MBO folding machines are engineered for precision folding of thin to medium-weight papers commonly used in commercial printing, such as offset paper, lightweight cardstock, and text-weight stocks. However, they are not designed to handle extremely thick or rigid materials.

• Thick board stocks: Materials like chipboard, corrugated cardboard, or heavy cover stock (typically above 300 gsm) often exceed the machine's mechanical capacity and may cause jams or damage.
• Multiple layers: Attempting to fold multiple sheets stacked together can lead to inconsistent results and strain on the machine’s feed system.
• Variable caliper: Papers with uneven thickness or irregular surfaces may not feed properly through the rollers, leading to misalignment or incomplete folds.

For best results, always consult the technical specifications of your specific MBO model—such as the MBO MB, MBO T, or MBO K series—as maximum paper thickness and feeding capabilities can vary significantly between models and configurations.

Q2: Can MBO folding machines fold paper with unusual textures or coatings?

While MBO machines are highly versatile, specialty finishes and textured papers can present unique challenges that affect fold quality and machine performance.

• Textured papers: Linen, felt, or laid finishes may grip unevenly in the feeders, increasing the risk of skewing or misfeeds during high-speed operation.
• Coated papers: High-gloss, UV-coated, or soft-touch laminated stocks can be slippery, making it difficult for the machine’s grippers and rollers to maintain consistent traction.
• Adhesive coatings: Papers with partial adhesives or repositionable glue can leave residue on folding plates and rollers, requiring more frequent cleaning and maintenance.

To mitigate these issues, operators often adjust the air-assist systems, use anti-slip tapes, or modify tension settings. In some cases, pre-conditioning the fold (scoring or creasing) is recommended to prevent cracking or misalignment, especially with heavily coated stocks.

Q3: Can an MBO folding machine be used for paper of non-standard shapes and sizes?

Folding irregularly shaped or non-standard sized paper is possible but comes with important limitations and requirements.

• Size constraints: The paper must still fit within the machine’s minimum and maximum feed dimensions. Extremely narrow or oversized sheets may not be reliably gripped or transported through the folding path.
• Custom tooling: Non-standard folds—such as diagonal, curved, or asymmetric creases—often require custom folding plates, knives, and folding heads tailored to the job.
• Cutting beforehand: For optimal results, oddly shaped sheets are typically trimmed into a rectangular or manageable format before folding, ensuring smooth feeding and alignment.
• Registration challenges: Irregular edges can interfere with the machine’s optical registration systems, increasing the risk of misalignment and inconsistent fold placement.

Many print shops work closely with MBO technicians to develop job-specific setups when handling unique formats, especially for high-value specialty printing projects like luxury packaging or artistic brochures.

Q4: Can MBO folding machines be used for other materials besides paper?

MBO folding machines are precision-engineered for paper-based substrates and are not recommended for use with non-paper materials due to potential operational and mechanical risks.

• Cardstock and paperboard: These are generally acceptable if within the machine's specified thickness and flexibility range (usually up to 300–350 gsm).
• Plastic sheets: Thin plastics like polyester or polypropylene may seem foldable, but their elasticity and low surface friction can lead to slippage, inaccurate folds, and static buildup that disrupts feeding.
• Foil or metallized materials: These can abrade rollers, damage folding blades, and create conductive hazards in the machine’s electronic components.
• Composite materials: Laminates or mixed-material substrates may delaminate during folding, leaving debris inside the machine and compromising future jobs.

Using inappropriate materials not only risks damaging expensive components like folding plates, belts, and sensors but may also void the manufacturer’s warranty. For folding non-paper materials, dedicated industrial folding systems designed for those substrates are strongly advised.
