Drop-Weight Impact
Product/Package Durability Testing

The QM720D drop-weight impact tester releases a weight from a fixed height to assess damage, internal condition and durability. With a pneumatic automatic gripper and automatic transfer, distance resolution ±0.01 mm, max stroke 1100 mm, test-height memory and auto home reset.

From finished packaging to components - products can suffer falling-weight impacts in handling; drop-weight testing simulates this to rate impact damage resistance. Safe pneumatic release with precise, reproducible height makes it key equipment for package/product reliability.

Designed for product impact durability - weight release plus precise height for package reliability testing.

FAQ

Answers to common questions about QM720D purchasing, delivery and service

What is the QM720D mainly used for? +

The QM720D is a drop impact tester that free-drops specimens/products from a fixed height to rate housing cracks, internal damage, loose joints and durability - common equipment for drop reliability of phones, laptops, appliances and auto parts.

What are the key specifications? +

Refer to the specifications: stroke Max.1100mm, speed range 0~750mm/min, distance resolution ±0.01mm, pneumatic gripper distance adjustable; dimensions 900(W)×550(D)×1975(H) mm.

How does the gripping system protect specimens? +

The Air Gripper adapts pneumatic pressure to grip distance, even surface pressure, ensuring a consistent drop posture without damaging the housing; automatic grip or electronic interchangeable adapters are optional.

How is height accuracy ensured? +

distance resolution ±0.01mm, with test-height memory and auto home reset/calibration, so drop-height error across a batch is minimal.

Which test standards are supported? +

Corresponding to JIS C 60068-2-31 (free drop of portable equipment), ASTM D5276, GB/T 2423.8 (free drop of electrical/electronic products) and other product drop methods.

Which options are supported? +

Electronic interchangeable adapters and grips for different specimen shapes are optional; special specimen sizes/weights are confirmed per order.

What is the lead time for standard models? +

Standard-model lead time is 3-8 weeks; special fixtures and adapters are delivered per the contracted lead time once confirmed.

How are certification and after-sales service secured? +

The unit carries CE / ISO 9001 certifications and is calibrated for height and grip 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.
