Manual Cold Isostatic Press 20 Ton Laboratory Powder Compaction Machine

Product Overview

This manual cold isostatic press represents a premium laboratory solution engineered specifically for high-precision powder compaction in material science research. Designed to overcome the inherent limitations of standard uniaxial pressing, this system utilizes a liquid medium to transmit equal pressure from all directions to the target powder sample. This isostatic pressure distribution eliminates internal friction and density gradients, producing compacted green bodies with excellent isotropic mechanical properties, uniform structural density, and superior post-sintering integrity.

Optimized for high-performance laboratory environments, this equipment is widely applied across a spectrum of cutting-edge industries, including advanced ceramics, solid-state battery development, powder metallurgy, pharmaceutical chemical synthesis, and electronics manufacturing. The compact footprint and highly integrated design allow this system to operate seamlessly within standard laboratory setups as well as hermetically sealed gloveboxes. This makes it an ideal choice for processing air-sensitive, hygroscopic, or hazardous materials under controlled inert gas atmospheres.

Engineering excellence and long-term operational reliability are built into every component of this hydraulic press. Featuring a patented monolithic structure that integrates the oil reservoir, hydraulic cylinder, and main body, the system eliminates traditional external connection joints to resolve the chronic oil leakage issues typical of conventional laboratory presses. With robust chrome-plated components, a high-strength transparent protective shield, and an intuitive dual-scale pressure gauge, this unit delivers repeatable, high-accuracy compaction under demanding laboratory conditions, representing a solid long-term investment for research institutes and industrial R&D teams.

Key Features

• Integrated Leak-Free Construction: The oil reservoir, main cylinder, and hydraulic pathways are integrated into a single solid-cast block, eliminating external pipe fittings and joints to prevent chronic oil leakage and ensure a clean laboratory workspace.
• Dual-Scale Precision Pressure Gauge: Displays both the applied force in Tons (0-20T) and system hydraulic pressure in MPa on a highly visible, dual-scale dial, enabling researchers to monitor and record precise compaction pressures.
• High-Performance Isostatic Chambers: Available in two optimized configurations, supporting either 0-300 MPa working pressure with a Φ30 x 150 mm chamber or 0-500 MPa working pressure with a Φ22 x 150 mm chamber to match diverse application needs.
• Glovebox-Compatible Footprint: The compact and lightweight design facilitates easy integration and operation inside standard gloveboxes, allowing safe handling of reactive or air-sensitive powders.
• Premium Imported Tool Steel Mold: The compaction chamber and mold bases are fabricated from high-grade, imported high-speed tool steel, providing extreme hardness, high wear resistance, and long service life.
• Polished Chrome Cylinder & Quality Seals: The large-diameter main cylinder features a micro-polished chrome finish paired with premium seals for smooth, low-friction operation and zero pressure decay.
• Ergonomic Aluminum Alloy Handwheel: A high-strength, precision-machined aluminum alloy handwheel allows for rapid, effortless adjustment of the upper screw rod, facilitating quick sample loading.
• Extended Piston Stroke with Solid Rebound: A generous 40mm maximum piston stroke combined with a heavy-duty return spring mechanism ensures fast, complete piston retraction without sticking or deformation.
• Comprehensive Operator Protection: Equipped with a robust, transparent acrylic (Plexiglass) protective shield that encloses the pressurized chamber, allowing complete visual inspection while maintaining strict laboratory safety standards.
• Controlled Decompression Valve: The precise manual release valve allows operator-controlled, ultra-slow pressure release, preventing cracks and structural failures in delicate compacted green bodies.

To ensure proper operational safety and control, researchers must refer to the relation between actual applied force, system hydraulic pressure, and the resultant chamber pressure within the isostatic vessel:

Note: To maximize seal longevity and preserve the mechanical integrity of the internal components, it is highly recommended to maintain the standard operational system pressure below 35 MPa.

Why Choose This Product

• Patented Monolithic Engineering: The proprietary design integrates the hydraulic oil reservoir, high-pressure passages, and compaction cylinder into a single solid piece. This eliminates external leakage pathways, ensuring a completely clean, maintenance-free, and oil-drip-free laboratory workspace.
• Isotropic Compaction Excellence: Unlike standard uniaxial lab presses that often leave internal stress concentrations and density variations in the sample, this system applies uniform, multidirectional hydrostatic pressure, guaranteeing high green-density consistency and structural reliability.
• Premium Material Selection: Built with high-strength alloys, an imported tool steel chamber, a heavily chrome-plated piston, and a robust aluminum handwheel, this system is structurally engineered to withstand thousands of high-pressure cycles without mechanical degradation.
• Highly Adaptable for Advanced Research: The compact design and optimized safety configurations make this hydraulic press universally compatible with standard laboratory benches as well as airtight inert-gas gloveboxes, making it perfect for air-sensitive solid-state battery and catalytic material trials.
• Operator-Centric Safety and Control: Designed with an ultra-clear, heavy-duty acrylic safety shield and a dual-scale pressure gauge showing force in both Tons and MPa. The manual decompression valve permits micro-controlled, slow pressure release to prevent delicate samples from bursting.
