How should magnetic material die-cutting be done? Let me give you a detailed introduction on the specific steps.
This material is primarily presented in the form of sheets, with thin thickness, heavy quality, and high fragility. Even a slight force when lifted with fingers can cause it to split. Under conventional stress conditions, the splitting does not occur along the direction of the applied force. To halt the double-layer edging like graphite sheets, the main difficulties in die-cutting magnetic materials are as follows:
1. It is difficult to extract and feed raw materials;
2. How to complete batch automated chip mounting operations;
3. The demand is to discontinue positioning die-cutting, avoid gaps, and use black adhesive for bonding, as effective positioning cannot be achieved;
4. When drilling holes in the middle of the product, it is necessary to perform full-section punching, which is difficult to arrange waste and affects the lifespan of the cutting tool;
5. The handles need to be differentiated by color and die-cut.
How to perform die-cutting on magnetic materials, given the difficulty in processing these materials? Today, we will provide a technical analysis of ferrite die-cutting processes. If you have any better suggestions, please leave a comment and share with us!
Ferrite die-cutting steps
1. Composite ferrite material
The three-station laminating machine covers the ferrite material with the following structure: an upper protective film layer - single-sided adhesive - crushed ferrite material - double-sided adhesive - a bottom protective film layer.
2. Punching and cutting of product inner holes
After passing through the three-station laminating machine, the product enters the high-speed die-cutting machine, where the inner holes and outer borders of the product are punched and cut.
3. Overlapping handle Mylar
After the product is die-cut with positioning holes and an outer frame by the high-speed die-cutting machine, it enters the three-station laminating machine, where the outer frame is discarded and the handle is covered with a film!
4. Punch and cut the outer frame of the full-page material
After folding and lifting the handle, the material is reversed and enters the high-speed die-cutting machine for the second cut - the entire outer frame and handle of the product!
5. Forming of waste-discharging outer frame slices
After die-cutting, the material enters the second-station laminating machine to eliminate waste and align the outer frame of the full-page product! Then, the product enters the slitter, where electromagnetic induction is used to cut and shape it into sheets!
