Precision Plastics Machining

Automation Plastics offers precision plastic machining services that enhance the performance, quality, and functionality of injection molded components. By combining injection molding with CNC machining, we give customers the ability to achieve features and tolerances that would otherwise require complex tooling or costly mold modifications.

Our expertise in post-mold machining of plastic parts allows for greater design flexibility, improved sealing performance, and tighter dimensional control—without sacrificing efficiency.

Expanded Capabilities Through Machining

Machining molded plastic components allows us to create high-precision features that are difficult or inefficient to achieve through molding alone.

With our capabilities, we can deliver:

• Precision machined threads with superior consistency and fit

• Flash-free O-ring grooves for improved sealing performance

• Smooth sealing surfaces for critical applications

• Tight tolerance features without complex tooling

• Reduced need for side actions and unscrewing cores

This approach helps customers lower tooling costs, simplify mold design, and improve part performance.

CNC Machining for Plastic Components

Our facility is equipped with CNC lathes and vertical milling machines dedicated specifically to plastic machining, ensuring optimal performance when working with engineered thermoplastics.

We specialize in:

• Post-mold machining of injection molded parts

• CNC turning and milling for plastic components

• Threading, grooving, and sealing surface finishing

• Custom machining for tight tolerance applications

By machining parts after molding, we achieve greater repeatability and precision compared to molding-only solutions.

Precision & Tolerance Control

Automation Plastics is capable of holding tight machining tolerances on plastic components, ensuring consistent fit and function across high-volume production runs.

• Typical Machining Tolerances: ±0.002"

• High repeatability across production volumes

• Improved dimensional stability for critical features

This level of precision makes us a strong partner for applications requiring high-performance plastic components with exacting specifications.

Why Combine Injection Molding with Machining?

Customers choose Automation Plastics for integrated molding and machining because it delivers both cost and performance advantages:

• Eliminates complex tooling and reduces upfront costs

• Improves critical feature accuracy and sealing performance

• Increases consistency vs. molding alone

• Allows for faster design changes and flexibility

• Reduces risk in high-precision applications
