Optimizing Wire Part Layout Design for Peak Performance
We don't just supply ceramics; we engineer complete dewatering systems. Tailored forming table configurations designed to optimize drainage curves and enhance sheet formation.
Customized Drainage Curves
By analyzing your specific furnish, machine speed, and target paper grade, we calculate the optimal drainage profile. We design the spacing, angle, and width of forming boards and hydrofoil blades to control initial water removal, preventing sheet sealing and pinholes.
Vacuum Management
We engineer the layout of low-vacuum and high-vacuum suction boxes. Graduated vacuum zones prevent sudden pressure drops, maintaining fiber dispersion and improving sheet formation index while reducing overall power consumption of vacuum pumps.
Drag Load Reduction
Through advanced simulation, we design the contact surface area of the ceramic covers. Reducing friction between the forming fabric and the ceramic elements significantly minimizes drag load, leading to reduced drive motor power and extended fabric life.
State-of-the-Art Ceramic Materials for Extreme Wear Resistance
Engineered to withstand high speeds, chemical corrosion, and abrasive fillers. Our material systems guarantee ultra-long lifetimes under complex papermaking conditions.
Microcrystalline Alumina
Modified with composite additives, providing high density, uniform structure, and excellent wear resistance. Ideal for medium-speed paper machines and standard dewatering applications.
Zirconia-Toughened Alumina
Combines the hardness of alumina with the toughness of zirconia. Highly resistant to mechanical shock and micro-fractures, perfect for high-load forming boards and foil blades.
Reaction Bonded & Sintered
Offers extreme hardness (second only to diamond) and low friction coefficient. Provides exceptional lifetime under high-speed operation with highly abrasive fillers like CaCO₃.
Gas Pressured Sintered
The ultimate material for high-speed, wide paper machines. Features maximum fracture toughness, superior thermal shock resistance, and minimal wire wear.
Dewatering Elements & Ceramic Cleaner Cones
In the 1990s, Sinyo established its presence in the papermaking industry. In 1994, leveraging our comprehensive scientific platform, we undertook and completed the provincial project: "Development of Full Ceramic Panels for Paper Machine Vacuum Suction Boxes." This project passed provincial appraisal in 1995 and received the Shandong Province Science and Technology Progress First Class Award in 1997.
Using composite additive-modified microcrystalline corundum, we developed structured, segmented designs that fully satisfy the requirements of increasing paper machine speeds.
Additionally, our successfully developed ceramic cleaner cones offer high precision, impact resistance, wear resistance, corrosion resistance, and high fiber retention rates. They are available in over 30 series and 200+ specifications, serving advanced papermaking lines worldwide.
Forming Boards & Hydrofoils
Precision-ground blades with exact angles to control initial dewatering and enhance sheet formation.
Vacuum Suction Box Covers
Segmented designs engineered for thermal expansion and mechanical stability under high vacuum loads.
Ceramic Cleaner Cones
Highly wear-resistant cones designed to remove contaminants from pulp slurry efficiently.
Proven Success in High-Speed Paper Machines
Our projects at Taizhou Forest Paper and Quzhou Xianhe Special Paper mark significant milestones in replacing expensive imported ceramic elements.
5200mm Triple-Wire Packaging Paper Machine
In May 2016, the ceramic dewatering element project for Taizhou Forest Paper's 5200mm triple-wire packaging paper machine was successfully put into operation. Designed for a speed of 800m/min, the machine achieved a stable operating speed of 850m/min, with a peak speed of 921m/min.
- Daily production exceeded 1,000 tons with excellent sheet quality.
- Forming fabric life reached 125 days, outperforming imported brands by 38.9%.
- Reduced procurement costs by 33%.
- Saved the mill over 3.9 million RMB in capital and operating expenditures.
Cooperation with International OEMs
While maintaining a strong presence in the domestic mid-to-high-end markets, Sinyo's products are exported in bulk to the United States, Germany, Finland, Japan, South Korea, and many other countries.
As part of our global expansion strategy, we have strengthened our technical and commercial partnerships with world-renowned papermaking equipment OEMs:

Collaborative Research & Future Outlook
Sinyo collaborates actively with the Shandong Industrial Design Center and various universities to conduct joint research on wire part dewatering mechanisms. These studies provide solid theoretical support for quantitative dewatering on the forming table.
We focus on a problem-oriented approach, conducting in-depth material performance research on Alumina, Zirconia-Toughened Alumina (ZTA), Zirconia, Silicon Carbide, and Silicon Nitride. This ensures our ceramic components meet the complex and demanding operating conditions of modern paper mills.
Looking ahead, Sinyo will align closely with global papermaking trends. We are committed to providing customized services to help mills achieve energy conservation and consumption reduction. By focusing on high-end ceramic dewatering elements and cleaner cones, we continue to invest heavily in R&D, focusing on nitride materials, special high-temperature spray coatings, and large-scale, complex-shaped ceramic monoliths.
