A specialized urethane casting service is the perfect way to develop prototypes and high-quality parts at a low cost. Unlike injection molding, a streamlined process can produce production-grade parts in low volumes. Using the process, you can create a prototype or model for your client presentation. This versatile material is also ideal for small-scale, limited-production runs of rubber or rigid plastic parts.
The process begins with a master pattern, which can be created through CNC machining or additive manufacturing. Then, a quick-curing liquid silicone is poured into the mold. The silicone sets up the mold, which forms the cavity. The master pattern is then removed from the mold. The surface finish of the parts is molded by hand using high-quality silicon. This process requires a great deal of time and skill.
One of the biggest advantages of a urethane casting service is that it can produce prototype parts that are incredibly inexpensive and offer multiple finishes. In addition to being cheap, urethane molds can be obtained within a day or two, whereas silicone molds can only make 20 or less castings. Another advantage is the fact that urethane molds are easy to obtain globally, allowing for more intricate design options.
A urethane casting service can also produce large-scale parts with varying tolerances. The minimum size for a polyurethane casting is 1000 cubic inches. Some larger pieces may require separate inspections, but a urethane mold can produce prototype parts that are over 30 inches long. It can even be a million cubic inches. You can use this service for large-scale projects. However, if you do not have the right mold, you can try a 3D printing service that offers a low-cost, high-quality solution.
A polyurethane casting service is a great way to create prototypes and test parts. The process starts by pouring liquid polyurethane or silicone into a silicone mold. The mold is then placed in a vacuum or pressure chamber. The pressure chamber enhances the mechanical properties of the resulting part. Afterwards, the mold is removed and the new part is removed. The part is then cleaned to remove any excess flash.
A urethane casting service can also create hard and soft prototypes of parts. The hard prototype is made from liquid polyurethane and is cast into a mold. The mold is then placed in a vacuum or pressure chamber. This enhances the mechanical properties of the part. Once the mold is finished, the parts are separated and the mold is cleaned. In addition to this, the prototype is then ready to be painted.
A urethane casting service can produce a variety of shapes and sizes. It is the perfect option for prototyping. Compared to 3D printing, a urethane casting service can save time and money. It can also produce quality, low-volume plastic parts without the need for costly tooling. The urethane casting process is fast and affordable, which makes it a popular choice for many companies.
A urethane casting service creates the exact prototype from the mold. Its surface finish is smooth and the mold is designed with various properties. Its strength and durability are unmatched by any other material. It can be purchased globally, and it costs very little, making it an ideal solution for prototypes. Because it allows for virtually limitless complexity, urethane castings are ideal for prototyping elastomeric parts.
