Marshal Sample Extruder

About Marshal Sample Extruder

The Marshal Sample Extruder is a precision laboratory equipment used for efficient removal of compacted asphalt, CBR, and Proctor specimens from moulds. It is widely used in civil engineering laboratories, construction quality control labs, and research institutions.

This equipment operates using a manual hydraulic jack mechanism, enabling smooth and effortless extrusion of samples without damaging their structure. It is designed to handle standard mould sizes and ensures accurate and quick sample preparation for further testing.

Key Features

• Heavy-duty steel frame construction for durability
• Equipped with manual hydraulic jack for easy operation
• Suitable for 4" (100 mm) and 6" (150 mm) moulds
• High load capacity (approx. 30 kN or above)
• Quick and safe extraction of specimens
• Corrosion-resistant finish

Technical Specifications

• Capacity: 30 kN (approx.)
• Operation: Manual (Hydraulic Jack)
• Mould Compatibility: Marshall, CBR, and Proctor moulds
• Diameter Range: 100 mm & 150 mm
• Frame Type: Vertical extrusion frame
• Material: Mild Steel / Heavy-duty steel

Applications

• Bitumen and asphalt testing laboratories
• Soil testing labs (CBR & Proctor tests)
• Civil engineering colleges and research institutes
• Construction and road quality control testing

Working Principle

The apparatus uses a hydraulic jack to apply vertical force, pushing the compacted specimen out of the mould. This ensures smooth extraction without altering the physical properties of the sample, which is critical for accurate testing
