Apparatus for manufacturing pouch

An apparatus for manufacturing a pouch includes a die in which a pair of forming grooves are formed with a partition wall therebetween in a top surface thereof; and a pair of punches disposed above the die configured to form a pair of accommodation parts in a pouch film while being respectively inserted into the pair of forming grooves in a state of pressing the pouch film, wherein a pressing surface of each of the punches, which is configured to press the pouch film, has an inclined angle that is inclined upward from one end thereof disposed at a side of the partition wall toward an opposite end thereof.

METHOD OF FILLING SIMULATED MUSCLES FOR LIMB OF CRASH TEST DUMMY FOR AUTOMOBILE

The present invention discloses a method of filling simulated muscles for a limb of an automobile crash test dummy, the simulated muscles are molded with foaming in the inner cavity of the mold; the method comprises: obtaining a filling volume of the inner cavity of the mold by using a liquid casting method, preparing an adhesive liquid film layer, preparing a filler and conducting demolding detection on the limb. Wherein step 3 is to inject the mixed filler into the inner cavity of the mold so as to be foamed in the mold to form foamed sponge, and stand until the foamed sponge is foamed to the exhaust port and does not overflow any more.
