The compression strength of packaging material is vital to understanding its performance during handling and storage. We have heard about the box compression strength of the package, which refers to its fracture resistance when a downward compressive force is applied to it. Core compression strength is a similar packaging property with a little difference.
Core compression determines the side-to-side crush resistance of the composite tubes and cores when a downward compressive force is applied. And just like there is a box compression tester, there is a core compression tester. Before the sample core is tested in this tester, its core diameter, length, and thickness are measured. After that, the cores are placed in the compression tester and crushed at a load range between 0-1000 kgf/0-10000 N.
Let us know how UEC’s core compression tester works.
UEC Core Compression Tester
UEC’s core compression tester is a widely chosen and used packaging testing instrument by paper and packaging manufacturers. It accurately determines the core collapsing or rupture strength of the core pipers as well as cones.
The Instrument
The testing unit consists of an adjustable testing area that has clamping jaws to hold a sample of varied sizes and shapes. A piston operates the motorized unit and applies a constant force on the sample to crush it. The digital load indicator records the maximum peak crush value. Clamping jaws can hold core samples of 3”,4”, 5”, 6”, 12”, etc. Manufacturers can choose the clamp sizes based on their requirements. Each compression tester is approved under AS 2001.4.21 standard and performs crushing at a load range between 0-1000 kgf/0-10000 N.
Bottom Line
UEC houses a number of high-performance packaging testing machines such as a scuff tester, abrasion tester, impact testing machine, and so on. Get in touch with UEC to invest in paper, packaging, and pulp testing machines, and take your manufacturing business to next bigger level.
