TMA-JB-300S Digital Display Charpy Impact Testing Machine

TMA-JB-300S Digital Display Charpy Impact Testing Machine

The TMA-JB-300S is a high-precision digital display Charpy impact testing machine designed to measure the impact resistance of metal materials under dynamic load. It provides reliable and repeatable results for evaluating material toughness and performance in critical applications.

This system calculates absorbed impact energy using the difference between the pendulum’s potential energy before impact and the remaining energy after fracture. With a maximum impact capacity of 300 joules and an additional 150 joule pendulum included, the TMA-JB-300S is well suited for a wide range of metallic material testing applications.

The machine features semi-automatic operation for ease of use, high testing efficiency and consistent performance. It is widely used in quality inspection, metallurgy, machinery manufacturing, pressure vessels, automotive production, universities and research laboratories.

Key Features and Performance

The TMA-JB-300S is designed for accurate measurement of material resistance to impact under dynamic loading conditions. It uses digital dial display technology to precisely indicate absorbed energy after specimen fracture.

Semi-automatic control allows simple operation while maintaining high throughput for continuous testing. After each test, the pendulum automatically returns using residual energy, making it highly efficient for repeated testing programs.

The system supports standard Charpy specimen sizes of 10 × 10 mm and delivers consistent impact speed and repeatable energy readings. A robust frame construction ensures long-term stability and measurement reliability in demanding laboratory and industrial environments.

A semi-enclosed safety protection net is supplied as standard to ensure operator safety during testing.

International Testing Standards Compliance

The TMA-JB-300S is designed to comply with a wide range of international testing standards including:

• ASTM E23
• ISO 148 Parts 1, 2 and 3
• ISO R83
• GB/T 229
• GB/T 3808
• JJG 145

This ensures full compliance for certified Charpy impact testing across global industries.

Technical Overview

The TMA-JB-300S delivers a maximum impact energy of 300 joules and is also supplied with a 150 joule pendulum for lower energy testing. It operates with a pendulum preparing angle of 150 degrees and an impact speed of 5.2 metres per second.

Specimen support span is 40 mm, with precision-machined support jaws and impact blade to ensure consistent fracture behaviour. The system supports standard Charpy specimen dimensions of 10 × 10 × 55 mm, with optional thickness configurations available on request.

The unit operates on a three-phase 415V power supply and features a solid machine weight of approximately 420 kg for excellent vibration control and test stability.
