Wireless charging dedicated ferrite die cutting process introduction

What is ferrite?

Ferrite is a metallic oxide with ferromagnetic properties. In terms of electrical performance, ferrite has a much higher resistivity than metallic and alloy magnetic materials, and it also has high dielectric properties.

The magnetic performance of ferrite also shows high permeability at high frequencies. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high frequency and weak current. Due to the low magnetic energy stored in a unit volume of ferrite, the saturation magnetization intensity is also low (typically only 1/3 to 1/5 of pure iron), which limits its application in low-frequency high-power electrical fields.

Difficulties in die cutting ferrite materials

This material is basically in sheet form, with a thin thickness, relatively heavy weight, and high brittleness. It will break when you lift it with your fingers. Under normal stress conditions, the fracture does not follow the direction of the applied force. If double-sided chamfering like graphite sheets is to be performed, the main processing difficulties are as follows:

1. Difficulty in extracting and feeding raw materials;

2. How to achieve batch automatic order placement;

3. Positioning die cutting is required to avoid gaps, glue residue, and ineffective positioning;

4. The holes in the product must be punched as a whole segment, which is not easy to discharge and affects the tool's service life.

5. The handle colors must be distinguished and punched.

Ferrite die cutting process steps

1. Laminating ferrite material

A three-position laminating machine is used to laminate the ferrite material! The structure is a top protective film layer, single-sided adhesive-bonded ferrite material, double-sided adhesive tape, and the bottom layer is a bottom protective film!

2. Punching and punching the inner hole of the product

After the product passes through the three-position laminating machine, it enters the high-speed die cutting machine to punch the inner hole and outer frame of the product!

3. Polyester film die cutting and laminating the handle

After punching the positioning hole and outer frame from the high-speed die cutting machine, the product enters the three-position laminating machine to remove the waste outer frame and cover the handle!

4. Die cutting, punching, and cutting the entire material frame

After laminating the polyester film handle, flip the material and enter the high-speed die cutting machine, then punch the entire frame on the second cut and process a part of the product!

5. Die cutting, waste removal, and slicing of the outer frame

After punching, the material enters a two-position laminating machine, and waste is discharged from the frame of the entire sheet product! Finally, the product enters the slicing machine for electromagnetic induction slicing. The final product is in sheet form!

A good round knife die-cutting machine can produce high-quality ferrite sheets, making the die-cutting process smoother. 

Rotary Die Cutting of Ferrite Materials

Die cutting is a versatile manufacturing process used to shape materials efficiently and precisely. One application of die cutting is the fabrication of rotary shapes from ferrite materials.
