Shaping the future

Budweiser announced this week that Belvac’s innovative shaping machinery produced its new Bow-tie can, arguably the most innovative introduction to the market for 30 years.

Bill Speidell, strategic initiatives, Belvac Production Machinery reveals the details of the shaping technology behind the Belvac Vertical Shaper.

The world’s global brands continue to drive increased volume and competitive costs for differentiated metal containers for the beverage, aerosol, and food industries, while the demand for high-speed production machinery to produce cost effective branded containers is also growing. For more than thirty years Belvac has set production standards in the metal container industry worldwide with state of the art can forming machinery.
This increasing drive for demand is met by Belvac through its machinery and complete process solutions capable of producing shaped metal containers at high speeds, with high throughput, and reduced metal consumption. Containers that require vertical sidewall shaping and need to be finished as a can or a bottle require a high-speed, dependable, and proven container shaping solution. The Belvac vertical shaper is a perfect choice. The vertical shaper adds distinction to both cans and bottles by shaping the sidewall of the container up to 200mm from the top edge and within 16mm of the bottom of the container.
The equipment is capable of performing sidewall shaping at up to 1200 containers a minute and accommodate multiple designs on a single set of tooling by simply repositioning the tooling. Other designs can be accommodated by replacing the tooling and in some cases replacing the transfer star wheels to match the container shape.
The vertical shaper is a multi drive system and the number of required drives is dependent on the required number of operations and subsequent number of stages needed to arrive at the desired shaped container. The vertical shaper also demonstrates pocket-to-pocket integrity as the can moves through the necking process.
Cans in feed and transfer with 20 pocket star wheels and are shaped on active turrets with 12 pocket star wheels with a 270 degree working arc. The number of turrets required is a function of the progressions necessary to achieve the desired reductions and expansions.
Can height range is from 121mm up to 254mm and the can body size ranges from 45.2mm to 73mm. Both height and diameter adjustments have quick-change capabilities. The ram assembly has a dual action cam stroke on a vertical main shaft. The push stroke is 129.5mm and the die cam stroke is 101.1mm. The dual stroke design allows for both the depth of the shaping process and the high rotational speeds of the turret.
The modular design of the vertical shaper platform features automatic lubrication, add on waxer, and air assisted discharge track work. Belvac’s stand alone 450QC container waxer is designed to apply mineral oil or hot wax lubricant to the exterior open ends of the container prior to the necking operations.
The modular platform can accommodate up to 20 processing modular bases and additional stages for can inspection modules.
Belvac’s infeed track work is compatible with many systems designed by many manufacturers. The infeed uses a constant velocity vacuum star wheel, which brings containers into the machine at a steady rate. With an optional inspection camera system damaged cans are rejected before entering process turrets.
The vertical shaper is a an integral part of Belvac’s complete process solutions capable of producing shaped metal containers at high speeds, with high throughput, and with reduced metal consumption. Belvac’s full service solutions supports container design and engineering, manufacturing process design and integration, providing a broad range of machinery for container shaping solutions as well as machinery installation and start up.
Belvac not only makes the machinery but also provides a full service support system. Companies don’t need to know how to make a particular can shape, they just need the idea and to call Belvac to create a distinguished and branded can with our full container engineering service.
