Film impact tester

A Film Impact Tester is a device designed to measure how well a film or thin material can withstand sudden impact or shock without breaking, cracking, or puncturing. It is commonly used in laboratories and quality control environments.

Product Introduction

The film impact testing machine, through the hemispherical punch at a certain speed, impacts and passes through the film sample, measures the energy consumed by the punch, and evaluates the anti-pendulum impact energy of the film sample.

The sample to be measured is placed in the middle of two splints to clamp, and the pendulum is adjusted by counterweight to form enough mechanical energy to impact the surface of the sample to be measured during the impact process to break down or not break down the sample to be measured. The energy borne by the sample to be measured is the loss part of the total mechanical energy formed by the pendulum during the impact process, and is read out on the dial through the pointer.

Accessories

(1)Dart (Impact Head)

A hemispherical impact head used to strike the film specimen.

(2)Weight Set

Used to adjust the total impact mass to meet different test standards.

(3)Specimen Clamping Device

Holds the film securely to prevent movement during testing.

(4)Guide Tube (Drop Tube)

Ensures the dart falls vertically and impacts the correct position.

(5)Release Mechanism

Controls the accurate release of the dart from a specified height.

Test Procedure

(1) Preparation

Ensure the equipment is clean and in proper working condition.

Select the appropriate test method and weight according to standards.

(2) Specimen Preparation

Cut the film sample to the required size.

Make sure the specimen is smooth, clean, and free from defects.

(3) Mount the Specimen

Place the sample between the clamping rings.

Tighten securely to avoid slipping during testing.

(4) Set Parameters

Choose the correct dart weight.

Set the drop height or testing method.

(5) Conduct the Test

Raise the dart to the specified height.

Release the dart to impact the specimen.

Observe whether the film fails (breaks) or remains intact.

(6) Record Results

Record pass/fail results.

Repeat the test as required and calculate average values or failure probability.

(7)After Testing

Remove the tested specimen.

Clean the test area.

Turn off the equipment.
