During mold clamp-up, Tie Bars resist the strain created by the hydraulic cylinder clamping against the stationary mold. Eventually, after some time, Tie Bars break from the continuous stretching and pressure they are subject to. This is inevitable and unavoidable. While only one bar may break, this is typically a good indicator that all four bars need to be replaced.

Now that your Tie Bar is broken, Services for Plastics can provide you with multiple options to get your machine back up and running.

Material Options: We use only the best stress-proof materials.
1045, 1144 stress-proof, 4140 pre-hardened, 4340 pre-hardened. Materials are turned, ground, polished and can be chrome-plated.
