MANUFACTURING TECHNOLOGY A system to protect your investment

rose plastic UK, a manufacturer of plastic packaging, has seen an increase in demand for its innovative range of cutting tool packaging.

C

ompanies are recognising the benefits of providing much greater product protection by utilising rose plastic’s wide range of telescopic tubes and boxes for the transportation of goods back to customers.

rose plastic offers a wide range of ‘off the shelf’ packaging solutions,

which are easy to label and quick and simple to package. The packaging can be used by manufacturers as transit packaging to protect their cutting tools. Throughout the process, the cutting tools are given the best possible protection, which ensures less damage in transit and greater customer satisfaction. Companies also have the option to have their plastic packaging personalised with their own corporate colours or company branding to enhance their relationships with customers. One product suitable for cutting tool protection is rose

plastic’s SystemBoard. SystemBoard has been purpose-designed to hold cutting tools of all shapes and sizes rigidly in place during the transportation

process. This helps to reduce damage and offers an organised arrangement of tools, which are securely held in place by the product shank. In addition, SystemBoard provides an invaluable storage solution for tool manufacturers or specialist coating companies. For

cleansing purposes too, tools can be left in the SystemBoard unit, which can withstand temperatures up to 120°C. To complement SystemBoard, rose plastic offers a range of transportation containers, which can be used for the transit packaging of a SystemBoard to and from clients’ production facilities.

Developing innovative metal forming processes

National Machinery LLC’s dedicated engineering division, Met-MAX Innovations, has the total objective of developing innovative metal forming processes. Its most recent technological success has led to three new patents for net forming bearing rollers.

T

he overall technology yields a more complete and stronger part, while also being more cost effective, says National Machinery. This new method for cold forming near net shape metal roller blanks for anti-friction bearings, demonstrates a significant manufacturing improvement over the pre-existing method. Traditionally cold formed rollers are formed in a single die where ‘body sized’ wire is cut off and the material is forced to flow

into the radii of the tool and die cavity. This can imbed cut-off imperfections into the roller’s critical end radii. In order to generate the force needed to fill the corners, the material spills out between the tool and die. This creates a flash band, and it is common that the radii will still not fill uniformly. Extensive grinding is then needed to remove imperfections and finish the end radii adding significantly to the cost of the finished roller. These secondary operations are necessary because of the limitations of the traditional roller bearing forming methods and tooling used. National’s patents for cold formed roller blanks can greatly reduce grinding costs and result in an improved metal grain structure.

The enhanced cold-formed part is produced from tooling that accurately forms the part without flash, and with a continuous grain structure that follows the contours of the end radii, thereby avoiding irregularities in the finished product. The improved grain structure prevents premature bearing failure and extends service life of the roller. This process requires a specialised progressive FORMAX Plus®

Traditional forming method National’s patented forming method machine. These machine

enhancements can be incorporated on any size of new FORMAX Plus cold former. With National’s patented roller bearing forming process, you will achieve stronger, higher quality rollers while reducing expensive secondary procedures. “The technology behind these patents can be

applied to other applications that require extreme symmetry and TIR requirements, including solid/ hollow parts. Improved forming methodology for bearing rollers is just one example of the valuable technology National Machinery LLC can apply to your parts forming needs. The experts at National are ready to help you find better forming solutions for all your challenging parts.”
