The radial edge of the teeth must be shaped so that back pressure from the wheel forces the pawls inwards. This is done by insuring that the angle between the line from the pawl pivot to the contact point and the line of the radial portion of the tooth is less than 90 deg.

| 15. Because of the tremendous forces that may be applied during the clamping and injection portion of the cycle, the mold platens are ruggedly build. As the physical size of the press is increased, larger molds may be accommodated, and consequently the weight that may be suspended from the platen becomes greater. It should also be recognized that as the press size increases there is usually a significant increase in the clamp force that is available. The platen then, must not only be strong enough to support the tooling but also be capable of withstanding the bending or deflection action caused by the clamping force. Any serious distortion of the platen can cause the mold to flash and can lead to severe wear and damage to the press itself. | |
