Abstract
PURPOSE: To provide buffer for packing for radio instrument and the like having dense portion and coarse portion manufactured by filling foaming materials of different magnifying power of foaming from fixed die into the space between fixed die and movable die.
CONSTITUTION: Hopper 1 and 2 is filled by foaming agent which finished primary foaming and having 50 times and 60 times of magnifying power of foaming respectively, and these agents are transferred through filling port 4 and 5 into the space between fixed die 3 and movable die 8. Then the foaming agent causes secondary foaming is moulded into predeterminded configuration by heating with steam sent from steam feeding pipe 9, 10 in the direction of arrow A. Subsequently, movable die is separatingly moved from fixed die 3 and eject pin 6, 7 are pushed into the direction of arrow B, then the buffer for packing 11 is withdrawn from fixed die 3. Obtained buffer 11 is moulded so as to have upper dense portion and lower coarse portion, therefore, dense portion may be used to contact with the heavyer portion of the instrument to be packed.
