Pattern & Mould Making
Pattern & Mould Making – Precision Tools for High-Quality FRP Production
Craft Fibreglass specialises in pattern and mould making for composite and fibreglass manufacturing. Our team creates high-quality patterns, master tools and production moulds that allow you to manufacture strong, accurate and consistent components across all production runs.
With decades of experience in mould making, we support a wide range of industries including transport, telecom, marine, architecture, infrastructure, industrial systems and custom fabrication. Whether you need a mould for a single prototype, a small batch of parts or long-term high-volume production, we design tooling that delivers reliability, performance and efficiency.
Mould making is the foundation of any composite product. A well-designed mould reduces defects, saves labour time, improves surface finish and ensures every manufactured unit matches the original design. Our goal is to help you produce parts that fit correctly, look clean and function as intended — every single time.
We work with your 3D CAD files, technical drawings, sketches or existing parts to create accurate, durable tooling suited to your manufacturing needs. Throughout the process, we collaborate closely to ensure the mould supports your product goals, installation conditions and production requirements.
Complete Pattern & Mould Making Services
We provide a complete mould making service that covers concept review, CAD modelling, pattern fabrication and final mould construction. This ensures every step is controlled and consistent, resulting in tooling that performs reliably in real manufacturing environments.
Our services include:
- Pattern making
- Master tool fabrication
- Plug construction
- Single-use prototype moulds
- High-durability production moulds
- CNC-machined tooling
- Fibreglass and composite mould fabrication
- Tool repair, modification and refinishing
This end-to-end capability allows us to support projects at any scale, from small custom items to large structural components.
Understanding Your Project Requirements
Every mould begins with a clear understanding of what the product needs to achieve. Before the tooling process starts, we review the design, usage environment and product goals to ensure the mould supports efficient manufacturing.
We assess:
- Part size and complexity
- Required surface finish
- Strength and structural demands
- Expected production volume
- Resin and reinforcement types
- Draft angles and release needs
- Fitment, alignment and mounting requirements
This early analysis helps determine the correct tooling materials, construction method and reinforcement layout.
Pattern Making – The Foundation of Quality Moulds
A high-quality mould begins with an accurate pattern. The pattern defines the shape, surface and geometry of the final component. Our team fabricates patterns using methods that suit your design, budget and production goals.
We use materials such as:
- High-density foam
- MDF or timber
- CNC-machined board
- Composite prototype shells
- Existing parts adapted into patterns
Patterns are shaped, detailed and coated to achieve a smooth surface, allowing for clean mould construction and consistent part quality.
We pay close attention to symmetry, dimensions and any design details that influence fit and alignment. This ensures the pattern reflects your final product with complete accuracy.
Master Tools & High-Precision Moulds
Once the pattern is complete, we build the master tool or production mould. This stage focuses on durability, accuracy and surface quality.
We create moulds that support:
- Hand lay-up
- Vacuum infusion
- Resin transfer
- Gelcoat finishing
- Composite reinforcement
Each mould is built with structural strength in mind, ensuring stability, rigidity and long-term performance. We reinforce moulds to prevent warping, flexing or distortion during use.
Types of Moulds We Manufacture
We produce moulds for many applications and production environments. Based on your requirements, we help you choose the most suitable mould type.
Mould types include:
- Prototype moulds – for one-off parts or design validation
- Medium-volume moulds – reinforced fibreglass tools for regular production
- High-volume moulds – heavy-duty tools built for long service life
- Single-part open moulds – simple shapes and small components
- Complex multi-part moulds – for shapes requiring multiple release sections
- CNC-machined moulds – high-accuracy tooling for tight tolerances
- Matched tools – upper and lower moulding surfaces for precision parts
This flexibility allows us to support industries with diverse shape, strength and production requirements.
CAD Modelling & Digital Preparation
For many projects, we create or refine 3D CAD models to guide the mould making process. CAD ensures the part meets dimensional accuracy, draft angles and release directions.
Digital modelling helps verify:
- Part geometry and thickness
- Reinforcement placement
- Tool split lines
- Trimming edges and cut-outs
- Mounting and connection points
A strong digital foundation reduces risk and speeds up mould development.
Production Efficiency & Cost Reduction
Well-designed tooling does more than produce accurate parts — it improves your manufacturing workflow. Our moulds are built to reduce production time, minimise rework and deliver consistent quality.
Benefits include:
- Faster lay-up and curing
- Cleaner release
- Improved surface finish
- Less trimming and correction
- Fewer defects or repairs
- Reduced labour requirements
This results in lower long-term manufacturing costs and more predictable output.
Mould Repair, Upgrades & Modifications
In addition to new mould making, we also provide mould restoration and improvement services. If your current tooling is worn, damaged or outdated, we can restore it to working condition or upgrade its design.
We assist with:
- Surface refinishing
- Structural reinforcement
- Seal replacement
- Draft improvements
- Patch and repair work
- Release system upgrades
These services help extend the lifespan of existing tooling and improve part quality.
