Avoid Failure
Identify Tooling & Molding Risks Before Steel is Cut
Preventing problems before they arise is crucial in the injection molding process. Our DFM-first approach helps identify tooling and molding risks early, saving you time and resources by addressing issues such as:
Warpage
Sink marks
Flash
Short shots
Weld line strength problems
Fiber orientation distortion
By addressing these challenges early in the process, we help ensure your product’s success from the first shot to mass production.
Stable Output
Repeatable Processes for Long Production Runs
At Haumann Group, we focus on high-volume injection molding with consistent output. Our advanced process control systems ensure your production runs smoothly and predictably, even across long production cycles.
Stable cycle times
High repeatability
Consistent part quality
With our precision-driven process, you can scale with confidence, knowing that every part will meet the same high-quality standards.
Dual Site Scaling
U.S. Responsiveness + China Scale & Cost Control
Haumann Group’s dual-site manufacturing model offers the best of both worlds:
