Bump Test Machine

bump test machines generate standardized half-sine continuous pulses at adjustable frequencies, replicating cumulative mechanical stress from truck vibration, cargo stacking, road bumps, shipping turbulence and equipment startup-shutdown impact.

Modern manufacturing, automotive electronics, semiconductor packaging, aerospace, consumer electronics and laboratory certification institutions rely heavily on bump test machines to validate structural stability, solder joint firmness, component connection reliability and packaging protection performance before mass production and shipment.

Our series bump test machines fully comply with global mainstream testing standards including IEC 60068-2-27, JIS C 60068-2-27, MIL-STD-810G, GB/T 2423.5 and ISO 17025 laboratory calibration requirements, delivering highly repeatable, traceable test data for product R&D, quality inspection and third-party certification reports.

Our bump test machine adopts mature pneumatic or electric cam drive structures, divided into two mainstream technical routes for different test loads:

Pneumatic drive bump test machine (KRD20 series) Compressed air acts as power source to lift the test table and release it at a preset height, forming standard half-sine bump pulses. Operators adjust air pressure to control bump frequency, set drop height to regulate peak acceleration, and customize pulse duration via damping modules. The whole system runs without oil pollution, low noise, stable waveform output and easy daily maintenance, ideal for light and medium-weight samples under 100kg.

Electric cam continuous bump tester (SKM/CDS series) Precision servo motor drives customized cams to drive the worktable for periodic reciprocating bump movement, supporting adjustable bump frequency from 1 to 120 bumps per minute. Built-in multi-layer shock absorption isolation system eliminates ground vibration interference, ensuring waveform tolerance within ±15% as specified by IEC standards, perfectly matching long-duration endurance bump tests for automotive parts and medium-large equipment.

Standardized Waveform & Ultra-High Test Repeatability

All bump test machines are calibrated before delivery to output standard half-sine pulse waveforms, with peak acceleration ranging from 3g to 60g and pulse duration adjustable from 3ms to 20ms. Independent air spring isolation base and heavy-duty shock absorbers isolate external ground vibration interference, so identical test parameters produce consistent test results every time, avoiding data deviation that plagues low-cost ordinary test benches. The test data fully meets the audit requirements of third-party certification laboratories and international OEM customer quality departments.

Intelligent Touch Control System, Easy Unattended Operation

Equipped with 7-inch industrial touch HMI, all test parameters (bump frequency, acceleration value, total bump cycles, single test duration, interval standby time) can be set digitally without complex mechanical adjustment. Built-in multi-group test program storage function allows one-click recall of standard test recipes for automotive, electronic and packaging industries. The system supports real-time waveform display, automatic fault alarm (overload, air pressure shortage, abnormal stop) and automatic shutdown after test completion, enabling 24-hour unattended continuous testing to save laboratory labor costs.

1. Automotive Electronics Industry (Largest Demand Scenario)

Automotive components face continuous road bumps during vehicle operation and logistics transportation, requiring strict bump durability verification. Our bump test machines are widely used for testing car audio, rearview mirror assemblies, ECU control units, new energy battery management systems, charging modules, dashboard touch screens, wiring harness connectors and automotive sensors. Main test standards follow UN ECE automotive component reliability specifications and IEC 60068-2-27 continuous bump requirements, helping auto manufacturers eliminate hidden risks of loose wiring and component failure after long-term driving.

2. Consumer Electronics & Semiconductor Packaging

Smartphones, tablets, monitors, power banks, circuit boards, IC chips, solder bump packaging modules all suffer cumulative jolts during air and land logistics. Bump testing evaluates the bonding strength of chip solder bumps, the anti-drop performance of internal plastic brackets and the stability of screen connectors. Semiconductor packaging factories use our equipment to screen defective products in advance, reducing after-sales failure rates caused by transportation impact and improving finished product yield.

3. Aerospace, Defense & Medical Devices

Aerospace airborne equipment, military communication terminals, portable medical monitors and implant auxiliary devices must withstand bump impact during delivery and field use. Our high-precision bump test machine meets MIL-STD-810G and RTCA DO-160 aerospace environmental test standards, providing credible reliability data for product design approval and military project bidding.

4. Logistics Packaging & Household Appliance Manufacturing

Home appliances, lighting fixtures, power tools and finished product packaging boxes are tested via bump machines to verify buffer material protection performance. Manufacturers adjust packaging foam thickness, carton structure and internal fixing schemes according to test failure results, cutting packaging material costs while reducing cargo damage rates during cross-border transportation, which is especially valuable for export-oriented factories shipping goods to Europe, America and Southeast Asia.
