Some Manufacturing Faults of EVA sole

Ethylene Vinyl Acetate (EVA) is a thermoplastic elastomer widely used in the footwear industry to produce outsoles and midsoles for sneakers and other types of shoes.
The manufacturing process of EVA soles involves injecting EVA pellets into a heated mold, which then expands and forms a foam rubber. Here are some common manufacturing faults of EVA soles:

Poor dimensional stability: EVA soles are prone to shrinkage and deformation due to their low melting point.

Limited appearance: EVA soles have limited color consistency and cannot be integrated with other materials such as TPU.

Poor durability: EVA soles are less durable than other materials such as rubber and can wear out quickly.

Inconsistent quality: The quality of EVA soles can vary depending on the manufacturing process and the quality of the raw materials used.
