industry.

6. Gearbox End Cap

The Solution: 10-minute quick change with 100% interchangeability.

The Challenge Solved: Hole position deviation causing sealing strip leaks.

Our Tech: Flexible lines + online probes compress positional tolerance by 20%; Airtightness tested to 0.6MPa with zero leakage, enabling "plug-and-play" batch consistency.
