New Products 62 Global Plastics rePort 2015 Plasticstoday.com has made cleaning and restart easier and faster than would be possible with a con- ventional head. The Bullet enables quick tooling changes, as the tips are removed from the back while the die comes off from the front of the unit. The absence of fasten- ing hardware eliminates leaking, as does the tapered body and deflector design pioneered by Guill. The extrusion head is suited for both high- and low-volume applications, which are accommodated by the simple, easy replacement of a single component. Various crosshead designs are available, and users can specify the caliber, or max- imum inner diameter, of the die. A vacuum chamber and kit for assem- bly and disassembly are included with the unit. Optional keyed tooling capa- bility offers machine designers and end users quick orientation, so the overall unit design enables faster disassembly, cleaning and restart. Three new recycled polymer grades from Axion Polymers As the market for both recycled and engineering plastics continues to expand, UK-based Axion Polymers (Manches- ter), one of the most advanced plastics recycling facilities in Europe, offers the best of both worlds. The company has announced the launch of three new Axpoly polymer grades recycled from end-of-life automotive and WEEE resources. Development and the intro- duction of the new ABS, PE and PP grades came on the heels of the com- pany's further investment in its refinery plant to increase extrusion capacity and improve melt filtration technology. The newest grade of postconsumer recycled ABS engineering polymer is being marketed under the name Axpoly ABS52 1000, and, according to Axion, offers significant carbon savings of 70% when compared with virgin plastics. It is said to be suitable for molding parts that require durability, longevity, strong puncture strength and good dimensional stability, such as automotive trim com- ponents like car wing mirrors, car bum- pers and related assemblies. The new ABS also boasts good electrical insulation properties, mak- ing it suitable for use in enclosures for domestic products like vacuum clean- ers and kitchen appliances. Custom- ized variations on the standard grade's physical properties requirements, such as flame retardant versions, are also offered by the company. Axion's AxpolyPE51 1090 is a new grade of polyethylene offering carbon savings of 53% versus virgin grades. With properties similar to HDPE, it is suitable for products such as pallets, boxes and shipping containers or other general purpose molded items where durability and good water resistance are required characteristics. The third new grade is a high flexur- al modulus polypropylene called Axpoly PP51 1093, strong enough to withstand an applied top load without flexing. According to Axion, it is ideal for con- struction and civil engineering applica- tions, such as internal support structures for rainwater drainage tanks. Elastomer grade targets consumer, industrial applications Elastocon TPE Technologies Inc. (Roch- ester, IL) has expanded its offerings of thermoplastic elastomers with the intro- duction of a new grade in its general purpose 8000 Series. The newly formu- lated 8078B grade is suited for consumer and industrial applications. Instrument panels, as shown, is one potential appli- cation for the material. The material can be injection molded, extruded or blowmolded, and even overmolded (onto polypro- pylene) for products that call for rubber-like properties (Shore A 82) and a good surface finish. It is avail- able in black pellets in 1,000 lb. quantities and is readily available from Elastocon inventory. Among the features, options and benefits are: Flow properties to enable complex part design; impact resistance; and cold weather and UV stability. Heavily lubricated versions are avail- able to eliminate post-mold lubricant application. Elastocon offers high-performance TPE products across seven product families that include filled, unfilled and oil-free types for medical use. Werth 3D Fiber Probe measures 'around the corner' In an age when manufactured compo- nents are heading into the realm of the micro and even nano scale, quality assur- ance is becoming challenging. Werth Inc. (Old Saybrook, CT), a supplier of dimensional measurement technology instruments and optics, has a new solu- tion. The Werth Fiber Probe (WFP) has opened up the world of microstructures for tactile coordinate metrology. Low contact forces of less than one milli-newton and small probe spheres down to 20 microns in diameter make the 3D WFP suitable for use on pre- cision-engineered components and on sensitive surfaces. This capability previously was avail- able only with straight probe pins, according to the company. The L-probes that are now available can measure undercuts, small side bores and even internal threads. The L-probes have sphere diameters from 0.040 to 0.250 mm. The standard offset between the probe sphere and shaft measures about 1.5 mm; other offsets are also available. With modular control and software integration, the new Werth Fiber Probe can be used in scanning or single-point mode. To take advantage of the precision of the sensor, the company recommends using it with high-precision machines, such as the VideoCheck UA, and with a 3D maximum permissible error down to 300 nanometers.
