FOCUS ON METAL FORMING

Advanced technology from TRUMPF enables the company to achieve high-volume production with consistent quality.
“ We want to match the standards of established OEMs,” Wahyudi said.“ To do that, we
We can also optimise the design need a proper production line, efficient schedules and clear daily of each part by using innovative targets. The biggest challenge for design formats and manufacturing my generation is changing the technologies. That makes the mindset around manual labour.” process simpler and reduces costs
The transformation began in 2015 when the family discovered TRUMPF technologies at a trade show. At first, Yohan’ s father, Tatang, was sceptical about spending large sums on advanced technology and automation. He felt that processing body parts wasn’ t complicated enough to justify such a step. But after a strong financial year, the family decided to take the leap.
“ We stepped out of our comfort zone and invested in new technology,” Yohan said. That year, they purchased a TruLaser 3030 from TRUMPF for sheet metal processing.
“ We immediately saw the benefits of automation for things such as the baggage compartments,” outlined Yohan. Previously, employees needed five or six separate parts to build a baggage compartment door. Nowadays, they take a single sheet of metal, cut it with the TruLaser 5030 and shape it with the TruBend Center 5030.
“ This new approach eliminates welding entirely, much to the amazement of our customers!” confirmed Yohan.
The consistent quality offered by TRUMPF machines, according to the bus body manufacturer, has a wide array of benefits.
“ It allows us to oversee the entire production process, so we can prioritise which parts are needed most urgently and which can wait,” Yohan highlighted.“ We can also optimise the design of

Looking to the future
Next year, Yohan plans to invest in TRUMPF’ s Oseon software.
“ A bus consists of thousands of parts. If we can make our production more efficient, we’ ll save time and money. That’ s where Oseon comes in,” he explained.“ It feels like 2015 all over again, before we bought our first TRUMPF machine. We know what the technology can do, it’ s just a question of learning to make the most of it.”
Two generations. Founded in 1983 by Tatang Wahyudi, the company is now shaped by his son Yohan’ s vision of cuttingedge production.
