Hatebur has developed and tailored its HOTmatic AMP 20N, a machine that is specifically designed for the manufacturing of forged cam lobes.

With this machine, the company aims to improve the efficiency and productivity of suppliers in the automotive industry.
“Almost all of the world’s forged cam lobes are produced on Hatebur machines,” states Thomas Christoffel, CEO of Hatebur. “With the development of the HOTmatic AMP 20N, we are reacting to new trends in the industry. We want to make our customers even more productive and strengthen our market leadership.
“The trend is heading towards thinner cam lobes in order to support the lightweight construction of engines,” he continues. “That is why the R&D division of Hatebur has started early with fundamental research on cam lobes featuring a thickness of 8 mm instead of 12 mm. The thinner cam lobes impose higher demands on the forming machine – in particular with regard to the shearing quality, pressing force and part transfer.
The HOTmatic AMP 20N offers a total press load of 1500 kN; the machine body has been reinforced to guarantee the necessary stability.
In three forming stations – and with a maximum of 200 strokes per minute – the AMP 20N produces cam lobes with an outer diameter of up to 48 mm out of raw parts with 24 to 217 g.
The up to 6 m long, almost 1200°C hot bars are brought exactly into position via four feeder rollers, powered by servo drives.

Two all-electric tube-bending machines from Unison are helping Ultibend Industries to increase the manufacturing productivity of stainless steel tube fittings for food and beverage processing systems at its manufacturing facility in Wellington, New Zealand.

Ultibend purchased two customised tube-bending machines to suit its proprietary manufacturing process; the machines from Unison automate the bending of tube-fitting shapes such as elbows and U-bends, in sizes from 25 to 100 mm in diameter. Manufacturing operations have demonstrated that the Unison tube-bending machines have significantly boosted Ultibend’s manufacturing speed compared with its previous hydraulic bending machines.
“We knew of Unison as we have had dealings with them in the past,” says Ultibend director Linc Turley. “We like that being software engineers, Unison can take our ideas and issues, and come up with a tailored solution in the form of a customer-specific machine. They’re also an ethical company whose values align with our own. This has been proved in our dealings with them, and the excellent support and prompt response to any issues we have.”
Describing some of the key advantages of Unison’s machines, he adds: “The Unison solution has been invaluable as opposed to our old hydraulic system; the all-electric servo-driven machines give us greater control over bend parameters and increased accuracy. All the data is captured and automatically adjusted to the correct position during set up as opposed to manual adjustments. This gives us the ability to put lower skilled operators on these machines, as doing set ups and making adjustments is more straightforward.”

For over five years, Wilson Tool has offered free lean manufacturing training events to customers.

These events detail the company’s own journey and provide lean solutions that can be applied at customer facilities. The training is also a way for manufacturers to share ideas, success stories and learning experiences, while picking up tips from others.
Wilson’s lean seminars are a full-day event split into two different sections. The first focuses on basic principles like 5S, the seven deadly wastes and one-piece flow. Wilson’s training explores the underlying theories driving lean, coupled with experiments to apply them.
The second half of the day uncovers Wilson Tool’s lean journey and showcases product innovations that have come out of it. Participants go on a shop tour, taking a look at how the company has applied lean principles in the layout and flow of the plant. Representatives from the bending and punching divisions discuss tooling innovations that have helped customers streamline their own operations.
Ultimately, attendees will learn lean manufacturing principles that will help improve shop productivity and minimise excess cost and waste. Derived from the Toyota Production System or JiT production, lean manufacturing is a proven method for optimising output.
The next event is Wilson Tool’s LEAN 1.0, which is suitable for those with no lean training, or a basic understanding of lean principles. Set to take place on 20 September at the company’s headquarters in White Bear Lake, Minnesota, the training will run from 08:30 to 15:00.
