Simple Beam pendulum Impact Tester

metal Material Impact Resistance Test Testing Machine Specification:

I. Equipment Overview

1. Core functions

Testing Principle: Measurement of the energy absorbed by fracture of a material to assess its impact toughness by impacting a horizontal simply supported beam specimen with a pendulum falling freely (Charpy test).

Applicable standards:

GB/T 1043 (Impact properties of plastic simply supported beams)

GB/T 229 (Charpy notched impact of metallic materials)

ASTM D6110 (plastics), ISO 179-1 (international standard), etc.

2. Equipment features

Simple structure: modular design, small footprint (about 1m2), no need for complex installation.

Convenient operation: manual or semi-automatic operation, suitable for basic testing needs.

Low cost: price usually ranges from 30,000 to 100,000 RMB (for domestic equipment), with low maintenance costs.

2. Examples of technical parameters

Parameter

Description

Pendulum energy

15 J, 25 J, 50 J (plastic), or 150 J, 300 J (metal).

Specimen size

Plastic: 80×10×4 mm (notched specimen); Metal: 10×10×55 mm (V-notch).

Testing efficiency

Manual operation, approx. 5-10 min/test.

Power Requirement

220V single-phase power supply, power ≤ 500W.

III. Applicable Scenarios

1. 

Educational institutions: experimental teaching of material mechanics, demonstrating the principle of impact fracture.

2. 

Small and medium-sized enterprises: quality control of plastic products (such as toys, daily necessities) or metal small parts.

3. 

R&D initial screening: preliminary toughness assessment of new materials (e.g. modified plastics, low alloy steel).

Fourth, the test process (plastic simple beam impact as an example)

1. 

Specimen preparation:

Injection molding or cutting standard specimen (80 × 10 × 4 mm), machining V-notch (depth 2 mm).

2. 

Equipment calibration:

Empty pendulum test, calibrate pointer zero (energy loss ≤ 2%).

3. 

Specimen mounting:

Place the specimen horizontally in the fixture with the notch back to the direction of pendulum impact.

4. 

Test execution:

Manually lift the pendulum to a predetermined angle and release the pendulum to impact the specimen.

5. 

Result reading:

The pointer scale displays the fracture energy and calculates the impact strength (in kJ/m2).

V. Suggestions for selection

1. Key parameters

Energy range: select according to the type of material (0.5-50 J for plastic, 50-300 J for metal).

Display: Digital display (high precision) > Pointer (low cost).

Expandability: whether to reserve upgrade interface (such as high and low temperature environment box).
