Hasco Hasenclever GmbH + Co. KG has developed the Valve Shot line of hot-runner nozzles, designed for closure caps and the packaging industry.
The needle valve guarantees balanced filling by the simultaneous opening of the valve pins after a certain amount of pressure has built up. The design ensures optimum transmission of the holding pressure, and avoids stringing and drooling of melt from the gates, the firm said.
The needle guidance is close to the gate, with minimal needle stroke, to give long life to the gate. Gate bubble geometry provides good color-change capability, Hasco said.
The front sealing diameter is only 10 millimeters; the body diameter is 16.5mm. Finely scaled nozzle lengths are 80-140mm.
Hasco America is based in Arden, N.C.

Blake improves its downstream designs
Blake Kunststoffproduktionsanlagen GmbH is offering several new pieces of downstream extrusion equipment.
The KT 209 calibration table is fitted with automatically reproducible adjustments for the calibration carrier. Blake said the design allows a range of longitudinal, vertical and lateral adjustments, and accurate changeovers of calibration units. Actuator modules can store up to 60 profile settings.
The RA 306 caterpillar haul-offs feature two separately driven pairs of caterpillars, which are fully synchronized.
Finally, the new SA 410 automatic cutter is designed for cutting thin-wall panels. It employs a rolling, circular knife, instead of the conventional rotary saw blade.
The cutting operation is precise and very fast, according to the company, based in Blieskastel, Germany.

Priamus connectors enhance mold sensors
Priamus System Technologies LLC of Brunswick, Ohio, is responding to demand for a larger number of sensors, and more complex ones, in injection molds.
The firm has introduced a universal system that allows cavity pressure, temperature and machine signals to interface via multiple pin connectors with the attached electronics.
The pin connectors on the side of the mold can be assembled by the user and linked with the electronics by four- or eight-channel cables.
Up to 128 analog signals can be acquired and processed for process monitoring and control.
The multipin connectors for mold-cavity pressure and cavity temperature can be interfaced with quick disconnects that allow the fast, uncomplicated exchange of mold inserts, according to the company.
Air recovery system reduces energy use
Technoplan Engineering SA of Geneva, Switzerland, makes a machine called an air recovery system that enables PET bottle makers to recover air that has residual pressure, cutting energy consumption.
Normally, PET bottle molders exhaust all residual compressed air into the atmosphere. But now, with higher electricity rates, the idea of saving money on compressed air is gaining steam, the company said.
The system is installed between a blow molding machine's exhaust system and that factory's low-pressure air system. It captures and stores nearly 50 percent of the dry, oil-free air at a pressure of 170 pounds per square inch. The equipment then returns air to the plant's low-pressure air system for reuse.
Connell Industries Inc. of Rahway, N.J., is the licensed U.S. distributor of the machinery.
Ball Corp. and Southeastern Container Inc. have used the machine.

Extruder compounds with natural fibers
Berstorff GmbH of Hannover, Germany, has developed a twin-screw extruder for making compounds with natural fibers naturally, with no need for predrying. The machinery maker worked with Hannover University of Applied Sciences.
Berstorff's patented Multi-Process-Elements ensures gentle and cost-effective incorporation of the natural fibers, such as wood flour, flax and hemp.
The company's U.S. unit, Berstorff Corp., is in Florence, Ky.

Reifenhauser creates compact sheet line
Reifenhauser GmbH & Co. KG has developed a compact, standard thermoforming sheet line to make film structures with up to nine layers.
The Mirex Smart sheet line comes in widths of 550-900 millimeters, depending on the number of layers. Throughput capacity ranges from 440-990 pounds an hour, depending on the resin.
The line includes an extruder with a screw diameter of 70mm or 80mm. The coextrusion screw has a 35mm screw.
The sheet die has a flexible lip and external deckling. Another feature, the Reicofeed coextrusion system, has a flexible slide adjustment to give exact thickness of the film layers.
Reifenhauser is based in Troisdorf, Germany. Its U.S. operation, Reifenhauser Inc. is in Ipswich, Mass.

TPEs meet FDA rules for curbing mad cow
Teknor Apex Co. has introduced thermoplastic elastomers that could help curb the spread of bovine spongiform encephalopathy during handling of medical and food items.
Teknor Apex is compounding new Uniprene and Monprene grades that don't contain animal-derived materials, or ADMs, such as beef tallow-based lubricants. The compounds are aimed to comply with European and U.S. Food and Drug Administration directives on preventing spread of the disease.
Medical tubing, syringe tips, toothbrushes, ear plugs and food packaging seals are among the products that could benefit from non-ADMs content elastomers, according to the Pawtucket, R.I., company.
Teknor Apex offers five Uniprene themoplastic vulcanizates without ADMs, in Shore A hardnesses of 45-80. Four of its Monprene TPEs, based on styrenic tri-block copolymers, avoid ADMs and have Shore A hardness values of 38-65.
