Our Custom Mold Tooling Capabilities
MFG One delivers high-precision custom mold tooling manufacturing with exceptional efficiency. Using advanced CNC machining technology and automation, we support both rapid prototyping and high-volume production.
Our US-based team has the capability to support complex geometries, scale production with 30–50 tools in parallel, and offer quick-turn prototyping alongside in-house design services.

Tooling Design & Engineering
As a turnkey custom manufacturing provider, our tooling design and engineering process is the foundation of high-quality, efficient plastic part production. We combine experienced engineers with advanced software to create molds optimized for manufacturability, performance, and longevity.
CAD/CAM Expertise
We create custom molds designed to handle intricate geometries, undercuts, and tight tolerances, making them ideal for parts with complex designs. We offer a range of custom injection mold tooling options.
- Our skilled design team utilizes industry-leading CAD/CAM software to develop precise 3D models of your mold, creating an accurate representation of the final part geometry.
DfM (Design for Manufacturability)
We work closely with our clients from the initial design stages to provide DfM feedback, optimizing the part design for injection molding, minimizing potential production challenges and reducing overall costs.
- During the mold design phase, we use the latest in simulation technology, such as Moldflow, to test for manufacturability of the part and the mold design itself. This allows us to identify and address potential issues.
Tooling Fabrication
Our state-of-the-art tooling fabrication facility brings your mold design to life with precision and efficiency.
High-Quality Tooling Steels
- We utilize a range of premium tool steels chosen for their specific properties to deliver optimal mold performance and longevity for each project.
- P20, S7, H13, and 420 stainless steel
- We carefully select the appropriate steel based on the application requirements and desired mold life.
Precision Machining
Our experienced toolmakers employ advanced CNC machining, EDM (Electrical Discharge Machining), and other precision machining processes to achieve exceptionally tight tolerances, down to +/- .001 inches. This results in the highest level of accuracy and repeatability in your finished parts.
Mold Longevity
Our molds are designed and built for long-term production. Many are capable of achieving 1 million shots or more, depending on the selected tooling steel and application requirements.
