Abstract
The invention relates to a method and an installation for processing thermoplastic synthetic materials. According to the invention, the melt strands or the like are displaced in oscillation or pulsation in order to indent or penetrate the joint lines between at least two injection strands.
Claims15
A process for the processing of a meltable material, in order to produce a molding, comprising forming flow lines with strands of the melt, vibrating or pulsing the melt strands, at least in sections, causing the melts to penetrate in a region of the flow lines owing to vibration differences, and bonding the flow lines to one another at a joint point of the melt strands.
A process comprising intermittently injecting vibrating molten strands into a mold.
A process comprising setting at least a section of a melt strand in vibration to bond at a region of a flow line with another melt strand outside a mold.
