Drop Impact Test machine is to test large and heavy package products' drop impact performance

through simulate real face ,edge and corner drop conditions. This equipment mainly used to inspect package products drop resistance capability during transportation ,load and unload works, thus help improve the package design.

Zero Hight Drop Tester enginery larger drop test is mainly used for packaging, drop test enginery zero by a can quickly moving down "E" type fork as specimens rack, according to the test subjects requirements (surface, edges, Angle, experimental) placed balance. Test, to ask board high-speed downward motion, from specimens, "E" type to pack the goods in fork dropped to negative glue, has set up a file in the high efficiency under the action of shock absorber, embedded in the floor flat, theoretically, zero drop test from zero can be highly scope drop test, drop height through the test requirements for digital set, and set according to highly automated execution experimental large packing goods fall and drop test specimen  

Testing Principle

Specimen automatically lifting to pre-setting height, then free drop and shock on the drop plate.

Technical Specification

1 This machine available for package face, corner, edge free drop testing.

2 With height digital display instrument and tracing height with encoder, so can measure the precision drop height.

3 The drop height tolerance within2% or 10mm; 

4 This machine with single wing double column structure, with electronic return, electric control dropping and electronic lifting & dropping devices, easy for operation.

5 Particular impact attenuation device largely increased the machine service life, stability and safety.

6 Drop angle impact surface and bottom plane angle less than 5o;

7 Bottom base with enough weight and thrust surface area, ensure 70kg loading from 1.5 meters height, machine with no tilt, no shake when testing, thus makes the specimen with free dropping. 

Testing Procedure
1 Fix the specimen on the drop arm, lift to the certain drop height, only±2% difference allowed between the height and setting value. Drop height refers to the distance between the lowest point when release the specimen and the shock impact plate.

2. Release the specimen according to below predetermined state:

A. Face dropping, the angle between the specimen drop face and flat plane should within 2o;

B. Edge dropping, the angle between the edge and the flat plane within 2o,the angle between upper face of specimen and shock plate within ±5oor 10% of angle(Whichever is the larger value),ensure the specimen gravity line through the dropping edge.

C. Corner dropping, the angle tolerance between the specimen upper face and shock impact plate less than or 10% of the angle(Whichever is the larger value),ensure the specimen gravity line through the dropping corner..,

D. No matter what kind shape or status of the specimen, all have to ensure the gravity line of the specimen through the dropping face, edge and corner.

3 The difference between the actual shock speed and the speed when free dropping should within ±1% .

4 After testing, check the package and inner products damage condition according to related standard or regulations. And analyze the testing result.

Notice 
1 Suggest to put this machine on first floor because of the large volume, and weight about 750kg, normal elevator can not enter in, un-easy for moving.

2 Pay attention to safety when do dropping test, do not close to the shock plate when specimen dropping, avoid injuries caused by specimen dropping or arm return, and influence of the testing results.
