Mould making is a critical stage in composite manufacturing and casting, directly influencing part quality, surface finish and production efficiency. From prototype development to repeated production runs, selecting the correct mould materials, release systems and casting resins is essential. At Tricel Composites, we supply a comprehensive range of mould‑making materials designed to support professional composite manufacturers, fabricators and engineers across Ireland.
Moulds define the geometry, finish and dimensional accuracy of composite or cast parts. Whether producing GRP, carbon fibre components or cast polyurethane parts, the mould system must be stable, durable and compatible with the chosen resin and reinforcement.
Effective mould making delivers:
Tricel Composites supports mould making across multiple processes including hand lay‑up, resin infusion, vacuum casting and polyurethane casting.
RTV silicone rubber (room‑temperature vulcanising silicone) is widely used in mould making where flexibility, detail reproduction and easy demoulding are required. Silicone moulds are particularly effective for complex shapes, undercuts and detailed castings.
Key advantages of RTV silicone rubber include:
RTV silicone rubber is commonly used in prototype moulds, short‑run production and complex casting applications where rigid moulds would be impractical.
For more demanding applications, rigid tooling systems are used to produce moulds capable of repeated production cycles. A tooling agent is applied during mould construction to create a stable, dimensionally accurate surface that can withstand repeated thermal and mechanical stresses.
Tooling agents are typically used in:
When properly applied, tooling agents contribute to longer mould life, improved surface quality and consistent part release.
A high‑quality mould release agent is essential in any mould‑making or casting process. Release agents form a barrier between the mould surface and the resin system, allowing clean demoulding without surface damage or contamination.
Benefits of using the correct mould release agent include:
Different mould materials and resin systems require compatible release agents. Tricel Composites supplies mould release solutions suitable for silicone, composite and rigid tooling applications.
Polyurethane casting resin is widely used in conjunction with silicone moulds and rigid tooling for producing detailed, high‑quality cast parts. Polyurethane systems are valued for their fast cure times, excellent surface finish and ability to replicate functional and aesthetic components.
Typical applications include:
Polyurethane casting resins can be formulated to achieve a range of properties, from rigid and impact‑resistant to flexible or elastomeric, making them extremely versatile for moulded part production.
Successful mould making depends on selecting materials that work together as a system. RTV silicone rubber, tooling agents, mould release agents and casting resins must all be compatible to avoid surface defects, cure inhibition or premature mould failure.
Key factors to consider include:
Tricel Composites provides technical support to help customers select mould‑making materials that deliver reliable and repeatable results.
Mould‑making materials supplied by Tricel Composites are used across a broad range of sectors, including:
From one‑off prototype moulds to small and medium production runs, the right mould‑making system ensures accuracy, efficiency and product consistency.
Tricel Composites Ireland supplies professional‑grade mould‑making materials trusted by composite manufacturers and fabricators. Our range includes RTV silicone rubber, tooling agents, mould release agents and polyurethane casting resin, selected to meet real‑world manufacturing demands.
By combining high‑quality materials with technical expertise, Tricel Composites supports the full mould‑making process—from pattern preparation to finished cast or composite parts.

Flat roofs move—and rigid roofing systems fail. With up to 300% elongation, TriRoof HPX flexes with the building, protecting roofs from cracking, splitting, and long‑term structural movement.
Marine plywood is still a wood‑based material and is prone to moisture damage over time. This article explains why it fails in wet environments.
Unpredictable weather is one of the biggest causes of roofing delays. TriRoof HPX is engineered to keep projects moving, allowing safe application on damp substrates and delivering instant waterproofing—whatever the forecast.
Resin infusion is a controlled composite manufacturing process that delivers strong, lightweight laminates. This article explores resin infusion equipment, flow media, spiral wrap and how the vacuum infusion process improves consistency and performance.
