Your Trusted Partner for Custom Plastic Parts

Houston-Based Injection Molding | German Engineering | Global Production

Trusted by global brands. Built for long-term manufacturing partnerships.

Our Story: Engineering a Better Manufacturing Partnership

Haumann Technology was founded to solve a critical challenge in manufacturing: how to get the precision of German engineering with the flexibility and scale of global production, all while having reliable local support in the USA. We are not just another injection molding supplier; we are your dedicated engineering partner. From our headquarters in Houston, Texas, we work with you from the initial design (DFM) to the final delivery of your custom plastic parts, ensuring quality, transparency, and a resilient supply chain.

Who we are

Engineering led manufacturing, built for long-term partnership.

Haumann operates at the intersection of engineering, tooling, and injection molding. We work closely with customer engineering and sourcing teams to transform early-stage product concepts into manufacturable, repeatable, and high-quality plastic components. Rather than acting as a commodity supplier, we operate as a long-term manufacturing partner, supporting informed engineering decisions early in the product lifecycle and ensuring stable production performance over time.
