Many people are unfamiliar with die cutting processing. Today we break down its application scope and underlying working principle.
In the early stage, die cutting was only a post‑cutting process for printed products. With industrial upgrades, modern die cutting is widely adopted for electronic component manufacturing and classified as high‑precision converting. Since the industry is not well known to the public, this article explains the function of die cutting and the logic of the full process.
Die cutting is a precision converting method that cuts rolls or sheet raw materials into custom shaped components according to engineering drawings. Driven by the booming consumer electronics industry, die cutting has gone far beyond traditional print finishing and become a core production process for electronic auxiliary materials.
Backlight components: Black‑white double‑sided tape, brightness enhancement film, diffusion film, reflective film, special adhesive tapes
Adhesive products: Double‑sided & single‑sided tapes from 3M, Nitto, Sony, Tesa, Sekisui and other brands
Cushioning & protection materials: Shock absorption foam, surface protective film, anti‑static film, EVA, PORON foam
Insulating substrates: PC, PVC, PET, FORMEX insulation sheets
EMI shielding materials: Conductive foam, conductive fabric tape, copper foil tape, aluminum foil conductive tape
Custom high‑precision die‑cut components
Die cutting serves a wide range of sectors including electronics manufacturing, machinery, food packaging, medical consumables and gift packaging.
Die‑cut auxiliary materials are widely assembled inside mobile phones, laptops, cameras, copiers, portable media players, automotive electronics, instruments, communication hardware, digital accessories, medical devices and home appliances. Die‑cut parts made of different materials deliver distinct functions such as shock absorption, insulation, EMI shielding and bonding.
Die cutting machines use steel rule dies, metal stamping tools, steel wire dies or engraved plates. Constant pressure from the pressing unit punches and cuts films, sheets and adhesive materials into custom shapes.
Related converting processes:
Creasing: Steel wire indents the material to form fold lines for easy bending
Hot stamping: Male and female dies transfer printed graphics onto the material under heat
Lamination: Bond two different substrates together by heat pressing
Waste stripping: Remove excess scrap after cutting
Die cutting, creasing, hot stamping, lamination and waste stripping together form integrated die‑cut converting processes.
