Vacuum Glass Suction Cups
JS8641 Aluminum alloy suction cup single glass vacuum suction cup
The aluminium single cup: 425 g, rated 50 KG horizontal and 30 KG vertical suction.
Product Overview
The aluminium single cup: 425 g, rated 50 KG horizontal and 30 KG vertical suction. Moving from plastic to aluminium alloy adds 105 g and 10 KG of horizontal capacity, and gives a body that survives being dropped on a workshop floor.
Key benefits
Why Buyers Choose This Model
Aluminium Alloy Body
A metal body rather than plastic, which survives the handling a lifter gets in a glass shop and holds its shape so the pad stays flat.
50 KG Horizontal Suction
25 percent more than the plastic model at the same 30 KG vertical rating. For panels lifted flat, that is the useful figure.
Three Stock Finishes
Yellow, silvery and golden as stock, plus custom colours. The finish is also the anti-oxidation protection on an aluminium body.
30 Per Carton
One per inner box and 30 per master carton at 65 x 39 x 25 cm, the same high-density carton as the plastic model.
Application scenarios
Where It Is Used
- Single panes and tiles up to the rated load
- Glass shop handling between racks and benches
- Tool distributor ranges needing an aluminium single cup
- Workshops where plastic bodies have broken
Who it is for
The Buyers This Model Suits
Glass Processing Shops
Handles panels repeatedly and wears out plastic bodies faster than pads.
Tile Installers
Moves individual large tiles where a single cup is enough and a dual claw is in the way.
Distributors Building A Ladder
The aluminium single cup is the second rung, above plastic and below dual claw.
Problems it solves
What It Fixes
Plastic Bodies Cracking
An aluminium alloy body does not, and a cracked body means a pad that no longer sits flat.
Reading The Wrong Rating
50 KG horizontal and 30 KG vertical are different numbers for physical reasons. Use the one that matches the orientation.
Corrosion In A Wet Shop
The coloured finish is also the anti-oxidation treatment on the aluminium.

Materials and manufacturing
How This Model Is Made
Parts for the JS8641 are produced in our own workshops in Jinli Town, Zhaoqing. This model uses both routes: its moulded components come off our five horizontal and three vertical injection moulding machines, and its metal parts come off our fifteen automatic punching machines, nine automatic lathes and three welding machines. Tooling is designed and cut in our own mould room, which is why a change to this model does not queue behind another factory's schedule.
Quality Control
- Every model is weighed against its declared net weight during production, so the carton weight on your packing list matches what arrives.
- Stamped parts are produced in house on 15 automatic punching machines and 9 automatic lathes, so dimensional consistency is controlled at source rather than inspected on arrival.
- Moulded parts come off 5 horizontal and 3 vertical injection moulding machines running up to 10,000 mould open-and-close cycles per day, with tooling maintained in our own mould room.
- The quality management system was certified to ISO 9001:2015 in August 2023, with a certificate valid to 31 July 2026.
- Cartons are counted against the packing list as they are loaded into the container at our own factory door.
Certifications
The quality management system was certified to ISO 9001:2015 in August 2023, under standard GB/T19001-2016, for the manufacture and sale of glass caulking guns and sealant guns. The certificate on file runs to 31 July 2026; ask us for the current renewal status before relying on it. A TUV Rheinland assessment was obtained in 2016.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.
- Aluminium Tube Painting: Up to 10 colours with customisable patterns.
- Aluminium Tube Laser Engraving: Engraved logos, text and patterns on stamped fittings and aluminium tubes.
- Self-Adhesive Logo Labels: Applied to the product in the position the buyer specifies.
