Protective film die - cutting

Product Introduction:
The film die - cutting process indeed has significant advantages, making it the preferred technology for precision cutting of protective films, such as mobile phone screen films, protective films for electronic product components, automotive paint protection films, and home appliance panel films.
Product Features:
● Ultra - high Precision and Consistency: By using precision molds (die - cutting blades), it can cut complex shapes (including inner holes, irregular contours, small notches, etc.) with extreme accuracy. The tolerance can usually reach ±0.1mm or even smaller.
● Excellent Edge Quality: The sharp die - cutting knives can produce clean and smooth cutting edges, reducing or eliminating burrs.
● High Efficiency and High Productivity: Die - cutting machines (flat - bed die - cutters, rotary die - cutters, laser die - cutters, etc.) can achieve high - speed continuous production, far exceeding manual or laser cutting (single - point cutting). It is easy to integrate with equipment such as automatic unwinding, laminating, rewinding, waste - removing, slitting, and stacking to form a fully automatic production line, greatly improving overall efficiency and reducing labor costs and error rates.
● Ability to Handle Complex Shapes and Multi - layer Composite Materials: It can cut extremely complex 2D shapes in one - step, meeting various product design requirements. For multi - layer composite protective films composed of base films such as PET/PE/PU, adhesive layers, and release paper/films, die - cutting can accurately cut all layers at once (or selectively cut specific layers), maintaining the alignment of each layer structure without the need for layer - by - layer processing and then combination.
● High Material Utilization: Through optimizing the die - cutter design and material layout (nesting), the amount of scraps and waste can be minimized. The die - cutting process is usually equipped with a special waste - removal system (such as ejector pins, waste - suction devices), which can efficiently remove the unwanted parts (frame waste, internal waste), leaving behind the formed products and reducing subsequent processing steps.
● Good Surface Protection: Die - cutting (especially flat - bed and rotary die - cutting) is a physical cutting process. It usually does not generate heat and molten substances (heat - affected zone) like laser cutting, avoiding yellowing, deformation, change in adhesion, or generation of pungent odors at the edges of the protective film caused by thermal damage.
● Suitable for a Variety of Materials: The die - cutting process has good adaptability to common protective film materials (PE, PET, PP, PVC, PU, various pressure - sensitive adhesives, silicone - coated release paper/films). By selecting the appropriate die - cutter (material, angle) and backing plate, different combinations of materials with various thicknesses, hardnesses, and adhesiveness can be processed.
