Moldman Systems LLC

Moldman Systems 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 Systems are designed exclusively for Low Pressure Molding. They are integrated, purpose built LPM machines, designed without maintenance intensive items.

  • No heated hoses
