During the customized insoles production, we have to hand sand the insoles products edge, arch, heel and other part, so to fit for customers’ feet and meet the demands totally, such as special orthotic insoles.
Sometimes, customer may send requirements to ship the semi product and have them to be re processed with other component, like eva gluing layer, so the products are asked further napping finish for convenience and reliability of process.
In additional, to ensure the adhesion of the shell and main body when manufacturing tpu / pu insoles, we should have to ruin the top surface which will be glued firstly.
