Discover the advantages of plastic injection moulding for your business
Optimise your design with injection moulding—a highly adaptable, cost-efficient solution for delivering precision-engineered parts at scale. Whether you are developing a new product or refining existing ones, our comprehensive suite of injection molding capabilities provides significant technical advantages for your products.
Cost-effective at
scale
As production volumes increase, the cost per unit dramatically decreases. Once your mould is created, each part can be produced rapidly and consistently, making injection moulding particularly economical for medium to high-volume production runs.
Design freedom & complexity
Create complex geometries and intricate features that would be impossible or prohibitively expensive with other manufacturing methods. From snap-fits to living hinges, injection moulding enables sophisticated design features while maintaining structural integrity.
Consistent quality & precision
Every part is produced with exceptional accuracy and repeatability. Our advanced injection moulding systems maintain tight tolerances and consistent material properties across production runs, ensuring your products meet the highest quality standards.
Versatile material selection
Choose from engineering-grade plastics with specialised properties like flame retardance, impact resistance, and UV stability. We also offer biodegradable options, high optical clarity, and custom finishes - ensuring the perfect material for your application.

Designing for a sustainable future
Material selection
Choose from our range of eco-friendly materials, including recycled polymers, biodegradable options, and materials designed for recyclability. We'll help you select materials that balance environmental impact with performance requirements.
Design for longevity
Create products that stand the test of time through robust design principles, appropriate material selection, and quality manufacturing. We'll help you identify potential wear points and design solutions that extend product life.
Circular design principles
Create and design circular manufacturing systems that allow products to feed into new stock.
Waste reduction
Optimise your design to be easily recyclable to New Zealand and international standards. Design focus on end of life as well as functionality.
Industry-leading recognition backing our promise to quality and sustainability
Computer model design
We'll bring your product to life in the digital world first, creating detailed 3D models that let you see exactly how your product will look and function. Our design team works closely with you to perfect every detail, making sure your product isn't just beautifully designed, but also ready for efficient manufacturing. Before any tooling begins, we'll test how all the pieces fit together and identify any potential manufacturing challenges – saving you time and money.
Technical Documentation
Getting the documentation right is crucial for successful manufacturing. We'll create a complete set of technical drawings and specifications that cover everything needed to make your product perfectly, every time. From precise measurements to assembly guides, material choices to quality standards – we document every detail so there's no room for error. Think of it as your product's blueprint for success.
3D printed or CNC prototypes: Experience your product before production
See and feel your product before moving to full production. Our rapid prototyping service lets you validate your design, test fits and functions, and make refinements early in the development process. We can produce precise 3D printed parts for smaller components and create large-scale CNC'd prototypes for more substantial items or complete assemblies. It's a quick and cost-effective way to ensure your product is exactly right.
