The rubber pre‑forming extruder is a plunger‑type machine, primarily composed of an extrusion unit, a hydraulic system, a vacuum system, a water‑circulation system, an electric heating system, a pneumatic system, a cutting system, and an electrical control system. 1. Extrusion unit: Consists of a hydraulic cylinder, a barrel, and a die head. 2. Hydraulic system: Employs a high‑pressure gear pump and flow valves; the hydraulic oil in the cylinder is regulated by the flow valve, while a differential pressure valve maintains a constant pressure difference before and after throttling, enabling precise control of the weight of the extruded rubber billet. 3. Pneumatic system: Used to control the opening and closing actions of the die head. 4. Vacuum system: Prior to extruding and cutting the rubber material, a vacuum is first applied to remove air from the barrel.

1. Extrusion unit: Composed of a hydraulic cylinder, a barrel, and a die head, among other components.
2. Hydraulic System: A high-pressure gear pump and a flow control valve are employed. The hydraulic oil supplied to the hydraulic cylinder is regulated by the flow control valve, while the differential pressure across the throttle remains constant, enabling precise control of the weight of the extruded rubber billet.
3. Pneumatic device: used to control the opening and closing of the machine head;
4. Vacuum System: Prior to extrusion and cutting of the rubber compound, a vacuum is applied to remove air from the barrel and die head as well as entrapped gases within the compound, thereby enhancing the quality of the subsequent vulcanized products.
5. Heating System: Utilizes a water‑circulation heating method, with temperature controlled and displayed by a digital thermostat. This ensures stable temperatures in both the die head and the barrel.
6. Cutting Unit: Composed of a frame, an electric motor, and a reduction gear system. The cutting motor is equipped with a variable-frequency drive for speed control, and a conveyor mechanism is mounted at the lower portion of the frame.
7. Equipped with a high-definition LCD touch screen and a PLC to achieve fully automatic operation;
8. Utilizes an electronic weighing feedback system for communication control, automatically adjusting the blade speed to ensure that the cut rubber blanks achieve the desired weight.
Applications: The rubber pre‑forming machine is a high‑precision, high‑efficiency device for producing rubber blanks. It can manufacture blanks of various hardness levels and shapes, with excellent dimensional accuracy and no air bubbles, making it ideal for producing rubber components such as oil seals, O‑rings, tennis balls, golf balls, valve stems, shoe soles, automotive parts, agricultural granules, and more.
