Conover, NC—PSI-Polymer Systems Inc. has announced it has completed its move to an all-new facility in Conover, North Carolina. The new building is approximately 8 miles from the company’s former location in Hickory and features 45,000ft² of floor space, three times more space than PSI had in their old location.
PSI plans to use the additional space to expand its service offerings to customers and will also stock additional spare parts inventory. In addition, PSI is adding numerous new machine tools to enhance the company’s manufacturing and repair capabilities.
Extruders and pelletizers running recycled materials can greatly benefit from the use of the continuous backflush screen changer (CSC/BF) from PSI-Polymer Systems Inc. The CSC/BF provides maximum melt filtration capabilities, separating the impurities out of the material and allowing processors to continue running with no downtime.
Because of the unique design of the CSC/BF, it provides as much as 25x the life span of the screen pack filters compared to standard styles of screen changers. This allows processors to confidently process recycled materials without fear of clogging the system.
Hickory, NC—PSI-Polymer Systems Inc. has introduced a new line of extrusion gear pumps specifically designed for processing cross-linked polyethylene (PEX).
PEX is a commonly used material for producing plumbing pipe and tubing. It offers advantages over more traditional piping materials as it can process hot and cold water, and withstand high pressures. However, because of the cross-linking process, PEX cannot be re-melted and the material typically cures in less than 5 minutes.
Hickory, NC—PSI-Polymer Systems Inc. has announced it has implemented a new repair & rebuild service program for gear pumps, screen changers, and static mixers for extrusion applications. This new program emphasizes service and repair of non-PSI brands of equipment. Turnaround times are often 24 hours or less.
The new repair center, located in-house at PSI’s headquarters in Hickory, NC, features all the equipment necessary to perform repairs and rebuilds including burn-out ovens, lathes and milling machines, glass bead machines, hydraulic presses and welding machinery. PSI also maintains a large inventory of spare parts to fit its equipment as well as other leading brands.
Hickory, NC—PSI-Polymer Systems Inc. has introduced a new line of hydraulic slide plate screen changers specifically designed for polymer filtration in twin screw extruder applications.
The new “HSC Oval” series of hydraulic screen changers feature oval-shaped screens and “8” pattern inlet bores to match twin screw extruder barrel configurations. This eliminates divergent flow transitions and stagnant flow areas that are typical with competitive models that use circular bore designs fitted with 8-0 adapters. The HSC Oval series also allows the extruder screw to be extended into close proximity of the screens and breaker plates, and for added convenience the screw may be removed through the screen changer without dismounting.
Hickory, NC—PSI-Polymer Systems Inc. has been awarded U.S. Patent No. 7,147,774 B2 by inventor Bart Jones for its “Pressure Activated All Metal Lifetime Seal” utilized in its Model HSC Hydraulic Slide Plate and Model MSC Manual Screen Changers.
The all metal seal, which comes standard on HSC screen changers and is optional on the MSC screen changers, uses six precision cut segments to provide sealing of the slide plate at temperatures from room temperature up to 700°F and 10,000 psi head pressure. The patented seal eliminates dead areas associated with other types of all-metal seals and eliminates the need for Teflon rings, which fail at elevated temperatures and deteriorate over time, and require replacement in all applications.
Hickory, NC—At NPE 2006, PSI-Polymer Systems Inc. will introduce several new products for the plastics extrusion industry. These products include:
Hickory, NC—A new high pressure gear pump (HGP) has been introduced by PSI-Polymer Systems Inc. This product is ideal for the most demanding extrusion processes. It is designed to process highly viscous, filled materials and can operate at pressures up to 10,000 PSI and temperatures up to 600°F.
The HGP accurately meters the polymer and pressure from the extruder to the die, providing consistent output, precise gauge control, and a higher quality end product. It is mounted between the extruder and the die head to eliminate any process variations initiating in the extruder.
HICKORY, NC—PSI-Polymer Systems Inc. has introduced a new Continuous Backflush Screen Changer (CSC/BF), designed for highly reliable polymer filtration in a wide variety of extrusion applications.
Featuring a unique design, the new CSC/BF allows for increased filtration screen life, by at least 25 times over typical continuous screen changer designs. Increased screen life means less frequent screen changes due to clogging from contaminants in the plastic melt. This translates into much less downtime, meaning higher reliability and higher productivity for processors. Another key benefit of the CSC/BF is that it reduces the back pressure on the extruder to a much lower pressure, thereby allowing for increased output - as much as a 50% increase on some materials and processes.

HICKORY, NC—PSI-Polymer Systems Inc. has introduced a new product, an 8" hydraulic screen changer for polymer filtration on large extrusion applications.
Named the HSC-80, this new product has been designed and is currently being manufactured in the U.S. at PSI's headquarters in Hickory, NC, with shipments to begin in April 2004. It has been designed for use on larger compounding lines and because of its large filtration area, it is ideal for use on smaller extruders (4 ½" or 6") that are running high levels of recycled material.
