Key Differences Between Billet, Cast, & Forged Manufacturing

Every part we produce starts with the right manufacturing process. At Astro Machine Works, we help you choose the best method—billet, cast, or forged—based on your project’s requirements for strength, precision, and cost efficiency. Our experience as a contract manufacturer allows us to handle every stage of production, from raw material to finished assembly.

Our team of engineers, machinists, fabricators and welders work side by side to deliver reliable, high-quality components. As a precision CNC machine shop, we focus on accuracy, consistency, and performance for industries that can’t compromise on quality.

Billet Manufacturing

Billet manufacturing begins with a solid block or bar of metal—often aluminum, steel, or titanium. This billet serves as the foundation for precision machining. Using advanced precision machining CNC equipment, the metal is shaped into its final form by cutting away material to achieve exact dimensions and surface finishes.

Billet manufacturing is often chosen when a part requires maximum strength and dimensional accuracy. Because the billet has a uniform grain structure, the finished part is more durable and less prone to defects. It’s an ideal option for low- to medium-volume runs where precision and quality matter most.

Benefits of Billet Parts:

• Excellent structural integrity for critical applications
• Tight dimensional tolerances and smooth finishes
• Short lead times compared to casting or forging
• Cost-effective for smaller production quantities

Astro’s Billet Capabilities

Astro Machine Works operates as a precision CNC machine shop equipped with multi-axis machining centers that produce detailed billet parts with high accuracy. Every part is machined to meet exact specifications and thoroughly inspected before delivery.

Our engineers, machinists, fabricators and welders also support projects that combine machined billet components with welded assemblies, ensuring compatibility across manufacturing stages. Through our contract manufacturing services, we manage the entire process—from billet selection and machining to finishing and assembly—so you receive a complete, production-ready solution.

Cast Manufacturing

Casting involves heating metal until it becomes molten, then pouring it into a mold that defines the desired shape. Once cooled, the metal solidifies and is removed from the mold. This process is ideal for producing complex geometries or parts with internal cavities that would be difficult or costly to machine from solid metal.
Benefits of Casting:

• Well-suited for high-volume production
• Capable of producing intricate shapes and details
• Offers a variety of material options
• Reduces machining time and material waste through near-net-shape results

Astro’s Expertise in Cast Component Finishing

Astro Machine Works specializes in precision machining CNC operations that take cast components and bring them to final specifications. Our team is highly skilled in machining, finishing, and assembling cast parts for industries like aerospace, medical, and industrial equipment.

Our engineers, machinists, fabricators and welders often work alongside machinists to modify or assemble cast parts that require additional structural support. By combining precision machining and fabrication, we deliver cast components that are accurate, functional, and ready for service.

Through our contract manufacturing approach, customers benefit from a single point of contact for machining, inspection, and final assembly. That means fewer handoffs, shorter production times, and consistent quality from start to finish.

Forged Manufacturing

Forging involves heating metal until it’s pliable and then shaping it using compressive forces, such as hammering or pressing. Unlike casting, the metal never melts—this preserves its grain structure and produces parts with exceptional strength and durability.

Advantages of Forged Components:

• Superior mechanical strength and resistance to fatigue
• Excellent performance under stress or high load
• Suitable for aerospace, energy, and heavy industrial applications

Astro’s Role in Forged Component Processing

Forged components often require precision finishing to meet final specifications. Astro’s precision CNC machine shop is equipped to machine forged blanks into accurate, fully finished parts. We handle critical operations such as drilling, turning, and milling with tight tolerances.

Our engineers, machinists, fabricators and welders provide additional support for assemblies that combine forged parts with machined or cast components. The result is a seamless integration of strength, precision, and craftsmanship.

As part of our contract manufacturing services, Astro manages the complete process—from machining and welding to inspection and delivery—giving you confidence that every forged part meets exact requirements for strength and performance.
