Methods for producing bicycle saddles

摘要

A method for producing a bicycle saddle (10) including a cover (16), a shell (12) and a filler (14). The method is carried out by a mold (20) including an upper part (22) with a male portion (222) and a lower part (24) with a female portion (242), which are pin-jointed together. The method comprises the steps of preheating the mold (20) to a predetermined temperature; opening the mold (20); treating a layer of release agent onto the surfaces of the male portion (222) and the female portion (242); spraying a first layer of a first plastic material (40) onto the surface of the female portion (242) treated with the layer of release agent to form a cover (16); detachably coupling a shell (12) to the male portion (222); pouring a second layer of a second plastic material (60) onto the female portion (242); closing the mold (20) and holding the mold in the closed position a period of time to form the filler (14); opening the mold (20) to remove the finished saddle (10).
