Liquid silicone micro molding system

Engel North America’s liquid silicone micro molding system offers the precision of an electric injection molding unit combined with a 12 mm, specially-designed LSR screw and check disc assembly and the flexibility of a tiebarless clamp design.

Based on the Engel Victory 80/30 Electric US, the system uses Engel’s tiebarless clamp design, which provides a large, specially supported platen area combined with a specially-engineered with the flexibility to run small to large mold bases.

The electric injection unit offers the ability to run shot volumes down to fractions of a gram. The mold is a flash-p less four-cavity open nozzle medical LSR umbrella valve with a total shot size of less than 0.5 gram. The micro shot size is accomplished by using a 12 mm screw and check disc assembly specially designed for LSR, and a Kuka six-axis robot is integrated within the machine footprint for automatic part removal.

The machine also has the ability to mold a shot size up to 55 cc with a simple barrel and screw changeover. The Fluid Automation LSR dosing system is specifically designed for small shot sizes, and is mounted directly to the machine feed throat.

The LSR is configured with Engel’s Basic Clean Room package, and the machine’s paint provides special lacquering for clean room production.
