Forging
We support forging operations for high-strength components used in load-bearing and high-stress applications. Our forging work is carried out to meet defined dimensional, mechanical, and functional requirements, based on customer drawings and technical specifications.
Forging Capabilities
At A Glance
- Open and closed die forging
- Hot and cold forging
- Steel, aluminum, brass, and copper materials
- Component size and tolerance controlled by forging method and die design
Forging Operations & Execution Scope
Forging Methods & Processes
Open-die and closed-die forging are supported using both hot and cold forging processes. Method selection is based on material type, component geometry, and functional requirements to achieve the required strength and dimensional control.
Materials & Component Control
Forging is carried out using steel, aluminum, brass, and copper. Component size, geometry, and achievable tolerances are governed by the selected forging method and die design.
Size Capability & Tolerances
Maximum forging size supported is 60 mm × 110 mm in length. Typical achievable tolerances are up to ±0.05 mm, depending on part geometry, material, and process configuration.
Lead Times & Capacity Planning
Raw material procurement typically requires approximately four weeks, followed by forging lead times of around one week. Capacity and scheduling are planned based on material availability, forging method, and die configuration.
Forging Services at MMI
We carry out forging using mechanical and hydraulic presses to produce precision components in low carbon steel, aluminum, brass, and copper. Mechanical presses support high-speed, repeatable production, while hydraulic presses are used for controlled force and complex geometries. Forging methods including open die, closed die, drop forging, press forging, and forward and backward extrusion are selected based on material behavior, part geometry, strength requirements, and production volume. Forging programs support prototype, low-volume, and production requirements based on customer specifications. Die design and maintenance are handled in-house to maintain repeatability and dimensional consistency. Forging is executed in line with customer drawings, tolerances, and delivery conditions, with post-forging operations such as machining, drilling, tapping, heat treatment, and surface treatment supported where specified.
Why Choose MMI for Forging?
Forging Method Flexibility
We support open die, closed die, hot forging, cold forging, drop forging, press forging, and extrusion-based processes, selected based on application requirements.
In-House Die Design and Control
Our dies are designed, manufactured, and maintained in-house to support dimensional accuracy, controlled grain flow, and repeatability.
Process Control and Quality
We manage forging conditions to ensure stable results across production runs and to achieve the required strength and performance characteristics for each component.
Available Secondary Processes
Forging can be carried out on its own or combined with downstream steps such as machining, heat treatment, and surface finishing, depending on overall program needs.
Materials
Material selection and forging parameters are defined strictly by customer drawings and technical specifications.
Low Carbon Steel
Low carbon steel forgings are produced for components requiring strength, ductility, and machinability. Material grades and properties are controlled as specified.
Post-Forging Operations
Machining is performed to achieve final dimensions and tolerances as specified on customer drawings.
Defect Management
- Root Cause Analysis: Non-conformities are investigated to identify underlying causes and prevent recurrence
- Die Revalidation: Forging dies are reviewed and revalidated following defects or process changes
- Rework and Reprocessing: Non-conforming parts are reworked or reprocessed where permitted by specification, with all actions documented and verified prior to release
- Corrective and Preventive Actions: Corrective and preventive actions are implemented to maintain process stability and quality compliance
