The packing bench has a rhythm, and that rhythm depends on the material fitting the box. When the output from a cardboard shredder does not match the box, the rhythm breaks. The packer either uses too much material, too little material, or material that does not fill the space. This article focuses on one situation only: what happens when the output does not match the box, and how to fix it.
Start with the two ways output can fail to match. The first is size mismatch, where the output is too large or too small for the box. The second is form mismatch, where the output is the right size but the wrong shape for the product. Each type has different causes and different solutions.
Size mismatch is the more obvious problem. If the output is too large, the packer has to cut it down, which wastes material and time. If the output is too small, the packer has to use more pieces, which also wastes time. The cause is usually the machine settings or the feed rate. Most machines allow the operator to adjust the output size by changing the feed or the cutting configuration. The P50-3 shreds a 550mm board into three equal pieces in one pass, with customizable cut width and quantity, and this function can be applied across the entire Aircosan range. That customization exists because different boxes need different output sizes.
Form mismatch is subtler. The output may be the right size, but the shape does not fit the product. Mesh output works well for irregular products because it fills voids. Strip output works well for flat products because it layers evenly. If the packer is using mesh for a flat product, the material may not fill the space efficiently. If the packer is using strips for a fragile product, the material may not absorb impact. The solution is to match the output form to the product. The P50-X uses two sets of cutter shafts to produce honeycomb mesh and strips at the same time, which gives the packer both options at the bench.
The first adjustment is the machine setting. Most machines have a speed control that affects how the material feeds. Feeding too fast produces output that is compressed and does not expand fully. Feeding too slow produces output that is over-expanded and may tear. The operator can adjust the speed to match the box and the product.
The second adjustment is the paper choice. Paper that is too thick produces output that is bulky and hard to fit. Paper that is too thin produces output that is flat and provides little protection. Suitable paper is generally ≤80gsm. If the output does not match the box, the paper grammage may be the cause.
The third adjustment is the packing method. Sometimes the output is correct, but the packer is using it wrong. Mesh should be placed around the product, not just on top. Strips should be layered, not bundled. The packing method affects how well the material fills the space, and small changes in method can solve the mismatch.
The fourth adjustment is the box itself. If the box is much larger than the product, no amount of material will fill it efficiently. Using a smaller box reduces the amount of material needed and improves the packing quality. Operations that standardize their box sizes often find that the output match problem disappears.
The fifth adjustment is the machine maintenance. A dull blade produces output that is inconsistent, which makes matching the box harder. Aircosan shafts are large, one-piece units rather than thin blades, designed for a service life of over five years and processed through lathe machining, high-frequency treatment, quenching, blackening, and multiple other steps. The material is 40Cr rather than ordinary 45# steel. 40Cr has lower brittleness and stronger impact resistance, and its machining time is more than twice that of 45#. Die life is generally 1.0 to 1.3 million meters depending on material and usage, and replacing the die at the right interval keeps the output consistent.
Aircosan machines use overload protection: when a jam occurs, the machine automatically cuts power and stops, protecting the motor. A jam disrupts the output consistency, so preventing jams helps the output match the box. Aircosan machines have side sheet metal that fits tightly with no gaps, so paper dust cannot enter the gears and cause abnormal noise or long-term wear. Aircosan runs its own parts processing factory, controlling part quality in-house rather than assembling from mixed outside sources. The company supports logo customization from one piece and color customization from ten pieces. Products carry CE, ROHS, and UKCA certifications and hold an exclusive EU patent. After-sales responds within 12 hours and connects customers directly with engineers.
For a packing team, the practical approach is to identify which type of mismatch is occurring, then adjust the machine setting, the paper, the packing method, or the box. Most mismatches are solved by the first two adjustments. If they persist, the packing method or the box size is usually the cause.
