Urethane Casting Service

Urethane casting is a process where urethane resins are poured into the silicone rubber molds to produce the plastic parts in low-volume productions. LEADRP provides urethane casting service to improve the speed and ability to cope with your prototyping and low-volume production applications.

Urethane Casting Tecnical Specifications

Standard Lead TimeUp to 10 copies within 14 days
Standard Tolerance±0.3% (with a lower limit on ± 0.3 mm on dimensions smaller than 100 mm)
Minimum Wall ThicknessTo ensure that the mold is filled properly, a wall thickness of at least 0.75 mm is necessary. For best results, we recommend a wall thickness of at least 1.5 mm
Maximum Part DimensionsThe size of the mold is limited by the dimensions of the vacuum chamber (1900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters)
Typical QuantitiesUp to 25 copies per mold (depending on the mold’s complexity and the casting materials)
Surface StructureHigh-quality surface finish comparable to injection molding

What is Urethane Casting and How Does it Work

Urethane Casting is a process of making plastic parts. Urethane casting is similar to injection molding, master patterns can be produced by CNC machining or 3D printing. The material used in the process is thermoplastic polyurethane. It is a material that has properties similar to rubber, flexible and feels like silicone.

The urethane is typically poured into a silicone(RTV silicone) or epoxy mold, where it cures (hardens). Then create polyurethane casting under vacuum, so urethane casting is also known as vacuum casting. The result is that the urethane casting part has the same shape as the original master model. Once the silicone mold is ready, polyurethane resin can be cast into it to get your desired parts.

Urethane casting makes it possible to cast high quality parts from more affordable silicone tooling. Urethane casting is an excellent choice for creating low-volume production runs from 50 to 10,000+ pieces.

Surface Finish Options for Urethane Casting Parts

Surface finish is applied to parts after they have been machined to create a unique surface layer to meet the hardness, chemical resistance, and appearance requirements of the products. It depends on material properties and the application of the part. LEADRP offers the following finishing options for injection molded parts services:
