Key benefits
Why Buyers Choose This Model
420 KG Push Force
The highest figure in our catalogue, more than any manual sealant gun and more than any other grout gun here. It is the answer when a 200 KG gun stalls.
500 KG Maximum Tolerance
Also the highest frame figure we publish, giving a 19 percent margin at the very top of the range.
43:1 With Labour-Saving Linkage
The high ratio and the linkage device together keep the pull manageable despite the force, which is the only way 420 KG is a hand tool.
Welded Steel At 1000 g
Welded steel construction, which is what carries a 500 KG rating, at a kilogram.
Application scenarios
Where It Is Used
- The stiffest 1:1 epoxy and structural grout products
- Continuous professional grouting on large areas
- Cold-weather two-component work
- Top of a distributor's grout range
Who it is for
The Buyers This Model Suits
Heavy Grouting Contractors
Works through packs continuously with products that defeat lighter guns.
Cold-Climate Crews
Epoxy stiffens with temperature, and 420 KG is the margin that keeps it dispensing.
Distributors Needing A Ceiling
The strongest gun in the catalogue makes a credible top of range with a number nobody argues with.
Problems it solves
What It Fixes
Products That Stall A 200 KG Gun
420 KG is roughly double, which is the step change rather than an increment.
Frames Failing At High Force
A 500 KG tolerance is the only figure in the catalogue with that much absolute headroom.
Pull Weight At High Force
43:1 and the labour-saving linkage are why this remains a hand tool.

Materials and manufacturing
How This Model Is Made
Parts for the JS8615-3 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.
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.

Getting The Best Out Of It
Step 1
Confirm the cartridge is 1:1 before loading, since this gun will happily dispense a wrong-ratio product badly.
Step 2
Fit the static mixing nozzle and discard the first short length of mixed grout.
Step 3
Let the ratio and linkage carry the load; at 420 KG, forcing the trigger achieves nothing.
Step 4
Clean the plunger seat and nozzle mount before the epoxy cures on them.

Choosing A Two-Component Gun By Mix Ratio
The ratio is built into the gun's linkage, so a 1:1 gun cannot dispense a 1:4 product. Match the gun to the cartridge, every time.
