Van der Waals suction cup – VFC

Short Description:

VFC van der Waals force suction cups are inspired by the observation and imitation of the microscopic characteristics of geckofeet. Through special polymer materials and μm-level surface micro-molding processes, the suction cups can generate strong intermolecular forces with the surface of various objects to absorb The strength can reach 0.5kg/cm².Due to its special adsorption mechanism, no power supply, air supply or programming is required, it is simple and reliable, and can adsorb porous workpieces even in normal use in a vacuum environment, which greatly expands the application scope of automation equipment.

Application

VFC products are widely used in semiconductor, optical and other high‑precision fields. They are ideal for high‑accuracy, non‑damaging and stable suction and handling applications. Meanwhile, they overcome the strict pressure differential requirement of traditional suction cups and achieve reliable adhesion even in vacuum environments.

Features

Flexible & Adaptive, Non-Destructive Handling
- Bionic/polymer materials gently adapt to smooth surfaces
- Zero‑damage handling for wafers, lenses and precision parts

For High‑Gloss Porous Metal Parts & PCBs

No sealing or pressure difference required
Ideal for vacuum processes, porous metal parts and bare PCBs

Zero External Power, Plug‑and‑Play

Powered solely by van der Waals force, no air/power supply needed
Compact, quick‑install design for space‑limited workstations

Traceless Adhesion, Clean & Contamination‑Free

Particle‑free, residue‑free contact adhesion
Cleanroom‑safe, boosts yield for precision electronics and optics

Notes	* Service life tested under ideal conditions: room temperature, clean environment, smooth workpiece, regular cleaning. * Adhesion strength is closely related to test conditions such as detachment method, preload per unit area, and detachment speed. Test conditions for normal adhesion strength: smooth glass surface; VFC-D detached at 500 mm/min, VFC-A detached at 720 mm/min. Adhesion performance may decrease on low-energy surfaces (e.g., anti-stick coated surfaces).
