Reliable Urethane Casting Services Provider from China

Robotika has specialized in urethane casting for over a decade years, which stands itself out for combining in-house silicone mold design, diverse polyurethane material options, and premium finishing processes. We specialize in reproducing complex geometries, undercuts, and fine surface textures that closely simulate injection-molded parts, but at a fraction of the cost and lead time. We help customers accelerate product development by providing detailed design feedback, material selection guidance, and surface finishing options to meet both functional and aesthetic requirements. Whether you need a prototype to validate your design, bridge production before mass manufacturing, or customized low-volume parts, we ensure accuracy, consistency, and reduced lead times.

Our capabilities support across automotive, medical devices, consumer electronics, robotics, and industrial equipment sectors. We produce thousands of custom cast and molded parts annually, supporting startups and established enterprises alike with reliable supply and professional engineering support.

Our Urethane Casting Capabilities

Robotika provides a comprehensive range of urethane casting solutions, including silicone mold fabrication, material versatility, precision surface finishing, and low-volume & bridge production. We work with a wide selection of polyurethane resins—ranging from rigid, impact-resistant plastics to flexible, rubber-like materials, as well as clear and tinted formulation. To enhance part quality and functionality, we offer multiple surface finishing options, such as sanding, polishing, painting, and texturing, delivering cosmetic-grade prototypes and production-ready components. With strict dimensional control, our urethane casted parts achieve tolerances typically around ±0.2 mm/100 mm, depending on part size and geometry. Our urethane casting parts meet both functional performance and presentation-level aesthetics, making them an ideal solution for prototyping, product validation, and small-batch end-use production.

Urethane Casting Materials

ABS-like Polyurethane

ABS-like polyurethane is a versatile choice for urethane casting due to its excellent mechanical strength, toughness, and impact resistance. It closely mimics injection-molded ABS, making it suitable for housings, dashboards, and consumer product prototypes.

Lead Time: As fast as 3 days
Finishes: Raw, painted, textured, polished

PP-like Polyurethane

PP-like polyurethane provides flexibility, fatigue resistance, and good chemical tolerance, making it ideal for urethane casting of snap-fit parts, covers, and lightweight prototypes. It is widely used in packaging, automotive interiors, and household product models.

Lead Time: As fast as 3–5 days
Finishes: Raw, painted, textured

PE-like Polyurethane

PE-like polyurethane is lightweight, tough, and highly resistant to chemicals, which makes it suitable for urethane casting of containers, fluid-handling parts, and low-cost industrial components. It is commonly used for storage boxes, caps, and protective housings.

Lead Time: As fast as 4 days
Finishes: Raw, painted, polished

PMMA (Acrylic)-like Polyurethane

PMMA-like polyurethane offers excellent transparency, gloss, and weather resistance, replicating the clarity of acrylic in urethane casting. It is ideal for lenses, light covers, and display parts where high aesthetics and optical properties are required.

Lead Time: As fast as 3–4 days
Finishes: Raw, polished, painted

Nylon (PA)-like Polyurethane

Nylon-like polyurethane delivers high strength, toughness, and wear resistance, making it suitable for urethane casting of gears, bushings, and structural mechanical parts. It closely simulates nylon properties for functional testing and end-use prototypes.

Lead Time: As fast as 3–5 days
Finishes: Raw, polished, painted

PC-like polyurethane

PC-like polyurethane offers toughness, heat resistance, and high impact strength, ideal for urethane casting of safety housings, transparent covers, and engineering components. It is often used for automotive and electronics prototypes requiring durability.

Lead Time: As fast as 3–4 days
Finishes: Raw, polished, painted, textured

Rubber-like polyurethane

Rubber-like polyurethane is flexible, elastic, and durable, making it perfect for seals, gaskets, ergonomic grips, and cushioning components. It allows urethane casting to simulate rubber products for both prototypes and low-volume functional use.

Lead Time: As fast as 3 days
Finishes: Raw, textured, painted

Flame-retardant polyurethane

Flame-retardant polyurethane formulations meet UL94 standards, ensuring safety in electronics, aerospace, and medical device prototypes. They are widely applied where fire safety and compliance are required alongside mechanical performance.

Lead Time: As fast as 4–6 days
Finishes: Raw, painted, polished
