The side cleaning hole (edge cutting hole) is a circular punching hardware installed on the die-cutting cutter template, and its core function is to automatically discharge the round waste through the side bevel structure during stamping/die-cutting. Its application scenarios are concentrated in industries that require high-speed, efficient, and high-quality punching, such as printing and packaging, labels, plastic films, and precision electronics.
1. Printing and packaging industry (core application)
Color box, gift box, corrugated box: used for small round hole processing such as handle holes, ventilation holes, hanging holes, observation windows, etc.
Paper cards, tags, price tags: solve the problem of 2–6mm small aperture automatic waste discharge, especially suitable for thick jam paper and gray board paper.
Cigarette packs, medicine boxes, cosmetic boxes: meet the needs of precision die-cutting with high cleanliness, no burrs, and high life.
Three-dimensional greeting cards, 3D gift boxes, multi-layer cardboard: adapt to complex structures and multi-layer waste removal.
2. Label and self-adhesive industry
Self-adhesive labels, anti-counterfeiting labels, fragile paper labels: high-speed die-cutting with circular positioning holes, mounting holes, and easy-to-tear holes.
Electronic tags (RFID), double-sided adhesive, foam glue: small round holes are stable for waste disposal, not easy to stick to knives.
3. Plastic and film processing
PVC/PP/PE/PET film, blister box, plastic sheet: smooth round mouth after punching, no burrs, automatic waste discharge.
Insulating sheets, Mylar sheets, dust mesh, precision gaskets: high-precision, small-bore punching in the electronics industry.
4. Other materials and scenes
Leather, artificial leather, fabric, nonwovens: circular hole processing.
Automobile interior, foam, EVA, rubber gasket: thick soft material stable waste discharge.
Precision knife dies (manual knife dies, laser knife dies): Replace traditional steel holes + pull-back glue to simplify the production of knife molds.
5. Typical advantage scenarios (why use side cleaning waste holes)
Small aperture (2–8mm): Traditional waste cleaning needles cannot be installed, and the side cleaning hole can be stably discharged.
Thick materials (cardboard, gray board, plastic sheet): not easy to block holes and burst holes.
High-speed die-cutting (automatic flattening die-cutting machine): continuous production, automatic discharge of waste, no need to stop the machine to clean the waste.
High cleanliness requirements: smooth round mouth, no burrs, no paper scrap residue.
Long life and high cost performance: high hardness of the knife edge, impact resistance, and long life.
