Services for Plastics, Inc. check valves are made from significantly higher quality tool steels than available through the O.E.M. Along with better quality, SFP provides customized designing of the screw tip assembly to successfully work with your brand of molding machine and type of application. And SFP offers them at significantly lower prices than the O.E.M. can offer. SFP check valves are the BEST VALUE in the industry! We stock a wide variety of brands,, plus we also can manufacture any screw tip assembly. Using your sample tip assembly, your print or a print from our extensive library, we will manufacture a screw tip assembly to match your specific requirements. Services for Plastics, Inc. check valves are available in a wide variety of tool steels to match your application.

The following brands of tip assemblies are in stock and ready to ship.

We can make any screw tip assembly!

We have an extensive CAD library consisting of thousands of prints for screw tips, barrels, screw, nozzles, end caps, etc. If you need a quote and there isn't a print available, simply send us a used sample part and specify what material you want the new one made from. (Hint: Always save your original check valves. They are valuable for verification of dimensions when ordering new assemblies.)

No one check valve design is perfect for every application; therefore, we offer three distinct designs to ensure the proper component for your application.

Design Options:

ACCU-FLO™ Design Advantages: • Excellent Design for Most Plastics • Good for Color Mixing • Good Shut-off • Faster Screw Recovery - Less Heat Build-up • Possibility of Faster Cycles • 3-Piece Design Improved Designs With Non-Rotating Rings For These Popular Brands: - Cincinnati ACT / Roboshot - Goldstar - JSW - Kawaguchi - Mitsubishi - Nissei - Nissin - Sumitomo - Toshiba - Toyo
OEM Design Advantages: • Good Design for Most General Purpose Materials • Excellent Shut-off • Excellent for Small Precise Shots • OEM Compatible • Rotating Ring Design Where Applicable • All the Best Characteristics of OEM plus custom-designed enhancements to improve overall performance • 3-Piece Design
4-Piece Design Advantages: • Ideal for high abrasion materials • Alloy Tool Steel Nitrided • Carbide Faced • Ceramic Faced • 4-Piece Design

Material Options:

H-13 Tool Steel
A good high strength pre-hardened tool steel which is machined, thru-hardened, and ground dimensionally, then nitride hardened for 72 hours for better wear resistance. H-13 is tough and can handle pressure and torque.

D-2 Tool Steel
A high carbon/high chrome tool steel with good wear resistance, but low on torque strength. D-2 should only be used with 4-piece designs where the stud is manufactured from 4140, H-13 or another high torque steel.

CPM®-9V Tool Steel
A new generation tool steel with a high percentage of vanadium carbide developed for high wear (abrasive) applications. It resists wear from abrasive fillers in resin. (Construction: Carbon 1.8%, Manganese 0.50%, Silicon 0.9%, Chromium 5.25%, Molybdenum 1.3%, Vanadium 9.0%.)

CPM®-420V Tool Steel
Crucible's CPM®-420V is a new stainless tool steel best suited for corrosion resistant applications. CPM®-420V is a higher performance upgrade from CPM®-440V. Corrosion resistance is significantly better than CPM®-440V. Wear resistance is about 25-50% better than CPM®-440V, due to the higher vanadium carbide content of CPM®-420V (9% vanadium vs. 5.5-6% in CPM®-440V).

CPM®-M4 Tool Steel
Crucible's CPM®-M4 is a high vanadium, special purpose, high speed steel exhibiting better wear resistance and toughness than D-2 or CPM®-9V. CPM®-M4 has a hardness rating of 64.0. (Construction: Carbon 1.42%, Chromium 4.0%, Vanadium 4.0%, Tungsten 5.5%, Molybdenum 5.25%.)
