First：How do we define a custom forged metal part?
Unlike cast or machined parts, custom forged components are made by compressing heated metal into the required shape, which refines the grain structure and eliminates weak points. This gives them exceptional durability, load-bearing strength, and resistance to fatigue, making them ideal for demanding industrial applications.
Metal forging is often chosen when parts must be extremely strong, reliable, and able to withstand heavy wear and impact. This process is widely applied in cars, airplanes, energy equipment, industrial machinery, and defense hardware — especially for parts that face constant pressure or harsh working conditions.
Technical Specifications of Custom Molded Components
The forging process enhances metallurgical structure by aligning the grain flow while closing internal voids and porosity. As a result, forged parts exhibit superior mechanical performance, with tensile strength and impact resistance often exceeding cast or machined equivalents by as much as 30%.
We offer forging solutions across multiple materials such as carbon steels, alloy steels, stainless steels, aluminum, titanium, and copper-based alloys. Our capacity covers parts from 0.5 kg to over 100 kg, tailored to design requirements.
Closed-die forging makes it possible to create everything from basic parts to detailed components with features like ribs, bosses, and gears — all with precision and consistency.
Modern forging presses operate with automated feeding, trimming, and transfer systems to support continuous production, ideal for mid to high volume OEM requirements.
Primary Forging Processes
- Open-Die Forging: Injection molding is a high-precision manufacturing method capable of producing complex geometries and holding tight tolerances. It is the optimal process for the high-volume production of thermoplastic components.
- Closed-Die (Impression-Die) Forging: Used for hollow components like bottles and containers, combining efficiency with durability.
- Hot Forging: is an efficient and economical process for shaping plastic sheets into durable trays, protective enclosures, and finished panels.
- Cold Forging: Perfect for bringing complex prototypes and low-volume custom designs to life quickly and without the expense of traditional tooling.
- Upset Forging: Achieve exceptional precision without the cost of tooling. Our machining service is perfect for producing low-volume specialty parts and functional prototypes from durable engineering plastics.
- Precision Forging:Create stronger, smarter components by seamlessly bonding different materials or embedding metal inserts directly into plastic during molding. This eliminates assembly steps and improves product performance.

Second: Your Guide to Forging Processes and PRIME’s Capabilities
Comprehensive for Guidance
For both newcomers and experienced buyers, this section highlights the fundamentals of forging and PRIME’s role in producing high-quality components. You’ll learn about core processes, major benefits, and how our advanced capabilities solve challenges in strength, precision, and productivity.
Understanding Metal Forging: Built on Strength
Forging is a metal forming technique that shapes material under compressive forces using hydraulic or mechanical presses. By refining the grain structure and removing porosity, the process yields components with superior mechanical performance. It is commonly applied in structural parts, powertrain systems, and heavy-duty industrial applications where safety and reliability are critical. At PRIME, our forging capabilities ensure excellent material flow, optimized strength-to-weight performance, and extended service life for industries such as automotive, aerospace, and energy.
Application-Specific Forging Capabilities
The choice of forging method directly impacts quality, efficiency, and overall cost. PRIME’s experts carefully review your design specifications and performance goals to recommend the best-fit solution. Here are some of the main forging processes we employ.
1. Forging Large Parts with Structural Integrity Through Open Die Processes
In open-die forging, metal is compressed between flat dies, allowing free deformation in several directions. This method is commonly used for large parts like cylinders, blocks, flanges, and shafts, ensuring improved grain alignment and superior strength. PRIME’s advanced CNC-controlled presses guarantee precision, reduced stress concentrations, and repeatable quality.
2.Forming Complex Components with Precision Using Closed Die Forging
Known as impression die forging, this process uses shaped dies to press metal into intricate 3D forms through single or multiple cycles. It is well-suited for higher production volumes, producing near-net shapes with minimal waste and smooth surface finishes. PRIME supports this with custom die manufacturing, automated flash control, and precision trimming, achieving tolerances as fine as ±0.02 mm.
3. Efficient Metal Forming Without Heat: Cold Forging
Accelerate your product development with plastic CNC machining. This process delivers precision-machined parts from high-performance plastics without the delay or expense of tooling. It’s the fastest way to get functional prototypes, specialty components, and complex parts with exacting geometries into your hands.
4. Forging Precision Components with Minimal Machining
By shaping parts near their finished dimensions, precision forging minimizes secondary machining operations. It is particularly suited for demanding applications such as aerospace components, turbine blades, and gear blanks. PRIME leverages state-of-the-art simulation tools and flashless forging technology to achieve accurate, efficient, and repeatable production.
