Machine Information

LJC03-450T Extrusion Press Machine

1.Application and operating principle

Horizontal extruder is also called horizontal extrusion press machine. This is a specialized equipment which extrudes aluminum and other non-ferrous slugs into germ tubes or cylindrical objects and other shapes.

The LJC03-450T extrusion press machine developed by our company, is a high speed aluminum extrusion device of new generation. This equipment comes with vibratory bowl which automatically arrange the aluminum slugs in order and send them to the laying-off rail. The machine manipulator sends the slugs precisely into the punch cavity. Under the action of the crank-shaft connecting rod, swing rod and sliding block, the aluminum slugs are extruded in desired shape and size.

The clearance between lip of punch and die controls pipe thickness. Through the annular slot between the die bottom and tip of punch, the slugs are pressed and turned into germ tubes, the extruded part is automatically unloaded to the out feed conveyor which transfers the product to next operation stage.

2.Main features

A.The complete machine is controlled with SIEMENS PLC, which ensures smooth control and synchronize the operation with safety. Fail safe lubrication, automatic detection of tube sticking to die and punch, are added features.

B.The machine adopts whole cast steel structure (one-time casting) and has excellent rigidity and impact resistance. The body of the lathe is processed by large processing center. Mandrel and some other units are processed by CNC equipment, reaching high precision degree.

C.The seat of the tip of punch adopts the form of double inclined plane with accurate location. Punch base and connecting rod employ adjustable structure, which can eliminate the gap caused by the wear and tear of long term operation and ensure long-term high precision of equipment.

D.The key parts use high quality bronze alloy to reduce friction coefficient, increase wear resistance and prolong working life.

E.The machine employs whole closed lathe body design, which can avoid the dropping of lubricant onto the floor.

F.Easy operation and maintenance. The machine meets the concept of energy conservation and environmental protection.

1. What is the LJC03-450T Extrusion Press Machine used for?

The LJC03-450T is a high-speed horizontal extrusion press designed to extrude aluminum and other non-ferrous slugs into tubes (germ tubes), cylindrical objects and other shapes for downstream processing in tube production lines.

2. What are the main technical specifications of the LJC03-450T?

Nominal pressure: 800 kN; tube diameter range: φ35 mm–φ66 mm; tube length: ≤250 mm; production speed: 90–120 tubes/min; motor power: 37 kW.

3. What is the operating principle of this horizontal extrusion press?

Slugs are fed from a vibratory bowl and placed into a laying-off rail. A manipulator inserts each slug into the punch cavity. A crankshaft–connecting rod mechanism with swing rod and sliding block extrudes the slug through the die/punch annular gap to form the tube, which is then unloaded to the outfeed conveyor.

4. What control and automation components are used on the machine?

The machine is controlled by a SIEMENS PLC with a Pro-face touch screen for operator interface. Key electrical components are SCHNEIDER or OMRON. Photoelectric and proximity sensors include TURCK and BANNER; pneumatic elements are FESTO.

5. How does the machine ensure extrusion precision and long-term accuracy?

The machine uses an entire cast steel one-time cast structure machined on large centers, CNC-processed mandrel and critical components, a double-inclined-plane punch tip seat for precise locating, and adjustable punch base/connecting rod structures to compensate for wear.

6. What features reduce wear and friction on key components?

Key wear parts are made from high-quality bronze alloy to reduce friction, increase wear resistance and prolong service life. In addition, the machine employs fail-safe lubrication systems and a closed lathe body to protect components.

7. What safety and fault-detection features are included?

SIEMENS PLC control synchronizes operations and safety interlocks. The machine has automatic detection for tube sticking to the die or punch, fail-safe lubrication alarms, and a closed-body design to prevent oil drips and reduce operator exposure.

8. Can the LJC03-450T be integrated into a fully automatic aluminum tube production line?

Yes. The machine is designed to operate standalone or as part of a modular automatic line that includes trimming, annealing, lacquering, printing, curing, capping, and packaging machines produced by the same supplier.

9. Which downstream and upstream machines is this press commonly paired with?

Typical line partners include LWG01 trimming, THG01 annealing oven, PTG01 internal lacquering, GHG01 lacquering curing oven, CCG01 accumulator, DYG01 base-coating, YSG01/YSG02 printing, HXG01 drying oven, NMG01 capping, WTG01 latexing and BZG01 packaging machines.

10. What materials can be processed on the LJC03-450T?

The machine is intended for aluminum slugs and other non-ferrous slug materials suitable for extrusion into tubes and related profiles. Material compatibility should be confirmed with the supplier for specific alloys and temper conditions.

11. What maintenance is recommended to keep production stable?

Regularly check and maintain the fail-safe lubrication system; inspect punch/die and bronze bearing surfaces for wear; maintain vibratory bowl and feed rails for consistent feeding; verify sensor alignment; and follow scheduled checks for drive, crankshaft and connecting rod clearances.

12. What common troubleshooting steps should be taken for feeding or sticking problems?

Check vibratory bowl and feed rail settings, ensure manipulator timing and sensor signals are correct, inspect punch and die clearances and surface condition, confirm lubrication is functioning, and review PLC alarms to identify stuck-tube or misfeed causes.

13. Is the machine energy-efficient and environmentally friendly?

The machine is designed with energy conservation and environmental protection in mind (closed-body to prevent oil spills and optimized drive systems). Exact energy consumption will depend on operating parameters; the motor is rated at 37 kW.

14. Are customization, installation and commissioning services available?

The LJC03-450T is supplied as part of configurable production lines and can be adapted to customer needs. Installation and commissioning are typically provided by the supplier or their agents—contact your sales representative for service scope, lead times and customization options.

15. How do I order spare parts or get technical support?

For genuine spare parts, recommended consumables and technical support (including PLC programs and electrical diagrams), contact the machine supplier or authorized distributor. Provide machine model, serial number and part details to ensure correct parts and support.
