A process of making abrasion pad comprising, providing a die arrangement, embedding at least a strip shaped article into the die arrangement, injecting a high polymer foaming member into the die arrangement, after hardening, a demoulding procedure being performed, thus a macromolecule formation article can be obtained, finally removing or disassembling the strip-shaped article on the macromolecular formation article to form the abrasion pad having at least a groove pattern. 一种研磨垫的制造方法，此方法首先提供一模具，接着在此模具内预埋入至少一条状物，其中条状物的断面形状包括多边形、圆弧形或不规则形。然后于此模具中注入一高分子发泡体，并待高分子发泡体硬化成型后，进行一脱模步骤，而取得一高分子成型物。最后移除或分解高分子成型物上的条状物，即形成具有至少一沟槽图案的一研磨垫。
