Urethane Casting Service
Produce high-fidelity prototypes and low-volume production parts with InstaMFG’s urethane casting services, delivering components in as fast as 7 days. Our process utilizes silicone molds and polyurethane resins to replicate intricate designs with precision, ideal for functional testing and market validation.
Commonly Used Materials:
We offer a variety of polyurethane resins to suit different application needs:
Rigid Polyurethane – for durable, impact-resistant parts
Flexible Polyurethane – for components requiring elasticity
High-Temperature Polyurethane – suitable for parts exposed to elevated temperatures
Transparent Polyurethane – for clear or tinted parts
Flame-Retardant Polyurethane – for applications requiring fire resistance
These materials can be tailored to mimic the properties of production-grade plastics, providing versatility in prototyping and low-volume manufacturing
InstaMFG combines advanced mold design strategies with rapid tooling techniques to deliver production-quality molded parts in just 48 hours. Our high-speed workflow integrates precision-machined inserts, modular base systems, and digital tool path optimization to reduce lead times without compromising part accuracy. Each mold is engineered with high repeatability in mind, achieving tolerances up to ±0.01 mm and supporting a wide range of geometries. We ensure process reliability through closed-loop monitoring of fill behavior, cycle temperature, and part ejection. Additionally, material selection is supported by real-time resin conditioning and pre-processing, ensuring optimal performance for both functional and visual requirements.

Customization & Aesthetic Replication
Urethane casting offers extensive customization options to replicate the aesthetics of final products accurately. Through the use of master patterns and silicone molds, intricate surface textures and fine details can be faithfully reproduced. Additionally, a wide range of color options and finishes are available, allowing for the creation of parts that meet specific visual and tactile requirements. This level of customization ensures that prototypes not only function as intended but also provide a realistic representation of the final product's appearance.

Low-Volume Production in China
2026 Manufacturing S Why “Bridge Production” (50-500 units) is the secret weapon for hardware startups avoiding the “Death Valley” of high MOQ. Here is the classic hardware trap: You have validated your prototype (1-5 units). You aren’t ready for mass production (10,000+ units). You need 200 units for a pilot run or beta test. Most…
