Rapid Prototype Injection Molding

What Is Rapid Prototype Injection Molding?

Let’s keep it simple:
Rapid prototype injection molding is a process that uses quick-turn tooling to produce short runs of injection molded parts — often for testing, design validation, or market trials.

Instead of waiting months for traditional steel molds, we create rapid injection molds using aluminum or hybrid materials that can be produced in days.
This gives you real, functional plastic parts made from the same materials you’ll use in production — not 3D-printed substitutes.

In short:

• Faster than traditional tooling

• Lower upfront cost

• Production-grade results

• Perfect for prototypes and bridge tooling

How Rapid Injection Molding Works

At LXG Injection Molding, our rapid injection molding process follows a proven, streamlined workflow:

1. Design Review
   You share your CAD model, and our engineering team reviews it for manufacturability. We’ll recommend minor tweaks (if needed) to optimize for rapid prototyping injection molding.

2. Tooling Creation
   We build the rapid tooling injection mold using high-speed CNC machining or EDM. This aluminum or hybrid mold is lighter, faster to machine, and ready for short production runs.

3. Material Selection
   We help you choose the right resin — from commodity plastics like ABS and PP to high-performance options like PC, PEEK, or medical-grade resins.

4. Sample Molding
   Once the tool is ready, we produce your prototype injection molded parts. This gives you functional samples you can test for fit, strength, and performance.

5. Feedback & Iteration
   You test, validate, and provide feedback. If needed, we adjust the tooling or process to refine results.

6. Production Transition
   Once the prototype is validated, scaling to full production is seamless. Your data, tooling, and part geometry are already optimized.

This step-by-step method lets you go from idea to product in as little as 5–10 days — without sacrificing precision or durability.

Why Rapid Injection Molding Is Game-Changing

The beauty of rapid injection molding prototyping lies in its flexibility.
It’s designed for speed, accuracy, and affordability — making it perfect for modern product development cycles.

Here’s why companies around the world love it:

⚡ Faster Time-to-Market

Traditional mold-making can take 8–12 weeks.
With rapid tooling injection molding, you can have production-quality parts in a few days.
That means faster testing, faster launches, and faster revenue.

💰 Lower Costs

By using aluminum tooling and optimized processes, we reduce both time and cost.
You get high-quality molds without the heavy investment of traditional steel tooling.

🔄 Easy Design Iteration

Want to tweak your design after testing? No problem.
Our rapid prototyping injection molding system allows quick adjustments — helping you refine designs before committing to full production.

🧩 Production-Grade Materials

Unlike 3D printing, rapid prototype injection molding uses real resins.
That means your test parts perform exactly like the final product.

🌍 Scalable Manufacturing

Start with 50 parts. Scale to 500,000.
Our rapid injection molding process scales easily — from prototyping to mass production.
