Visualize the Multishot Injection Process

Multishot technology joins two or more plastics into one solid, integrated component. This is also known as two-shot molding. To accomplish this, two resins are injected into one mold held in a rotary platen press. Precisely timed rotations and injections synchronize production. Watch video.

HERE'S HOW IT WORKS

Uniquely programmed barrels inject two different plastics. Rotary action makes continuous production possible. A single part is formed when two plastics are joined inside one cavity.

Uniquely programmed barrels inject two different plastics.

Cavities are filled in sequence with two unique resins. The resins flow from two independently programmed barrels. The first injection is usually the hard material.

Rotary action makes continuous production possible.

After the first shot of plastic is injected, the mold opens and rotates and is carefully positioned so a second shot can fill on top of the first. Finished parts are ejected from the mold. Empty cavities are then ready for the first shot of the next part.

During every molding cycle, one part receives the first shot while the other gets the second. Proper bonding is the result of proficient process control, accurate timing, and the selection of suitable materials.
