The Milling and Mixing Market
For manufacturers of milling and mixing equipment, 2009 was challenging, but there were some signs of improvement near the end of the year.
By David Savastano, Editor
There can be little doubt that the recession took its toll on milling and mixer manufacturers, as capital expenditures curtailed sharply in 2009. However, equipment manufacturers noted that there was somewhat of a pick-up at the end of 2009.
“Sales toward the ink industry sharply dropped, starting September 2008, and stayed about 50 percent of the normal volumes until about September 2009,” said René Eisenring, GD sales manager for Buhler Inc. USA. “I am told by the many ink companies that the packaging ink sector and the digital ink sector are showing some notable growth.”
“The recent recession, failing newspapers and wholesale consolidations of ink producers has greatly conspired to shift the paradigm,” said Jerry Tippett, president of Schold Machine Corp. “‘Cap and Trade’ and increased ‘green’ mandates will further challenge the industry if allowed to pass.”
“The recession made for a year of softer sales in all areas, not just the ink industry,” said Bob Schilling, sales manager for Union Process.
“The recession has certainly affected the need for processing equipment in the ink industry,” said Cathy Strahan, marketing director, Myers Engineering, Inc. “We have seen little activity for mixing or milling equipment needs.”
Korkmaz Oz, sales engineer at Draiswerke, noted that smaller ink manufacturers showed more interest in equipment during the past year.
“In general, equipment sales into the ink industry in the U.S. had been flat during 2009,” said Mr. Oz. “However, the interest for new equipment from small producers in the U.S. as well as other ink manufacturers around the globe had been better than our expectations. Especially in the U.S., it was a pleasure to see small producers grow and invest in larger equipment. Having been with these small companies right from their start helped both parties along the way.”
“The recession sure took a toll on new equipment purchases,” said Stewart Rissley, national sales manager – Premier Mill Operation for SPX Process Equipment. “However, with the Premier Mill horizontal media mills’ flexibility, we’re able to work with many companies to optimize and maximize their current Premier Mill media mills, resulting in improving quality, throughput and reducing maintenance with a few bolt-on improvements.”
“The recession effected everyone in the industry,” said George Murphy, vice president sales and marketing for Hockmeyer Equipment. “We continued our pursuit of all markets. The ink industry continued as one of our target industries with the our Immersion Mill. Due to our introduction of two new mill series, the HCPS and HCPN, we have seen a increase in interest and business from all areas of the ink industry, including the graphic arts industry.”
Signs of Improvement Heading into 2010
The latter part of 2009 brought some good news to milling and mixing equipment suppliers. For example, Mr. Rissley reported that equipment usage was on the upswing at the end of 2009.
“During 2009, we noticed that equipment utilization was reduced significantly, and our indicators are showing utilization is increasing in Q4 2009 and into 2010,” Mr. Rissley said.
“We noticed an improvement starting in September 2009, with very positive numbers for November and December 2009,” Mr. Eisenring said. “Recovery will still be a long road and it may take years to be back where we were economically before the market crashed.”
“We have seen slight pick up in the ink industry towards the end of 2009 and the beginning of 2010,” Mr. Schilling said.
“There is activity whereby the planners and engineers, still employed, are gathering meaningful data and costs on more efficient processing for the future,” Mr. Tippett said. “However, little is currently being done due to the economic conditions, including a sagging demand for various publications. The late 2009 ‘upturn’ can mostly be attributed to the seasonal demand. Should half of the conceptual projects we are engaged in come to pass, then the new year will be exciting.”
“At the end of 2009, there was a slight increase in conversation and processing questions in regards to mixing improvements,” Ms. Strahan said. “We have not seen any significant movement that would allow us to forecast major projects.”
“We had seen some signs of increased capacity,” Mr. Oz said. “However, we also realize this can be met with their existing equipment without making investment into new equipment.”
When they are looking for new processing equipment, ink manufacturers are focusing on efficiency.
Mr. Rissley said that ink manufacturers are looking for optimized performance with flexibility to change to current and upcoming production and product requirements. Mr. Eisenring said that quality, low operational cost, fast ROI, honesty and quick service are important factors.
