HARTING Vietnam has partnered with surface finishing specialist Rösler to implement an advanced, fully interlinked mass finishing system at its new manufacturing facility. The system ensures outstanding corrosion protection, durability, and process efficiency, reinforcing HARTING’s commitment to quality and innovation in the rapidly growing Asia-Pacific market.
HARTING Technology Group, headquartered in Espelkamp (Germany), and one of the world’s leading providers of industrial connectors, has raised the bar for surface finishing in South-East Asia. With the launch of its new manufacturing facility in Hai Duong (Vietnam), the company has introduced a fully interlinked mass finishing system from Rösler Oberflächentechnik – a long-standing partner known for its technological excellence and service reliability.
In mid-2023, HARTING inaugurated the Vietnam plant as part of its ‘In the region for the region’ strategy, targeting the rapidly growing Asia-Pacific market. The new site specialises in the production of both small plastic and heavy-duty aluminium plug connectors, with a strong focus on high performance and sustainability. To uphold the group’s global standards of manufacturing quality and efficiency, HARTING opted for Rösler’s tried-and-tested surface finishing concept – already in use at sites in Germany and China.
“The outstanding relationship we’ve developed with Rösler over more than three decades, together with the high quality of their equipment, made this investment decision straightforward,” has stated Philipp Borcherding, Plant Manager at HARTING Vietnam.
The aluminium plug connectors manufactured in Vietnam are critical components used across a variety of sectors – from automotive and telecommunications to renewable energy and robotics. Much of the heavy-duty product output is destined for Japan and South Korea, where it supports applications in advanced robotics – reinforcing HARTING’s presence in future-oriented markets.
At the core of production is a precise, multi-stage finishing process. After die-casting and machining, the housings are contaminated with coolants and lubricants, requiring thorough cleaning and preparation before powder coating. This is carried out entirely within Rösler’s fully interlinked system, which handles everything from degreasing and deburring to drying – ensuring each component meets the highest standards in corrosion protection
and durability.
The finishing system comprises six integrated stages, beginning with a roller conveyor that delivers raw workpieces to a skip loader. Depending on component type, the operator selects the appropriate programme, after which the process is fully automated. Components pass through rotary vibrators, screening units, spray washing stations, and hot air dryers before being returned to customer bins.
“We developed and refined this process in close collaboration with HARTING to ensure seamless integration into their production environment. It delivers exceptional finishing results and meets HARTING’s stringent quality criteria,” has added Matthias Ender, Technical Sales Manager at Rösler.
Noise emissions are minimised thanks to a soundproof enclosure measuring 13x3.7m. Additionally, a smart water recycling unit, including a semi-automatic Z 800 basket centrifuge and vacuum evaporator, ensures environmentally responsible operation – a rarity in many facilities across the region.
We’re extremely satisfied with the Rösler system – from its sophisticated material handling and high degree of automation to its durable design and outstanding workplace safety features. The finishing quality of the parts is unmatched in the South-East Asian region. We’ve had nothing but positive experiences with Rösler worldwide. As we grow in this region, we fully intend to involve them in our development plans – their technology and support are integral to our success,” has concluded Philipp Borcherding.
