The Complete Injection Molding Process Explained (From Tooling to Production)

As a full-service injection molding manufacturer, we manage every phase of production—from planning and tooling to molding, assembly, and quality inspection. Our goal is simple: deliver high-quality, high-volume plastic parts on time and on budget while maintaining consistent, repeatable performance.

Whether we’re producing components for the automotive industry or expanding into appliance manufacturing, our process is built around precision, efficiency, and customer partnership. Here’s a clear look at how our injection molding process works from start to finish.

1. Planning & Project Integration

Every successful molding program begins with strategic planning. We start with an in-depth consultation to understand your part requirements, performance expectations, materials, timelines, and budget.

From there, we integrate your program into our production schedule to ensure tooling, materials, and machine capacity are aligned well before production begins.

This early alignment eliminates bottlenecks, reduces risk, and guarantees a smoother launch.

2. Tooling Development & Prototype Management

Tooling is the foundation of any injection molding project. That’s why we provide complete tool-build management, handling both prototype and full-production molds.

Our capabilities include:

  • Prototype tooling so you can evaluate parts before full commitment
  • Production tooling engineered for high-volume, long-term durability
  • Tight coordination with toolmakers to ensure accuracy and timing
  • Tool qualification to verify performance before release

We make sure every mold is built to meet your specifications, production volume, and material requirements.

3. Material Selection & Mold Setup

Choosing the right resin is critical for part performance and manufacturability. We process a wide range of materials — including ABS, PP, PA6, PA66, TPO/TPE, and glass- or talc-filled resins — allowing us to support both standard and highly engineered applications.

Once materials are selected, we set up the mold on one of our 18 injection molding machines, ranging from 100 to 550 tons, in our 58,000 sq. ft. climate-controlled manufacturing facility. A stable environment ensures consistent cycle times and improved part quality.

4. Production & Quality Control

When production begins, we bring together automation, precision equipment, and a strict layered quality control process.

Our production environment includes:

  • Climate-controlled facility to ensure dimensional stability
  • Real-time monitoring and ERP integration for full process visibility
  • Automated systems and robotics (where applicable) for consistency
  • Skilled operators trained to quickly identify variances
  • A multi-step quality process involving operators, quality inspectors, and final sign-off

Every part that leaves our facility has passed through multiple checkpoints to ensure it meets your exact specifications.

5. Secondary Operations & Value-Added Services

Many parts require additional finishing after molding — and we handle that in-house to shorten your supply chain and reduce lead times.

Our secondary services include:

  • Assembly
  • Vibration welding & hotplate welding
  • Post-molding embellishment such as clips, collars, inserts, and foam applications

By managing these operations internally, we deliver fully finished components ready for installation or downstream assembly.

6. End-to-End Project Delivery

Our customers count on us not just for parts, but for reliability and full program support. From initial planning through production and delivery, we focus on:

  • Precise scheduling
  • Transparent communication
  • Reliable production timelines
  • Strong quality systems
  • Flexible volume capabilities

This comprehensive approach is designed to eliminate uncertainty and keep your project on track — whether it’s a small run, high-volume automotive program, or a new venture into appliance components.

Why Our Process Works

Because we manage every stage under one roof — design support, tooling, molding, assembly, and quality — you get:

  • Faster project launches
  • Fewer production interruptions
  • Lower overall cost
  • More consistent part quality
  • A single point of accountability

It’s the reason customers rely on us for dependable, long-term molding partnerships.
