What is Urethane Casting?

Urethane casting, also known as polyurethane casting or cast molding, is a versatile manufacturing process. It entails producing top-quality prototypes and low-volume production components by pouring liquid urethane material into molds to form objects. This technique is employed to craft a wide range of items, from small-scale prototypes to intricate parts.

Cast Urethane Molding Working Process

Overmolds is a multi-stage process that seamlessly combines different materials to create intricate and efficient parts. The overmoulding process involves several key steps
01

Mold Creation for Precision

We begin by crafting a mold designed to perfectly replicate the desired part, ensuring all intricate details are captured accurately.
02

Expert Material Mixing and Pouring

Our skilled technicians masterfully mix and pour polyurethane molding material, ensuring it fills every cavity for a flawless part.
03

Curing for Quality

During curing, the material solidifies, acquiring the intended shape and unmatched quality.
04

Careful Demolding and Refinement

After curing, we expertly demold the part, then apply meticulous finishing touches for a refined, high-quality product.

More Questions

Urethane casting is ideal for low-volume production and allows more flexibility in material properties. Injection molding is more suitable for high-volume production with higher upfront tooling costs but faster per-part production.

We use durable metal molds for urethane casting, which are ideal for larger production runs. Depending on the resin type and part complexity, each mold can produce hundreds to thousands of high-quality parts, ensuring consistent performance and efficiency for batch production.

Depending on the complexity and quantity, lead times usually range from 3 days to 2 weeks for prototypes, and up to a few weeks for small production batches.
