Processing of dual color EVA composite lining

The processing of dual color EVA composite lining is a common footwear production process. By combining two different colors of EVA materials together, the lining is made, making the appearance of shoes more beautiful and fashionable. This article will provide a detailed introduction to the processing process of the dual color EVA composite lining.

Firstly, the processing of the dual color EVA composite lining requires the preparation of a series of materials and equipment. In terms of materials, it is mainly necessary to prepare two different colors of EVA materials with the same thickness and hardness to ensure that the composite lining has good strength and softness. In terms of equipment, it is mainly necessary to prepare a dual color EVA composite machine, which is a machine specifically used to composite two different colors of EVA materials together, which can improve the efficiency and quality of the composite.

During the processing of the dual color EVA composite lining, it is first necessary to prepare two different colors of EVA materials. These materials can be pre cut to the required size and shape to adapt to different types of shoes. Then, place two different colors of EVA materials in the two silos of the composite machine.

Next, turn on the power supply of the composite machine, adjust the temperature and pressure of the composite machine to adapt to the characteristics of the composite material. Generally speaking, the processing temperature of the dual color EVA composite lining is relatively high, and it is necessary to ensure that the material can fully melt and bond together. At the same time, the processing pressure should also be appropriate to ensure that the composite lining has uniform thickness and good bonding strength.

After the temperature and pressure of the composite machine are adjusted, the EVA material from the two silos is gradually fed into the composite chamber of the composite machine. In a composite chamber, two different colored EVA materials are gradually melted and bonded together through heating and pressure. In this process, it is necessary to pay attention to adjusting the speed and time of the composite machine to ensure that the composite lining has the required thickness and color distribution.

After the composite machine has processed all the EVA materials, the composite dual color EVA lining can be taken out. At this point, the lining can be cut into the desired shape and size using scissors or molds to adapt to the specific shoe design. Then, by hot pressing or bonding methods, the inner lining is fixed inside the shoe, and necessary post-processing and finishing are carried out to match the shoe surface and have a good hand feel and comfort.

In summary, the processing of dual color EVA composite lining is a common footwear production process. By combining two different colors of EVA materials together, the lining is made, making the appearance of shoes more beautiful and fashionable. During the processing, it is necessary to prepare appropriate materials and equipment, and strictly control parameters such as temperature and pressure to ensure that the composite lining has good quality and performance.
