A regulated twin-screw process uses self-heating and 300°C-plus hot zones to raise recycled polyethylene melt index without peroxides.

Movable sonotrode and anvil joints adapt gap width and tool angle to maintain welding pressure and energy across variable composite seams.

A neck-to-body angle of 80° to 100°, combined with stretching and temperature adjustment, supports lighter resin containers and consistent molding.

A movable core or die varies parison thickness during extrusion to form continuous inner-surface unevenness in containers.

Centrifugal molding combines new reinforcement fibers with recycled laminar material to form stable composite hollow poles.

See how compact rotary carriers add forming stations for plastic container blow molding, reducing cleanroom footprint while maintaining sterile conditions.

Cold spraying adds a hermetic metal layer to composite mould tools, preserving vacuum integrity without welding distortion.

Torsional ultrasonic vibrations join workpieces with different melting points while limiting force-related damage to pressure-sensitive layers.

A polyolefin blend with impact modifier, fluoropolymer, clarifying, and dispersing agents improves EBM bottle transparency, haze, and gloss.

Phase change material stores and releases heat during shoe foaming to stabilize dimensions and shorten cooling and shrinkage time.
