Fast Production Vacuum Casting Prototype Smooth The Affordable Way To Create Production Parts

What Is Vacuum Casting?

Polyurethane vacuum casting is a specialized technique for making high-fidelity copies of master patterns using inexpensive silicone molds and pourable casting resins. Copies made in this way demonstrate the same quality as plastic injection molded parts while taking only a fraction of the time and expense to produce.

Advantages Of Vacuum Casting

Low cost for molds

Molds can be made in a few days

Many types of polyurethane resins are available for casting, including overmolding

Cast copies are highly accurate with excellent surface texture

Molds are durable for 20 or more copies

Perfect for engineering models, samples, rapid prototypes, bridge to production

Tolerance of Vacuum Casting

Material of Vacuum Casting

Vacuum casting offers a wide range of material options, including various polyurethane (PU) and epoxy resins. These materials can simulate the properties of different thermoplastics, elastomers, and even rigid or flexible rubbers. Material selection can be tailored to meet specific requirements such as mechanical strength, flexibility, transparency, or heat resistance.

Functional Prototyping: Vacuum casting allows for the production of functional prototypes that closely mimic the performance of the final product. Parts can be manufactured with similar mechanical properties, such as strength, flexibility, and impact resistance, enabling testing and validation before investing in full-scale production.

Reduced Design Constraints: Vacuum casting can accommodate complex geometries, thin walls, and intricate details that may be challenging or expensive to achieve through traditional manufacturing methods. This flexibility in design allows for greater creativity and innovation in product development.

Overmolding Capabilities: Vacuum casting can also facilitate overmolding, where multiple materials are combined to create parts with different properties or layered structures. This technique is useful for adding soft-touch grips, gaskets, or multi-colored features to the final product.

Confidentiality and Intellectual Property Protection: Vacuum casting services often prioritize confidentiality and can help protect sensitive design information. This is especially crucial during the prototyping or pre-production stages when maintaining the secrecy of new product designs is essential.

What Separates Barana Rapid’s Inspection Processes from the Rest?

Careful measurement, inspection and testing are necessary to ensure the conformance of your parts. We perform multiple inspections at every step of the product development journey, from incoming material verification to final 3D scanning. You will receive complete digital files and Certificates of Compliance so you can meet your own regulatory and performance goals.

An International Team with Unparalleled Experience

Quality inspection relies not only upon using advanced digital equipment but also having highly trained personnel with years of experience. As parts become more complex and tolerances more demanding for advanced applications, precision measurements conducted by professionals are the only way to ensure perfection.

Inspections and Review for Every Stage of Production

To ensure quality from start to finish, Barana Rapid provides the following inspection and review services:

Extensive incoming materials verification

Design for manufacturing reviews for all quotes provided

Contract reviews upon receipt of POs

First article and in-process inspections

Final inspections and testing with reports and certifications as required

Since 2015, our expertise in the prototyping and production industry has aided both start-ups and established brands in crafting prototypes and products that stand out in the global market. Our commitment to quality and precision is reflected in our advanced machinery and the dedicated team of professionals who work diligently to deliver your products on time. We offer rapid prototyping services at competitive prices, ensuring you receive parts with exceptional precision through cutting-edge manufacturing processes such as CNC machining, 3D printing, vacuum casting, and sheet metal fabrication—all within short lead times.

With precision CNC machining services, Barana Rapid is your ideal partner to create precision machined prototypes and parts. Our standard CNC machining tolerances for metals is ISO 2768-f and for plastics is ISO 2768-m. We can also achieve special tolerances as long as you indicate your requirements for your drawing.

We also provide low-cost manufacturing of high-quality plastic parts. Our vacuum casting services offer short-cycle solutions for creating high-quality prototypes and low-volume production parts. Vacuum casting, or urethane casting, is a method that utilizes a silicone mold and a 3D printed master to produce vacuum-cast parts with consistent performance and production-grade quality. This technology does not require a costly initial investment, enables flexible and economical production, and hardens thermoplastic polyurethane in silicone or epoxy molds. The outcome is a vacuum-cast part that retains the shape of the original master model. The final dimensions of a vacuum-cast part are determined by the master model, the part's geometry, and the selected material.

Our sheet metal fabrication factory offers top-tier custom services, leveraging extensive capabilities in sheet metal stamping, cutting, bending, welding, precision CNC machining, and assembly to deliver superior quality parts. NOBLE's manufacturers employ cutting-edge technology and skilled engineers to guarantee sheet metal parts of unmatched quality, precision, and reliable performance.

Barana Rapid boasts over a decade of expertise in small-batch manufacturing, backed by a stellar team and robust suppliers to fulfill all your small-batch production requirements. Leveraging our extensive experience in small batch molding and our team of exceptional engineers, we are committed to efficiently managing all your small batch machining projects. Our strong supply chain and state-of-the-art equipment for various manufacturing technologies enable us to execute with precision. We guarantee that our wholesale prices will be competitive, we will uphold stringent quality standards, aid clients in design optimization, select the most suitable CNC processing techniques, minimize costs, and facilitate swift mass production. This ensures the delivery of cost-effective and high-precision products to you.

Regardless of the manufacturing process employed, high-quality surface finishing services can enhance both the appearance and functionality of your components. We provide a range of superior metal, composite, and plastic surface finishing services to realize the prototype or component you envision.
