Conditions of Medical Silicone Rubber Injection Molding

Medical silicone rubber injection molding is a crucial process in the healthcare industry, ensuring the production of precise and high-quality components used in medical devices. As a product development engineer, it's essential to understand the four critical conditions that impact the success of this process.

Material Selection:

The foundation of successful medical silicone rubber injection molding lies in choosing a suitable material. Medical-grade silicone rubber is known for its biocompatibility, chemical resistance, and flexibility. Ensuring the material meets stringent medical standards, such as USP Class VI or ISO 10993-1, is imperative. Furthermore, precise durometer ratings (typically ranging from 10 to 80) must be considered, depending on the specific application, as different hardness levels offer varying degrees of flexibility and durability.

Temperature and Pressure Control:

Precision is paramount in medical device manufacturing. Maintaining tight control over temperature and pressure is crucial during injection molding. Silicone rubber has a relatively low melting point, typically around 392°F (200°C), which makes it susceptible to variations. For consistent, high-precision results, precise temperature control within a range of ±1°F (±0.5°C) is essential. Similarly, injection pressure should be adjusted according to the mold's geometry and the silicone material's viscosity.

Injection Speed and Rate:

The correct injection speed and rate are fundamental to avoid defects such as air entrapment or flash. The viscosity of the silicone material can change with temperature, so it's essential to calibrate the injection speed to match the specific material's characteristics. In the medical industry, where precision is non-negotiable, using controlled low-pressure injection techniques is expected to minimize material waste and ensure consistent part quality.

Tooling and Mold Design:

The heart of the injection molding process is the mold design. It should be tailored to the specific medical component, considering factors like part geometry, wall thickness, and undercuts. Medical silicone rubber injection molding at Neway leverages advanced tooling and mold design techniques, such as multi-cavity molds and cold runner systems, to ensure efficient production while maintaining precision. Additionally, molds should be carefully maintained and inspected for any signs of wear or damage to avoid defects in the final product.

Benefits of Injection Molded Medical Connectors

Injection-molded silicone rubber medical connectors offer several significant medical device industry advantages. First and foremost, they excel in precision and consistency, with tight tolerances and high-quality surface finishes. For instance, they can achieve micron-level precision, which is essential for ensuring the reliability and functionality of medical equipment. This precision is crucial in applications like catheters, where any variation can impact patient safety. Such precision ensures that connectors fit securely and perform their intended functions, contributing to the overall efficacy of medical devices.


Moreover, injection-molded silicone rubber connectors are biocompatible and hypoallergenic, making them ideal for medical applications. These materials undergo rigorous testing to ensure they do not trigger adverse reactions in the human body. In critical medical procedures, such as surgery or implantable devices, the biocompatibility of connectors is paramount. Neway's expertise in providing high-precision injection molding services ensures these connectors meet strict industry standards.

Additionally, these connectors resist various environmental factors, including extreme temperatures, chemicals, and radiation. This resilience is invaluable in medical, where sterility and durability are paramount. Their resistance to harsh conditions ensures they remain effective throughout their intended use, providing a longer lifespan for medical devices. Neway's injection molding capabilities and a deep understanding of the medical industry position them as a reliable partner for producing such critical components, further underscoring the company's commitment to quality and precision.
