Introduction
Medical injection moulds are specialized molds used in the injection molding process to produce medical devices and components. The injection molding process involves injecting molten plastic or other materials into a precisely designed mold cavity under high pressure to form a specific shape.
Features
High Precision
Medical injection moulds use five-axis CNC machining and EDM precision molding technology, and the tolerance of key components can be controlled within the range of ±0.005mm, which is better than the industry standard of ±0.02mm. Secondly, the closed-loop temperature control system (accuracy ±0.3℃) ensures the stability of the molding process, so that the weight fluctuation of micro-structure components such as insulin pen cartridges and infusion connectors is less than 0.5%, meeting the ISO 20417 medical device production specification requirements.
Aseptic molding design
Our mold cavity surface is mirror polished (Ra≤0.1μm) and plasma chromized, and with a fully enclosed ejection system, the surface bacteria attachment of the mold is less than 5CFU/cm² after 72 hours of continuous production.
FAQ
Q: What are medical injection moulds?
A: Medical injection moulds are molds used to produce medical devices and components through the injection molding process. These molds are designed with precision and must meet strict safety, regulatory, and quality standards due to the critical nature of the medical industry.
Q: What materials are used in medical injection moulds?
A: Medical injection moulds typically use biocompatible materials such as medical-grade polypropylene (PP), polycarbonate (PC), polyethylene (PE), and medical-grade PVC. These materials are chosen for their safety, strength, and ability to withstand sterilization methods.
Q: Why is precision important in medical injection moulds?
A: Precision is crucial in medical injection moulds because medical devices often require tight tolerances to ensure proper functionality and safety. Even small deviations in size or shape can result in product failure or harm to patients, so accuracy is paramount.
Q: How are medical injection moulds sterilized?
A: Medical injection moulds and their products are designed to withstand various sterilization methods, including autoclaving (high-pressure steam), chemical sterilization, and gamma radiation. Materials used for molding must maintain their structural integrity and performance after sterilization.
Q: What are the advantages of using injection moulding for medical products?
A: Injection moulding offers several advantages, including high precision, fast production rates, the ability to create complex shapes, and the option to use a wide variety of materials. It is especially useful for producing large volumes of identical parts with consistent quality.
Q: What types of medical products are made using injection moulding?
A: A variety of medical products are made using injection moulding, including syringes, IV components, diagnostic devices, surgical tools, drug delivery systems, and implantable devices. These products require precise manufacturing to ensure functionality and safety.
Q: What is the lifespan of medical injection moulds?
A: The lifespan of medical injection moulds depends on factors such as material quality, design, and production volume. High-quality moulds made from durable materials like hardened steel can last for millions of cycles, significantly reducing the cost per part over time.
Q: How does regulatory compliance impact medical injection moulds?
A: Medical injection moulds must comply with strict regulatory standards such as FDA (Food and Drug Administration) regulations and ISO 13485 (quality management for medical devices). This ensures that products manufactured using these moulds are safe for use in medical applications.
Q: How are medical injection moulds designed?
A: Medical injection moulds are designed using advanced CAD (Computer-Aided Design) software to ensure high precision. The design process involves careful consideration of material flow, cooling time, and the need for complex features like undercuts or threads, all of which must be optimized for efficient production.
