Our Tooling and Design Services

Turning Concepts into Reality: From Prototype to Production

At Harmony Coast, we deliver tailored solutions that bridge the gap between product design and short-run manufacturing. Our expertise in additive manufacturing allows us to produce precise, functional tooling for silicone, urethane, and injection applications—helping you move from concept to reality faster. By combining advanced digital methods with practical engineering knowledge, we ensure high-quality results that accelerate your development process.

 

Our team works closely with you to streamline production, reduce costs, and improve the performance of your parts. Whether you need one-off prototypes or small-batch molds, we provide the agility and precision your project demands.

 

We are dedicated to helping innovators, manufacturers, and entrepreneurs bring their ideas to life with efficiency and accuracy. Harmony Coast offers end-to-end support with these core services:

  • Additive Manufacturing: High-resolution 3D printing to create accurate patterns, masters, and mold tooling.

  • Silicone & Urethane Tooling: Flexible, cost-effective molds for prototyping and low-volume production.

  • Injection Mold Design: Short-run mold solutions designed for accuracy, repeatability, and speed.

  • Composite Tooling: Precision-designed molds and fixtures for composite layup, engineered for durability, and dimensional accuracy.

  • Value-Added Support: Engineering consultation, CAD design, and visual prototyping to strengthen every stage of your project.

At Harmony Coast, we believe product development should be efficient, flexible, and tailored to your needs. Our approach combines advanced additive manufacturing with traditional mold-making expertise, allowing us to guide you from early concepts through functional prototypes and into small-batch production.

 

Whether you’re refining a design, testing a material, or preparing for low-volume manufacturing, our team is here to provide the precision and speed your project demands.

Rapid Production

Rapid production means building parts, molds, or components quickly and in small batches, exactly when you need them. This method helps businesses stay agile, reduce costs, and respond quickly to market opportunities.

Benefits of Rapid Production

  • Lower upfront tooling costs
  • Faster turnaround for urgent projects
  • Greater flexibility in materials and applications
  • Reduced waste and better resource efficiency
  • Reliable quality for low- to mid-volume runs
  • Adaptable solutions for changing customer demands

Prototyping

Prototyping gives you the ability to test and validate your designs before investing in full-scale production. Using additive manufacturing, silicone and urethane molding, and precision short-run tools, we create functional models and end-use parts that bring your ideas to life.

Benefits of Prototyping

  • Shorter design cycles with quick iterations
  • Early testing of form, fit, and function
  • Cost-effective validation before scaling
  • High-resolution detail for visual and functional models
  • Improved confidence in production decisions
  • Tailored solutions for unique product requirements
