Needle gripper for wood-fibre & lightweight materials
The NGR NeedleGripper combines needle grippers and suction cups for handling wood-fibre, lightweight and insulation materials. Ideal for air-permeable materials that cannot be held reliably by traditional suction cups.
The Barbaric NGR needle gripper is a special lifter for porous, soft or non-vacuum-compatible materials. Instead of suction, it works with fine needles that enter the workpiece a few millimetres deep and secure it in a positive-fit hold. Typical materials are insulation boards made from mineral wool, wood fibre or polystyrene, MDF blanks, OSB, open-cell foams and felt or non-woven materials. The needle penetration depth is dimensioned so that the workpiece is not visibly damaged — after release, the insertion points are practically invisible. The NGR is a niche solution but often the only economical automation option for manufacturers of insulation boards, packaging material or acoustic elements. Asamer engineers needle gripper systems in Czech Republic, Slovakia and Hungary — including material testing, needle design and integration into existing production lines.
Mineral wool and wood fibre insulation boards cannot be handled by vacuum — their open-cell structure lets air pass through. The NGR handles automated handling at the line end, during stacking or when loading the packaging line, replacing physically heavy manual work.
Raw-state panels (before coating or sanding) offer no smooth suction surface. Open-pore cardboard or textured corrugated board also escape classic vacuum handling. Here the needle gripper secures handling — important for example when loading a laminating station or stacking from a press.
The NGR is the right choice when regular vacuum lifters fail on your material. Before purchase, Asamer conducts a material test — sample workpieces are tested with the needle gripper to verify penetration depth, holding force and surface appearance. For standard panel material, the UWL-3 is the more economical alternative.
For typical insulation materials, needle marks are practically invisible after release because the fibres spring back. On smoother materials such as MDF, the needles leave fine points that are no longer visible after later sanding or on a coated surface.
Service life depends on the material — several hundred thousand strokes are common on mineral wool. Asamer offers maintenance packages with regular needle replacement, inspection of penetration depth and control of the retraction mechanism.
Brittle material such as glass or hard foams is not suitable for needle grippers — there is a risk of cracking. For fragile flat material, special vacuum solutions with finer suction cups and reduced acceleration are the better choice.
