✅ Core Applications

Designed for versatility, the J459 excels in manufacturing high-performance components, including:

• Automotive parts (engine blocks, chassis components)

• Motorcycle structural elements

• Textile machinery precision parts

• Aerospace-grade aluminum alloy castings

Key Performance Features

1. Robust Framing & Clamping System

o Four-column guided closing mechanism ensures rigidity and minimizes mold impact during fast/slow closing cycles.

o Octagonal base with four side molds for enhanced stability and uniform pressure distribution.

o Integrated safety limit device prevents accidental mold plate drop, ensuring operator safety.

2. Advanced Cooling & Molding

o Multi-circuit cooling system supports air/water cooling modes and mold temperature control (time-based or automatic).

o Rotating oil cylinder-driven pick-up tray for smooth, adjustable part retrieval.

o Hydraulic clamping mechanism enables rapid, precise mold installation and alignment.

3. Precision Temperature Control

o Radiation-heated holding furnace with PID regulation, maintaining 680–750°C ±5°C accuracy.

o Furnace trolley system for seamless movement and vertical lifting, optimized for molten metal transfer.

4. Intelligent Control Architecture

o Dual-computer monitoring system:

o Lower computer (PLC): Manages machine actions, pressure adjustments, and cooling.

o Upper computer (HMI/IPC): Handles parameter settings, real-time pressure curve monitoring, and fault alerts.

o Fail-safe operation: Lower computer continues automated processes if upper computer malfunctions.

5. Dynamic Pressure Regulation

o Closed-loop pressure control via imported pneumatic proportional valves and high-precision sensors.

o Features multi-stage linear pressurization, automatic curve tracking, and compensation for furnace leakage/liquid level fluctuations.

System Components

• Main Machine: Four-column frame, clamping mechanism, and ejector system.

• Hydraulic System: High-power drives for synchronized movements.

• Holding Furnace: Radiation-heated design with tilt/vertical movement capabilities.

• Electrical Control: PLC + HMI for full automation and data monitoring.

• Cooling System: Programmable circuits for air/water/mist cooling.

Why Choose J459?
