CONVUM PL Series | Multiple-Bellows Pads for Soft & Uneven Surfaces

• Multiple-Bellows Design: Longer compliance (stroke) and cushioning to absorb height errors and micro-motions on uneven surfaces.
• Conforms to Soft/Curved Parts: Better sealing on textured, curved, or deformable workpieces—reducing leaks and drops.
• Size Range: ø20 / 30 / 40 / 50 mm for easy sizing by contact area and cycle time needs.
• Materials / Specs:
  • S4 (Silicone): 40Hs hardness, light blue, −60 to 250 °C.
  • S5 (Silicone): 55Hs hardness, milky white, −60 to 250 °C.
• Wide Temperature Stability: Silicone maintains elasticity and sealing across wide temperature swings.
• Applications: Electronics/appliance assembly, thin-sheet pick, curved cosmetic parts, mixed-model lines with irregular shapes.

Q1: What workpieces are PL pads best for?
A: Uneven, curved, or easily deformable parts—electronics modules, appliance exteriors, thin sheets.

Q2: How does PL differ from standard dual-bellows pads?
A: PL uses multiple bellows, delivering longer stroke and better cushioning for height variation and curved surfaces.

Q3: What sizes are available?
A: ø20, 30, 40, 50 mm.

Q4: How do I choose between S4 and S5?
A: Both are silicone rated −60 to 250 °C. S4 (40Hs, light blue) is softer for higher conformity; S5 (55Hs, milky white) is firmer for better support.

Q5: Is it suitable for high-speed handling?
A: Yes. The multi-bellows design keeps sealing reliable even at short cycle times; validate on-tool vacuum build/holding and tune orifice and motion profiles.
