Today, Kahtoola, a leading innovator in outdoor footwear traction, proudly announces the launch of their newest product - NANOspikes™ footwear traction, with tungsten carbide studs under the bottom.

Created specifically with runners in mind, NANOspikes™ offer lightweight, trim, durable and comfortable traction that easily slips over any running shoe; making it possible to jog, sprint, train and walk securely in any weather condition.

"That was on one of our standard KASTOtec AC5 machines, designed for cutting with tungsten carbide-tipped (TCT) blades. We also make a high-performance KPC variant that incorporates two spring-loaded tensioners to guide the tungsten carbide tipped blade on the return side. This suppresses vibration even more, enabling an increase in production of between 15 and 30%, as well as extending blade life further.

Two new members of the family management team visited customers in the UK during December 2013. Stephanie and Jonathan Riegel saw the company's sawing machines and automated industrial warehouses in action in manufacturing and stockholding facilities from Yorkshire down to Birmingham and across to Cambridgeshire. They were accompanied by Ernst Wagner, managing director of Kasto's subsidiary in Milton Keynes.

The couple recently joined the board of Kasto group, along with Nicole and Sönke Krebber, also sixth-generation members, and Ruth Stolzer, wife of sole managing partner Armin Stolzer, who has run the company for the past 25 years. Dieter Heyl is the director in charge of production and Valentin Meier heads design and R&D.

Turnover at the German parent company remained stable at around €100 million, only slightly lower than in 2012 when one very large order for an automated warehouse was taken from the Bavarian uPVC window and door manufacturer Rehau. Business is increasing in many parts of the world, notably Australia, China, Singapore and Egypt. The number of employees is unchanged at 600, 10% of whom are apprentices, reflecting the policy of many German mittelstand manufacturing companies (medium sized, typically privately owned firms).

The group's global storage system deliveries continue to be around twice the value of its sawing machines sales. In the UK, Kasto has delivered six big automated warehouses in the last decade, plus around 20 smaller storage systems.

However, Mr Wagner says Britain needs to avoid falling behind other industrialised nations when it comes to automation. More than 1,400 Kasto automatic storage and retrieval systems for long stock and sheet have been sold around the world, but only a tiny fraction of these are in the UK.

Another indication of the reticence of British firms to embrace automation, he offers, is the slow acceptance of robotics associated with sawing systems. There are hardly any examples in the UK at the moment, whereas in Germany, central Europe and the USA in particular, such systems are used widely for sorting cut pieces, deburring, feeding material to machine tools, and more.

The company's top-end KASTOtec bandsaws are the main driver for growth on the sawing side of the business, with the message that such machines lower cost per cut as a result of their very high performance via tungsten carbide tipped blades. In 2013, however, the issue of minimising vibration has come to the fore, Mr Wagner says.

Vibration reduces tool life and also that of the machine, lowers productivity, raises noise levels and negatively impacts accuracy and surface finish. So now when Mr Wagner is asked by potential customers why they should buy Kasto bandsaws, he points towards the many features of the company's saws that help to minimise vibration, increasing output and reducing customers' ongoing expenditure on tooling.

"Obviously everyone says that they make a rigid machine, but we were able to prove the superiority of Kasto's bandsaws and vibration management recently during comparative trials carried out for a stockholder.

"Using identical feeds and speeds to those on a competitor's bandsaw when cutting 305 mm diameter Inconel, we achieved 55% higher output and three times the tungsten carbide blade life.

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Tungsten Carbide Coatings Technology. According to news reporting originating from Dortmund, Germany, by VerticalNews correspondents, research stated, "The phenomenon of glass-to-mold sticking is a major problem for industrial glass forming processes. Ternary TiAIN coatings attracted considerable industrial interest because of their excellent tribological performance and high oxidation resistance at high temperatures."

Our news editors obtained a quote from the research from Technical University, "Recently, multicomponent CrAlSiN and TiAISIN coatings have been developed in order to gain high hardness and good thermal stability at temperatures exceeding 800 degrees C. In this study, CrAlSiN, TiAlSiN and AlTiN coatings were deposited on tungsten carbide substrates by using a cathodic-arc deposition system with lateral rotating arc cathodes. Titanium, chromium and AlSi (12 at.% of Si) cathodes were used for the deposition of CrAlSiN and TiAlSiN coatings. All the deposited CrAlSiN, TiAlSiN and AlTiN coatings showed a B1-NaCl crystal structure. The deposited CrAlSiN and TiAlSiN coatings exhibited nanocrystalline structure and possessed hardness as high as 35-37 GPa after annealing at 700 degrees C in air. The wettability of the CrAlSiN, TiAlSiN and AlTiN coated tungsten carbides by molten glass at temperatures between 300 degrees C and 700 degrees C in controlled air under 1.6 Pa was measured by using an improved sessile drop method."

