Unveiling the Power of Our Casting Process Portfolio

A Full Spectrum of Aluminum & Alloy Casting Technologies

YICHOU offers a complete range of casting processes to suit different production volumes, part sizes, and performance requirements:

High-Pressure Die Casting (HPDC): Ideal for mass production of thin-walled, complex-shaped aluminum, zinc, and magnesium alloy parts. Our high-pressure machines deliver excellent dimensional accuracy, smooth surfaces, and high production efficiency, making them perfect for automotive, electronics, and consumer goods applications.
Low-Pressure Die Casting (LPDC): Specifically designed for aluminum alloys, this process uses pressurized air (0.2–0.7 bar) to gently fill the mold from below. The result? Dense, porosity-free castings with superior mechanical properties and excellent pressure tightness—ideal for automotive wheels, cylinder heads, and structural components requiring high integrity.
Gravity Die Casting (Permanent Mold Casting): Using gravity to fill reusable metal molds, this process delivers parts with fine grain structure, good mechanical strength, and smooth surfaces. It's particularly suitable for medium-volume production of aluminum components such as chassis parts, brake calipers, and industrial fittings where cost-effectiveness and quality balance is key.
Vacuum Die Casting: By actively removing air from the die cavity before and during injection, this process virtually eliminates gas porosity, enabling heat treatment (T6) of castings and producing parts with exceptional weldability and structural reliability—critical for aerospace and high-safety applications.
Sand Casting & Low-Pressure Sand Casting: For large, heavy, or low-volume parts, our sand casting capabilities—including low-pressure sand casting—offer unmatched flexibility in size and alloy selection, handling components up to 2 meters with robust mechanical properties.

Revolutionizing Parts Manufacturing for Diverse Industries

Our integrated casting processes redefine parts manufacturing by combining precision casting with machining centers, welding, heat treatment, and surface finishing. This synergy results in parts that exhibit superior quality, durability, and accuracy, all within a staggering 2-meter size range. The versatility of our processes ensures that your parts not only meet but exceed expectations—whether you need 100 units or 100,000.

Unparalleled Material Compatibility

Versatility Meets Excellence

YICHOU's casting processes boast compatibility with a wide array of materials, including but not limited to:

Aluminum Alloys: A356, ADC10, ADC12, A380, 6061, 7075, and custom alloys
Zinc Alloys: Zamak 3, Zamak 5, Zamak 7
Magnesium Alloys: AZ91D, AM60B

Frequently Asked Questions

Your Queries, Answered

Q: What makes YICHOU's casting processes stand out?
A: YICHOU offers a comprehensive casting technology portfolio—high-pressure, low-pressure, gravity, vacuum, and sand casting—all under one roof. This allows us to recommend and implement the optimal process for your part geometry, volume, and performance requirements, with integrated post-processing and surface finishing for a true turnkey solution.

Q: Can you accommodate large parts?
A: Absolutely! Our casting processes—especially low-pressure sand casting and gravity casting—can handle parts within a 2-meter size range, ensuring versatility for various industrial applications.

Q: Which materials work best with your casting processes?
A: Our processes are compatible with a wide range of materials including aluminum alloys (A356, ADC12, A380), zinc alloys (Zamak series), magnesium alloys, copper alloys, and iron/steel for sand casting. We'll help you select the ideal material for your application.

Q: How do you ensure surface quality?
A: Our processes are meticulously designed for excellent as-cast surface finishes, and we offer extensive post-casting surface treatments including shot blasting, polishing, anodizing, powder coating, and painting to achieve flawless results.

Q: Can I customize the structural appearance of my parts?
A: Yes—YICHOU's casting processes allow complete customization of geometry, wall thickness, ribbing patterns, and surface textures, enabling you to achieve precisely the structural design and aesthetic you envision.

Q: What are the differences between high-pressure, low-pressure, and gravity casting?
A: High-pressure die casting is best for high-volume, thin-walled parts with tight tolerances. Low-pressure die casting produces dense, heat-treatable components with excellent pressure tightness. Gravity die casting offers a cost-effective middle-ground for medium volumes with good mechanical properties. We'll guide you to the right process for your project.

Q: Can low-pressure and vacuum castings be heat-treated?
A: Yes! Because these processes minimize porosity, the castings can undergo T5 or T6 heat treatment to significantly enhance strength and hardness—something not typically possible with conventional high-pressure die casting.
