We supply complete water-stop board production lines engineered to produce waterproof barrier boards and joint sealing profiles used in construction, civil engineering and landscaping. Our machines extrude polymer-modified sheets and profiles (PVC, modified PE and polymer blends) with controlled thickness and surface finish for effective water-blocking, chemical resilience and long service life. I coordinate with customers to deliver lines that include high-capacity extruders, precision calendering sections and stable cooling systems to ensure board flatness and dimensional accuracy.
How is a Water-Stop Board Production Line manufactured?
A water-stop board production line integrates raw material feeding, single- or twin-screw extrusion, precision die and calender sets followed by controlled cooling and cutting. We specify dies and roller configurations based on board dimensions and required barrier performance; the process emphasizes consistent melt homogeneity, rapid cooling to avoid warp, and automated thickness control to meet stringent tolerances. Our lines can include embossing or lamination units to add textured surfaces or reinforcement layers for enhanced mechanical strength.
Our equipment is suitable for producing boards used in foundation waterproofing, tunnel segment sealing and expansion joint waterproofing. We also provide start-up training, spare parts and remote diagnostics to reduce commissioning time.

Product Description
plastic PVC water stopper making machine production line construction joint sealing plastic pvc water stopper making machine:
Overview:
Waterstops are produced from high-grade PVC/EVA/HDPE compounds. They are designed for sealing movement and construction joints in reinforced concrete structures.
Nomal size of pvc waterstop:
Width:150mm,200mm,250mm,300mm
Applications:
-plastic Waterstops, used in concrete for the sealing of construction and expansion joints, are embedded in concrete, across and along the joint, to form a continuous watertight diaphragm that prevents the passage of fluid through the joint.
- The many shapes centrally and externally placed allow lasting watertight seals in any grade of construction design.
- They are typically used in water retaining and excluding structure such as: Reservoirs, sew age tanks, dams, pools, basements, tunnels retaining walls, pits, partitions of elevators etc
Advantages
- The surface of Platic Waterstops has many edges enhances adhesive ability with concrete, preventing water corrosion.
- Full range of factory welded and fabricated intersection pieces to suit every need
- Easy to use on construction site.
High-Performance Water Stop Board Production Line Overview
Investing in a reliable Water Stop Board Production Line is essential. It helps manufacture durable, high-quality plastic waterstops for demanding construction and tunneling projects. As a core offering from Qingdao Zhongrui Plastic Machinery Co., Ltd., this extrusion equipment delivers high efficiency and stable performance. Designed for modern infrastructure demands, our machinery adapts seamlessly to various raw materials. While primarily optimized for PVC, the system easily processes PE or EVA. This ensures maximum versatility for diverse waterproofing applications.
Core Components of the Water Stop Board Production Line
The reliability of any extrusion system lies in its engineering and component quality. Our machinery features robust, precision-engineered parts designed to maximize output while minimizing downtime. By integrating advanced technology across every stage, we provide B2B buyers with consistent product quality and long-term operational stability.
Advanced Single and Double Screw Extruders
At the heart of the system is our advanced single or double screw extruder. We specifically tailor this unit for the material properties of PVC. The optimized screw design ensures excellent plasticization and uniform melting. This is critical for maintaining the structural integrity of the final product. Coupled with premium electrical components, the extruder guarantees energy efficiency, high output capacity, and stable continuous operation.
Precision Extrusion Die Head and Mold
The extrusion die head plays a pivotal role in shaping the profile with exact dimensional accuracy. Qingdao Zhongrui specializes in designing and manufacturing precision molds tailored to your specific project requirements. You may need standard profiles or specialized designs with integrated steel edges. Our customized die heads ensure a flawless finish and consistent material distribution.
Vacuum Calibration and Cooling System
To lock in the shape and ensure strict accuracy, the extruded profile passes through a state-of-the-art vacuum calibration unit. Utilizing a heavy-duty stainless steel flume and a powerful vacuum table, this system provides rapid, uniform cooling. This immediate temperature reduction prevents warping and shrinkage. It guarantees that the extruded board meets exact industry specifications.
Haul-off and Cutting Unit
The final stages of the production process rely on a synchronized haul-off and cutting unit. Our robust caterpillar haul-off machine delivers a stable, continuous pulling force without deforming the cooled profile. Following this, the automated cutting and winding unit ensures precise length control. This streamlines the transition from manufacturing to final product dispatch.

Applications of Extruded PVC Waterstop Boards
The products manufactured by our extrusion machinery are critical components in modern waterproofing and structural sealing. Much like the versatile outputs of a plastic profile production line, these extruded boards are embedded in concrete joints. They prevent fluid migration, ensuring the longevity and safety of critical infrastructure. Our machinery produces waterstops that meet strict industry standards for underground construction, including basements and subways. They are also essential for water conservancy projects like dams and reservoirs, where continuous water pressure demands high-strength expansion joints. Additionally, highway tunnels, railway networks, and sanitary engineering facilities rely on these chemically resistant sealing solutions.
