Silverson Machines Receives Multiple Awards

Recognized for excellence in business, exports and training

CHESHAM, U.K. (November 12, 2019) — Silverson Machines Ltd., a manufacturer of industrial, high-shear mixing equipment, recently received several accolades for contributions to its local community and beyond. The company was recognized for its apprentice training program and excellence in manufacturing, and also achieved finalist status for a national manufacturing award for its export practices. This trifecta of recognition testifies to Silverson’s high standards in its business dealings and the company’s commitment to training future generations of highly skilled engineers.

Silverson received two local awards; the first for its leadership in business and entrepreneurial vision, the second for its apprenticeship program. While Silverson previously achieved finalist status for its apprentice program, this is the first year the company was honored with the prize. Silverson started its apprentice program in 2014. The traditional five-year indentured apprenticeship in mechanical engineering combines practical training with study for a recognized qualification. The first apprentice to complete the program now works on the shop floor as a fully-qualified engineer in one of the specialized departments at Silverson. Two more apprentices from the program’s second year will complete their course of study and training early next year.

Silverson also was recognized for its achievements in international trade through the Manufacturing MX Awards, the U.K.’s largest and most rigorous industry awards program. This award recognizes a company, which through its export business, has been able to: increase international sales; demonstrate a commitment to expanding international business; and demonstrate the value and contribution of exporting to the future of the business. Nearly 50 top manufacturers in the United Kingdom made it to the finals, vying for the top award of Manufacturer of the Year. The awards presentation is scheduled for November 14, during Digital Manufacturing Week, which celebrates the best of British industry.

Harold Rothman, CEO, Silverson Machines said, “We’re grateful for the recognition for our business practices and our commitment to our local community. First off, the future of any business lies within the next generation.  We intend to continue and hopefully expand our internship and training opportunities for the best and brightest young people who possess the initiative, drive, curiosity and passion for learning that will help them succeed. In terms of our business practices, we hold ourselves to the highest standards of quality and integrity. Our greatest achievement lies in helping our customers attain their goals.”

How to Disperse Fumed Silica with Silverson Machines

Fumed Silica, well known by its trade names Aerosil® and Cab-o-sil®, is very difficult to disperse for a number of reasons. The powder is extremely low density so tends to float on the surface of the liquid base.

Conventional mixers and stirrers aren’t capable of rapidly incorporating the powder and activating its thickening effect so formulations often contain excessive amounts of Fumed Silica to compensate for this.

Due to the fineness of the powder, dusting can also cause problems. The high shear action of a Silverson Machines, Inc. mixer can solve these problems while also improving your product quality, stability and mixing times.

Silverson Lab Mixers- Graphene Research

Silverson Laboratory Mixers Are At The Forefront Of Graphene Research

A leading university recently placed an order for (13) Silverson Laboratory mixers for their new graphene center. The new facility will help accelerate graphene commercialization.  Graphene is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure one million times thinner than a sheet of paper. It is the strongest known material – 200 times stronger than steel, it is highly conductive of both heat and electricity, and yet lightweight and flexible, making it a desirable material for use in many industries including aerospace, engineering, digital electronics, bio-medicines, transport and energy.

Graphene was first isolated from graphite in 2004 using a sticky tape method – removing flakes from a piece of graphite using a piece of sticky tape. By repeatedly separating the graphite fragments, flakes just one atom thick were created. Although this method is still used in laboratories it cannot be replicated on a larger scale, and research into ways of isolating graphene in sufficient amounts to be commercially viable has been ongoing for some years. A process called exfoliation, which is the high shear mixing of graphite in a suitable solvent, has been proven to isolate small but significant amounts of graphene.

Silverson mixers have the high shear necessary to reduce the graphite down to usable defect-free graphene, and the equipment has been used by many of the leading researchers due to the ease of scale up from the laboratory mixers to larger production models. Subsequently Silverson have already sold mixers to research establishments all over the world for this application.  The Model L5M-A Sealed Unit, L5M-A standard unit, and the Model AX5, each with a full range of work-heads, is useful equipment for this research work.
