big tonnage plastic injection compression molding

Nov 17, 2020 · Normally, the injection molding machine clamping force rating is stated in tonnage. A 200-ton machine, for example, is capable of producing a maximum clamping force equivalent to a total of 200 tons. The clamp tonnage requirement is used to select a capable machine that will prevent part defects, such as excessive flash.

Jun 15, 2020 · Compression Molding is the simplest and most common method of rubber molding. It is characterized by placing a slightly over-sized piece of uncured rubber in the cavity then closing the press with sufficient tonnage and heat which causes the rubber to lose viscosity and flow throughout the cavity.

May 31, 2017 · Tonnage =parts area × tonnage factor = 169.28 in.2 × 3 tons/in.2 = 507.84 tons Now we have a starting point to determine what clamp tonnage is correct for this mold. But other factors must also be taken into consideration to determine if the tonnage required will be above or below 3 tons/in.2.

Compression molding is often the more economical manufacturing process when working with low volume thermoset resins. The compression molding process provides additional geometry flexibility over standard injection molding and is typically used to produce large, fairly complex parts that are unsuitable for injection molding presses. Compression molding is only compatible with a select …

In injection molding, finding the right tonnage can be tricky. Just because a moulding machine can produce a clean looking part without flash it doesn’t mean the clamp is enough. For any particular part, there are a range of clamp tonnages than can produce parts that appear to be ok.

Compression molding and injection molding are very similar, but they have one major difference. In compression molding, molds are closed around the charge, and in injection molding, the charge is injected into a closed mold cavity. Today’s manufacturers frequently use both compression and injection molding but for different types of parts.

Dec 03, 2018 · In the molding process, plastic is injected into the mold at an exceptionally high-pressure rate, which creates a natural pull to force the mold open. A press is designed to keep the mold shut with larger parts requiring more tonnage and force, and smaller parts requiring less. A general calculation for determining press size needed is as follows:
