Ways to
EXTEND
EQUIPMENT LIFE

Pricing and Specifications

Have worn barrels been robbing your profits?

Can’t afford any lengthy downtime right now? Installing an IMS BRODY-ring® on your existing screw tip (or replacing it with a new IMS Screw Tip with BRODY-ring) will not only help you regain control of part quality, but will also let you postpone barrel repairs until after your job is complete.

The introduction of the BRODY-ring, originally called the IMS Barrel Life Extender, in the early 80’s was a major breakthrough in improving reciprocating-screw press efficiency. Today it remains a valuable tool for safe-guarding your job profits.

The simple installation of a Screw Tip BRODY-ring for use...

IN WORN BARRELS

Extends barrel life from 3 to 9 months – or more!
Requires less downtime and lets you postpone barrel repairs until job runs are complete or to a more convenient time
Restores new press performance (or better) on ANY injection molding machine

This BRODY-ring ran 11 months and 13 days starting in a barrel worn 15 thousandths oversize.

IN NEW BARRELS

Extends barrel life 2-3 times
Lets you mold with a consistent cushion. This ensures perfect fills every time. It maximizes part strength and lets you hold critical part dimensions more closely because you exert the same pressure on every shot.
Stops the jetting back of plastic around the O.D. of the sliding ring or tip body. This reduces unwanted frictional heat created by the plastic as it leaks back around the tip while you are trying to fill the part.
Eliminates the need to over-stoke (or over retract) your screw to compensate for all the plastic that leaks back past ordinary tips. Shortening your screw stroke, in turn, shortens cycle times.

In a hurry? IMS BRODY-rings will help restore/enhance the performance of any barrel in far less time and at much lower cost then complete barrel re-lining or replacement!

How to order

You may order a BRODY-ring(s) from IMS and grind the groove in your own tip (any make or style). Many popular sizes rings are in stock for same day shipment. Most custom sizes are available in just 24 hours. Instructions showing all the necessary groove dimensions you will need are provided.
You can order a New IMS Screw Tip with BRODY-ring already installed. Delivering is quoted on request.

What makes a BRODY-ring seal? It was Pat Brody’s (inventor) idea of letting the plastic force the ring against the barrel that culminated the many experiments which led to the success of his concept. This is accomplished by using a diagonal slot between the ends of the ring. The ring does not entirely close as with automotive piston rings. While some plastic can get through it, still, the gap is so small compared to the circumference of the ring, that one can safely say that no significant blow-back occurs. It is this gap that allows the plastic pressure under the ring to expand it. This makes the BRODY-ring seal work to stop blow-back, even in barrels with wear up to .025 in.
