Sandwich-Die
Sandwich-Die
The Sandwich Die is a die-cutting tool with a unique structure, typically composed of multiple layers of materials,
including top and bottom die layers with an intermediate cushion layer, forming a sandwich-like structure.
Main Structure of the Sandwich Die
1. Upper Die (Top Plate)
- Made of metal sheets or hard synthetic materials, it primarily supports and secures the blade.
- Precise cutting and installation design ensure the stability of the blade's position, preventing misalignment.
2. Intermediate Layer (Spacer/Support Layer)
-
This core layer, made from high-strength materials like steel, aluminum, or engineering plastics, provides stable support for the blade.
-
Elastic materials may also be used to reduce blade deformation under pressure and enhance die-cutting stability.
-
The middle layer can be customized for die-cutting needs, such as local reinforcement or pressure reduction, to suit different material cutting requirements.
3.Lower Die Plate (Bottom Plate)
-
Similar to the upper die plate, its main function is to secure the blade and provide corresponding support.
-
This layer may also include elastic pads or special structures to reduce impact on the material being die-cut, preventing deformation.
The advantages of Sandwich Die include :
1. Improved Die-Cutting Precision
-
Due to its sandwich design, it effectively stabilizes the blade, reducing blade movement and enhancing die-cutting accuracy.
-
Ideal for applications requiring high precision die-cutting, such as electronic products, medical devices, and optical films.
2. Extended Die-Life
-
The sandwich die structure helps evenly distribute cutting pressure, reducing blade wear and deformation.
-
Avoids excessive pressure on a single blade, improving overall durability.
3. Compatible with a wide range of materials
-
Suitable for die-cutting various materials such as foam, double-sided tape, PET, PVC, copper foil, and aluminum foil.
-
Especially suitable for die-cutting precision films and multilayer materials, ensuring accurate cutting of each layer.
4. Enhances production efficiency
-
With better blade stability, it reduces rework caused by precision issues, improving overall production yield.
-
The layered structure reduces the pressure required on the machine, enhancing die-cutting stability and speed.
5. Reduces die-cutting dust and burrs
-
Even blade pressure reduces burrs and dust caused by uneven material stress, making it ideal for high-precision applications.
-
Improve the quality of die-cut products and reduce post-processing costs.
6. Easy to Replace and Maintain
-
Some sandwich die designs allow for blade or internal structure replacement, reducing maintenance costs.
-
The blade configuration can be adjusted based on different die-cutting needs, enhancing the flexibility of the die.
