The main differences between punching machines and die-cutting machines are their functions, application areas, advantages and disadvantages, and applicable materials.
Functions and application areas:
Die-cutting machines are mainly used for die-cutting (full-cutting, half-cutting), embossing and hot stamping operations of non-metallic materials, laminating, automatic waste discharge, etc. It uses steel knives, hardware molds, steel wires (or templates carved from steel plates) to apply a certain pressure through the stamping plate to roll and cut printed products or cardboard into a certain shape. Die-cutting machines are important equipment for post-printing packaging processing and molding.
Punching machines are an air jet engine that relies on the acceleration and decompression effect of high-speed oncoming air flow to work. Its structure is simple and there are no complex rotating parts like the compressor and turbine of a turbojet engine. Punching machines are mainly used to produce a variety of products by forming, shaping and cutting various materials such as metals, plastics and rubber.
Advantages and disadvantages:
The advantages of die-cutting machines include fast speed, high upper and lower precision (i.e. stable pressure), can be used for engraving knife molds or wood board molds, and are very suitable for the processing and production of some complex products with low mold costs. But its disadvantages are low pressure and small up and down stroke, which means it is not suitable for some thick products and it is not convenient to install the commonly used QDC mold or hardware mold.
The advantages of the punching machine are high pressure and high stroke, which can punch and cut some thicker products, and can be equipped with hardware molds; the mold has high precision. But its disadvantages are high noise, high cost of hardware molds, and it is not suitable for the processing and production of some complex products. For some special materials, the cross section will have burrs and unevenness.
Applicable materials:
Die-cutting machines are mainly suitable for non-metallic materials, such as self-adhesive, EVA, double-sided tape, electronics, mobile phone rubber pads, etc.
Punching machines are more suitable for the forming and cutting of metal materials, and can also process materials such as plastics and rubber.
