EVA foam is made from the copolymerization of ethylene (E) and vinyl acetate (VA), which is a common laser cutting material. The full name of EVA is Ethylene Vinyl Acetate.
EVA foam is a new type of plastic environmentally friendly foaming material that comes with the advantages of good moisture resistance, heat insulation, shock resistance, buffering, and resistance to chemical corrosion. It is resistant to water, grease, acid and alkali, non-toxic, odorless, and pollution-free.
EVA foam is used in the assembly and packaging of air conditioners, refrigerators, freezers, household appliances, engineering refrigeration, furniture, automobiles and household appliances, as well as the production of gaskets, floor mats, medical equipment and shoe materials.
With the widespread use of EVA foam materials, many product packaging have begun to use this material. Because the cost is relatively low and it is very durable, it is very suitable as a product cushioning material.
However, at this level, rough machining is definitely not enough, and more sophisticated cutting tools will inevitably appear.
In traditional processing, manual foam cutting machines have been the mainstream for a long time. Through preliminary design and outline, relatively simple cutting is performed according to the design.
This kind of cutting is very effective for rough processing of products. Since the hardness of the foam pad itself is not high, the blade loss is very small, and the advantage it brings is very obvious, that is, the cost of consumables is low.
In contrast, the shortcomings of traditional processing are also very obvious. First of all, the processing is difficult. When cutting, you need to use even force and do it in one go. If there is a pause and the cutter is restarted, the cross-section will inevitably be uneven.
Another disadvantage is that there are too many waste materials for fine processing. According to geometric principles, if you want to dig out a relatively complex pattern, all surrounding materials need to be cut away.
When processing fine foam products, although the cost of tool consumables is low, the cost of materials increases significantly, making it even less cost-effective in the end.
STYLECNC's CO2 laser cutting machine uses laser to cut foam in a non-contact manner, which results in smooth and clean projects, completing the cutting process in one step without the need for secondary processing.
The laser cutting method is very suitable for cutting more precise foam cutting projects. STYLECNC's CO2 laser cutter machine has the following 3 major advantages:
Automatic CNC Controller And High Precision
STYLECNC's CO2 laser foam cutting system uses a fully digital operation panel, which is controlled uniformly by a computer and can finely adjust the accuracy of each parameter. When cutting precision patterns, digital display can make the finished product uniform, and the most efficient cutting plan can effectively reduce the generation of waste materials.
Excellent Beam Quality And Power Supply Design
For a laser, beam quality is very important. The beam quality of STYLECNC's CO2 laser foam cutter machine is very superior (M2<1.2), and the most stable laser power can be obtained in any frequency range.
To obtain such excellent beam quality, precision power supply design is indispensable. STYLECNC has a very excellent design team, and the designed power supply is not only stable in power, but also has a long service life.
Small Size And Cost Saving
In addition to excellent performance, STYLECNC's CO2 laser cutting table further reduces the size of the laser through a highly integrated design. It does not need to enlarge the optical path, is quickly installed, and can be directly put into production and use. Because of its small size, it does not require a large area, which further reduces the cost and is extremely cost-effective.
