Clamp Tonnage & Injection Molding Pressure

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.

Rubber Molding: Compression Molding

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.

Compression Molding

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 …

Compression Molding - an overview - ScienceDirect

A typical compression molding process is performed at a mold temperature of 350°F and mold pressure of 100 psi (180°C and 700 kPa) with curing time of 3 min. After the material is cured, the mold is opened and the plastic package is pushed out. Compression molding is a low cost process and is capable of high volume production.

Molding Defects, their Causes and Remedies. Part 2

Being fluid, the molten plastic solidifies in a state that shows the wavy folds of the jet stream on the surface of the injection molded part. Causes: Jetting occurs mostly when the melt temperature is too low and the viscosity of the molten plastic becomes too high, thereby increasing the resistance of its flow through the mold.
