Several factors influence the lifespan of a die cutter, including the type of substrate being die-cut, the kind of ink used on the material, and the maintenance practices followed. For instance, if metallic inks like gold or silver are used, the cutting process can significantly increase blade wear. The round die cutter's holding points require a large investment and are prone to damage, so proper handling and care are essential for long-term use. Here are some recommended methods to ensure optimal performance and longevity:
First, transportation
When moving die cutters, it is crucial to use strong, appropriately sized boxes. Each box should contain only one die cutter. The surface should be covered with foam to protect the blade. The short shafts at both ends must be wrapped with wooden blocks that have holes, and these blocks should be fixed within the box to prevent movement during transit. Straps should be used to secure the outside of the box, and the word "fragile" should be clearly marked to draw attention and ensure careful handling.
Second, storage
Store die cutters in a cool, dry area away from moisture and direct sunlight. To protect the blade, apply a thin layer of engine oil using a nylon brush near the edge. Always use the original packaging provided by the manufacturer to prevent the blades from touching any internal parts. Wrapping the die cutter in foam plastic adds an extra layer of protection. Make sure the support blocks in the box rest on the short shafts rather than the blade itself.
Third, lifting and handling
When lifting or moving the die cutter in the workshop, cover the surface with a cloth to avoid scratches or damage to the blade. Be cautious when installing other components to prevent them from falling onto the die cutter, which could cause serious damage.
Fourth, usage and maintenance
During operation, always apply even pressure to avoid uneven wear. Cover the die cutter’s surface to reduce impact and allow small paper scraps to be ejected easily. Regularly monitor the condition of the gear and replace it as needed. Manufacturers often design the die cutter’s gear slightly softer than the anvil roller’s to ensure that the die cutter’s gear wears first, saving costs on more expensive and difficult-to-replace anvil rollers. This is similar to the relationship between plate cylinder gears and impression cylinder gears, where the former is easier to replace.
It’s also important to maintain the roller scraping felt according to the manufacturer’s recommendations and apply lubricant daily. This keeps the die cutter roll shoulder and the anvil roll clean, forming a thin protective oil film that enhances the durability of the cutting edge and the anvil roller.
Fifth, record-keeping
Develop a habit of keeping detailed records, such as the number of die cuts performed, the return date of the die cutter, the condition of the paper being cut, and whether metallic inks were used. These records help determine when to sharpen the die cutter or order a new one, preventing production delays and unnecessary waste.
