OEMs across multiple industries choose Haumann Group not just for individual services, but for a manufacturing platform built around precision injection molding, engineering discipline, and production reliability. Our approach is designed to reduce risk, improve part consistency, and support scalable production across diverse market requirements.
Injection molding–led manufacturing platform
Our capabilities are centered around custom plastic injection molding, supported by tooling, DFM, machining, and assembly—ensuring consistency from prototype through high-volume production.
Engineering-driven production readiness
Every program begins with manufacturability and feasibility reviews to identify risk early and align tooling, materials, and processes before production ramps.
German-engineered tooling and process control
Precision mold design, controlled tooling strategies, and repeatable process discipline ensure tight tolerances and predictable part performance across production cycles.
Support for complex materials and applications
We support engineered resins, multi-material designs, and composite components across performance, industrial, and consumer-facing applications.
Dual-base manufacturing support (USA + China)
Houston-based engineering and project coordination combined with scalable global production enable cost-effective, high-volume manufacturing without sacrificing quality or communication.
Haumann Group supports OEM programs through a structured, engineering-driven manufacturing process designed to reduce risk and ensure production readiness. Each step in our workflow is aligned around custom injection molding and high-volume manufacturing, allowing us to support products from early evaluation through stable, repeatable production.
Our OEM plastic injection molding by industry approach ensures consistent quality, repeatability, and cost efficiency across diverse application requirements.
We begin with a Design for Manufacturability (DFM) and feasibility review to evaluate part geometry, material selection, tolerance requirements, and production volume. This step identifies potential risks early and aligns design intent with injection molding realities.
Our engineering team designs and builds precision injection mold tooling optimized for part performance, repeatability, and long-term production stability. Tooling strategies are selected based on volume requirements, material behavior, and quality targets.
Initial samples and pilot runs are produced to validate tooling performance, dimensional accuracy, and process stability. Inspection methods such as first article inspection, CMM measurement, and 3D scanning ensure parts meet specification before production ramp-up.
Once validated, programs transition into high-volume injection molding with controlled process parameters and repeatable cycle performance. Production output is monitored to maintain consistency across batches and extended production runs.
As required, we provide CNC machining, secondary operations, and assembly to deliver production-ready components. Integrated post-molding operations reduce supplier handoffs and simplify OEM supply chains.
OEMs choose Haumann because we combine custom injection molding, engineering-led manufacturing, and global production scale into a single, reliable manufacturing platform. Our approach reduces risk, improves consistency, and supports long-term production success across industries.
