What MG3 does best.

In a complex environment with intricate supply chains, transportation constraints, and political global challenges, having a reliable local partner like MG3 offers significant advantages. Our stability in localized manufacturing ensures speed, accuracy, and security for your proprietary designs. With high-speed machines, integrated software, and domestic cold forming, we reduce scrap, automate production to lower costs, and keep your product details secure, making us your best option in challenging times.

Cold Forming


Cold forming is a versatile process used to shape a wide range of fasteners with multiple diameters and internally threaded dimensions. This cost-efficient technique not only enhances the hardness and tensile strength of a part through material grain flow but also allows for the creation of complex shapes.


MG3 can cold form parts ranging from 2mm to 280mm in length and 4mm to more than 65mm in diameter, while also being equipped to meet challenging part requirements with the flexibility to adapt to product changes or immediate demand.


Cold-formed parts are ideal for a variety of applications and industries, including automotive, agriculture, civic, and construction sectors. Our parts are integral to thousands of applications, including suspensions, braking and powertrain applications, worldwide.

Secondary Machining


Machining is essential for creating highly precise and complex parts, allowing for exacting tolerances and intricate designs. When combined with secondary machining on cold-formed products, it enhances the functionality and precision of components, making them suitable for applications requiring stringent specifications.


MG3 offers machined components as well as secondary machining on cold-formed products, ensuring exceptional precision and quality to meet the most demanding requirements.
