Last Call for Papers for Molding 2015 Conference

By: Matthew H. Naitove 7. October 2014

Don’t be bashful! Share your concerns, triumphs, and challenges with your peers at this annual conference aimed at injection molders only. You’ll hear technical presentations from suppliers of machinery, molds, materials, etc., but some of the most intriguing talks each year come from molders themselves. They have discussed their progress in sustainability, challenges in finding qualified workers, issues about competing domestically and internationally, and their assessment of what it takes to succeed in markets like medical, electronics, and so on.

 

Molding 2015 will be held next June 16-18 in Rosemont, Ill., co-located with the Amerimold show and conference, also an event sponsored by Gardner Business Media.

 

At Molding 2015, there will be sessions on these topics:

 •  Emerging technologies.

 •  Sustainable manufacturing.

 •  Medical molding.

 •  Molding integrated electronic components.

 •  Adding value: Automation, Assembly, Packaging, LSR Molding.

 

If you have a story to tell or an issue to raise with other molders, send in a brief abstract before the deadline – Oct. 17. For more information on the conference, and instructions on submitting an abstract, visit this site and click on “Online Call for Papers.”

The Customer Buys the Machine, You Mold the Parts

By: Matthew H. Naitove 1. October 2014

I’ve heard of custom molders locating a satellite operation inside a customer’s facility, but a recent visit to Currier Plastics in upstate Auburn, N.Y., exposed me to the inverse of that arrangement. On both the injection and blow molding sides of its business, Currier is operating some customer-owned machines in its plant. The reasons for doing so differed in each case.

 

In extrusion blow molding, Currier runs a large Automa machine making three sizes of HDPE detergent bottles. According to Steve Valentino, blow molding plant manager, the basic machine cost $1 million and required another $300,000 to $400,000 in hardware and software modifications for product-quality purposes and to allow quicker mold changes. Because the raw material accounted for 70% of the piece price, Currier told the customer that the job would not be profitable if Currier had to pay for the machine and upgrades. So the customer bought the machine and pays Currier to operate it, but at a much lower machine-time rate than usual. (The machine is pictured here receiving attention from Mary Stotler, Currier’s first female blow molding technician.)

 

In injection molding, Currier had been custom molding acetal electrical parts an OEM that subsequently acquired a business with in-house molding capacity. The OEM came to the conclusion that Currier could mold the parts more efficiently than the acquired captive operation. So the OEM moved eight Engel presses to Currier. Five of them are now molding acetal cable-connector insulators; the other three are currently idle, awaiting new program approvals. Again, both parties save money, so the arrangement profits both, according to Sriraj Patel, injection molding project engineering manager and toolroom manager.

More Details On The Big Area Additive Manufacturing (BAAM) Project

By: Lilli Manolis Sherman 27. September 2014

 

As I discussed in an earlier blog this week, the launch of Cincinnati Inc.’s prototype Big Area Additive Manufacturing Machine (BAAM) made a big splash at the recent IMTS show in Chicago, and further development of what is already an impressive machine is underway.

 

A couple more interesting tidbits about BAAM were passed onto me by my colleague Jim Callari. One is that Dri-Air Industries furnished the dryers for the carbon fiber reinforced ABS that was used for the Strati car project that was produced during IMTS. The other is that a well-known authority in plastics processing and machinery  designed the screw for the project. The original screw used was generating 10 lb/hr but the new design from this pro boosted BAAM’s output to 35-40 lb/hr, as noted in the earlier blog. This pro has also signed up to design and build new extruders for this evolving project.

 

As reported previously, BAAM resulted from the formation of the company’s partnership earlier this year with Oak Ridge National Laboratory (ORNL) to develop a large-scale additive manufacturing system. The partners aim: to introduce significant new capabilities to the U.S. machine tool sector which supplies manufacturing technology to automotive, aerospace, appliance, and robotic industries.

 

The prototype machine uses the chassis and drives of Cincinnati Inc.’s gantry-style laser cutting systems at the base, and incorporates a high-speed cutting tool, pellet feed mechanism, and control software. Cincinnati Inc.’s market development manager Rick Neff explained to me how the company participated with Local Motors, Sabic and ORNL to take on the challenge to 3D print a car during the IMTS trade show.

 

Printing started on Sunday morning at 7 am, and by 6 am Tuesday, they had printed the main structure of the car including the frame, seats, cockpit, hood and tail in one 1000-lb piece. The rough part was then taken to a Thermwood Router where the surfaces that needed to be accurately machined smooth were routed smooth.

 

On Wednesday through Saturday morning, the Local Motors crew attached a drive train, suspension, steering wheel, instruments, brakes and some trim to complete the car. The car, named Strati (Italian for layers), uses a drive train from Renault that is employed in the European Twizy City Car. “Right on schedule at 9 am Saturday, we fired up the Strati and drove it out of the show…the reaction from the crowd and the press was overwhelming,” says Neff.

 

Here is some key information Neff provided about BAAM:

 

• The machine extrudes hot thermoplastic to build parts layer-by-layer, similar to an FDM machine.

