Medical devices require extremely high precision and reliability, especially for components that come into direct contact with patients or are used in critical healthcare applications. Vacuum casting is an essential method for manufacturing high-precision plastic parts for medical devices, such as injection molds, casings, and enclosures.

Materials such as Polypropylene (PP) and Polycarbonate (PC) are commonly used in the medical industry due to their excellent mechanical properties, biocompatibility, and resistance to sterilization processes.

• Polypropylene (PP): Chemical resistance, low density, and biocompatibility, ideal for syringes, medical containers, and diagnostic equipment. Withstands sterilization procedures like autoclaving.
• Polycarbonate (PC): Strong, durable material with excellent optical clarity, suitable for medical device enclosures, covers, and transparent components. High heat resistance crucial for heat sterilization methods.

The process begins by creating a master model (3D-printed prototype or existing part) used to create a silicone mold. Liquid resin is injected into the mold under vacuum, ensuring complete cavity filling for parts with smooth surfaces, excellent dimensional accuracy, and high detail.

• Cost-effective production of high-quality, low-volume plastic parts comparable to injection molding
• Ideal for form, fit, and function tests during design stages
• Suitable for marketing, field user testing, and product design verification
• Wide range of materials available for different temperature requirements, surface textures, hardness, etc.
• Can produce fully opaque, translucent, or completely transparent parts
• Can create high-quality wax masters for investment casting of intricate features

Polyurethane is a versatile polymer material with excellent mechanical properties and plasticity. After nearly eighty years of development, it has wide applications in textiles, construction, aviation, shipping, transportation, medicine, electronics, and more.

• Flexible Polyurethane: Linear structure with thermoplasticity, better stability and chemical resistance than PVC foams. Used as packaging, sound insulation, and filtration materials.
• Rigid Polyurethane: Lightweight with superior thermal insulation, used in construction, automotive, and aviation industries.
• Polyurethane Elastomer: Performance between plastic and rubber, used in shoe and medical industries.
• Also used in adhesives, coatings, synthetic leather, etc.
