Corrugated boxed compression strength testing machine

1. Introduction and test principle of compression strength measuring

The compression testing machine is to measure compression strength of corrugated boxes in the situation of pressure and protect functions of packages for the objects filled in the packages.

Test principle:

(1) Corrugated boxes compression strength test, loading to the corrugated boxes using a compression testing machine at a certain constant rate untill corrugated boxes are broken or till certain load or displacement are reached.

(2) Corrugated boxes stacking test, loading a certain force to the corrugated box using a compression testing machine untill corrugated box is broken or sustain a certain time period.

When measuring deformation of corrugated box during compression test, an original load should be set as a datum point. The datum point can refer to the following chart:

Average compression force(N)	Original force(N)
101-200	10
201-1000	25
1001-2000	100
2001-10000	250
10001-20000	1000
200001-100000	2500

2. Functions of compression testing machine

This machine is applicable to metal, cementing compound, tubes, sectional bars, aerospace, petrochemical, waterproof rolls, wire and cable, textile, fiber, rubber, ceramics, food, mechanical packaging, geo-textile, film, wood, paper and other industries and quality supervision department, and it also can be used in college for teaching demonstration.
