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.
Haumann works side-by-side with customer engineering and sourcing teams to transform early-stage product concepts into manufacturable, repeatable, high-quality plastic components.
Our teams engage early in the development process, supporting design for manufacturability, tooling strategy, and production planning to reduce risk and accelerate product readiness. Rather than acting as a transactional supplier, we integrate into our customers’ workflows to enable informed engineering decisions, stable production performance, and long-term program success.
Haumann Technology delivers precision manufacturing solutions that combine German engineering rigor with scalable global production.
Founded by German/Austrian engineers, we support complex plastic part development from concept through mass production, integrating disciplined engineering methodology with flexible manufacturing execution.
We operate fully integrated engineering, tooling, and injection molding manufacturing facilities in both the United States and China, providing customers with local U.S. engineering and production capability alongside high-volume, cost-efficient manufacturing in China. This dual-base structure enables fast technical communication, shortened development cycles, and a resilient supply chain.
Our process begins at the design stage. Through DFM-driven engineering, mold-flow simulation, and pre-deformation analysis, we identify potential risks such as warpage, shrinkage, weld lines, and tolerance stack-ups before tooling begins. This design-first approach minimizes downstream modifications, reduces tooling iterations, and accelerates time to stable production.
Haumann provides end-to-end manufacturing services including tooling design and fabrication, injection molding, CNC machining, rapid prototyping, and integrated assembly. Functional prototypes in as fast as 20 days enable rapid iteration, design validation, and a smooth transition into production programs.
Over the past 15 years, Haumann has built long-term partnerships with multiple U.S. Tier 1 suppliers, German and European OEM brands, primarily across automotive, industrial, and performance consumer footwear markets. These relationships are rooted in early engineering engagement, robust tooling development, and consistent production performance, supporting demanding, mission-critical production programs.
With our U.S. engineering and manufacturing base in Houston, Texas, and scalable production facilities in China, our teams work closely with OEMs and product engineers to optimize part design, improve manufacturability, and ensure consistent quality throughout the product lifecycle.
Haumann is more than an injection molding supplier — we are an engineering-focused manufacturing partner committed to precision, transparency, speed, and long-term reliability.

Haumann supports OEM customers across the following industries:
Our engineering approach is focused on making informed decisions early where cost, quality, and manufacturability are determined.
We emphasize:
Design-for-manufacturing from the earliest project stages
Process stability, repeatability, and dimensional control
Data-driven quality validation and risk assessment
Long-term mold lifecycle and production planning
By addressing manufacturability risks upfront, we help customers reduce redesign cycles, avoid production delays, and control total program cost.
Engineering-driven decisions validated through simulation and production data
Fast response without engineering compromise.
Haumann is structured for rapid execution through short feedback loops, clear communication, and early engineering involvement.
Our dual manufacturing footprint combines local engineering support with scalable global production, delivering speed, flexibility, and resilient supply chains.
Our Houston, TX facility serves as the engineering, customer interface, and program execution hub for North American clients.
The team supports early-stage DFM, engineering validation, rapid prototyping, pilot runs, and on-site project coordinationensuring technical decisions are made early and communicated clearly throughout the program lifecycle.
This local presence enables fast response, transparent communication, and direct engineering engagement from concept through production.
Our Foshan, China facility provides advanced tooling, precision injection molding, and scalable production execution, closely integrated with our U.S.-based engineering team.
The site supports complex tooling programs, high volume manufacturing, and consistent quality control enabling efficient scale up while maintaining engineering intent and dimensional integrity. Together, our China operations function as a seamless extension of our U.S. engineering organization.
