Falling-Dart Impact
Plastic-Film Impact-Toughness Testing

The QM720FD uses the free-falling dart method (A & B) to measure plastic-film impact strength and toughness. Pneumatic clamping and electromagnetic release keep conditions consistent; Method A head Ø38.1 mm with 5/15/30/60 g weights; Method B head Ø50.8 mm optional.

From packaging film to battery separator - whether film cracks on impact directly affects packaging protection and material safety. The dart method is the international standard for film impact; the up-and-up method finds the 50% break height, giving stable, reproducible data.

Designed for film impact rating - dart method plus pneumatic clamp, ASTM D1709 film standard compliant.

The QM720FD Falling-Dart Impact Tester per ASTM D1709 and ISO 7765 measures plastic-film impact toughness and break energy by the free-falling dart method (A & B); dedicated QC equipment for packaging film, Li-battery separator and agricultural film.

What are the key specifications? +

Refer to the specifications: test method Method A / Method B (Option), range Method A 50~2000 g / B 300~2000 g, max stroke 1450 mm, dimensions 900(W)×550(D)×2050(H) mm.

What is the difference between Method A and B? +

Method A is the light-dart method; head Ø38.1mm, with 5/15/30/60 g weights, for thinner films; Method B is the heavy-dart method (option), head Ø50.8mm, with 15/45/90 g weights, for thicker or tougher films.

How is the specimen clamped? +

Uses Pneumatic specimen clamp (pneumatic clamp); compressed air rings the film edge flat and wrinkle-free; the electromagnetic dart holder energizes to hold and de-energizes for free release, with no initial-velocity interference.

Which test standards are supported? +

Strictly compliant with ASTM D1709 (free-falling dart impact test method for plastic film) and ISO 7765-1 (determination of free-falling dart impact resistance of plastic film and sheeting).

Which film materials suit it? +

Impact-toughness rating of flexible thin materials such as PE packaging film, stretch wrap, Li-battery separator, agricultural film and composite flexible packaging.

What is the lead time for standard models? +

Standard-model lead time is 3-8 weeks; Method B head and weight set are optional, delivered per the contracted lead time.

How are certification and after-sales service secured? +

The unit carries CE / ISO 9001 certifications and is calibrated for dart height and clamp force before shipment; after-sales includes 2 hours emergency response, on-site commissioning by certified engineers, a full-machine 1-Year Warranty warranty and lifetime software upgrades.
