On January 6th, Nordson XALOY released the company's patented single-screw, single-cylinder equipment package, which provides cost savings and versatility for two-component molding, while requiring much less investment than using separate injection molding. Complex co-injection molding system for the unit.
Nordson XALOY's system, called Twinshot, replaces standard screws and barrels with self-developed components, so that dual-components can be produced in a single-shot process with single-screw, single-shot and single-reduction Parts. The system can be used as an option on a new injection molding machine or as a retrofit kit for an old machine, in one or two days.
“Resin typically accounts for more than half of the cost of parts production. Two-component molding can use two different resins, so that the best balance between material function and cost can be achieved,†said Anton Hagen, global product manager for screw and multi-material forming. Said. “Nordson XALOY's Twinshot system has low investment costs and is easy to retrofit, so more plastics processors can enjoy the economic benefits of co-injection molding. In addition, the system operates better than co-injection with two injection units. The machine is simpler, takes up less space and consumes less energy."
The advantages of Twinshot two-component molding include: the use of high-cost specialty materials on the surface, the use of common materials in the core; the use of recycled materials or various sizes of materials in the core; the combination of structured cores and decorative surfaces; Various ways to add value to new products, such as combining a “feel-sensitive†TPE skin with a rigid core; both the advantages of a foam core (lightening weight and molding pressure without warping and dents), and A highly polished surface. Mr. Hagen cited the case of automotive mirror housings as a simple example of savings with the Twinshot system, which requires $5 material cost and $1 energy cost per housing. “By co-injection molding, it is easy to save 15% on material costs, reducing the resin cost per component by $0.75 and reducing the total cost per component by 12.5%.â€
