Distribution Data Recorder (1)

This time, it's about the importance of the distribution data recorder.

These test intensity, -Drop height and cycle of the drop test, PSD and duration of random vibration condition- is often based on the test regulation like ISO4180, ASTM-D4169 or JIS-Z0200.

However, the intensity on the regulation is not nessesarily equivalent to the actual disribution environment.
If regulation intensity is over the distribution feild, the designed package will be over-packaged since it takes too expensive cost by many cushion materials.

Distribution data recorder has been used to identify the distribution environment to derive the optimal test condition.
It means to realize the opitimal package design.

As you see, to realize the optimal package design is very important and to meet the demand, we have been providing the data recorder, model DER-1000.

Step of optimal package design for distribution

In distribution, the freight is always encountered various hazards, like a shock event of man-handling, vibration on track board or the static compression in the warehouse.

One of the function of package is to protect the inside goods from various hazards in the distriburion environment.
So, package test has been carried out to evaluate the protectively of package design with some test equipments, such as the drop tester, vibration tester, etc.

Here, the protective package technique is widely known as the way to realized optimal package design.
Concrete steps are as follows,

1)Measurement of the distribution
 To difine the optimal test intensity from distribution hazard data with the distribution data recorder
2)Fragility test of the procuts
 To difine the critical acceleration when the product is broken with shock machine
3)Cushion material test
 To realize the cushion characteristics, such as peak accleration and max displacement of cushion material with the cushion tester
4)Evalutation test for package design toward distribution hazards
 The evaluation of the shock absorb charactarictics by drop tester, confirmation of the vibration resonance using the ocillator and the compression strength of the freight box using the compression machine, etc.

Introduction

I am Kazuaki Kawaguchi, Shinyei Technology corp. in Japan.

Shinyei Technology, brand name is Yoshida Seiki, produces some test equipments for package freight such as drop tester, shock machine, distribution recorder and acceleration mesurement system.

So, it is very important for us to learn the feild of distribution package.
In this blog, I will write about techniques of distribution package using our equipments.
