Fictiv Urethane Casting Advantages

Production Quality at Low Volumes

This process is a quick, cost-effective way to produce 10-200 units with production-level quality. Typically, each silicone mold will produce 20 castings.

Complex Elastomeric Parts

Urethane casting is ideal for prototyping elastomeric parts such as complex gaskets and overmolds on rigid parts.

High Level of Detail

Urethane casting allows for almost limitless complexity, including sharp internal corners unachievable with CNC machining, and designs without draft or uniform wall-thickness that can’t be injection molded.

Technology Overview

What is Urethane Casting

About the Urethane Casting Process

Urethane casting (also known as RTV molding, cast urethane, and silicone molding) is a fabrication method that uses silicone molds to produce production-quality plastic parts.

Urethane Casting production consists of three main steps:

1. Build a master pattern using 3D printing or CNC machining
2. Build the mold by pouring platinum silicone around master
3. Pour liquid polyurethane resin into mold, create polyurethane casting under vacuum

Advantages of Urethane Casting

With urethane casting, you can get production quality parts at low volumes and without the high costs and lead times of steel or aluminum tooling. This is helpful for bringing new products to market where you may want production-grade products to test with new customers and markets and validate your design hypotheses before making a substantial investment to scale manufacturing.

Urethane Casting Design Considerations

If you are familiar with designing parts for injection molding, you can apply the same best practices and rules of thumb to design parts for urethane casting.

Urethane Casting Design Guide

Best Practices for Urethane Casting Design Urethane casting, also known as RTV, or room temperature vulcanization, is a very flexible and forgiving process. Most parts that can be 3D printed or CNC machined can also be urethane cast. Different from 3D printing and CNC machining, urethane casting production-quality plastic parts with almost limitless complexity. In […]
