Precision LSR Injection, Extrusion & Compression Moulding
Specialised techniques transforming liquid silicone rubber into precision-engineered components. We deliver reliable solutions for complex geometries and tight tolerances.
Our Capabilities
Highly Accurate Rubber Moulding with Tight Tolerances
Our advanced LSR injection moulding technology enables the production of highly precise and complex components while reducing cycle times by 15–30%. With dual extrusion technology, we deliver greater efficiency and versatility, while compression moulding is optimised for manufacturing larger parts and moderately curved parts. Through high accuracy moulding processes, we consistently achieve tight tolerances ranging from 0.08 mm to 0.15 mm, ensuring superior quality and reliability for every application.

Proven Results in Vital Implementations
Developing a Silicone Wound Care Patch
Silcotech engineered a reusable silicone patch designed to support skin recovery and reduce the appearance of hypertrophic and keloid scars. The patch is made with medical grade silicone to ensure comfort, durability, and safe for long durations. It is also registered with Malaysia Medical Devices (MDA # : GA7620221-71414)
Manufacturing Process
- Silicone Casting: High-grade medical silicone rubber is cast to achieve uniform softness, flexibility, and skin compatibility.
- Breathable Layer Integration: A precision lamination process bonds a breathable protective film, allowing moisture release while maintaining strong adhesion.
- Form and Adhesion Control: The gel layer is optimised to retain shape, remain stable, and provide consistent contact with the skin through repeated applications.
How the Patch Works
When applied to healed skin, the patch delivers continuous hydration and gentle pressure to help flatten raised scars. It is washable, reusable, and clinically aligned with medical device standards, demonstrating Silcotech’s capability in advanced silicone processing and wound care solutions.
Developing a Catheter-Deployable Cardiac Occluder
Silcotech collaborated on the development of a cardiac occluder designed for minimally invasive procedures to close defects in the heart. The device integrates a nitinol wire mesh with an ultra-thin silicone film, ensuring both structural stability and long-term biocompatibility.
Manufacturing Process
- Nitinol Wire Shaping: The nitinol wire is cut, laser-welded, and precision-formed into a double-disc structure for secure closure.
- Silicone Overmoulding: A 0.08 mm ±10% silicone film is overmoulded onto the wire mesh, reinforced with polyester fabric, to provide strength, elasticity, and biocompatibility.
- Delivery System: The device is engineered for catheter-based deployment, with a delivery mechanism that enables accurate placement and controlled release.
How the Occluder Works
The occluder is guided through a blood vessel—commonly from the groin—to the heart. Once in position, it expands to cover and seal the defect. Over time, tissue naturally grows around the device, creating a permanent closure without the need for open-heart surgery.
Silicone Potting for Wearable IoT Applications
Silcotech contributed to the development of a wearable IoT vest by engineering the silicone encapsulation process for the electronic modules. The focus was on creating protective housing that could withstand outdoor environments while maintaining comfort for long-term wear.
Manufacturing Process
- 3D Printed Moulding: A custom mould was 3D printed to hold the silicone potting material, ensuring precise form and consistent protection.
- Material Selection: Fifteen materials were sourced and evaluated. Through engineering-led testing, one was chosen for its balance of flexibility, durability, and weather resistance.
- Form and Electronics Integration: The electronic board was embedded within the silicone, safeguarding sensitive components without compromising performance.
- Module Assembly: Once encapsulated, the protected modules were stitched into the vest to enable seamless integration with textile layers.
Final Application
The silicone-potted modules enabled the IoT vest to remain comfortable in different climates and reliable during long hours of outdoor use. This project highlights Silcotech’s capability in silicone processing, material testing, and electronic protection for wearable technologies.
