Get superior shot control with the industry's first 3-piece injection molding non-return valve.
Don Zeiger doesn't hate his competitors; he just doesn't understand them. Which is why - after so many years of leading the way with the gold standard
Zeiger Z4 4-piece non-return valve* - he knew he had to make a 3-piece.
Don believes general molding operations aren't getting good enough performance. He "I.D.s" the I.D. as the culprit. Competitors insist a straight-through I.D. (Inside Diameter) is fine. But only a Bellmouth I.D. can accommodate different material viscosities to provide consistent, controllable, repeatable shots.
Improved shot control gives you The Ultimate in Affordable Performance with the first advanced 3-piece screw-tip valve made specifically for general
injection molding operations.
Better steel, better processing:
- Zeiger Z3 Check Rings are constructed entirely of D2 tool steel hardened to 60RC.
- Corrosion resistant and abrasion resistant.
- Favorable compression strength.
- Resists denting and stands up better than all other lower grade or veneered nitrided steel.
Excellent shot control at any viscosity:
- Zeiger's exclusive design bellmouth configuration accommodates the varying needs of different material viscosities.
- Bellmouth I.D. starts narrower and becomes wider (the inside diameter of the Zeiger Check Ring is like the shape of a bellmouth) to build up pressure during the injection forward mode, pushing the Check Ring back to close the shut-off in a consistent, repeatable fashion.
- Most others use an inferior, straight-through I.D. that can only work with one type of viscosity.
Zeiger Z3 zaps all the rest! Never again settle for 3rd rate 3-piece pretenders! Don Zeiger's no Mother Nature, but he's been around long enough to learn a thing or two from her on physics and chemistry. Because of that, you win because you get the best 3-piece screw-tip valve at affordable prices, and his competitors lose. Let's learn from the inventor with...
CHECK RING PHYSICS 101!
"The check ring prevents plastic from being blown back during the injection phase of the molding cycle. It 'checks' it at the door. But in real life, different viscosities are used and that needs to be applied in the design."
SHRINKAGE!
"Just like on 'Seinfeld,' shrinkage doesn't show you in your best light. It's simple: polymers are heated --> molecules get larger --> it cools for 24 hours --> then (guess what!?!) there's post-mold shrinkage --> so without accommodating for this, you get inconsistent end products"
WE UNDERSTAND POLYMER FLOW CHARACTERISTICS. OTHERS JUST COPY US WITHOUT THAT KNOWLEDGE!
"The dynamics of polymer flow characteristics show that a straight-through I.D. can't accommodate different viscosities. That's because it's straight! We designed ours with 3 flow channels, curved, and of varied diameter. Makes sense when you think about it - and we did."
GIVE IT YOUR BEST SHOT!
"C'mon DME, IMS, and the rest of you guys. This is no secret I'm hiding. Zeiger uses our understanding of polymer flow characteristics to make a better check ring for a screw-tip that's a high-tech piece of equipment. If we would all do this, all general injection molders would get better shot control. Prove me wrong or get with Mother Nature."
