Product Overview
The thickened-plunger sausage model: 150 KG push force at 20:1 with a 170 KG structural tolerance, in a 465 g gun. Barrel is modified enhanced polypropylene rated to 65 KG with a glossy grip section and a transparent window, and the gun carries thick alloy components and the latest-generation handle.
Key benefits
Why Buyers Choose This Model
150 KG At 465 g
The thickened plunger raises push force from the JS-8631's 120 KG to 150 KG and tolerance to 170 KG, at almost the same weight.
20:1 With A Transparent Barrel
A high dispensing ratio for faster completion, combined with a transparent barrel section so the operator can monitor the adhesive level as they work.
Thick Alloy Components
Alloy rather than pressed parts at the load points, which is what lets a 465 g polypropylene-barrelled gun hold 170 KG.
Two Registered Patents
Safeguarded by two patented technologies covering the self-locking mortise and tenon structure, so this configuration is only available from us.
Application scenarios
Where It Is Used
- Heavy structural adhesive from sausage packs
- Facade and panel bonding at reach
- Cold-weather structural work
- Top of a patented own-brand range
Who it is for
The Buyers This Model Suits
Structural Bonding Crews
Works with the stiffest sausage-packaged products and needs the force without the weight of an aluminium gun.
Buyers Comparing On Force-To-Weight
150 KG from 465 g is difficult to match with a conventional mechanism at any price.
Own-Brand Programmes
Wants the strongest patented model as the visible ceiling of a branded range.
Problems it solves
What It Fixes
Stiff Adhesive From A Light Gun
The patented plunger is how the two requirements coexist, rather than being traded against each other.
Adhesive Level Unknown Mid-Run
The transparent barrel section removes the guesswork on a structural joint that cannot be interrupted.
Structural Load On A Plastic Barrel
The barrel is rated to 65 KG in its own right and the alloy components carry the 170 KG frame load.

Materials and manufacturing
How This Model Is Made
Parts for the JS8631-2 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.
- Multi-Colour Logo Printing: Paint screen printing in any colour, with several colours printed at once.
- Tag And Product Screen Printing: Screen printed tags and product markings, multi-colour capable.

Step 2
Check the transparent window before committing to a long run.
Step 3
Squeeze to full stroke end each time so the thickened plunger locks properly.
Step 4
Use the drip prevention function at every pause, and grip the barrel at the glossy section.
