JS8630 Patented Self-Locking Glass Adhesive Gun (Designed for Bottle-Packaged Glass Adhesive)
The bottle-pack member of the patented family: a self-locking mortise and tenon plunger delivering 120 KG push force from a 400 g gun at 20:1, with a 150 KG plus or minus 5 KG structural tolerance.
Product Overview
The bottle-pack member of the patented family: a self-locking mortise and tenon plunger delivering 120 KG push force from a 400 g gun at 20:1, with a 150 KG plus or minus 5 KG structural tolerance. The frame is a sturdy four-point weld, the handle is enhanced polypropylene and rotates through 360 degrees.
Key benefits
Why Buyers Choose This Model
Self-Locking Mortise And Tenon Plunger
The plunger locks to the rod at each stroke instead of gripping by friction, which delivers greater dispensing force than a conventional gun of the same size. Covered by our own registered patents.
360-Degree Rotating Handle
The handle rotates a full turn, so the gun can be worked into a corner or along an awkward joint without the operator's wrist following it.
Four-Point Welded Frame
A sturdy four-point welding process on the gun body frame, which is what carries the 150 KG structural load against the 120 KG working force.
Three Colour Options
White and yellow in stock with three colour options available, on an enhanced polypropylene handle that is both durable and comfortable.
Application scenarios
Where It Is Used
- Glass adhesive from 300 ml bottle packs
- Corner and awkward-angle joints needing a rotating handle
- Own-brand ranges needing a patented model
- Applications where force matters but weight cannot
Who it is for
The Buyers This Model Suits
Glazing Contractors
Applies bottle-packaged glass adhesive and needs force from a gun light enough to hold at arm's length.
Distributors Wanting Exclusivity
The mechanism is patented to us, so this model is not available from other factories.
Crews Working In Corners
The 360-degree rotating handle is the feature that matters when the joint is not where the operator's wrist wants to be.
Problems it solves
What It Fixes
Force Lost At The Plunger
A conventional plate slips slightly on the rod under load and wastes part of every squeeze. The mortise and tenon lock removes that.
Competing On A Generic Gun
Anyone can source a standard frame. A patented mechanism gives a distributor something to defend.
Wrist Position In Corners
A fixed handle forces the operator to rotate the whole gun. This one rotates on its own axis.

Materials and manufacturing
How This Model Is Made
Parts for the JS8630 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.
Use guide
Getting The Best Out Of It
Step 1
Load the bottle pack with the rod fully retracted so the self-locking plunger seats correctly.
Step 2
Rotate the handle to the angle the joint needs before you start, not halfway through.
Step 3
Squeeze fully to each stroke end, since the locking action engages at the stroke rather than continuously.
Step 4
Use the drip prevention function at pauses to avoid wasting adhesive.
Comparison
How It Compares In Our Range
The patented family is four models: two pack formats, each in standard and thickened-plunger versions.
| JS8630-2 | The thickened-plunger version: 150 KG at 405 g with a 180 KG tolerance and a 16:1 ratio. |
|---|---|
| JS-8631 | The sausage-pack equivalent at 120 KG and 25:1, with a transparent barrel section. |
| JS-8605 | A conventional welded gun at 160 KG and 520 g, if a patented mechanism is not the point. |
FAQ
JS8630 Questions
What is the self-locking mortise and tenon structure?
A plunger that locks mechanically to the push rod at each stroke instead of relying on friction. Less force is lost at the plunger, so a 400 g gun delivers 120 KG. It is covered by our own registered utility model patents.
Which patents cover it?
Chinese utility model 202321512117.9 covers the self-locking mortise and tenon caulking gun and 202321498230.6 covers the silicone gun. The company holds five utility model patents and one invention patent in total.
What pack does it take?
Bottle-packaged glass adhesive, meaning standard 300 ml cartridges. The JS-8631 models are for sausage-packaged structural adhesive.
What are the ratings?
120 KG push force, 150 KG plus or minus 5 KG maximum tolerance, 20:1 drive ratio, 400 g net weight.
How is it packed?
One piece per poly bag, 20 pieces per master carton at 52 x 24 x 23 cm. Minimum order 2,000 pieces customised.
