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. |
