Laminators play a critical role in delivering complete heat process solutions. Glenro provides radiant heat (infrared heaters and systems) and convective heat (hot air ovens) primarily for drying and curing applications. Laminators represent the conductive heat component of Glenro’s Proven Solutions® approach, delivering the simultaneous application of heat and pressure to stabilize, consolidate, or bond multiple material layers. By integrating radiant, convective, and conductive heat transfer and often combining them into a single engineered system, Glenro develops highly customized solutions tailored to each customer’s manufacturing process.
A laminator applies controlled heat and pressure to bond layers of material into a single, stable structure. Glenro’s Flatbed-Belt Laminator enables rapid heat transfer through two opposed, pressure-loaded, driven belts. Inside the heated tunnel, nip rolls provide additional compression to bond, stabilize, or consolidate materials. An optional pressure-loaded cooling section allows materials to be safely handled or wound before downstream processing. For example, Glenro laminators are commonly used to bond multiple substrate layers using heat-activated adhesive webs, powders, or films placed between materials.
Hot Roll laminators apply heat and pressure simultaneously, with cooling provided in a separate section if required. Belt laminators allow for extended dwell time and more controlled bonding conditions.
Glenro laminators are used to bond a wide variety of materials including fabric, nonwovens, metal foils, foams, composite panels, filtration media, ballistic materials, and fuel cell films.
Key industries include:
Emerging growth areas include carbon fiber applications and laminated films for fuel cell manufacturing. As advanced materials evolve, manufacturers increasingly rely on precise lamination processes to ensure structural integrity and performance, making high-performance laminators more critical than ever.
Glenro laminators are engineered for durability, precision, and repeatable product quality. Heavy steel construction and laser-cut components ensure structural integrity and exact fit-up. From an operator and maintenance standpoint, the systems are user-friendly and built for long-term reliability.
Key benefits include:
Many optional features can be integrated to enhance throughput and process accuracy, including high-pressure nip systems, advanced material handling solutions, auto bed gapping, cross-machine zoning, and multiple control platform options such as Allen-Bradley or Siemens.
For non-rigid substrates, Glenro’s proprietary Silcurv® heating technology delivers superior bonding performance. Each Silcurv® element is individually controlled and designed with a slight radius, creating a sine wave contact pattern as substrates pass through the laminator. Elements are staggered face-up and face-down to provide uniform heat from both top and bottom surfaces. This configuration eliminates cold spots, minimizes temperature overshoot, and ensures even adhesive activation.
Precise control of time, temperature, pressure, and cooling allows adhesives to maintain optimal viscosity which prevents excessive flow-through while ensuring strong anchoring between layers. The result is efficient heat transfer, improved bond strength, and enhanced product consistency. For rigid materials, Glenro’s Conductaplane™ heater design provides flat opposing heat surfaces engineered specifically for structural applications.
One customer currently laminating ballistic materials experienced such improved performance and reliability with their Glenro laminator that, after two years of operation, they purchased a second unit to replace a competitor’s machine. This reflects a common outcome. When manufacturers experience the consistency, control, and support Glenro provides, they continue to invest in Glenro solutions.
At the Glenro Technical Center, customers can confirm feasibility, verify process parameters, and produce test samples using their own materials. Glenro also offers complete contract laminating services, allowing customers to evaluate finished parts before committing to equipment purchases. From early-stage R&D through full production implementation, Glenro works closely with manufacturers to develop the most effective heating and laminating solution possible.
