Many people only know that sponges can be used for washing dishes, but few people know that sponge is also a very good packing lining material. Sponge is a light, anti - fall, shock resistant and fireproof product. The sponge has a very unique processing method, easy to form, and can be made into the shape that you want to make. Today, the EVA lining manufacturers tell you about sponge shaped machining methods.
1. one hole forming method
As a sponge lining, it is possible to use a single hole forming method. The method is to use the steel film to dig out the required part, then the hand push machine is up to the depth, cut off the excess sponge. Sponge lining is a relatively high-end and exquisite product.
2. plane punching and sticking machining
It is a processing method made of the shape of the tool die made of the product and then flushing, which is often used in the packaging industry, and the different thickness can be used to produce different products.
The method of hollowing inside the 3. sponge
This is made of electric hot wire, which is first made of mold and then fired, and has very many radians. It is often used in the sponge cover of the microphone and the sponge cover.
Special-shaped processing of 4. wire cutting sponges
As a three-dimensional 3D type arc cutting, it can be cut into different shapes according to the requirements of drawings, and it is very precise. The processed sponge products are usually used as a foil for some stereoscopic products, or as models.
The above is the EVA lining manufacturers on the spongy special-shaped processing methods, different sponge products, different requirements have different processing methods, according to the requirements of the customer to choose the most suitable processing methods.
