MoldMan™ Machines

MoldMan™ Machines are ideal for low to high volume production quantities. They are automated single station Low Pressure Molding machines that are equipped with a pressure control system. This system controls volume and pressure independent of each other providing the flexibility to over-mold complex circuit boards and connectors.

Cooled mold platens eliminate hoses to the moldset providing easy access for loading and unloading molded components.

MoldMan™ Machines are designed exclusively for Low Pressure Molding. They are integrated, purpose built LPM machines, designed without maintenance intensive items.

  • No heated hoses
  • No exposed heated joints
  • No exposed moving injection nozzles
