(2) The ejection force should be applied to the part with the strongest rigidity and strength of a plastic product (avoiding action on the thin section), and the active surface should also be as large as possible, such as the outstanding flange, the rib and the wall edge of the shell, etc. Most barrel-shaped products are released by using the ejector plates. less

After several attempts to correct the problems did you give up and choose a metal instead?
Would it surprise you to know that many plastic parts don’t make it to market with the part properties originally intended? Did you ever ask yourself what caused this failure?

This results in:

Presses can run in size from less than 5 tons of clamping pressure to over 4000. The higher the press ton rating, the larger the machine.

Below, we outline some of the most important aspects to consider when you design for plastic injection molding.

Once the initial costs have been paid the price per unit during injection molded manufacturing is extremely low. The price also tends to drop drastically as more parts are produced. Other advantages include the following:
