TSM amplifier aids recycling process
TSM Control Systems Inc. has released a new down-force amplifier for processing recycled materials.
The TSM technology focuses on combining standard processing requirements, accurate dosing and homogeneous material mixing, with material head pressure which the company calls a critical component when processing regrind and flake.
On its batch blenders, TSM already offers a patented reverse-flight auger, which creates a cramming action on the recycled material. The new down-force amplifier crams materials into the throat of the extruder, eliminating variations in flow because of variations in bulk density, according to the company in Dundalk, Ireland.

Republic shredder handles longer pipe
Attention pipe extruders: Republic Machine Inc. has developed a single-shaft shredder that can take pipe lengths 20 feet long and longer, instead of forcing you to cut pipe into smaller pieces.
The shredder has a flexible size bed that begins at 20 feet and can be extended to 40 feet, or even 60 feet in length.
Republic Machine, based in Louisville, Ky., said the shredder eliminates accidents that can happen when using chain saws or band saws.
Pipe is laid into the bed and fed into a staggered-rotor cutting system by a single-pass, continuous-cut ram. The grinding chamber is easy to access, allowing easy cleanout.
The machine can shred other bulky materials besides pipe.
When we realized the number of chain saws our customers were going through, we knew there was a problem that needed to be solved, said George Sotsky, Republic Machine's president and owner. Chain saws and the danger that comes with them should not be in a modern factory. Republic's pipe shredder solves this issue.

LPKF system checks weld-seam quality
LPKF Laser & Electronics AG's LaserWelding division has added reflection diagnosis to verify successful laser-welded of plastic parts.
LPKF showcased the technology at K 2010 in Germany.
Reflection diagnosis uses the physical effect of light reflection at boundary surfaces. Before welding, there are two boundaries between the two parts. When laser light impinges on these boundaries, a certain amount of light can be reflected, but since areas that have been welded together have no such double boundary, the amount of reflected light is reduced.
Reflection diagnosis can evaluate the quality of a welded seam during the actual welding process.
LPKF is based in Garbsen, Germany. Its U.S. operation is in Tualatin, Ore.

Dukane expands line of ultrasonic welders
Dukane Corp.'s Ultrasonics Division has expanded its line of iQ servo-controlled ultrasonic welders, with new higher-frequency welders.
The welders are designed for welding smaller medical parts such as valves, ports, filters and implant components. They also use Dukane's new Melt Match technology, which the company claims delivers better repeatability, stronger welds, easier validation calibration and lower manufacturing costs compared to standard pneumatic welders.
Dukane is based in St. Charles, Ill.
UNTHA introduces heavy-duty shredders
UNTHA Recyclingtechnik GmbH of Karlstadt, Germany, has introduced the VR series of heavy-duty, single-shaft shredders.
Features include a fail-safe cutting system, a constant material feed and a maintenance-free pushing system.
A new drive allows for high throughput with very low drive power. The gear unit is integrated into the rotor, eliminating the need for shaft stubs, which UNTHA said can cause problems in conventional machines.
The company's U.S. operation, UNTHA America Inc., is based in Newburyport, Mass.

B&H offers analysis package for extruders
B&H Tool Co., which makes extrusion tooling in San Marcos, Calif., has introduced a technical and process analysis package for extruders of thermoplastics and fluoropolymers.
The engineering service package quickly identifies the causes of difficulties related to equipment surging, dimensional variation, material degradation and appearance problems. B&H Tool tailors it to needs of individual extruders in North America.
The product gives a detailed simulation of a proposed process change, and models a process that is being planned.
The package includes a detailed evaluation of operations, material handling upstream and downstream of the extruder, the equipment, screw geometry, dies, packaging and all process metrics. Special attention is given to temperature profiles at critical points, and how they impact both equipment and material performance over the short and long term.
