Hot Press for Rubber Compression Molding

Compression molding is the simplest of the three, as you load the Hot Press for Rubber into the cavity, close the tool, squeeze out the excess, and fix it. It is good for low to medium-volume portions.

Such molds are made of steel or aluminum. The shape of the part is cut into the mold. The tool is driven into a hydraulic press, which is a hot plate. The Hot Press for Rubber has to be held at high pressure and high temperature. The plates can be heated by electric heating elements or hot oil or steam. The stern rubber uses all electrically heated platens. Parts are usually cured at 300 to 350 degrees Fahrenheit.

The tool is heated through simple contact with the press plates. The rubber is loaded into the cavity of the mold, and the tool is closed. Any excess rubber is squeezed out of the cavity. Presses run at high pressures, pressures from 10 to 1000 tons.

The device is kept off for 5 to 15 minutes, depending on the small .jpg of the compass. When the curing time is complete, the instrument is opened and the part is removed.

Advantages of Hot Press for Rubber include low-cost tooling and being good for short production runs. It does not use gates, sprues, or runners, which consume excess material, and may be detached from cosmetic requirements. This is a good way to produce large parts that take significant amounts of material to manufacture.
