Advantages of Silicone Overmolding for Medical Products

In the realm of medical technology, where stringent hygiene and mechanical standards are paramount, we've developed a series of silicone-overmolded system solutions. These solutions are tailored to meet the unique demands of medical applications, ensuring they adhere to rigorous cleanliness and durability requirements. Thanks to their non-adhesive surface and other features, they are easily cleaned, capable of withstanding steam sterilization, flexible, resistant to extreme temperatures, and compliant with DIN EN ISO 10993-5 standards. This renders them ideal for maintaining hygiene and resilience in everyday medical practices.

Biocompatibility

Non-toxic and harmless: Medical silicone materials are non-toxic and harmless to the human body, and are suitable for medical devices and implants that come into contact with the human body for a long time.
Hypoallergenic: Silicone materials do not cause allergic reactions and are suitable for use in sensitive people.

High and low temperature resistance

Wide temperature range: Medical silicone can maintain stable physical and chemical properties under extreme temperature conditions and can be used normally from -50°C to +250°C.
High temperature sterilization: Medical silicone products can withstand high temperature sterilization, such as high pressure sterilization, to ensure the sterility of the product.

Flexibility and elasticity

Highly flexible: Silicone has excellent flexibility and elasticity, can adapt to complex shapes and structures, and is not easy to deform.
Comfort: Due to its softness, silicone products are more comfortable when in contact with the human body, reducing friction and irritation.

Chemical stability

Corrosion resistance: Silicone is highly resistant to corrosion from many chemicals and can remain stable for a long time.
Anti-oxidation: Silicone is not easily oxidized and can maintain its performance under various environmental conditions.

Customized Silicone Solutions for the Medical Device Industry

We provide a full range of customized services from concept design to mass production, developing exclusive silicone solutions for different medical devices and application scenarios. Our technical team works closely with customers to ensure that each customized product meets the strict standards and specific needs of the medical industry.

Wearing comfort

Pain point: Long-term wearing of medical bracelets may cause skin discomfort or allergic reactions, especially in sensitive people.
Solution: We use medical-grade high-purity silicone to ensure that the bracelet is soft and fits the skin, has excellent breathability and hypoallergenic properties, so that users can feel comfortable even if they wear it for a long time.

Data transmission stability

Pain point: The data transmission performance of traditional medical bracelets is unstable, which affects the monitoring effect.
Solution: Our silicone + FPC solution combines flexible silicone materials and high-performance FPC (flexible printed circuit board) to ensure the stability and reliability of data transmission, while supporting complex functional integration and improving the overall performance of medical equipment.

Waterproof and dustproof performance

Pain point: Medical bracelets are easily exposed to water and dust during daily use, causing damage to electronic components.
Solution: Our customized bracelets use an integrated silicone coating design to ensure that the bracelets have excellent waterproof and dustproof performance, protect the internal electronic components from damage, and extend the service life of the bracelets.

Multifunctional integration

Pain point: Users need bracelets with multiple functions, but traditional bracelets have large design limitations.
Solution: Our silicone + FPC customized solution supports the integration of multiple sensors and functional modules, such as heart rate monitoring, step counting, body temperature detection, etc., providing users with a comprehensive health monitoring solution.

Appearance design and brand customization

Pain point: The appearance of the bracelets on the market is single, which makes it difficult to meet the needs of users for personalization and brand customization.
Solution: We provide a variety of customization services, including appearance design such as color, texture, size, etc., and can carry out brand logo and unique design according to customer requirements to meet the needs of different markets and customers.

Wide Application of Silicone Products in Medical Devices

Silicone medical products production process


1.Material selection and formula development
Based on the purpose and requirements of the product, select suitable silicone materials and develop formulas to ensure that silicone products have good biocompatibility, mechanical properties and chemical stability.

2. Mold design and manufacturing
After a deep understanding of customer needs, our engineering team will design the mold to ensure the dimensional accuracy and production efficiency of the product. Then the mold is manufactured through technologies such as CNC machining or EDM to meet the needs of high-precision production.

3. Silicone molding process
Depending on the complexity of the product and the requirements for mass production, select the appropriate molding process, such as liquid injection molding (LIM), compression molding, transfer molding or extrusion molding. During the molding process, silicone is formed into the desired shape and structure by heating and pressurizing.

4. Post-processing and surface treatment
After molding, products usually need post-processing, such as removing flash, polishing, surface coating or gluing, etc., to improve the functionality and appearance quality of the product. At the same time, some products also need secondary vulcanization to improve their performance and stability.

5. Quality Control and Testing
Throughout the production process, we implement strict quality control measures to ensure that each product meets the high standards of the medical industry. Through a variety of testing methods such as sterility testing, biocompatibility testing, dimensional testing, and mechanical performance testing, the safety and reliability of the final product are guaranteed.

6. Packaging and Delivery
In order to ensure the safety of the product during transportation and storage, we use a clean packaging solution that meets medical industry standards. After the product passes the final inspection, it will be packaged and delivered according to customer requirements.
