The Rag Cutter
Bringing Innovation to Reality: Uniplas and RagCutter’s Collaborative Journey
In the world of product development, a great idea is only as strong as the materials and craftsmanship behind it. At Uniplas, we take pride in transforming visionary concepts into tangible, high-quality products. One such journey was our collaboration with RagCutter, a team driven by ingenuity and practicality, seeking to develop a unique solution that required expert guidance in design evolution, material selection, tooling consultation, and manufacturing strategy.

From Concept to Reality
At Uniplas, our role extended beyond simple material selection—we worked closely with RagCutter to organically evolve their design, ensuring it was optimised for injection moulding. While the initial concept was strong, translating it into a manufacturable product required refining key elements to suit efficient production methods without compromising functionality.
The Challenge of Imitation
As with any well-designed and innovative product, the success of the RagCutter development soon faced an unfortunate but familiar challenge: cheap overseas knock-offs. Once the product was launched, imitation versions appeared for sale on platforms like Temu—visually similar but fundamentally flawed.
Because Rag Cutter and Uniplas committed to local production, counterfeit manufacturers were only able to copy the superficial appearance, but they couldn’t replicate the core design, material integrity, or functionality. This meant that while the knock-off may have looked similar, its performance was inferior, highlighting the importance of proper design and testing.
Had Rag Cutter opted for overseas production, there would have been a greater risk that the imitation product could have been produced in the same tooling, potentially diluting the value of the original design and jeopardizing quality control. By choosing New Zealand-based manufacturing, RagCutter ensured that their product remained distinct, durable, and true to its original purpose.
Watch: Authentic vs. Counterfeit Comparison
The Value of Authentic Innovation
This journey underscores a critical takeaway: quality plastics manufacturing and strong partnerships protect innovation. Here at Uniplas, we don’t just produce products—we safeguard ideas, ensuring they are developed to high standards while mitigating risks associated with intellectually theft .
Our collaboration with RagCutter is a testament to the power of choosing the right materials, the right tools, and the right production strategy. True innovation goes beyond price—it’s about function, quality, and form. Whilst imitation may exist, nothing can replace the integrity of a product built with expertise and precision, and also built in your own back yard.
