    • PURPOSE: A manufacturing method of a buffer pad having a hollow part is provided to manufacture various functional buffer pads by coupling unit pads having various colors and material properties to each other. CONSTITUTION: A manufacturing method of a buffer pad(P) having a hollow part is as follows. Multiple unit pads(200) are manufactured by cutting a material(100) having multiple insertion holes(210) in a plate shape(S1). The unit pads are piled up, and multiple through holes(220) communicating with each other are formed by coaxially arranging the insertion holes(S2). A preliminary block(400) is formed by inserting rod members(300) into the through holes and protruding both ends of the rod members from the unit pads(S3). The preliminary block is put into a mold(500) and sealed(S4). A molded block(600) is formed by heating the mold having the preliminary block(S5). The molded block is separated from the mold, and the rod members are removed from the molded block(S6).
    • 目的:提供具有中空部分的缓冲垫的制造方法,通过将具有各种颜色和材料特性的单元焊盘彼此连接来制造各种功能缓冲垫。 构成:具有中空部分的缓冲垫(P)的制造方法如下。 通过切割具有板形(S1)的多个插入孔(210)的材料(100)来制造多个单元衬垫(200)。 堆叠单元垫,并且通过同轴布置插入孔(S2)形成彼此连通的多个通孔(220)。 通过将杆构件(300)插入到通孔中并且将杆构件的两端从单元垫(S3)突出来形成初步块(400)。 将预备块放入模具(500)并密封(S4)。 通过加热具有初步块的模具(S5)形成模制块(600)。 将模制块与模具分离,并将杆构件从模制块移除(S6)。

    • PURPOSE: A seat manufacturing method for a vehicle is provided to easily make seats in a desired form by foaming urethane to have different hardness, to variously secure shock-absorbing properties of the seat, and to automatize a seat producing process by removing a sponge attaching process in foam-producing the seat and improve productivity. CONSTITUTION: A seat manufacturing method for a vehicle is composed of steps of foaming first hardness polyurethane from a first hardness raw material injection port into a lower mold(D) at a constant thickness and forming a first hardness polyurethane layer(U1); foaming second hardness polyurethane from a second hardness raw material injection port into the first hardness polyurethane layer in the lower mold at the constant thickness and forming a second hardness polyurethane layer(U2); and foaming third hardness polyurethane from a third hardness raw material injection port(N3) into the second hardness polyurethane layer in the lower mold at the constant thickness and forming a third hardness polyurethane layer(U3). Consequently, the seat has shock absorbing performance and firmness by polyurethane layers having different hardness.
    • 目的:提供一种用于车辆的座椅制造方法,通过发泡聚氨酯容易地使座椅成为具有不同硬度的座椅,以便各种地确保座椅的冲击吸收性能,并且通过去除海绵附着物来自动化座椅制造过程 泡沫生产座椅的过程和提高生产率。 构成:车辆的座椅制造方法包括以下步骤:将第一硬度聚氨酯从第一硬度原料注入口以恒定厚度发泡到下模具(D)中并形成第一硬度聚氨酯层(U1)的步骤; 从第二硬度原料注入口将第二硬度聚氨酯发泡到下模具中的第一硬度聚氨酯层,并形成第二硬度聚氨酯层(U2); 并从第三硬度原料注入口(N3)将第三硬度聚氨酯从第三硬度原料注入口(N3)发泡到下模具中的第二硬度聚氨酯层,并形成第三硬度聚氨酯层(U3)。 因此,座椅具有不同硬度的聚氨酯层的冲击吸收性能和坚固性。
