Who would have thought that sandwich molding is now achievable for injection-molded plastic parts! The Chameleon Series Hybrid Dual Injection Molding Machine by Ningbo Konger Machinery, equipped with its proprietary true sandwich injection molding technology, enables the seamless production of green-white layered injection-molded products, pioneering a new cost-saving and efficiency-boosting approach for injection molding operations.

As clearly demonstrated in the video, the outer layer of this sandwich injection-molded product is made from virgin TPU material, while the inner core is filled with recycled TPU. The finished product features a tight, seamless wrap and is molded in one single step, eliminating the need for subsequent manual assembly. This remarkable result is entirely attributed to the precise material control technology of Konger’s hybrid dual injection molding machine, which firmly encases one material within another—no secondary processing required, thus greatly streamlining the production process.

Hailed as a cost-cutting powerhouse in the injection molding industry, Konger’s Chameleon Series Hybrid Dual Injection Molding Machine boasts standout core advantages. By using recycled TPU for the inner core, it directly reduces raw material procurement costs without compromising the product’s surface finish or structural integrity. Meanwhile, the one-step molding process eliminates redundant intermediate procedures, enhancing production efficiency and reducing labor input—achieving dual optimization of production costs.

Whether for packaging components, daily necessities, or industrial parts, Konger’s true sandwich injection molding technology delivers perfect adaptability. It achieves the production goal of "cost savings inside, quality assurance outside", precisely addressing the industry’s pain point of balancing cost and quality in injection molding production.

Looking to create injection-molded products that are both cost-effective and premium-quality? Konger’s proprietary true sandwich injection molding technology, featured in Ningbo Konger Machinery’s Chameleon Series Hybrid Dual Injection Molding Machine, provides tailor-made solutions to help enterprises boost their core competitiveness.
