ROCTOOL: Live at K-Show: Roctool Slashes Cycle Times in High-Heat Molding Demonstrations

Live at K-Show: Roctool Slashes Cycle Times in High-Heat Molding Demonstrations

 

• Live molding of PEI & PEEK at over 200°C with radically shorter cycles and exceptional part quality at Roctool booth Hall 15, C41
• Displaying 10 mm optical lenses, with 50% shorter cycle time compared to conventional processes
• New Ultra-Compact Air-Cooled induction generators running live at the booth

 

At K-Show 2025, Roctool will unveil live demonstrations never seen before at this event: high-temperature molding with unmatched speed, quality, and efficiency. The demonstrations will take place on the Roctool stand with a KraussMaffei injection molding machine, Roctool’s long-standing partner at trade shows.
The KM CX 80 is equipped with the new LRXplus linear robot.
 

For over 20 years, Roctool has been perfecting its proprietary Heat & Cool induction technology, heating mold surfaces to the right temperature in seconds, then actively cooling them. The result: shorter cycles, flawless surfaces, and lower energy consumption. Unlike traditional oil or hot water systems, Roctool’s “dry” induction heating is clean, safe, and highly reliable.

 

• Engineering Resins molded at 200°C+

 

Roctool will run during the show, a 2-cavity tool producing precision housing in PEI+GF and PEEK:

• Mold temperature up to 300°C, for example heating from 130°C to 230°C in just 9 seconds
• 40% cycle time reduction compared to standard processes
• 30% energy savings per shot versus traditional molding
• Superior surface quality: no weld lines, no exposed fibers, no surface defects
• Roctool technology can also push molds up to 300°C when required, opening the door for thin-wall and advanced designs that conventional thermoregulation cannot match.

 

• Game-Changer for Lenses & Optical Components

 

Roctool will showcase 10 mm thick PMMA and PC lenses:

• Up to 50% cycle time reduction thanks to rapid high-temperature induction heating, followed by low-temperature cooling.
• Ability to mold very thick lenses in a single shot, with a short cycle time.

 

 

 

 

A breakthrough in optics and lighting for thick-walled applications, including light guides and headlight components. This technology overcomes the cooling limitations that have long challenged optical injection molding.

 

• Why Roctool is Different

 

Traditional systems (oil, hot water, resistive heating) can’t reach such high temperatures quickly and suffer from long cooling times. Roctool climbs above 300°C in record time, then cools rapidly with colder water.
Every cycle benefits from precise thermal control, offering:

• Shorter production cycles and lower costs than conventional molding
• Greater process efficiency compared to traditional methods
• Higher and more consistent part quality than standard molding

 

• Management Statement

 

“At this year’s K-Show, we are proving live that Roctool’s advanced induction technology achieves cycle times never seen before for high-heat resins, offering production stability and superior part quality, while delivering significant energy savings.” Mathieu Boulanger, CEO of Roctool.

 

• Partnerships at K-Show

 

These demonstrations are powered by Roctool’s latest Heat & Cool systems, with the mold manufactured by Moldetipo (Portugal). Live runs will take place daily on a KraussMaffei CX 80 with the new LRXplus linear robot with high-performance materials from SABIC (ULTEM™ PEI+GF) and SYENSQO (KetaSpire® PEEK).
