Why Water Glass Sand Casting is Ideal for Compression Ring?

High-speed trains travel across fields, mountains, and bridges. The safety and reliability of every part are crucial. As a professional foundry focused on railway parts, we use the efficient and eco-friendly Water Glass Sand Casting process to produce high-quality, precise key components like Stator Compression Ring, contributing to global railway safety.

1. Stator Compression Ring is the Core Skeleton of the Traction Motor

At first glance, the Stator Compression Ring looks very simple, but it actually, it is actually very important, it is essential “core skeleton” in railway traction motors. In order to clamp and secure the motor’s stator core, allowing it to withstand strong forces and intense vibrations during the train’s running at very high speeds.

A high-quality Stator Compression Ring ensures smooth motor function, reduces vibration and noise, maintains electromagnetic performance, lowers energy loss, and provides long service life. Since EMU motors work in various conditions, reliable performance is critical.

For railway parts that demand top safety and efficiency, the Stator Compression Ring’s quality directly affects the traction system’s overall performance.

2. Our Key Advantage: Water Glass Sand Casting Process

Among different casting methods, why do we choose Water Glass Sand Casting (also called CO₂ sand casting)? Because it meets both quality and environmental needs for high-speed railway parts.

2.1. High Precision and Quality

The Water Glass Sand Casting method uses water glass, which is also called sodium silicate bonded sand, as the mould to do casting. It is non-toxic and eco-friendly. With precise control, the sand mold hardens quickly, offering high strength and accurate shape. With these character, this green technology is an ideal method for large, complex, high-quality castings. It has become our primary process for making key railway parts like Stator Compression Rings, heavy bogies, structural components, and locomotive end covers. This ensures better structural integrity and operational reliability from the start.

Water Glass Sand Casting provides high mold hardness with little deformation. It produces Stator Compression Rings with smooth surfaces and exact sizes. This greatly reduces later machining work, improves quality, cuts costs, and offers good value.

2.2. Excellent Internal Integrity

This method greatly lowers defects such as blowholes and sand inclusions. It guarantees that every Stator Compression Ring has a dense internal structure, high strength, and stability.

2.3. Green and Eco-Friendly Production

Compared to older processes, Water Glass Sand Casting creates no strong odors and less smoke. This matches modern manufacturing’s environmental standards. We are committed to offering green solutions to our customers.

3. Our Products made by Water Sand Casting Technology
