How to Operate a Carton Compression Tester: Step by Step
This 97-second clip is a direct operation walkthrough of the computer servo control carton compressive tester from Derui. It opens on the mode-selection screen, brings the platen down onto a carton, runs one compression test through to the end, and finishes by printing the result. The two test modes are named on the panel, the platen is brought into position on screen, and the ticket at the end is the machine's own output.
What This Video Shows
The clip is an operation demonstration rather than a product tour, filmed in one take on a single machine. It is worth watching before an order because it shows the two things a specification sheet cannot: how the carton is loaded, and how the platen is brought down onto it.
What the walkthrough covers
▸ Choosing between the two test modes on the touch screen.
▸ Using the on-screen up and down keys to close the gap between the platen and the top of the carton.
▸ Starting the run and watching the platen press down and then travel at the test speed.
▸ The platen returning to its home position once the run ends.
▸ Printing the result ticket from the machine at the end.
Why the platen gap matters
In the video the test begins with the platen sitting on the top face of the carton. If the gap is still large when the run starts, part of the platen travel goes into closing that distance instead of into loading the box. The video shows the operator taking the gap down with the down key and stopping the descent just before contact, then starting the test from a platen that is already in position.
Running a Compression Test: The Steps in the Video
Step 1 · Choose the mode
The panel opens on mode selection. Two modes are offered: one that compresses the carton, and one that compresses it and then holds the load. The video takes the plain compression mode.
Step 2 · Close the platen gap
The up and down keys move the platen. In the video the distance is still too large, so the down key is held until the platen is almost in position on the carton.
Step 3 · Start the run
The descent is stopped from the screen, then the test key is pressed. The platen presses down on the carton and continues at the compression speed until the run finishes.
Step 4 · Read and print
When the run ends the platen returns to its home position. The result is then printed from the machine, which is where the clip finishes.
Two published details describe what happens between steps three and four. The compression speed is 10 ± 3 mm/min, and the machine records a serial number, a peak value, an average value and a designated holding pressure value, and retains all four. That retained set is what the ticket at the end of the video carries.
The Two Modes and What They Record
Compression mode
A single load cycle. The platen advances onto the carton and the run ends when the box collapses or when the set pressure value is reached. This is the mode the video follows from beginning to end.
Hold mode
The same load, kept on the carton for a set time at a designated pressure. The published report items include a designated holding pressure value, which is the figure this second mode exists to produce.
What runs alongside the test
The product page for this series describes travel-limit protection, overload protection and fault prompts, an English and Chinese interface, live test values shown while the run is in progress, an automatic return of the platen, and a micro-printer for immediate output. The video shows two of those directly: the platen returning home by itself, and the printer producing the ticket.
Operation-Relevant Published Specifications
| Item | Published specification | Why it matters when you run the machine |
| Capacity and units | 2 T capacity (optional). Units switchable between kg, lb and N. | Sets the largest load the machine can read, and the units the ticket prints in. |
| Resolution and accuracy | Load resolution 1/10,000; load accuracy ≤0.5%. | What the peak and average figures on the printout are worth reading against. |
| Test space | 1000 × 1200 × 1200 mm (L × W × H). | The envelope the carton has to fit inside before the platen travels at all. |
| Compression speed | 10 ± 3 mm/min. | The rate the platen advances once the run starts — one of the conditions a test method sets. |
| Report items | Serial number, peak value, average value and designated holding pressure value; all retained. | The four figures the printout carries in the video, and the ones a quality record is built from. |
| Footprint, weight and power | 1795 × 1000 × 1820 mm (L × W × H); approx. 690 kg; 220 V / 50 Hz. | Floor space, lifting on arrival, and the supply to have ready before the machine is positioned. |
| Safety devices | Overload protection, overvoltage protection and a limited-position protection device. | The limits that stop the platen at the end of its travel. The screen also carries a stop key, which the video uses to end the manual descent. |
Methods listed for this series. The product page lists TAPPI-T804, JIS-20212, ASTM-D642, QB/T1048, BS EN ISO 12048, GB/T 4857.3, GB/T 4857.4, GB/T 4857.16, GB/T 8167 and GB/T 8168. That list describes the range the machine is built to serve; the run you perform still has to follow the method your own quality system names, including its speed, its end point and its pass or fail limits.
What the Video Shows and What It Does Not
What it shows is the operator's side of the machine: where the mode is chosen, how the platen is brought down, what the screen looks like while the run is in progress, and that the result leaves the machine on paper rather than only on a screen.
What it does not show matters just as much. The clip names no test standard and no pass or fail criterion, so it is not evidence that any particular method is met, and no calibration or verification of the load cell appears in it. Those come from the records that ship with the machine, and from whichever third-party report your audit asks for.
What to Confirm Before Ordering
▸ The carton: the largest footprint and the tallest stack you need between the platens, measured against the 1000 × 1200 × 1200 mm test space.
▸ The load: the peak force your worst case produces, set against the 2 T capacity and the 1/10,000 resolution.
▸ The method: the standard, the compression speed it calls for, and whether the run ends at collapse or at a pressure held for a set time.
▸ The units and the interface: whether your operators read in kg, lb or N, and whether the English and Chinese interface covers them.
▸ The output: whether the ticket from the built-in micro-printer is enough for your records, or whether the results also have to be kept as data.
▸ The site: a 220 V / 50 Hz supply, and enough floor for a machine measuring 1795 × 1000 × 1820 mm and weighing around 690 kg.
What to Send With an Enquiry
▸ What you are testing: corrugated cartons, honeycomb boxes, paper canisters or drums, with the footprint and the height of the specimen.
▸ The stack you need to reproduce, since stacking is one of the two tests this series is built for.
▸ The standard and the conditions it sets: compression speed, end point, and whether the pressure is held.
▸ The capacity and the units your report is written in.
▸ Your site supply, and the floor space available for the machine.
Frequently Asked Questions
Video Summary
In just over a minute and a half this clip covers the whole operating sequence of a Derui carton compression tester: selecting one of the two modes, using the on-screen keys to bring the platen onto the carton, starting the test, watching the platen press down and then advance at the test speed, and printing the result once the platen has returned to its home position.
The figures behind what you see are published on the product page: a 2 T capacity with a 1/10,000 resolution and a load accuracy of ≤0.5%, a 1000 × 1200 × 1200 mm test space, a compression speed of 10 ± 3 mm/min, and a report carrying the serial number, the peak value, the average value and the designated holding pressure value. What the clip cannot tell you is whether your own standard and your own pass or fail limits are met — that is settled by the method you run and by the records that leave the factory with the machine.
