Product Description

Scope of Application

- Extrusion of copper and phosphor copper alloy wires in various specifications

- Extrusion of silver and silver alloy wires in various specifications

- Extrusion of zinc and other non-ferrous metal wires

Core Structural Design

The machine adopts a front-mounted extrusion die design, where the die is installed between the cylinder front seat and the piston rod. This innovative design enables full extrusion of materials inside the die in a single cycle, minimizing residual tailings and ensuring material utilization efficiency. During the extrusion process, the die remains stationary with secure fixation, allowing continuous extrusion of successive billets to produce seamless wires with robust joints at connection points.

Featuring an automatic opening-closing die structure, mold replacement is streamlined: simply press the mold-opening button, and the two front-mounted cylinders will separate the die for easy disassembly and installation. The machine is compatible with billets of up to Φ60 mm in diameter and 150 mm in length, with adjustable billet dimensions to accommodate the characteristics of different processed materials.

Composed of four core systems—mechanical system, hydraulic system, heating system, and CNC system, this advanced large-tonnage four-column horizontal extruder. It offers prominent advantages including time-saving operation, labor reduction, low energy consumption, and stable performance, making it ideal for high-efficiency alloy wire production.

The main cylinder adopts a piston-type composite master-slave cylinder structure, enabling rapid forward movement during the idle stroke to reduce non-productive time and boost overall production efficiency. Integrated with world-leading hydraulic speed control technology, the hydraulic system ensures safe and reliable operation even under heavy loads.

Product Features

1. High-Precision Main Cylinder: Manufactured with German technology, the piston-type main cylinder has a rated working pressure of 24 MPa (240 kg/cm²). The hydraulic system provides powerful and stable constant-speed performance, ensuring uniform metal flow, stable extrusion, and firm bonding of wire joints.

2. Built-in Slave Cylinder: With a rated working pressure of 24 MPa, it is equipped with a rapid oil charging function that shortens idle time, accelerates pressure build-up, and further improves production efficiency.

3. Four-Guide-Rod Structure: Enhances the overall rigidity of the machine, ensures balanced distribution of extrusion force, and guarantees consistent product quality batch after batch.

4. Front-Mounted Die & Continuous Extrusion: The front-mounted die design enables continuous extrusion without the need for extrusion discs used in conventional machines, simplifying the production process and reducing intermediate operational steps.

5. Automatic Opening-Closing Die with Slide Plate: The front-mounted die integrates an opening-closing slide plate, with the extrusion die mounted on the plate. Two side-mounted cylinders support the slide plate to prevent backward displacement during extrusion. For mold replacement, the cylinders drive the slide plate to slide open, allowing easy access to the mold.

6. Double-Layer Die with Electromagnetic Induction Heating: The die adopts a double-layer structure made of high-temperature-resistant special materials processed by specialized heat treatment, exhibiting excellent high-pressure resistance, high-temperature resistance, and hardness retention to avoid hardness degradation under high operating temperatures. The electromagnetic induction heating technology heats the die faster and more efficiently than traditional resistance heating coils, supporting multiple temperature settings to meet the diverse needs of different alloy extrusion processes.

7. Automatic Mold Opening-Closing & Ejection System: Two mold opening-closing cylinders are installed on both sides of the machine. After the cylinders push the movable die plate open, a mold ejection cylinder on the front seat drives the mold base plate to move. The base plate is designed with two holes—one for wire extrusion and the other for mold ejection. When the base plate moves to the ejection position and the movable die plate closes, the ejection rod pushes the mold out of the base plate, realizing quick and convenient mold changeover.

8. High-Performance Mold & Extrusion Rod: Both the extrusion mold and rod are forged from high-temperature-resistant special materials, followed by precision machining and specialized heat treatment, boasting superior high-pressure resistance, high-temperature resistance, and wear resistance. Since the machine does not require extrusion pads, the mold and rod are engineered to higher precision and performance standards to ensure stable and continuous extrusion.

9. Rigid Cast Steel Frame: The front and rear seats of the machine are made of cast steel, providing exceptional structural strength and rigidity. This design maintains the coaxiality and perpendicularity accuracy between the ejection rod and die even under high extrusion pressure.

10. Advanced Dual-Circuit Hydraulic System: The hydraulic system consists of two independent circuits—high-pressure and low-pressure. The high-pressure circuit powers the main cylinder and rapid-feeding cylinder, while the low-pressure circuit controls the mold opening-closing and ejection mechanisms. The high-pressure circuit is driven by two oil pump motors: the main pump motor for extrusion operation, and the auxiliary motor for rapid oil charging and pressure build-up. After rapid oil charging, the auxiliary motor switches to circulating hydraulic oil through the cooler to prevent excessive oil temperature rise.
