    • An outer cover material forming method of a crush pad is provided to adjust depth of a cut groove easily, and to reduce manufacturing process and manufacturing cost by forming the cut groove in making the crush pad without additional laser processing or mechanical processing. A release agent is injected to a mold, and raw material of polyurethane polymer including polyol and isocyanate is injected to form an outer cover material. A mold(30) for forming a cut groove(22') in manufacturing a crush pad is placed on the half-formed outer cover less than the desired thickness, and raw material of copolymer is injected to the formed surface of the outer cover to the desired thickness. The cut groove is formed along the mold by removing the mold. The depth of the cut groove of the outer cover is adjusted easily by regulating the injection amount of raw material.
    • 提供挤压垫的外覆盖材料形成方法,以便容易地调节切槽的深度,并且通过在制造压碎垫中形成切割槽而不需要额外的激光加工或机械加工来减少制造工艺和制造成本。 将脱模剂注入模具中,并注入包含多元醇和异氰酸酯的聚氨酯聚合物的原料以形成外覆盖材料。 在制造挤压垫上形成切割槽(22')的模具(30)被放置在小于期望厚度的半成形外盖上,共聚物的原料被注入外盖的成形表面 所需厚度。 通过移除模具沿着模具形成切割槽。 通过调节原料的注入量,容易地调整外盖的切槽的深度。
