What are the advantages of CNC machining over plastic injection molding?
Here are some of the advantages of CNC machining over injection molding:
2. CNC machining is suitable for a wide range of materials, as it can cut different types of materials, including plastics and metals.
3. Because the CNC machine instructions and fixtures are included in the program, these programs can be quickly changed to accommodate successive design iterations, making it easy to modify part designs.
4. Compared to injection molding, CNC machining does not require complex molds, resulting in faster mold delivery times.
What are the disadvantages of CNC machining compared to plastic injection molding?
1. Due to the longer cycle time required to produce each part, CNC machining has a relatively higher per-part cost in high-volume production.
2. CNC machining is labor-intensive because the workpiece, finished part, tooling, and toolholders must be mounted and removed from the machine depending on the job requirements.

The intersection of machining plastics, accurate machining techniques, and aerospace machining requirements represents the cutting edge of modern manufacturing. While each area has unique demands, lessons from one domain often translate to improvements in others. Aerospace drives advancements in difficult materials, accurate machining pushes measurement technologies, and plastic machining innovations lead to better surface finishes across all materials.
Manufacturers investing in these interconnected capabilities position themselves to meet the most challenging requirements across medical, defense, transportation, and industrial sectors.