“There is renewed interest in increasing efficiencies relative to batch sizes,” Mr. Tippett said. “Bigger is not always better, when considering production infrastructure, flexibility of manufacturing, inventory and customer demand variables.”
“Improvements are always about saving time and improving output,” Ms. Strahan noted. “More efficient mixing or milling that produces a better product faster will equate to higher earnings. Who wouldn’t be asking for that? Being green is always a focus, but those features are usually adjacent to our part of the process.”
Among some of the new mills and mixers products that have been introduced recently are, clockwise from top, Premier Mill’s SuperFLX Media Mill, Union Process’Q-03, Buhler’s next generation Viva three roller mill and Draiswerke’s DCP Megaflow mill.
“The ink industry is like any other. They are all looking for a mill that offers the best return for the investment, the best in product quality and consistency, the least down time and the most versatile, with low operating cost,” Mr. Murphy said. “The bottom line is ink companies want a mill that can do the job that adds to the bottom line, not take from it.”
“Service, service, service… being with the customers every step of the way and helping them get the most out of their equipment benefited us in 2009,” Mr. Oz said. “Draiswerke hired new people to its service network to better respond the customer’s needs.”
Recent Product Introductions
To meet the needs of customers, milling and mixing manufacturers have launched a variety of new products.
Mr. Schilling noted that Union Process’ most recent introduction is the Mini Laboratory Circulation Mill,the Q-03. “This mill offers customers the advantage of performing lab tests with a circulation mill using smaller samples,” Mr. Schilling said. “They have the ability to achieve a narrow particle size distribution, good temperature control and the ability to make formulations adjustments on the fly.”
Mr. Rissley said that Premier Mill launched its Super FLX media mill.
“Our New SuperFLX media mills defines flexibility in milling technologies for today’s current tough requirements and future milling demands,” Mr. Rissley said. “This design allows for simple bolt-on upgrades to optimize and maximize the mill’s performance. Our PSM Basket Mill works with some small batch and speciality ink requirements. The PSM allows up to 99 percent yield and quick and minimal cleaning requirements allowing for quick changeovers and reduced cleaning cost.”
“We further improved the world-famous Drais DCP Technology for use with high viscosity inks,” Mr. Oz said. “The Drais MegaFlow Mill, designed with superior centrifugal separation of the grinding media from the product and precise product temperature control, is the answer for most ink manufacturing processes.”
“Our patented Pre-Mixers, Mills and Press-Outs specifically for ‘heavy base ink’ production as well as Vacuum Deaeration units are popular,” Mr. Tippett noted. “These units either increase production, improve flexibility or eliminate secondary processing steps.”
Mr. Eisenring said that Buhler introduced the new TRIAS three roller mill.
“That is our next generation ‘Viva’ mill,” Mr. Eisenring noted. “The new Trias brings powerful roll pressure that generates a linear loads from virtually 0 N/mm to more than 80 N/mm. Compared to conventional three-roll mills, this range is significantly wider, both at the lower and upper limits. Products that previously manufactured in gap operation can now be produced in low pressure mode (5–10 N/mm). This ensures reproducible, defined production conditions. In contrast, the high linear load up to 80 N/mm makes it possible to efficiently manufacture products that are difficult to disperse. In addition the rolls can be exchanged very quickly, because the complete roll package can be removed by releasing just a few elements,and can be replaced with a new roller package, to guarantee the mill up and running again the same day.”
Mr. Murphy said that Hockmeyer Equipment made two recent introductions which he said not only benefits the ink manufacturer but all industries processing products on a media mill, and was awarded its fourth and fifth U.S. patents on continuing advances in immersion mill technology. Patent number 7,175,118 covers the use of a rotating auger in the feed tube chamber of the mill, while Patent Number 7,559,493 covers the deterrence of wear at a bearing construct in a basket media mill. The close fitting, pitch matched auger effectively grabs and propels high viscosity feedstock thru the feed chamber down into the grind chamber and increases the flow through a large separation device.
“The Hockmeyer Immersion Mill is the most versatile with the capability of running products from 200cps up to 500,000cps, utilizing media sizes from 1/4" down to 0.2mm in size and experimenting with good success with 0.1mm in size with no screen clogging,” Mr. Murphy said. “We can outperform a roller mill in the upper end of our viscosity range. I know of no other media mill that can do this.”
