Large Part Injection Molding

Molding machine sizes from 85 to 1500 tons. 20 Pound part weight.

High Pressure Injection Molding

Injection Molding is a thin wall, high pressure injection molding process. Plastic resin is heated in the barrel of the machine, then injected into the mold under high pressure. This pressure is held during the cooling cycle and reduced before mold opens. Parts designed for injection molding must follow design guide rules carefully or parts will have sinks and warpage

Structural Foam Molding

Structural Foam Molding is a low-pressure process. A short shot of plastic is mixed with a foaming agent and then injected into the mold. As the plastic enters the mold it begins to expand filling the mold. There is no pressure created by the injection unit of the machine to pack out the part. The foaming action is what’s used to fill the mold.

Gas Assisted Injection Molding

Gas Assisted Injection Molding is an innovative process invented around 1985. Gas is injected into a mold that has been partially filled with plastic called a short shot. The gas can be injected either through the nozzle or with a gas pin inside the mold. The gas takes the path of least flow resistance to core out the center of the thickest sections of the molded part, pushing the molten plastics further into the mold until the mold is fully filled. The gas is then used to create the packing pressure to stop the plastic material from sinking. This pressure is held through the entire cooling phase of the molding cycle and vented out of the mold before it opens
