Trexel and Roctool announce global
lightweighting alliance
Roctool (Euronext Growth - FR0010523167 - ALROC), specialist in heating and cooling technologies for plastics and
composites, announced at Chinaplas 2026 in Shanghai (Hongqiao), China, a collaboration between two industry leaders set
to expand the boundaries of lightweight injection molding.
A complementary technology approach to lightweighting
At Chinaplas 2026 in Shanghai (Hongqiao), China, two industry leaders in injection molding have unveiled a
collaboration set to expand the boundaries of lightweight injection molding. Roctool's Heat & Cool molding process,
known for premium surface finishes and high-quality plastic parts, will be combined with Trexel's globally recognized
MuCell microcellular foaming technology, opening new possibilities in both part quality and weight reduction. The
joint solution complements each company's established standalone offering, providing an additional path for customers
who prioritize lightweighting alongside exceptional surface quality.
Delivering performance, aesthetics and weight reduction
This strategic global alliance brings together complementary expertise to deliver a powerful, integrated approach to
lightweighting and advanced surface finishing. Building on the partners' proven technologies, manufacturers can adopt
the combined approach to reach new standards in weight reduction, aesthetics, and molded-part performance.

Supporting global adoption and customer applications
This collaboration goes beyond technology: it reflects a shared commitment to delivering measurable value for customers
worldwide. To support adoption, Trexel and Roctool are establishing multiple demonstration and trial platforms across
Europe and Asia, enabling live showcases of the joint solution and hands-on support tailored to a wide range of
part-design requirements.
Next steps and roadmap
"This global alliance marks a major step forward in lightweight injection molding. By bringing our technologies
together, we're enabling manufacturers to reduce part weight and material usage without compromising performance,
quality, or process robustness," said Patrick Tong, Managing Director of Trexel Asia.
Together, the partners aim to set a new benchmark for lightweighting: premium surfaces, strong part performance, and
tangible material savings.
"With Roctool Heat & Cool and Trexel MuCell working together, customers can achieve premium surfaces, high-fidelity
replication, increased flow length, and meaningful weight reduction in a single, production-ready approach," said
Mathieu Boulanger, CEO, Roctool.
With this alliance, Trexel and Roctool open a new chapter for the plastics industry, accelerating innovation and
enabling lighter components with premium aesthetics, robust performance, and improved material efficiency.
