Use extruder moulds instead of expensive injection moulding machines. That’s the suggestion for plastics manufacturers who only produce limited quantities of transition flanges – and there’s plenty of money to be saved.
Instead of paying millions for injection moulding machines and costly injection moulding tools, manufacturers only need to invest a tenth of that money. RIVAL’s moulds are used on an existing extrusion line, and it is easy to replace the pipe tool with the moulds when switching between the production of pipes and flanges.
Manufacturing larger pieces
This solution is ideally suited for the production of flanges, transition units, couplers and larger moulded pieces. “Usually, flanges and other fittings are produced by injection moulding,” says Freddy Andersen, Development Manager at RIVAL. ”When dealing with larger components, for example, clients can employ RIVAL’s moulds alongside an existing extruder already used in pipe production.
The moulds are particularly well suited for the production of transition flanges with a diameter of more than 200 mm. RIVAL has supplied moulds for the production of flanges with a diameter of up to 1,000 mm.
”This tool opens up a whole new world of possibilities for plastics manufacturers,” says Henrik Holvad, Managing Director of RIVAL. ”They can avoid purchasing from subcontractors and instead manufacture the flanges, larger pieces and other components they need for their customers inhouse. At the same time, the tool allows them to expand their production to include completely new products.”
And there are savings to be made. Plastics manufacturers can make better use of their existing production lines since they can switch between the production of pipes and flanges rapidly and easily, using equipment that costs only a tenth of what an injection moulding machine would set them back.”
From idea to production
”The moulds are an excellent example of how we turn our clients' problems and ideas into production-ready solutions,” says Henrik Holvad. ”In this particular case, Wavin had an actual problem and we came up with this innovative solution through joint brainstorming and development work.”
28 moulds to Cuba
”The moulds have been sold both at home and abroad,” says Jesper Andersen, Export Manager at RIVAL. ”Recently, we sold 28 different moulds for the production of transition flanges to one of Raúl Castro's state-owned companies in Cuba. The company produces plastic pipes. Every mould has been carefully made to meet the client’s needs, and RIVAL has worked closely with the Cuban company to get the 28 drawings required in place before RIVAL could start producing the moulds. The moulds have now been delivered and are ready to enter into the production process.”
