FAQs
Q: What materials can be laminated with PE foam for roll forming?
A: PE foam provides good binding compatibility with sheets of PP, PVC, ABS, acrylic plastics along with aluminium, steel and even paper or textile. Adhesive type and process parameters need tuning for each combo.
Q: What CNC capabilities are needed for laminated profile roll forming?
A: Standard CNC 3-axis controls for incremental profile bending movements suffice for most designs. Complex shapes may utilize specialized 5-axis controls for optimal material flow and forming.
Q: How to calculate machine rating needed for my production scale?
A: Material width in mm multiplied by maximum line speed in m/min provides the hourly linear meter output. Comparing this against current and projected production volume requirements gives machine rating needs.
Q: Can polymer foam sheets be directly roll formed without lamination?
A: Yes, but doing so restricts profile geometry to mostly simpler shapes like tubes due to flexibility and springback tendencies needing more tooling stations. Lamination provides structural reinforcement allowing complex profile roll forming.
Q: How does roll formed laminated foam compare with extruded foam on insulation properties?
A: Directly extruded foam sheets generally offer slightly better insulation per unit thickness owing to inherent material expansion during exit. But thinner laminated foam can match insulation levels at lower overall weight.
Q: What regular maintenance helps sustain roll formed laminate quality?
A: Activities like machine cleaning, belt tensioning, lubrication, visual inspection, sensor checks, calibration, heating system health etc. are vital for uninterrupted production without quality fluctuations.
Q: Can decorative laminates be added to foam profiles via roll forming?
A: Yes, visual allure can be enhanced by using colored laminates or by post-production methods like painting, printing, hot stamping. Even embedding wires, beads is possible for lighting or heating effects.
Q: How to minimize scrap generation during foam laminate roll forming?
A: Scrap is unavoidable when stabilizing production but can be reduced via positive feed control, edge guiders, optical defect monitoring and precision cutting to length after line stabilization.
