Your Local Partner for Development and Plastic Engineering

With the incorporation of 4Tec solutions AG in Zürich in 2015, this concept continues. Here our experts for plastic engineering and mechanical design create innovative solutions to meet the complex requirements of our customers. Together with our team in Shenzhen we guarantee the technical feasibility, which is essential for a successful production.

A Strong and Stable Supply Chain, Worldwide

A reliable supply chain in China, which we continually improved over the last few years, is part of our key strengths. We maintain stable and strong relationships with professional suppliers for all common mechanical production processes, including PCBA manufacturing.

Our team in Shenzhen consists of experienced purchasing and production engineers who check the feasibility and define the best manufacturing method.

Experienced quality supervisors ensure that defined quality standards are met at all times. We support our suppliers on site and guarantee a smooth production by providing the right equipment if necessary.

We Think Production

Excellent quality, reliable lead times, affordable prices. With our own manufacturing facility and a motivated team, we offer all three to our customers for small to medium sized productions runs of sub-assembly groups and complete products.
