“Finding a Better Way” isn’t just a tagline at Rosler Metal Finishing; it’s a mission. A recent preservation line developed by Rosler Germany is no exception.
The creation of a 740-foot-long (225 meters) shot blasting line with straightening equipment is the largest equipment project Rosler Germany has ever undertaken. Commissioned by Meyer Shipyard in Turku, Finland, the state-of-the-art equipment will be used to prepare and finish materials for building cruise ships.

With the revolutionary Gamma G turbine, Rosler has set a new milestone in continual turbine development. It is the most maintenance-friendly turbine in the world, it can be easily installed or retrofitted into a great range of systems, and has a unique price-performance ratio.
Featuring Y-shaped throwing blades made of forged tool steel for high durability. Since both sides of the throwing blades can be utilized, the cost for wear parts can be drastically reduced. Depending on the abrasive used, throwing blades can be used up to three times longer.

High speed and highly controlled, the process of shot peening has many similarities to the aerospace, automotive, and aviation components it is used on. The machines require absolute precision and reproducibility much like the components they are preparing for long life and changing loads.
Shot peening is a special shot blasting process in which spherical blast media is thrown at the surface of metallic work pieces. The impact energy of the pellets “cold forms” the upper layers of the metal similar to hammering and forging processes.

Modern manufacturers are under increasing pressure to minimize production costs without sacrificing product quality or equipment reliability. No one understands this predicament better than high precision die casting manufacturers. Trying to minimize cost associated with scrap and the expensive tooling bodies required for high precision die casting while delivering a consistent product to customers requires balance.
Pace Industries, one of North America’s leading full-service aluminum, zinc, and magnesium die casting manufacturers, found that balance with Rosler. The company needed a cost-effective solution for finishing automotive castings in one of their Mexico facilities. A used through feed tumble belt shot blast machine from Rosler Metal Finishing, USA which had been used in one of Pace’s other facilities was available, but in need of some attention.

Vibratory finishing systems are best known for treating large volumes of mass produced parts. However, thanks to a variety of new, innovative equipment designs, they are increasingly utilized for finishing single work pieces with highly complex geometries.
An excellent example of this new equipment design is Rosler’s model R150/2 DL. A rotary vibrator without an inner dome, this unique finishing process allows for work pieces to be bolted to the vibratory processing bowl.

Shot blasting machines come in all shapes and sizes. Selecting a machine capable of cleaning and descaling complex fabricated components and welded constructions is not a task to pursue alone. Seeking the help of a company with proven expertise in the shot blasting field is always advised.
Designed specifically to clean wide head and base plates, ribs, re-enforcements, and the welds from fabrication, shot blast machines, such as roller conveyor machines, are designed around these types of work pieces.

Machinery and media are nothing in the mass finishing world without the right compound.
A manufactured object can be designed to specifications, but if it doesn’t look and feel finished, it may be rejected. A metal alloy can be structurally perfect, but surface corrosion may make it less presentable. Process water may work well for initial cycles before contaminants wear down its effectiveness over time.
The right compound for a given mass finishing process can solve each of these problems and more.

Tip #3 – Optimum operating conditions
Once a mass finishing process has been established by the selection of machine, media and compound, the system must be constantly monitored and, of course, properly maintained. The good news is, this is quite easy! By following a few simple quality control rules, the process will remain absolutely stable, producing the desired finishing results for many years:

Tip #2 – The need for processing trials
Of course, the selection of the right machine, media and compound can sometimes be a bit intimidating. Not only does a mass finishing user have to choose among a wide variety of machine types and sizes, they must also pick the right media from hundreds of media types, shapes and sizes. And on top of all this Read more about processing trials
Tip #1 – The work pieces are always at the center
The development of any surface finishing solution always revolves around the work pieces. Their material, size, shape and above all, the finishing objectives, determine what type of finishing process must be selected.
The work piece size is especially important. For example, the deburring and edge
