Key benefits
Why Buyers Choose This Model
Silver Finish As Standard
Supplied finished silver rather than painted to order, which is the practical difference for a distributor whose whole tool range is silver.
Aluminium Alloy Body
The same metal body as the standard JS8641, which holds its shape so the rubber pad seats flat against the glass.
50 KG Horizontal, 30 KG Vertical
Identical ratings to the standard model. The finish changes nothing mechanical, and we do not claim otherwise.
Three Finish Options
Yellow, silvery and golden are all available on this body, so a range can run several finishes from one tooling.
Application scenarios
Where It Is Used
- Silver-finish tool ranges
- Glass shop handling of single panels
- Retail display ranges built around a consistent look
- Light glazing and tiling work
Who it is for
The Buyers This Model Suits
Distributors With A Silver Range
Builds a coherent shelf where every tool shares a finish, and needs the lifter to match.
Glass Shops
Handles single panels daily and wants a metal body rather than plastic.
Retail Buyers
Chooses on appearance as much as on rating at this end of the range, which is a legitimate reason to stock both.
Problems it solves
What It Fixes
A Range That Does Not Match
A yellow lifter in a silver range looks like an afterthought, and a finish option costs nothing in tooling.
Plastic Bodies In Professional Use
Aluminium alloy holds its shape and keeps the pad flat.
Assuming Finish Changes Capacity
It does not. Both JS8641 versions are 50 KG horizontal and 30 KG vertical.

Materials and manufacturing
How This Model Is Made
Parts for the JS8641 are produced in our own workshops in Jinli Town, Zhaoqing. This model is predominantly a metal product, made on 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.

Getting The Best Out Of It
Step 1
Clean and dry the glass; the rating assumes a smooth, clean, non-porous surface.
Step 2
Press the cup flat and draw the vacuum, confirming it holds before loading it.
Step 3
Use 50 KG for a panel lifted flat and 30 KG for one carried upright, with margin.
Step 4
Release the vacuum before storing and inspect the pad for hardening or grit.

FAQ
JS8641 Questions
Is this mechanically different from the standard JS8641?
No. Same aluminium alloy body, same 425 g, same 50 KG horizontal and 30 KG vertical ratings, same carton. The difference is the silver finish.
Why offer it as a separate model?
Because distributors build ranges around a consistent finish, and a silver lifter in a silver range sells better than a yellow one. It is a commercial distinction, not a technical one.
What other finishes are available?
Yellow, silvery and golden are stock on this body, and custom colours can be matched. Each finish counts toward the model's minimum.
How is it packed?
One piece per inner box, 30 pieces per master carton at 65 x 39 x 25 cm.
What is the minimum order quantity?
2,000 pieces for a customised version, per finish.
