Shaanxi Xixian New Area Zhongcheng Machinery Manufacturing Co., Ltd. presents its precision-engineered Polyurethane Screen Wedge, a critical fastening accessory designed for firm shaker screen locking and fixing in drilling solid control systems. Operating across a 6,300-square-meter production facility since 2015, we deliver standard locking structures with multiple models compatible with different shaker equipment, including ZJ90, ZJ70, ZJ50, and XJ series rigs. Our wedges provide firm locking with anti-loosening and anti-displacement capabilities under high-vibration conditions, widely deployed in onshore and offshore drilling operations. Backed by ISO 9001/14001/45001 certifications and approved by HSE, TÜV, and BV, we support model customization with factory-direct supply and comprehensive technical support.
Traditional wooden or rubber wedges fail quickly in demanding drilling environments. Our Polyurethane Screen Wedge eliminates these pain points through advanced thermoset elastomer construction.
You get consistent clamping force that prevents screen panel migration during high-frequency operation. The material resists rot, swelling, and splintering—common failures in conventional fasteners.
The unique "memory" effect maintains tensioning force even under fluctuating temperatures. This ensures your screen panels stay firmly positioned throughout extended drilling cycles.
Unlike inferior alternatives, our wedges withstand wet, corrosive conditions without hydrolysis or degradation. Your equipment operates reliably in both onshore mud systems and offshore marine environments.

Precision Compatibility Across Equipment Types
We offer various wedge configurations tailored to different shaker models. Each design ensures perfect structural fit for your specific equipment.
Your installation process becomes straightforward. No forced fitting or frame damage risks.
Outstanding Durability Under Extreme Stress
Manufactured from wear-resistant materials, these wedges endure extreme mechanical stress. They maintain structural integrity through thousands of vibration cycles.
Testing includes DIN 53516 abrasion resistance and comprehensive tensile evaluation. You receive components proven to last in the harshest conditions.
Efficient Maintenance Operations
The streamlined design allows quick installation and replacement. You reduce equipment downtime significantly during screen panel changes.
Thanks to high rebound resilience and low compression set, wedges can be reused for multiple panel cycles. This lowers your operational costs.
Wide Application in Challenging Environments
Proven performance spans iron ore wet screening, coal preparation plants, and aggregate crushing operations. The wedges absorb impact from falling materials while protecting screen frames.
In offshore drilling, they resist marine corrosion and salt spray. Your equipment maintains reliability regardless of location.
Solid Control Systems for Drilling Operations
Our Polyurethane Screen Wedge secures shaker screen panels in mud circulation systems. As drilling fluid passes through vibrating screens, wedges maintain panel tension against heavy slurry loads.
You prevent fine particle bypass that compromises drilling efficiency. The firm locking mechanism withstands continuous high-G forces.
Coal and Mineral Processing Plants
In dewatering screens operating at high frequencies, wedges keep panels tightly fixed. They prevent the loosening that causes production losses.
Your coal preparation or mineral processing line maintains optimal material stratification. Screen panels stay aligned for accurate particle separation.
Onshore and Offshore Drilling Rigs
Whether you operate land-based rigs or offshore platforms, these wedges deliver consistent performance. They endure temperature fluctuations, humidity, and corrosive drilling fluids.
The UV-stabilized formulation prevents embrittlement during outdoor stockpiling. Your spare parts remain ready for deployment.
We understand that different operations require specific solutions. Our engineering team provides customized wedge designs based on your equipment specifications.
You choose hardness levels, dimensional tolerances, and structural configurations. We deliver products matching your exact requirements.
Comprehensive Service Package
Our production capacity of 200+ solid control systems annually ensures reliable supply. Strong logistics partnerships with Tianjin and Shanghai ports enable fast global delivery.
Every wedge undergoes rigorous inspection before shipment. Your components meet documented specifications across all parameters.
Inspection Protocol:
We maintain ISO 9001 quality management protocols throughout manufacturing. You receive products that perform reliably from the first installation.
Q: Why choose polyurethane over traditional wooden wedges?
A: PU wedges eliminate rot, swelling, and splintering problems. Their memory effect maintains tensioning force under temperature changes, providing superior long-term performance.
Q: How do I know when replacement is necessary?
A: Inspect for significant edge rounding or screen panel movement during operation. These signs indicate reduced clamping effectiveness requiring replacement.
Q: Can wedges be reused after screen panel changes?
A: Yes, high rebound resilience allows reuse for multiple cycles. Perform visual integrity checks before reinstallation to ensure continued performance.
Q: What hardness should I select?
A: Higher Shore A hardness (90-95A) provides rigid fastening for heavy-duty applications. Slightly lower hardness (85A) offers better vibration dampening for sensitive equipment.
Q: Are these wedges suitable for outdoor storage?
A: Our UV-stabilized formulation prevents embrittlement during outdoor stockpiling. Store in covered areas when possible for extended service life.
Q: What makes your wedges corrosion-resistant?
A: Polyurethane chemistry inherently resists oil, mud, and salt water. Unlike metal fasteners, they won't rust or degrade in marine environments.

We had an urgent need for a custom mud zero-discharge system for a coalbed methane project, and Zhongcheng delivered. Their engineering team locked in the designand shipped the full system in 45 days, and it integrated perfectly with our existing ZJ50 rig. On-site commissioning even finished ahead of schedule. Their technical know-how and speed are exactly what we need for time-sensitive projects.
