Movable Water Trough

Movable water trough is often used in water-cooling strand extrusion production line, and its main functions are to cool and comb the material strips. It can be widely applied in various fields such as plastic processing, rubber products, cable production, composite materials, and food processing.

The water trough is roughly composed of two parts: water tank (upper) and base (lower). The water tank is usually made of stainless steel and is equipped with conveyor rollers (with comb grooves to prevent the material strips from tangling) on the top. The cooling water in the tank is usually tap water. The upper layer of the base is equipped with handwheels and lead rails. The water tank above can be controlled to move forward and backward by turning the handwheel while keeping the base stationary, which is convenient for cleaning the extruder die head. The lower layer of the base is equipped with castors and foot supports for easy movement and support.

Functions and Advantages：

1. Rapid cooling and shaping: enable the high-temperature materials extruded by the extruder to cool down rapidly, facilitating the next step of pelletizing.
2. Precise temperature control:
   • By adjusting the water temperature (such as by equiping heating or cooling devices), the cooling rate can be precisely controlled to meet the process requirements of different materials (such as PVC, PE, PP, etc.);
   • Some water tanks support segmented temperature control to meet the cooling requirements of different parts of the products.
3. Movement flexibility: the position of the water tank can be quickly adjusted through devices such as lead rails and castors, facilitating the connection with extruders or production lines of different specifications and enhancing production flexibility.
4. Cleaning and Maintenance: some designs feature detachable water tank walls or automatic drainage functions, which facilitate the cleaning of residual material debris, oil stains or chemical impurities during the cooling process, maintaining clean water quality and extending the service life of the equipment.

Main application for rubber and plastic:

1. Fiber reinforcement: PP, PA, PBT, PET and other resins are filled with glass fibers or carbon fibers, engineering plastics such as ABS+PC, ABS+PA, etc
2. Polymer blending: PP/PE/PA+GF, TPU+EVA, etc.
3. Filling modification: resins such as PE, PP, EVA and so on are filled with calcium powder, carbon powder, talcum powder, titanium dioxide, etc., in low filling rate;
4. Cable materials: PVC, XLPE, PE low smoke zero halogen, EVA shielded, etc;
5. Various masterbatches: color masterbatch, flame-retardant masterbatch, degradable masterbatch (better not containing hydrolyzed materials such as starch, etc)…
