CONVUM PCD Series Ring Pads | Vacuum Gripping for CDs & Hollow Parts

• Ring-Groove Suction Face: Circular groove avoids center loading and targets ring/hollow parts for stable, shift-free positioning.
• For Circular/Hollow Workpieces: Ideal for CDs/DVDs, ring components, and holed sheets—improves contact consistency and reduces deformation risk.
• Inner-Diameter Options: ø19 / 20 / 23 / 29.5 / 34 / 38 / 46 mm to match opening size and required holding force.
• Stable Holding & Accuracy: The annular seal distributes load evenly, reducing slip/leakage and boosting repeatability for high-speed pick-and-place.
• Material Choices: N (NBR) for general, oil-resistant duty; S (Silicone) is softer and minimizes marking for mark-sensitive or cleaner processes.
• Applications: Handling of optical/media discs (CD/DVD), ring gaskets/gear rings, holed thin plates, hollow parts in electronics/semiconductor lines, high-speed automated pick-and-place.

Q1: What are the main applications of the PCD series?
A: Precision pickup/transfer of CDs/DVDs, ring components, holed sheets, and other hollow workpieces.

Q2: How is it different from flat pads?
A: The ring-groove design avoids center pressure and delivers more reliable sealing/positioning on ring and hollow parts, reducing deformation and slip.

Q3: What size options are available?
A: Inner diameters ø19, 20, 23, 29.5, 34, 38, 46 mm—select by opening size and load conditions.

Q4: Is it suitable for high-speed automation?
A: Yes. The annular seal improves repeatability for fast pick-and-place; verify vacuum build/holding against your cycle time on tool.

Q5: How should I choose between N and S materials?
A: N (NBR) is general/oil-resistant; S (Silicone) is softer and minimizes marking for mark-sensitive parts or cleaner environments.

Q6: Does it help with thin-wall or deformation-prone parts?
A: Yes—by avoiding center loading and spreading force around the ring, it reduces local deformation and scratching; upsizing ID can further optimize loading.

Q7: Any mounting compatibility notes?
A: Confirm pad-holder thread/interface and clearance. If using locating pins/fixtures, ensure they don't interfere with the annular sealing area.

Q8: What are the cleaning and maintenance tips?
A: Use lint-free wipes and mild cleaners; inspect lip wear/hardening/cracks and replace pads when sealing performance declines.
