1、 Overview of this device:

The DuPont impact testing machine is used to test the impact resistance of plastic specimens, PVC specimens, and coating specimens. Place the test piece under the impact head of the machine, drop it with a heavy hammer at a certain height, and inspect for damage, deformation, or peeling.

The structure of this machine is applicable to multiple national standards, and only the corresponding impact head needs to be selected according to different testing requirements.

Principle: This instrument adjusts a steel ball with a specified weight to a certain height, allowing it to fall freely and strike the sample, depending on the degree of damage.

2、 Compliant with standards:

JIS K5600-1999, ASTM, EN, GB, ISO, UL and other related standards.

3、 Main technical parameters:

1. Sample: Plastic test piece

2. Falling height: 50-1000mm, spaced 50mm apart

3. Ball drop control method: manual setting

4. Hammer weight: 500G, 1000G, each equipped with 1 PCS

5. Cone radius: 6.4mm (1/4in) 4.8 (3/16in) 12.7 (1/2in)

3.2 (1/8in) 7.9mm (5/16in) 1.9mm (1/16in)

6. Test piece seat radius: flat 8.1mm

7. External dimensions (D * W * H):

8.450 * 580 * 1280mm

9. Weight: 60kg

4、 Test steps:

1. Lift the support plate along the rotation axis to the required height for testing, tighten the fixing screws to secure it to the rotation axis.

2. Turn the wrench, place the weight on the pallet, and add or subtract the weight of the weight according to the testing requirements (the base weight is 500g).

3. Place the punch inside the guide sleeve.

4. Place the impact seat (inside the fixing ring of the fixing plate).

5. According to the testing requirements, select the test piece and place it on the impact seat to maintain free contact between the punch and the test piece.

6. Pull the wrench outward, and the support plate will detach from the weight. The weight will fall freely and impact the punch. The test piece will be subjected to a predetermined impact force, causing deformation.

7. Take out the test piece and measure the height of the lowest point of the test piece with a ruler, which is the gap between the impact deformation points of the punch

5、 Notes:

Try not to use this DuPont impact testing machine in the following situations:

1. In situations of vibration and swaying.

2. A place directly exposed to sunlight.

3. High temperature, dusty, and humid places.

4. The AC power supply to this machine should be well grounded to ensure safe use.

5. It is strictly prohibited to use strong solvents (such as benzene, nitro oil) to clean the machine hub.

6. Water and debris must not be injected into the machine to prevent damage to electrical components and electric shock.

7. The disassembly and debugging of the instrument display can only be carried out by units approved by the National Department of Metrology and our company, and others are not allowed to disassemble and repair it without authorization.

6、 Maintenance methods:

1. Cleaning: Keep the machine clean at all times. Before and after each use, wipe the machine with a cotton cloth to keep it clean.

2. Rust prevention: Spray rust prevention oil on the metal parts of the machine surface once a week (spray for 2 hours and wipe clean).

3. Lubricating oil: Regularly lubricate the transmission components (such as screws) of the machine every month (using ordinary lubricating oil is sufficient).

4. Maintenance: Regularly check whether the control panel buttons are working properly.
