JS8640 Thick Plastic Glass Suction Cup Vacuum Suction Cup
The entry lifter: a thick plastic single cup at 320 g, rated 40 KG horizontal and 30 KG vertical suction.

Product Overview
The entry lifter: a thick plastic single cup at 320 g, rated 40 KG horizontal and 30 KG vertical suction. It is the lightest and cheapest cup in the range, built around a premium rubber pad and a press-and-release anti-slip handle rather than around a metal body.
Why Buyers Choose This Model
320 g, The Lightest Cup Here
Thick plastic rather than die-cast aluminium, which halves the weight against the single aluminium cups and keeps the price at the bottom of the range.
Press-And-Release Anti-Slip Handle
The handle incorporates a press-and-release anti-slip feature for effortless lifting, which is the whole interaction on a single-cup lifter.
Premium Rubber Pad
The pad maintains its shine and adhesion over extended periods, preventing detachment. On a lifter the pad is the product, whatever the body is made of.
30 Per Carton
One per inner box and 30 per master carton at 65 x 39 x 25 cm, the highest density in the suction cup range.
Where It Is Used
- Small glass panes and tiles
- Occasional handling in a workshop
- Retail and DIY tool ranges
- Light-duty positioning where 30 KG vertical is sufficient
The Buyers This Model Suits
Retail And DIY Channels
Needs a lifter at a price a homeowner or light trade buyer will pay.
Workshops Handling Small Panels
Moves tiles and small panes where a 250 KG three-claw is absurd.
Distributors Anchoring A Range
Every suction cup range needs a bottom, and this is it.
What It Fixes
Over-Specifying For Small Panels
A 1 kg three-claw lifter on a bathroom tile is cost and weight without benefit.
Pads That Harden And Let Go
The premium rubber pad is specified to keep its adhesion over extended periods, which is the failure this range is judged on.
Freight On Low-Value Items
30 per carton keeps the freight component of a cheap product small.
How It Is Built
Powerful Suction Force
The suction cup boasts a strong adhesion capability, firmly attaching to various materials for secure and stable usage.
Versatile Anti-Slip Handle Design
The suction cup handle incorporates a press-and-release anti-slip feature, facilitating effortless lifting and ensuring long-term durability and peace of mind.
Premium Rubber Pad
The high-quality rubber pad maintains its shine and adhesion over extended periods, preventing detachment and ensuring sustained effectiveness.

How This Model Is Made
Parts for the JS8640 are produced in our own workshops in Jinli Town, Zhaoqing. This model is predominantly a moulded product, made on our five horizontal and three vertical injection moulding machines, which run up to 10,000 mould open-and-close cycles per day. 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.

Getting The Best Out Of It
Step 1
Clean and dry the panel surface; dust, water or frost all reduce the rating.
Step 2
Press the cup flat to the surface and operate the handle to draw the vacuum.
Step 3
Use the 30 KG vertical figure for a panel carried upright and the 40 KG horizontal figure for a panel lifted flat, with margin.
Step 4
Release the vacuum before storing, and check the pad for hardening or embedded grit before every job.
