3D Injection-Compression Molding

2018-11-2 · stage is the same as the injection-molding case. Injection is stopped when 107% of the final cavity volume (or about 55% of the initial cavity volume before compression) is filled, and the process is then switched to compression. The maximum press force (compression tonnage) is 50 tons and press compression time is 10 seconds.

Clamp Tonnage: More Is Better small tonnage injection molding press Right? | Plastics

In addition to lower tonnage, the probability of molding sinks, short shots, or out-of-tolerance parts is reduced. Next, we need to evaluate the gate size as well as the number of gates. A larger gate diameter has a much larger area for material to flow through, thus requiring less pressure from the injection unit to fill and pack the part.

Determining the Press Tonnage on a New Custom

2020-12-21 · Measuring Press Size. Press size, when talking about plastic injection molding machines, means more than width, height, and depth. It's measured in tons, and specifies the amount of clamping force the machine can apply to keep the mold closed during the injection. HTI has presses ranging from 50 to 950 tons. Why Is There Different Press Tonnage?

How to Calculate the Right Press Size for Injection

Calculating Tonnage for Injection Molding. To calculate the correct tonnage for injection molding, there are three critical steps: surface area, melt flow, and part depth dimension. Finding the correct tonnage is critical in the molding manufacturing process, as using the wrong machine and clamp rate can damage the final part or product.

Setting Correct Clamp Tonnage in Injection Molding

2021-1-2 · T = A x cf. For example, the projected area of the molded part is 150 sq/in times a clamp factor of 3 (tonnage needed/square inch from material data sheet). 150 x 3 = 450 tons needed. If you are running in a 500-ton press, try starting at 450 tons. The lower tonnage will be easier on the whole mold, especially the parting line and vents.