• BAAM’s extrusion rates are very high—in the neighborhood of 35 lb/hr, which is reportedly hundreds of times faster than typical rapid prototyping 3D printers.

• The material for Strati is ABS with carbon fiber reinforcement formulated right into the plastic. Carbon fiber reinforced ABS is readily available for about $7/lb.

• The layer thickness is 0.160”.

• The build envelope on the prototype BAAM is 2m x 4m x 0.87m.

• The extruder can use quite a variety of thermoplastics and fiber reinforced thermoplastics. Neff says they have used ABS, PPS, PEKK, and PEI. Carbon fiber and glass fiber reinforcements have been used to improve strength and thermal stability of the parts.

 

Although a production version of BAAM is not yet ready for delivery, Neff confirms that the company is considering selling a very few alpha level machines to laboratories or companies who would like to do some basic research on the technology right now. He says, they are also willing to take orders for beta level and production machines that will be available in 2015 for customers who want to be the first in their industry to be using BAAM.

New Initiative Aims At Workforce Development

By: James Callari 26. September 2014

The Society of the Plastics Industry (SPI) and the Society of Manufacturing Engineers (SME) Tooling U have announced the launch of a new online training program aimed at closing the manufacturing skills gap in the plastics industry. Administered by Tooling U-SME, PlasticsU will serve the plastics industry by providing formal online training tailored specifically for the industry’s challenges and needs. Tooling U-SME is considered a leader in providing workforce development and training to the manufacturing industry,

 

“Our industry has some of the best and brightest workers, operating top-of-the-line equipment and technology,” said Bill Carteaux, SPI's president and CEO. “Unfortunately, many of the technological advancements made recently are being held back by a growing manufacturing skills gap, which is why SPI partnered with Tooling U-SME to launch PlasticsU.”

 

He adds, “The plastics industry will not realize its full capacity for growth and production unless companies take an active approach to workforce development. PlasticsU offers these companies flexibility and convenience to make this process easy.”

 

As recently as 2013, a vast majority of U.S. manufacturing companies reported being challenged by a moderate shortage of qualified workers for skilled production, as reported by SME. Volume alone is no longer the sole solution to increased productivity. Highly technical and specialized skills are required not only to meet increased demand, but to maintain growth into the future.

 

“By instituting a training program, companies can ensure they remain competitive today and into the future,” said Jeannine Kunz, managing director of SME’s Workforce and Education. “Creating a well-trained workforce can help improve quality, cycle time, communications, reliability and safety, while reducing costs and downtime/rework.”

 

Because SPI represents and supports such a wide range of the companies throughout the entire plastics industry, it partnered with Tooling U-SME to develop PlasticsU and provide a customized selection of courses and programs for areas specific to as many stakeholders as possible. With levels ranging from a basic introduction to the most advanced studies, courses include Interpreting Blueprints; Creating a Milling Program; Principles of Injection Molding; Measuring System Analysis; Rigging Inspection and Safety; and CNC Controls: GE Fanuc, Haas and Mazak.

In another somewhat related development, DME Company, a leading supplier of hot runners, mold bases and a variety of other mold components based in Madison Heights, Mich.,  has awarded a $1,000 DME Plastics University scholarship to a senior student at the University of Wisconsin-Platteville. Teng Yang (photo below), who hails from Oshkosh, Wis, received the scholarship for the fall 2014 semester at UW-Platteville. It is the second time Yang has been named a recipient of the scholarship. He is the second student to be awarded the DME Plastics University Scholarship twice since the program's inception.

 

Each year since 2008, DME has offered this scholarship program to help finance, encourage and support the future of qualified students who have interest and potential in moldmaking, plastics and related career fields.

 

“DME is committed to advancing training and education within the plastics industry by continuing to support the DME Plastics University Scholarship Program,” said Dean Froney, DME v.p. and GM. “As one of the preeminent leaders in the industry, it’s both our obligation and in our best interest to help develop and groom tomorrow’s moldmaking and plastics industry experts.”

 

o qualify for the scholarship, students must be enrolled in a plastics program at any accredited trade school or university with a two-year certificate, two-year associate or four-year bachelor’s degree program. Applicants who are enrolled in related coursework are also considered if they demonstrate a strong academic emphasis and interest in plastics.

 

Along with an application, students are required to submit a transcript, personal statement and recommendations for review. The DME Plastics University Scholarship Program selection committee considers a variety of factors including academic achievement, interest in the field and personal qualities to determine the winners.

 

DME and other major manufacturers continue an attempt to combat the trend of students shying away from manufacturing disciplines. With an aging population of skilled workers, the plastics industry is facing a major human resources challenge. The scholarship program is just one of the ways DME is taking action to support the ambition of college students who have shown interest in the plastics industry.

 

The company also offers grants and scholarships to its customers for continuing education, an extension of the popular DME Plastics University on that was created to aid new plastics industry students and professionals.

 

DME scholarship applications for the spring 2015 semester are available here.
