For Injection Molding and Extrusion Machines

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.

Delivery Options: Standard or Expedited delivery leadtimes.
With machine time averaging between $100 and $500 per hour, SFP understands that time is of the essence when your machine is down. Tie Bars can be manufactured in as little as 7-10 days.

Quantity Options: Single, two-piece or four-piece.
While we encourage replacing all four bars at once, we strongly recommend replacing AT MINIMUM two pieces.

We understand that end users usually contact the machine OEM when they experience a Tie Bar breakage...It's the BIG BOLD name on the side of the machine so why wouldn't you?? SFP wants to let you know that the OEM is not your only resource. If you look at the following Pros & Cons chart, we think you'll understand why we're so confident that you should contact us for your Tie Bar needs.
