Overview

The GA-8000 is the third step of a steel-strip plywood box line. Strip length, width and clip configuration are entered on the touchscreen; the die assembly punches and cuts each strip to the preset length, and it discharges automatically for the pressing stage. It runs an OMRON PLC with INOVANCE servo drive and a guide-bushing die assembly covered by a six-year warranty.

What a steel edge plywood box machine does

A steel-strip plywood box is built in five steps: the board is cut to size, the board is punched on a buckle machine, the steel strip is produced, the strip is wrapped over the punched board and pressed, and the finished panels are assembled into a box. The GA-8000 is the third step. It makes the strip that does the holding.

Strip length, strip width and the clip configuration are entered on the touchscreen. The die assembly punches the clips into the coiled steel strip, the strip is cut at the set length, and the finished edge discharges automatically for the pressing stage.

Inside the die assembly

The working parts are a guide-bushing die assembly, an SKD51 punch and a press rail machined from die steel. The rail runs at roughly twice the hardness of ordinary carbon steel. That is what keeps the strip aligned when the punch comes down, and what stops the rail itself wearing a groove after months of running.

The die assembly carries a six-year warranty. On a steel strip machine the die is the part that decides how long the machine stays accurate, so it is the number worth asking about before anything else on the spec sheet.

In practice a machine of this layout is judged on two things: whether the clips come out identical from the first strip to the thousandth, and how quickly the die can be changed when the box specification changes.

Cutting to length

Length is set on the touchscreen. An encoder measures the strip as it travels and triggers the cut once the preset value is reached, so every edge leaves at the same length instead of being measured by hand.

Consistent length is what makes downstream pressing predictable. Edges that vary force the operator to re-fit each one before the press closes, which is where most of the time in a manual line goes.

Changing to a different box specification

A different box needs a different strip: a different length, a different width, a different clip spacing. Length, width and clip configuration are typed in on the touchscreen; a different clip pattern means a different die set.

Because the feeder, the drive and the cut-off stay where they are, one GA-8000 can cover several box sizes on the same floor without a second machine beside it.

Control and operation

The machine runs an OMRON PLC with INOVANCE servo drive and servo motor. Settings are entered on a touchscreen, and faults surface as prompts on that same screen rather than as codes on a separate panel.

The working area sits behind a protective cover in a whole-machine dust-resistant design. Electrical components are CHINT, proximity switches are XINLING, the fasteners are 304 stainless steel and the springs are DAIDO. Rated power is 6 kW.

Where this steel edge box machine sits in the line

Upstream is the DA-8000 buckle machine, which punches the board. Downstream is the GA-2.5M hydraulic press, which folds the strip over the punched board and closes it under 30 tonnes of pressure. The GA-8000 sits between them, and the three are quoted as one matched steel edge box machinery set rather than as separate units picked off a list.

It occupies a recommended floor space of 5 x 2 m, and the machine itself measures 3,100 x 800 x 1,600 mm. A feeder and a feed support stand are included; the hydraulic press is a separate unit.

Key advantages

Six-year die warranty

The guide-bushing die assembly is covered for six years.

Hardened working parts

SKD51 punch steel on a die-steel press rail at twice the hardness of ordinary carbon steel.

Parameters, not guesswork

Strip length, strip width and clip configuration are entered on the touchscreen.

Repeatable length

The encoder triggers the cut at the preset value, so every strip comes out the same.

Dust-protected build

Whole-machine dust-resistant design with a protective cover over the working area.

Equipment questions

We do not publish prices, because the configuration changes with your box sizes, panel thickness and destination. The line is supplied as three matched machines — the DA-8000 buckle machine, the GA-8000 steel-edge forming machine and the Steel-Edge Hydraulic Press — and every figure in a quotation is listed line by line. Send your box sizes and target output and you will get a written quotation against them.
