Scholz HTIK is an innovative supplier for high-precision plastic gears, with a remarkable 50-year legacy in injection moulding. Its expertise lies in crafting gears with impeccable geometry, tailored to meet diverse needs, from noise, vibration and harshness (NVH)- optimised operation to micro gears with a normal module of 0.1 mm. This mastery is born from a deep-seated commitment to precision, fuelled by cutting-edge technologies and the integration of the latest software programs, such as reverse engineering. It conducts tribological investigations and optimises noise and load capacity to produce products that epitomise durability and reliability.

More than just a manufacturer, Scholz HTIK operates as a comprehensive service provider, guiding customers from initial conception to meticulously crafted final products. With a specialised mould construction and an end-to-end process encompassing engineering, mould testing and state-of-the-art measurement technology for quality assurance, it ensures that each gearing meets the highest standards. Whether companies require durable, high-precision, NVH-optimised or micro gears, Scholz HTIK offers bespoke solutions to fulfil their requirements.

“We don’t just work from drawings. We immerse ourselves in the application to speak the same language as our clients,” says Dr Andreas Langheinrich, gear expert at Scholz HTIK. This deep understanding guarantees that each gear produced is a vital machine element that performs reliably under specific conditions.

The team comprises seasoned professionals, many of whom have been with the company for decades, contributing to an extensive reservoir of expertise. Langheinrich, with over twenty years in gearing, leads the team to pioneer the potential of plastic gears. Their deep-rooted expertise allows them to tackle complex challenges and deliver solutions beyond conventional expectations.

For example, when a tier-one supplier approached Scholz HTIK regarding the NVH-behaviour of a four-stage gearbox used in the rear door mechanism of a leading German car manufacturer’s vehicles, it rose to the occasion.

The issue stemmed from the inadequacy of a plastic wheel in the first gear stage, which failed to meet quality standards. Leveraging expertise and precise engineering capabilities, Scholz HTIK designed and produced a superior gear component, significantly improving the NVHperformance of the tailgate drive system.

In another instance, a tier-one supplier tasked Scholz HTIK with producing a helical gear for an e-bike drive project. Delivered to a large OEM, these gears played a crucial role in ensuring functionality and performance, earning the OEM’s trust.

Scholz HTIK’s approach involves supporting clients in optimizing or enhancing their systems and components. Rather than strictly adhering to initial specifications, the company provides alternative solutions, drawing from extensive expertise and experience.

The commitment to precision is also reinforced by state-of-the-art equipment and quality technology. Scholz HTIK ensures that every gearing meets exacting standards using tactile measuring machines, computer tomography and optical measurement systems. The company’s ability to trace each specific production batch underscores its focus on quality and accountability. This approach to quality technology is supported by advanced data recording of the injection moulding process, ensuring comprehensive traceability and reliability.

Currently, Scholz HTIK is deeply immersed in the micro-mobility sector, focusing on e-bikes and micro cars with power outputs ranging to 10 kilowatts. A significant challenge lies in the widespread use of high performance plastic materials, which, while common, are often viewed as less reliable than traditional steel components. Scholz HTIK engages in various research associations to shift the prevailing perception towards plastic as a viable material for machine elements.

Constantly pushing the boundaries of what plastic can achieve, Scholz HTIK not only meets but mostly exceeds its customers’ expectations. This relentless pursuit of perfection, backed by decades of experience and cutting-edge technology, ensures that Scholz HTIK remains at the forefront of high-precision plastic gear manufacturing.
