The GBPI GB-LQ is a specialized, high-rigidity falling ball impact tester engineered to evaluate the dynamic mechanical shock resistance, shatter resistance, and structural fracture behavior of rigid plastics, electrical appliance housings, consumer electronics, display panels, composite sheets, and pharmaceutical packaging components. Manufactured in conformity with recognized packaging and structural integrity criteria including YBB 0021-2005 and GB/T 14485, this instrument verifies whether finished products and plastic assemblies can withstand unexpected drop shocks and mechanical blows encountered during transit and operational usage.
Rigid polymer enclosures, battery covers, cosmetic compacts, and medicinal blister pack lids frequently suffer mechanical cracking, internal latch fractures, or splintering when dropped onto hard surfaces or struck by falling objects. Operating as a standardized falling ball impact tester, the GB-LQ suspends a precision-machined steel ball of calibrated mass and diameter via an electromagnetic chuck at a precisely set height. Upon electrical trigger activation, the electromagnetic field collapses instantly, releasing the steel ball in a true vertical free fall onto the targeted impact center of the test specimen held securely in the clamping stage below.
Stepless Height Adjustment & Calibrated Ball Options
The instrument features a smooth vertical guidance column with engraved metric graduations allowing continuous drop height positioning between 20 mm and 2000 mm. Operators can configure impact energy precisely by pairing adjusted fall elevations with interchangeable chrome alloy steel balls, standardizing testing across delicate electronic components and heavy industrial mold components alike.
Electromagnetic Release & Secure Specimen Clamping
The zero-friction electromagnetic release eliminates mechanical latch vibration and rotational spin, guaranteeing an authentic normal angle of incidence. The adjustable specimen clamping bed firmly locks planar coupons and complex molded housings up to 150 × 150 mm, preventing specimen bounce and ensuring repeatable impact verification.
Widely adopted by consumer electronics brands, injection molders, medical device manufacturers, and quality assurance laboratories, the GB-LQ provides reliable physical shock screening to safeguard product durability and end-user safety.

Key Performance Features of the GBPI GB-LQ
- Broad 2-Meter Height Adjustment: Precision height positioning slider with fine manual locking thumb screw spans from 20 mm up to 2000 mm to simulate varying real-world drop intensities.
- Zero-Distortion Electromagnetic Release: Electrically energized magnet secures steel balls securely and de-energizes instantaneously without mechanical deflection or parasitic trajectory spin.
- Interchangeable Calibrated Chrome Balls: Comes equipped with standard precision ground hardened steel spheres manufactured to exacting diameter and weight tolerances.
- Versatile 3D Specimen Stage: Flexible clamping vice locks flat panels, contoured injection-molded casings, display lenses, and cosmetic assemblies rigidly under the target point.
- Heavy Anti-Vibration Base: Solid steel base plate dampens rebound shock waves, ensuring specimen stress is entirely generated by the initial ball impact strike.
- Integrated Safety Guide Sleeve: Transparent protective containment ring catches bouncing steel spheres after impact, preventing laboratory hazards.
