A common rule of thumb in the plastics industry is: "The higher the quality of the mould, the higher the quality of the final product."
That’s why we created our Premium Moulds range. These moulds are machined from solid Aluminium to ensure the highest quality surface finish and are designed specifically for the capabilities of our machines. They are the best choice for creating high detail, useful products from recycled plastic.
Turn recycled PP, HDPE, or LDPE into functional whistles at desktop scale. Each shot produces a single whistle with a clean, consistent finish, ready to use straight out of the mould. The generous logo space along the body makes this a practical product for branded merchandise, event giveaways, and educational demonstrations.
1 whistle per shot, less than 2 minutes per cycle, ~30 whistles per hour.
Designed for small batch production, promotional runs, and workshop demonstrations. A simple, universally recognisable product that works well for introducing people to desktop injection moulding.
Outdoor and adventure brands producing branded safety whistles from recycled plastic for retail or as a gift with purchase
Event organisers and conference teams creating functional, branded giveaways from waste plastic that attendees will actually keep and use
Schools and makerspaces demonstrating plastic recycling with a product that has an immediate, testable function
Promotional merchandise companies producing custom branded whistles for sports events, festivals, and corporate gifting
Community recycling projects creating useful everyday items that show the practical value of recycled materials