According to the news editors, the research concluded: "The CrAlSiN showed a low oxidation rate and a non-wetting characteristic superior to TiAlSiN and AlTiN coatings."

The Penumbra mine is an underground coal mine in South Africa. The company has been struggling with its so-called continuous miners sections. Continuous mining utilizes a Continuous Miner Machine with a large rotating steel drum equipped with tungsten carbide teeth that scrape coal from the seam. Conveyors transport the removed coal from the seam.

Continental Coal Ltd Wednesday said it is still trying to complete a recapitalization that will allow it to settle its convertible notes that mature between November of last year and February of this year, but so far hasn't been able to reach a deal and it warned it may have to appoint administrators.

California Tungsten Carbide Knife and Blade and its global brand Baucor are excited to enter 2014 with state of the art grinding technologies to make industrial tungsten carbide blades and machine knives. California Knife and Blade and Baucor will continue on their commitment in 2014 to manufacturing and supplying highest quality industrial blades, machine knives, and surgical medical blades at affordable prices and within the quickest turnaround time while delivering exceptionally right on time.

A proprietary coatings process, capable of tungsten carbide coating surfaces as flat as 12 millionth of an inch and finishes finer than 1Ra, has been developed by Longevity Coatings, Allentown, PA, for valve components used in oil and gas drilling wellhead equipment.

The finished products—valve sealing tungsten carbide rings and slab gates—are capable of a service life two to three times those produced by competitive coaters and even those of Original Equipment Manufacturers, said Mark Purington, owner and general manager of Longevity.

Wellhead valves are critical components in the drilling process, noted Purington. The wellhead –the structure on the surface of a drilling site— controls the flow of gas or oil during production. Valves in the wellhead are subject to pressures that can reach as high as 20,000 psi. Failure to maintain pressure control at the wellhead could lead to a well blowout.

Purington pointed out that typical wellhead valves have two critical components: the sliding slab gate, which opens and closes to permit passage of fluids, and its mating opposite, the seat or sealing rings. Because of the intense high pressure brought to bear on the valves, the two opposing components cannot employ the types of non-metallic seals often used in industry in similar situations. “Both components are metal, with no intervening sealing materials. Because of this metal-to-metal contact, the surfaces of both the slab and seat must be perfectly flat to ensure there is no possible leakage.”

When the valve components become worn, wellhead operators routinely replace or refurbish them. Longevity can refurbish a slab or seat at a cost as little as one third that of purchasing new components, Purington estimated. “We have all the in-house technology required to take your gate, strip off the old coating, apply a new tungsten carbide coating of high quality tungsten carbide, apply our proprietary flat-finish process—free of any scratches-- and return them in a reasonable time frame.” The final product, he added, is a coating surface as flat as 12 millionth of an inch and a finish finer than 1Ra ---well above the industry standard. Installed, he added, “they will function at or above OEM quality.”

Although Purington sees wellhead service contractors as the primary market for Longevity’s flat-surface process, “We anticipate that some OEMs—wishing to improve still further the service life of their newly manufactured valve components—might want to utilize our services as well.”

Founded in 2005, Longevity Coatings, offers thermal spray coatings services for many parts and equipment components used in the mining and oil/gas drilling industries, including new and rebuilt drive shafts, slurry blenders, fracturing plungers, high pressure pumps, pump plungers and pistons, augers, valves, valve seats, valve tips and valve assembles and impact rings.

The company’s Allentown plant is equipped to apply diffusion bonded metal, ceramic and carbide coatings to virtually any type or size of mining apparatus or accessory, noted Purington. The company’s largest coating handling system can swing parts in excess of 18’ at a diameter of 50". In addition, “our multi-axis computer- directed motion control systems and mechanical multi-spindle setups provide the handling apparatus for processing shafts, sleeves, plungers, valves and numerous other coating applications.”
