Injection Molding Capabilities

Our team supports a wide range of molding applications and production volumes.

High Cavitation Molding

Automation Plastics specializes in high-cavitation injection molding programs where productivity, cycle time, and cost-per-part are critical. Our experience with multi-cavity tooling allows customers to maximize output while maintaining consistent quality.

Precision Molding for Small Features

We produce precision molded components featuring micro-sized details, tight tolerances, and small orifice geometries used in demanding applications.

Insert Molding & Over-molding

Our insert molding and over-molding capabilities combine multiple materials and components into a single finished part, reducing assembly costs and improving product performance.

Heavy Wall Molding

We are experienced in molding thick-wall plastic components that require dimensional stability, structural integrity, and consistent processing.

Precision Injection Molding

For applications where tolerances, repeatability, and quality are critical, our scientific molding approach ensures stable, repeatable production performance.

Engineering Support & DFM Expertise

Successful injection molding begins long before production.

Our engineering team works closely with customers during product development to identify opportunities to:

  • Improve manufacturability

  • Reduce cycle time

  • Optimize material selection

  • Improve mold flow

  • Reduce scrap

  • Increase cavitation where appropriate

  • Lower overall part cost

By engaging early in the development process, we help customers avoid costly tooling changes and accelerate product launches.

Materials Expertise

Automation Plastics processes a wide variety of commodity and engineering-grade thermoplastics.

Common materials include:

  • Polypropylene (PP)

  • ABS

  • Nylon (PA)

  • Glass-Filled Nylon

  • Polycarbonate (PC)

  • TPE / TPU

  • Engineered Resins

Our team can assist with material selection based on performance requirements, cost targets, environmental conditions, and manufacturability.
