- Rapid part production (not as fast as injection molding)
- Cheaper for smaller quantity runs
- Best for harder plastics
- Larger variety of materials available
- Allows for tighter tolerance and surface finishing
Injection Molding Services
- Uses custom mold (requires additional lead time and cost)
- Expensive to redesign (requires the creation of new mold)
- Fastest part production
- Cheaper cost per part with high quantity runs
- Ideal for producing parts made from softer plastics
- Rubber and flexible materials can use this method

CNC Machining Process Description
CNC machining is a subtractive manufacturing method where material is removed from a solid block using computer-controlled tools. The process begins with customer-provided CAD models, which are converted into precise toolpaths. Automated mills, lathes, routers, and multi-axis machines execute these toolpaths to create components that meet strict dimensional requirements.
Redstone Manufacturing uses both 3-axis and multi-axis machines to produce parts with complex features such as deep pockets, fine threads, undercuts, and tight-tolerance fits. Throughout the machining cycle, sensors and automated systems ensure dimensional accuracy, while finishing operations—milling, turning, drilling, tapping, and polishing—complete the part to the customer’s exact specifications.

FAQ's ABOUT OUR CNC MACHINING SERVICES
This depends on many factors. Simple, less complex parts with smaller quantities will have a shorter lead time. We offer a 3-5 week lead time.
Our manufacturing facilities have both milling and lathe machines. Both machines start with a block of the material then they remove material until each part reaches the desired specifications. In a lathe machine, the worked material spins while the cutting tool remains stationary. This machine is ideal for producing symmetrical cylindrical components. Milling machines work in the exact opposite way. The workpiece remains stationary while the milling cutting tool removes the necessary material.
CNC machining is more accessible than most people think. Advances in technology have helped reduce the cost. The overall cost will depend on the desired material and part specifications. CNC turning tends to be cheaper than milling, but a multi-axis machined part can be more expensive.
CNC machining is an efficient production process. While it still requires people to operate the machinery and replace dull cutting tools, a computer is mostly in control. This allows all of the major operations to be automated, which increases speed, overall quality, and accuracy.
CNC MACHINING MATERIALS
Redstone’s Manufacturing’s CNC machining services can utilize three different material types – steel alloys, aluminum, and plastics.
STEEL ALLOYS
Steel alloys are valued for their strength, durability, resistance to high temperatures, and corrosion. What makes this metal so valuable is the addition of alloying elements. A part’s application and desired shelf life will help determine what amounts of additional alloys are required.
Aluminum
Aluminum is one of the most commonly machined metals in the manufacturing sector because of its diverse mechanical properties. It is affordable, lightweight yet strong, durable, corrosion-resistant, and easy to shape, making it a popular choice in the aerospace, medical, and military sectors.
PLASTICS
High-quality plastic parts are cheap, durable, and lightweight compared to their metal predecessors. Their increase in popularity across countless industries comes from their lower manufacturing costs.
