Custom Silicone Rubber Molding Services
Plasticpartsmfg provides custom silicone rubber molding services for product developers, engineering teams, and manufacturers. Based in Shenzhen, China, we specialize in translating complex CAD designs into functional silicone components, supporting projects ranging from rapid prototyping and soft-touch product testing to low-volume production.
We handle the entire process—from master model creation and mold development to material selection, molding, and secondary finishing. Whether you need seals, gaskets, protective housings, or flexible elastomeric parts, our team delivers parts that meet your specific hardness, dimensional, and material requirements.
Manufacturing Capabilities
We support both RTV silicone and various silicone elastomers, ensuring we can match the physical properties required for your application. Our facility is equipped to handle projects from a single prototype to batches of several thousand units.

Why Choose Silicone Molding?
Silicone molding is the preferred method for components that require flexibility, high thermal stability, or chemical resistance. Unlike rigid plastics, molded silicone offers distinct advantages for specific functional requirements.
Complex Geometry Reproduction
Our molding process captures fine surface details and intricate internal features, which is essential for medical devices, consumer electronics, and industrial seals.
Material Versatility
With a hardness range of Shore A 10–80, we can produce parts ranging from soft, pliable gaskets to firm, shock-absorbing bumpers.
Rapid Iteration
For product development teams, we offer flexible tooling solutions that allow for fast design changes and prototype testing before moving to larger production runs.
Customization
We provide color-matching services to ensure your components align with your brand identity or functional requirements, such as high-visibility safety parts.
Common Applications
We manufacture components for a wide range of industries where material performance and durability are critical. Select an application to review functional requirements.
Seals and Gaskets
Precision-molded components for fluid management, vacuum systems, and enclosure sealing requiring reliable compression recovery.
Soft-Touch Components
Grips, handles, and ergonomic buttons for consumer devices and industrial handheld equipment, providing tactile comfort and resistance.
Protective Covers
Flexible housings designed to shield sensitive electronic devices, sensors, and laboratory test instruments against shock and environmental dust.
Medical & Lab Equipment
Non-reactive, chemically stable, durable components suitable for medical diagnostic device housings, fluid connectors, or labware.
Vibration Dampening
Custom pads, isolators, and mechanical mounts engineered to absorb impact, reduce resonance, and minimize noise in motorized assemblies.
