sponge foam machineThe sponge foaming machine was a machine used to produce sponge products. There are many companies specializing in the production of sponge foaming machinery and equipment, such as Henan Province Chendeyu Machinery Equipment Co., Ltd., Wenzhou City Huamin Polyfoam Equipment Machinery Factory, Handan City Wei County Yongfeng Machinery Manufacturing Co., Ltd., etc. The sponge foaming machinery produced by these companies included sponge round foam vertical foaming machines, assembly line foaming machines, punching machines, etc. These devices had the advantages of exquisite appearance, small size, simple operation, uniform and fine pore size of the foam produced, and high yield of foam. They could greatly reduce the production cost of the sponge. In addition, there was also a company called Eris Machinery Manufacturing Co., Ltd., which specialized in producing sponge foaming machines, sponge cutting machines, and other sponge machinery and equipment. The company's products had unique performance and appearance. In summary, sponge foaming machinery is the key equipment used to produce sponge products, and there are many companies in the market that provide related products.

How is the sponge made?Sponges were divided into biological sponge and chemical sponge, and their production methods were different.
The biological sponge was a creature of the Porites, and its growth was a natural process. The body wall of a biological sponge was composed of two layers of cells, the outer layer was flat, the inner layer had flagella, and most of them had a protoplasma collar. There was also a middle layer of glue in the body wall, which contained a variety of free cells, reproductive cells, etc. There was a large hole opening (outlet) at the free end, and there were many water holes on the body wall. Seawater containing food flowed into the body through the water holes, and the inner layer of cells had flagella vibrating. The indigestible things flowed out of the body through the seawater outlet.
The chemical sponge was a soft foaming rubber made of a foaming resin, a foaming agent, and a binding agent (to make the finished product sticky). For example, a foaming sponge could be made by mixing 80 parts of ethenyl-viny-acetate-ether (Eva), 20 parts of APAO-pt-3385, 20 parts of azodidicarbamide, 19 parts of CaCO2, and 0.6 parts of dicumyl peroxide-ether together, foaming in a mold, and breaking the closed pores with mechanical force. In addition, in some foreign sponge production factories, workers would first stir the yellow foam evenly, then pour the white liquid into a large pool after stirring. After the liquid had a chemical reaction and expanded, the cutting process would be carried out. First, the huge sponge would be placed on the cutting machine to cut, and finally cut into the required rectangular shape.
