Urethane casting is a fast and cost-effective method of producing small series from a silicone mold. A silicone mold is made with the help of a prototype which serves as the basis for the duplication process of the original piece. Thanks to the flexibility of the silicone, complex intermeshing geometries can be achieved without demoulding problems. The base material used for the reproductions is a liquid polyurethane resin which with the use of additives can simulate the properties of a wide variety of plastics. Between 15 and 30 parts can be produced depending on the requirements of the material and surface finish. This method is ideal for the production of small batches and prototypes in which the production of expensive injection molding tools is not feasible

Vacuum casting technology offers a wide variety of materials to facilitate the creation of cast urethane parts, typically for functional test, pre-production evaluation and low volume production. Cast auto urethane parts are quick and inexpensive without the need to invest any metal tooling when quantities are only dozens of short runs, and can be delivered within weeks in most instances. Standard lead time Up to 10 copies within 15 working days Standard accuracy ±0.3% (with lower limit on ±0.3 mm on dimensions smaller than 100 mm) Minimum wall thickness To 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 dimensions The 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 quantities Up to 25 copies per mold (depending on the mold's complexity and the casting materials) Surface structure High-quality surface finish comparable to injection molding. Advantages of Silicone Auto parts Vacuum Casting : Great for low volumes Self-coloured parts Low upfront investment Production like parts Massive range of materials Rubber like parts and over molds
'Sheet metal is metal formed by an industrial process into thin and flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate. At RPWORLD, our sheet metal fabrication service is designed for rapid prototyping, end-use production and assemblies.
Life casting liquid silicone rubber is kind of two-component platinum catalyst liquid silicone. The product is colorless or skin-colored oily liquid, and can be very soft and elastomeric after vulcanization.
