Key benefits
Why Buyers Choose This Model
225 mm Maximum Stroke
40 mm longer than the 400 ML version, matched to the longer 600 ml dual cartridge so the pack empties completely.
800 KG Thrust, Six Gears
Enough force for two-component grout through a mixer, with six gear settings so output suits the joint width rather than being fixed.
Intelligent Limit And Battery Display
The gun stops the rod at end of stroke instead of driving against it, and the operator can see the remaining charge before starting a long run.
LED Work Light
Standard, and more useful than it sounds on floor grouting where the joint is in the operator's own shadow.
Application scenarios
Where It Is Used
- Epoxy grouting with 600 ml two-component cartridges
- Large floor areas worked continuously
- Joint work in poor light
- Professional grouting crews needing full pack utilisation
Who it is for
The Buyers This Model Suits
Tiling Contractors On 600 ml Packs
Needs the longer stroke so the larger cartridge empties rather than jamming short.
Crews Grouting Daily
Powered dispensing is what makes a consistent bead sustainable across a shift.
Distributors Stocking Both Strokes
The 400 ML and 600 ML pair covers both cartridge lengths from one product family.
Problems it solves
What It Fixes
Short Stroke On A Long Cartridge
A 185 mm stroke leaves grout in a 600 ml pack. 225 mm is the reason this version exists.
Consistency Over Hours
Cruise control and a fixed gear setting hold the output while the operator's hands do not.
Working In Your Own Shadow
The LED light matters on floor work more than anywhere else.

Materials and manufacturing
How This Model Is Made
Parts for the JS8615-600ML 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.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.

Use guide
Getting The Best Out Of It
Step 1
Charge both batteries; a 1500 mAh pack takes 30 minutes.
Step 2
Fit the 600 ml dual cartridge and mixing nozzle with the rod fully retracted.
Step 3
Start on a low gear, test on scrap, then raise the setting until one pass fills the joint.
Step 4
Clean the nozzle seat before the two-component product cures, since cured grout is not removable.
