Siltech provides silicone rubber casting services for custom components ranging from small, intricate parts through to large-format gaskets and seals.
Silicone casting is particularly well suited to applications where part size, geometry, or tooling constraints make compression moulding impractical. The process allows for excellent material flow, consistent thickness, and accurate reproduction of complex shapes, making it ideal for large gaskets, custom seals, linings, and specialised industrial components.
We cast silicone rubber in a range of formulations and hardnesses to suit the intended application, including parts designed for food handling, processing equipment, and demanding industrial environments. Casting enables the production of parts that maintain flexibility, resilience, and dimensional stability, even at larger sizes.
Siltech works closely with customers to develop casting solutions that balance performance, durability, and cost, whether for prototypes, one-off components, or repeat production. Our in-house capability allows us to maintain tight control over material selection, processing, and finishing.
All silicone casting is carried out in New Zealand, with an emphasis on quality, repeatability, and confidentiality for customer designs.
Custom rubber components, manufactured to meet demanding mechanical, chemical, and environmental requirements.
Compression moulding of silicone rubber components in Shore A hardnesses from 30 to 70, suitable for food handling and industrial applications.
Durable nylon coatings engineered for wear resistance, impact protection, and long service life in demanding industrial environments.
Industrial PTFE and PFA coating services for food-contact and industrial applications, delivering reliable release performance, wear resistance, and long service life.
Whether you’re specifying silicone rubber parts, compression moulding, or PTFE/PFA coatings, our team can review your drawings and requirements and advise on materials, tooling, and production methods.
