Description
Vacuum casting, named siicon molding,is a reat methodto recreate quickly forlow-wolume production. firstly we make a master by CNC machining or3D pintino,then pouing a siicormold to create reproductions copies. lt's a fast and economical way for the small batches 10-100PCS. Generally, a mold can reproduce 10-30 pieces copies.
There are also many materials are used for Vacuum Casting: silicon, rubber, PU(PU8400, PU8150,PU8260...), PX Series(PX100, PX210, PX521...）
High-Fidelity Silicone Molding Technology
Immicron offers a premium vacuum casting service designed to reproduce complex designs with exceptional accuracy. Our process utilizes advanced silicone molding techniques to replicate every detail of the master pattern, from intricate textures to precise geometric features. By operating under a strictly controlled vacuum environment, we ensure that the liquid resin fills the mold cavity completely, eliminating air pockets and voids. This results in vacuum cast parts that possess a dense, uniform structure and a flawless surface finish. Whether your project requires high-gloss aesthetics or specific surface graining, our manufacturing capabilities ensure that the physical parts reflect your digital design intent perfectly, providing a reliable solution for producing high-quality components without the long lead times of hard tooling.
Engineering-Grade Material Performance
Our manufacturing facility provides access to a diverse range of Polyurethane (PU) resins that simulate the properties of production thermoplastics. Through our vacuum casting services, we produce parts that mimic the mechanical characteristics of ABS, Polycarbonate (PC), Polypropylene (PP), and Acrylic (PMMA). We also offer elastomeric resins for creating rubber-like parts with varying Shore hardness levels, suitable for seals and gaskets. For projects requiring specific aesthetic or functional traits, we can incorporate pigments to achieve precise color matching or UV stability. While the core material is polymer-based, our advanced finishing techniques can modify the appearance to resemble vacuum casting metal components, allowing engineers to verify the visual impact of metallic designs using lightweight, cost-effective resin materials.
Rapid Manufacturing and Design Verification
Immicron’s approach to vacuum casting focuses on speed and flexibility in manufacturing. This process allows for the rapid creation of functional parts that are ready for rigorous testing and assembly validation. Unlike traditional vacuum die casting which involves complex metal tooling, our silicone tooling process is agile and adaptable, enabling quicker iterations. This makes it an ideal choice for validating complex assemblies, conducting thermal and drop tests, or producing end-use parts for market entry. By delivering components that match the performance standards of mass-produced items, we help clients accelerate their product development timelines and ensure their designs are robust and market-ready.
The advantages of Vacuum casting:
1.Suitable for low volume production
2. Kinds of materials
3. Matching different colour
Complex Geometry Realization
One of the distinct strengths of Immicron’s vacuum casting is its ability to handle complex geometries that are challenging for rigid molds. The flexibility of silicone tooling allows for the production of parts with undercuts, negative drafts, and intricate details without the need for complicated sliders or lifters. This capability gives designers greater freedom to innovate without being constrained by traditional mold limitations. Our technicians are skilled in optimizing mold strategies to ensure that even the most complex vacuum cast parts are demolded without damage, maintaining the integrity of fine features and ensuring consistent dimensions across every unit produced.
Integrated Overmolding Capabilities
Immicron excels in producing multi-material components through advanced overmolding techniques. Our vacuum casting service allows for the integration of different materials, such as bonding a soft rubber grip onto a rigid plastic housing, in a single cohesive unit. This process creates strong chemical and mechanical bonds between the materials, ensuring durability and performance. This capability is essential for manufacturing ergonomic handheld devices, protective casings, and functional buttons. By simulating the actual production assembly method, we provide vacuum cast parts that not only look like the final product but also function exactly as intended in real-world environments.
Superior Surface Finishing Options
We understand that surface quality is paramount. Immicron provides a comprehensive suite of post-processing options to enhance the final appearance of your parts. From standard polishing and painting to advanced texturing, we ensure your components meet the highest cosmetic standards. For clients seeking the look of metal without the weight, our finishing team can apply metallic coatings that simulate the appearance of vacuum casting metal or anodized aluminum. This attention to detail ensures that the parts are indistinguishable from final production units, making them suitable for high-stakes presentations, marketing photography, and functional end-use applications.
