Premier produces permanent mold castings using four methods. This versatility can best serve each application and various casting designs.
Low Pressure
Air pressure is used to force molten metal upward into a closed die cavity. This is an excellent process for circular designs as well as pressure tight vessels. These castings approach the surface finish of die castings and create a denser casting, without the higher tooling cost.
Tilt Pour
Molten metal is transferred from a holding cup into the mold in a precise microprocessor controlled sequence. This method offers high quality consistent parts to the widest variety of sizes and shapes.
Static Pour
Molten metal is ladle-poured from the top directly into a die cavity. This method is normally used for center-feed castings and accommodates a wide range of small to large castings.
Semi-Permanent Mold
Preformed sand cores are used with the methods described above. This allows casting of internal shapes, features or undercuts when “hard tooling” is not the best option.
