How High Pressure Ceramic Casting Enhances Bathroom Sink Production Efficiency and Quality

In today’s time-pressured and design-driven sanitary ware industry, there is increasing pressure on manufacturers to create high-quality ceramic bathroom sinks that are not only aesthetically pleasing but also structurally reliable, while ensuring efficient and scalable production. One breakthrough technology that addresses all these needs is high-pressure ceramic casting.

At Hanyu, we have embraced this advanced technique to transform the way we produce bathroom sinks. In this article, we explain how high-pressure casting is done and why it is so important to greater production efficiency and product quality.

What Is High Pressure Ceramic Casting?

High pressure ceramic casting, or high pressure slip casting, is a relatively new forming process which pushes ceramic slurry (or slip) into a closed, high-strength mold under pressure. Unlike gravity-based traditional casting, this process uses air or hydraulic pressure to fill the mold quickly and precisely.

Brief description of the working principle:

• Use of porous plaster or resin molds
• The slurry is pressed into the mold cavity by pressure (generally 2~15 bar).
• Moisture in the slurry is discharged through the mold, and the ceramic blank is formed quickly.
• Shorter molding time, long mold life, suitable for mass production

Benefits for Bathroom Sink Production

1. Improved Production Efficiency

One of the greatest advantages of high-pressure ceramic casting is its speed. A process that traditionally took hours can now be completed in minutes. This means:

• Faster cycle times
• More units produced per shift
• Shorter lead times for bulk orders

This is a game-changer for large-scale bathroom sink production, especially for wholesale, OEM, and project-based orders.

2. Higher Dimensional Accuracy

High pressure ceramic casting enables tight control over wall thickness, symmetry, and surface smoothness. This is especially important for bathroom sink models that require perfect integration with countertops, such as:

• Undermount basins
• Inset or semi-recessed basins
• Wall-mounted designs

With consistent casting quality, there’s less need for manual trimming or surface correction.

3. Reduced Defect Rates

Because the process is automated and pressure-driven, it minimizes common issues like:

• Air bubbles
• Warping
• Cracking during drying

As a result, manufacturers enjoy higher yields, and customers receive more reliable products.

4. Supports Complex and Modern Designs

Today’s market demands more than just functionality—consumers and designers want stylish, unique bathroom sinks in various textures and finishes. High pressure ceramic casting supports:

• Sharp edges and thin profiles
• Non-traditional shapes (oval, square, minimalist)
• Decorative finishes like matte, marble-effect, and electroplated coatings

This makes it ideal for producing premium collections and custom bathroom sink lines.

5. Long-Term Cost Savings

Though the initial investment in high pressure ceramic casting equipment is higher, the long-term savings come from:

• Longer mold life (resin molds can last hundreds of cycles)
• Less material waste
• Lower labor costs due to automation

This helps maintain competitive pricing without compromising on quality.

Future Trend: Deep Integration of Automation + High Pressure Ceramic Casting

More and more ceramic manufacturers are combining high-pressure casting with automation equipment, robot arms, etc. to realize full-process automated production. 羽生 is an active practitioner of this trend, we continue to invest in research and development, and optimize the process, to provide our customers with higher quality and more reliable ceramic sink products.

Why It Matters for Your Business

For bathroom brands, hotel developers, or sanitary ware distributors, high pressure ceramic casting brings significant value:

• Reliable bulk production with fast lead times
• Higher quality and uniformity, reducing post-processing work
• Design flexibility to match changing market trends
• Confidence in performance, especially for wall-hung or under-mount basins requiring precise installation
