The MECHITRONIC Group expands with Apex Machine Company and RK Ferramentaria
The MECHITRONIC Group, of which ERMO is part, continues its international expansion with the integration of two fast-growing companies in the Americas: Apex Machine Company (United States) and RK Ferramentaria (Brazil).
This strategic milestone strengthens the group’s global presence and reinforces its expertise in packaging technologies, tooling, and advanced industrial solutions.
A strategic expansion in the Americas
With these new additions:
- Apex Machine Company, based in Fort Lauderdale, brings recognized expertise in pretreatment, printing, quality control, and downstream automation
- RK Ferramentaria, located in Curitiba, stands out for its expertise in high-speed injection mold manufacturing
These complementary capabilities enable the MECHITRONIC Group to deliver an even more comprehensive and high-performance offering to customers worldwide.
Focus on RK Ferramentaria: 20 years of industrial excellence
Founded in 2005, RK Ferramentaria is today celebrating more than 20 years of expertise in:
- thin-wall food container molds
- catering applications
- medical applications
- closure molds
This evolution has been driven by strong customer trust and the continuous development of the team’s technical expertise.
A strong culture built on excellence and people
This commitment to quality lies at the heart of the company’s DNA, as explained by Mauricio Rosenstock, CEO of RK Ferramentaria:
What makes me most proud is the culture of excellence we built from day one. Because we started by supplying molds to our own family business, there was never room for compromise. Everything had to be perfect, with zero rework. This level of responsibility became part of our DNA. Even today, we move forward with the same philosophy: always delivering our very best so that our customers can succeed with confidence.
Each project is developed with a clear objective: achieving the highest level of performance.
This may require redesigning a project or investing additional time to ensure flawless quality.
People at the heart of the company
From the beginning, RK has fostered a strong family-business spirit.
Despite its growth (from 30 to 65 employees), the company remains deeply committed to its people, convinced that performance is driven by team engagement.
RK's core values by Maurico Rosenstock
Our first core value is people. We put significant effort into creating the best possible work environment because we believe strong businesses are built by motivated teams. Small companies naturally feel like families, and RK has always carried that spirit. (...)
When we produced around 20 molds per year with a team of 30 people, maintaining this closeness was simple. Today, with 65 people, the challenge is greater—but so is our commitment to preserving this culture. As we continue to grow, we will keep finding ways to strengthen the bonds within our team, even if that simply means organizing more barbecues every year.
A shared vision with ERMO and MECHITRONIC
The integration of RK Ferramentaria into the MECHITRONIC Group is a natural step.

The collaboration between RK and ERMO, initiated in 2018, has demonstrated strong alignment, built on shared values of excellence and performance.
A new international dimension
This integration opens new opportunities:
- For RK: ensuring long-term growth and sustainability
- For customers: benefiting from a broader and more integrated range of expertise
A key milestone for the future
With the addition of Apex Machine Company and RK Ferramentaria, the MECHITRONIC Group reaches a new milestone in its global development.
A clear ambition: to continue innovating, expanding internationally, and supporting customers with ever more advanced and high-performance solutions.
