Overview
Cometech QC-113A Pneumatic Type Drop Tester is used to evaluate the impact resistance of packaging and electronic products during transportation by simulating free‑fall drop conditions.
It uses a single‑wing structure designed to occupy a small space while supporting common drop test scenarios for cartons and electronic products.
The system uses pneumatic power for fast, stable release and includes height adjustment hardware for accurate drop-height setup.

Base plate options
- Optional base plate sizes listed: 85×150 cm, 120×150 cm, 120×180 cm, 150×180 cm, 180×180 cm, 240×150 cm.
- Cometech notes that drop testing requires releasing samples onto a flat and rigid surface (base plates), and custom base plates can be designed for unique sample dimensions.
Key features
- High accuracy ball screw to reduce noise and improve product life cycle; brake helps control and adjust the height accurately.
- U‑joint fixing fixture with adjustable arm mechanism to secure different box sizes; allows fixing at corners and edges to enable corner/edge drops.
- Casting body structure enhances rigidity, stability, and shock-absorbing capability.
- Pneumatic-powered release helps ensure fast and stable release and reduces reversal/deviation during free fall.
- Reinforced base plate; standard base plate uses a welded steel frame for durability and mobility, and can be tailored to object dimensions.
Drop orientations (“one corner, three sides, six faces”)
- The standard drop-test concept covers drops on flat surface (face), side/edge, and corner according to specified parameters, and packaging/product damage or functional issues indicate failure.
