Material Overview Vacuum Casting

Product catalog summary

Company Overview: SLM Solutions GmbH specializes in rapid manufacturing systems, focusing on vacuum casting, metal casting, and laser melting. With over 50 years of experience, they provide solutions for prototype and small series production using materials like PU-resins, vacuum casting silicones, and nylon components.

Vacuum Casting Process: The vacuum casting system is noted for its precision and user-friendliness, enabling the production of 30-50 prototypes within 2-3 days, thus reducing time and costs compared to traditional methods. It supports various consumables and offers optional modules for nylon casting.

Material Specifications: Detailed specifications are provided for materials used in vacuum casting, including hardness, flexural modulus, tensile strength, and heat resistance. These FDA-approved materials for dry food use offer diverse mechanical properties and colors for different applications.

Technical Data: Extensive technical data tables are included, detailing properties such as hardness, flexural modulus, tensile strength, heat detection temperature, glass transition temperature, elongation at break, tear strength, yield strength, impact resistance, thermal conductivity, density, viscosity, mixing ratios, pot life, curing time, demoulding time, and shrinkage rates.

Recommendations: Users are advised to refer to the company's data sheets for detailed product information and handling instructions. The document highlights the importance of selecting appropriate materials and process parameters for desired outcomes in prototype and small series production.

Specifications: Detailed specifications for vacuum casting resins and silicone rubbers are provided, including mixing ratios, pot life, curing time, demoulding time, shrinkage, and thermal properties. The use of correct release agents and sealers for different materials is emphasized.

Procedures: Instructions for vacuum casting processes are outlined, including the preparation of silicone rubbers and the use of modifiers and fillers for long mould life and dimensional stability. Applications of vacuum casting machines include casting plastic prototypes, metal parts, and ceramic components.

Standards and Recommendations: The document references international standards (ISO, ASTM, DIN, BS) for testing properties like tensile strength, flexural strength, and thermal conductivity. It emphasizes using specific catalysts to adjust the Shore A hardness of silicone rubbers.

Key Data from Tables: Mixing ratios range from 100:10 to 100:500 depending on the resin type. Pot life varies, with some resins having a pot life of up to 3600 seconds. Curing times are generally around 1440 minutes at 23°C. Shrinkage percentages are provided according to wall thickness, ranging from 0.1% to 2.5%. Thermal properties such as heat deflection temperature and glass transition temperature are specified for different materials.

Critical Information: The document stresses the importance of post-curing to enhance heat resistance. It provides a comprehensive list of accessories and pigments compatible with vacuum casting resins. Recommendations for release agents and sealers are provided to ensure optimal casting results.

Conclusion: This technical document serves as a comprehensive guide for professionals involved in vacuum casting, offering detailed specifications, procedures, and recommendations to ensure high-quality casting results.
