Silicone Rubber Sucker Suction Pneumatic Vacuum Cups
Custom Silicone Vacuum Cups Manufacturer
Custom silicone vacuum cups (also called silicone suction cups or pneumatic vacuum cups) play a core role in automated material handling systems. They are widely used in robotic pick & place, packaging machines, CNC automation, glass handling, electronics, and industrial transfer systems.
Suconvey specializes in designing and manufacturing custom silicone vacuum cups optimized for:
superior sealing performance
reliable grip force
long service life
repeated automation cycles
Our silicone vacuum cups are engineered to work in pneumatic vacuum systems, ensuring stable handling even on delicate, curved, or uneven surfaces.
Silicone Rubber Sucker Suction
Silicone vacuum cups are flexible gripping elements integrated into vacuum suction systems. When connected to a vacuum pump, they create a pressure differential that allows secure lifting of items without mechanical clamping.
Compared to traditional rubber cups, silicone vacuum cups offer:
- better chemical and heat resistance
- improved elasticity and conformability
- gentler surface contact (ideal for delicate parts)
- higher durability in repeated cycles
Suction cups come in multiple shapes and sizes such as:
- flat face
- bellows
- stepped
- conical
- multi-bellows
- custom profiles according to your application

Packaging & Shipping Information
To protect the product during global transportation and storage, we apply export-grade packaging and provide flexible shipping solutions.
Pre-Shipment Inspection
Each batch is inspected before packaging to confirm hardness, thickness, surface condition, and visual uniformity. Batch codes are recorded and compliance documentation may be provided when required for regulatory purposes.
Packaging Method
Silicone products are wrapped with protective film to prevent dust, moisture, and surface damage. Several rolls are placed into reinforced cartons, which are then secured on fumigation-free pallets using straps and stretch film.
Shipment Options
We regularly ship to customers in Europe, North America, and Asia through sea freight, air freight, or express courier for urgent testing needs. Both FCL and LCL shipments are available.
Documentation Support
All necessary export documents can be provided for customs clearance, including commercial invoice, packing list, bill of lading or airway bill, certificate of origin, and food-contact compliance statements or test reports when applicable.
Sample Delivery
Material samples and short test products can be supplied for validation and equipment trials. Samples can be sent via DHL, FedEx, UPS, TNT, or using your appointed courier account.
After-Arrival Support
If any damage or discrepancies are discovered during unloading or inspection, customers may contact us within 7 days with photos and batch information. Our team will respond promptly to assess the situation and provide a reasonable solution.
