Melt accumulator for inserting viscous melt in mold tool, has cylinder, in which piston is movably guided, where piston has front surface for impinging melt in melt accumulator

摘要

The melt accumulator has a cylinder (10), in which a piston (12) is movably guided, where the piston has a front surface for impinging the melt in the melt accumulator. The front surface is movable relative to the cylinder. The piston is arranged such that the effective surface of the movable front surface is changed.
