What Is Urethane Casting?

Urethane casting is a process that utilizes a two-part liquid urethane resin to produce production-quality plastic parts through a silicone mold. It creates highly precise replicas of a master pattern and is a cost-effective and fast-turnaround method for creating rapid plastic prototypes.

Advantages Of Urethane Casting

Cost-Effective: Urethane casting is cheaper and faster than injection molding or 3D printing for producing high-quality plastic parts.
Low Upfront Investment: Unlike injection molding, which requires costly mold machining, silicone molds for urethane casting are affordable and easy to produce.
Ready-to-Use Parts: Urethane cast parts come out of the mold ready for use, eliminating extensive post-processing typically needed with 3D printing.
Versatile Applications: Ideal for high-quality prototypes or low-volume production of various plastic components, including rigid, flexible, clear, colored, or rubber-like materials.

Applications of Urethane Casting

Urethane casting is widely used across industries like automotive, aerospace, medical, and consumer goods, particularly when intricate parts with complex geometries require low-volume precise replication such as Enclosures, Electronic device casings and displays.

Urethane Casting Process

Kusla’s urethane casting service is ideal for low-volume manufacturing parts quickly for functional and cosmetic testing.

Urethane Casting Materials

Polyurethane is a popular thermoset material known for its strength, durability, and versatility. It can replicate the properties of many common thermoplastics; for instance, a stiff urethane part resembles polycarbonate, while a flexible one mimics polypropylene. We categorize our urethane materials to help you quickly choose the best option for your project. Below is a list of material categories with technical examples for selecting polyurethanes.

Type of Material		Comment	Color	Hardness	Material reference
urethane casting resin(Rigid)	ABS-Like	ABS-Like is a general-purpose polyurethane plastic that simulates ABS thermoplastic. This material is a great choice for most product enclosures.	All colors	Shore D 76-80	BJB TC-852
	Acrylic-Like	Acrylic-Like is a stiff, transparent polyurethane plastic that simulates acrylic (PMMA). This material is great for see-through applications such as light pipes.	Transparent	shore D 80	Polytek Poly-Optic? 14 Series
	Polycarbonate-Like	A stiff, USP Class VI, high-performance urethane with high impact strength and a HDT of 190°F (88°C).	Transparent	shore D 82-86	BJB TC-854
urethane casting Rubber(Elastomers)	Rubber-Like Polyurethane	a polyurethane plastic that simulates all kinds of rubber-like materials such as TPE, TPU, and silicone rubber. This material is great for wearables, gaskets, and overmolds	All colors	20-95Shore A	BJB F-170
	Clear Rubber-Like Polyurethane	A colorless Shore A elastomer with a high elongation to break. Matte finish will give a frosted appearance, and higher gloss will increase its transparency.	Transparent	40-95 Shore A	BJB WC-565

FAQ

Most frequent questions and answers

What is the lead time for getting the urethane casting prototypes?

It depends on the volume and complexity of the parts. Production usually takes three business days to a week, and shipping by DHL express takes 3 days.

How much does urethane casting cost?

The price range for the urethane casting prototypes is $5 to $200. Each silicone mold can make up to 25 copies; the more you make, the cheaper the piece price.

Can you cast silicone in a urethane mold?

Yes, we can make silicone parts with urethane casting process.

What is the difference between urethane casting and injection molding?

Urethane molding uses polyurethanes to simulate an injection mold grade production plastic, whereas injection molding uses the actual production plastics.

How thick should a wall be for urethane casting?

Walls as thin as 0.020” (0.5mm) for some small components and 0.040” (1mm) thickness for large parts.

Can you paint on the urethane casting prototype?

Yes, Spray paint for Matte, bright, sand, and smooth finish is available for urethane casting prototypes.

What are the reasons for selecting urethane casting instead of injection molding?

When considering production methods, it is crucial to choose between urethane casting and injection molding. Urethane casting is particularly beneficial for low-volume production runs.
For quantities as low as 50 pieces, urethane casting offers cost-effective solutions without the hefty upfront tooling expenses associated with injection molding. Customers prefer urethane casting as a preliminary step to refine their designs before committing to the more expensive injection molding process.