Service as an Important Differentiator
As Mr. Oz noted, service is a key aspect for equipment purchasers. “Service is the face of your company,” Mr. Oz said. “To be with the customer at the start-up and every time they have a problem in their process, whether or not it is equipment related, gets you ahead of the game. Building trust and increasing comfort level of the customer are the keys for getting future business.”
“Service is important,” Mr. Rissley noted. “Maintenance staffs and preventative maintenance schedules seem to be the first things cut when times get tough. We are set up with service around the world and can advise and help over the phone or via email and web ex at a moment’s notice.”
“Service is always important,” Mr. Tippett said. “We see a shift somewhat back to ‘in house,’ repair and maintenance. We sense this shift due to healthy parts orders and technical repair inquiries.”
“Local service and spare parts are a very big factor, otherwise we would see many more foreign mill manufactures already here,” Mr. Eisenring observed. “Equipment can be copied easily, but service and support, that is an other matter.”
“Service is always important,” Mr. Schilling said. “Customers want a manufacturer to maintain the reliability of their equipment. I think everyone understands that humans are not perfect and humans make mistakes, but customersexpect a manufacturer to remedy those mistakes when the need arises.”
“Our customers are keenly aware that the near 70 years of experience Myers offers will provide them with the confidence they need for service in the future as their equipment needs maintenance or upgrades,” Ms. Strahan said. “For mixing equipment, service is simply a must.”
“Service and customer support is a very important component in any sale, whether you’re selling a salt and pepper shaker or a technically advanced state-of-the-art media mill,” Mr. Murphy said. “Our service and support is who we are. Without it, what are we selling? Service and support is how we stay close to our customer’s business. It leads the way, telling us what we need to provide to support their success which, in turn, drives our R&D efforts to provide for their ongoing success. So yes, service is paramount for both our customer and us.”
Printed Electronics USA 09 Covers Gamut of PE
By David Savastano, Editor
Printed electronics (PE) continues to offer opportunities for new technologies and applications, and it is receiving more notice as companies large and small develop new products. Printed Electronics USA 09, co-located with Photovoltaics USA 09, from Dec. 1-4 at the San Jose Convention Center in San Jose, CA, offered insights into the innovations from end users, materials and equipment manufacturers and university researchers.
Printed Electronics USA 09 fared very well, as more than 900 attendees came to the conference, a gain of more than 20 percent from the previous year. IDTechEx, the conference’s organizer, ensured that the wide gamut of topics were covered, from photovoltaics (PV) and displays to eReaders and printed sensors and much more.
“We’re delighted,” Dr. Peter Harrop, IDTechEx’s chairman, said after the conference concluded. “The conference was excellent. There was a tremendous swing to end users who attended. We saw major companies like General Dynamics, the U.S. military, and the big consumer product groups as well as major chemical companies like Hitachi and BASF, and companies like Adidas. We also saw a number of breakthroughs in technology.”
The opening session began with a series of keynote talks centered on the state of the industry and potential applications. Raghu Das, CEO of IDTechEx, Inc., spoke on "Printed Electronics Products: Who Wants What, When, Why and How Much." Das discussed routes to profitability, opportunities in the value chain, as well as a 10-year forecast.
Mr. Das cited 2010 sales of $900 million for the OLED market, $400 million for PV, $120 million for sensors and $100 million for eReaders, with high hopes for the future.
“By 2020, we envision OLED to be a $19 billion market, PV $17 billion, and e-paper $6 billion,” Mr. Das said. “The key drivers are flexibility, which allows electronics to go in places whee it couldn’t go before while using less expensive substrates.”
Dr. Kenneth McGuire, principal scientist, Procter & Gamble, spoke about "Consumer Electronics Applications." McGuire noted that while Procter & Gamble sees great value in products which are enabled by printed electronics, there still exist gaps in many areas making commercialization difficult for much of its business.
“PE could help us stand out on the shelf,” Dr. McGuire said. “For us, value is not about cost. What we need is to create ubiquitous products that everyone wants to buy.”
Dr. Markus Strecker, wearable sports electronics engineering director, Adidas, USA, analyzed "The State of Smart Fabrics and Opportunities for Printed Electronics," an overview of smart fabric applications as well as potential needs.
