In modern chemical production lines, mixing and discharging are two closely connected key links. For many high-viscosity materials, the discharge process after mixing is often more challenging than the mixing itself. The traditional gravity dumping or simple pumping methods often show inadequate force when facing paste-like, high viscosity adhesives or resins, resulting in low efficiency and easy material residue and waste. FYL Hydraulic discharging machine. It seamlessly connects with equipment such as dual planetary power mixers and multifunctional mixers, providing a stable and efficient solution for the packaging and circulation of high viscosity materials.

      FYL Hydraulic discharging machine， also known as a hydraulic extruder, has a core design concept of "pressure-driven, stable extrusion". The device drives the pressure plate through a hydraulic system to apply continuous and uniform pressure to the material in the material bucket. This pressure can overcome the huge internal friction resistance of high viscosity materials and smoothly squeeze them out from the discharge port or pressure plate pipeline at the bottom of the material barrel. Compared to other discharge methods, the advantage of hydraulic drive lies in its controllable and continuous power. It can achieve precise material transportation, whether it is docking with filling stations or downstream process pipelines, and can maintain a stable flow.

      The design of this device fully considers the operational convenience and cleaning needs in actual production. Its structure is compact and can be used in conjunction with various specifications of material buckets. During the discharge process, the pressure plate is pressed tightly against the surface of the material, minimizing residue on the inner wall of the material barrel. This characteristic is particularly important for expensive chemical raw materials, as it not only reduces material loss but also reduces the frequency and difficulty of cleaning the material bucket. For products such as ink and resin that require extremely high batch purity, the low-residue design effectively avoids cross-contamination between different batches and ensures the stability of product quality.

      The application value of the FYL Hydraulic Discharging Machine is fully demonstrated in the processing of special materials such as hot melt adhesive. Hot melt adhesive is a thermoplastic polymer with 100% solid content, and common substrates include EVA, polyolefin, and polyamide. Unlike solvent-based adhesives, hot melt adhesives are solid at room temperature and must be heated to a molten state before they can flow and be applied. This physical property imposes special requirements on the equipment during the discharge process after production.

       Hot melt adhesive has the characteristics of fast curing speed and solvent-free emission, which makes it significantly advantageous in terms of environmental protection and safety. It is widely used in packaging carton sealing, book binding, woodworking furniture edge sealing, textile and garment industries, and other fields.

       However, precisely due to its high viscosity and thermoplastic characteristics, the material is prone to cooling, solidification, or wall hanging at the outlet during the transfer from the mixing kettle to the packaging barrel. The FYL Hydraulic Discharging Machine ensures rapid and continuous discharge of molten hot melt adhesive through stable hydraulic thrust, avoiding local overheating or degradation caused by poor flow.

      In addition, the reworkability of hot melt adhesive (i.e., the ability to melt again after heating) is an advantage, but it also requires production equipment to have good temperature maintenance and flow control capabilities. When used in conjunction with heating and insulation material buckets, FYL equipment can ensure that the material is always in the optimal fluid state during the extrusion process. Whether used for high viscosity woodworking edge banding adhesive or packaging adhesive with slightly better fluidity, hydraulic discharge machines can provide matching extrusion pressure to ensure the accuracy of filling measurement. This precise conveying capability directly ensures the uniformity of coating for downstream users when using hot melt adhesive, thereby ensuring the firmness of carton sealing or the smoothness of furniture edge sealing.

      Therefore, the FYL Hydraulic Discharging Machine has successfully solved the problem of difficult discharge of high viscosity materials with its efficient hydraulic drive system and low-residue pressure plate design. It not only enhances the automation level of the production line, but also provides a solid process guarantee for the stable quality of high-end adhesives such as hot melt adhesives.
