JS-8602 9" iron handle silicone rod frame skeleton gun

Product Overview

An iron and aluminium frame gun at 285 g that more than doubles the push force of the PP model it replaces, from 50 KG to 120 KG, at a 17:1 drive ratio. It keeps the frame-style open body and the 50-per-carton packing, so the freight economics survive the upgrade.

Key benefits

Why Buyers Choose This Model

120 KG From A 285 g Gun

Iron and aluminium construction instead of injection-moulded plastic, which is where the force comes from. Maximum tolerance is 130 KG.

Frame-Style Open Body

The open rod frame keeps weight down and lets the operator see how far the cartridge has emptied without pulling it out.

17:1 For Force Over Speed

A lower drive ratio than the economy model, which puts more of the squeeze into pressure. Suited to sealant that has stiffened in storage.

Still 50 Pieces Per Carton

Same 36 x 36 x 30 cm carton as JS-8601, so a mixed pallet of the two models loads cleanly.

Application scenarios

Where It Is Used

  • General glass adhesive work across a range of sealants
  • Trade counter sales to jobbing builders
  • Budget-conscious contract work needing more than an economy frame
  • Mixed retail ranges needing a visible second tier
Who it is for

The Buyers This Model Suits

Trade Counters

Serves customers who found the economy gun too light but will not pay for a welded professional body.

Building Material Retail

Needs a credible middle tier between an economy gun and a professional one, differentiated by material rather than colour.

Contractors On Price

Buys in quantity for general sealing and values the force step over refinement.

Problems it solves

What It Fixes

An Economy Frame That Flexes

PP frames give under a stiff cartridge and the bead goes uneven. Iron and aluminium at 120 KG removes that at a small cost increase.

Too Big A Jump In Price

Going straight from an economy gun to a welded professional body is a large step. This model fills it.

Not Knowing How Much Is Left

The open frame shows the cartridge, so the operator can judge whether there is enough for the next joint.

Materials and manufacturing

How This Model Is Made

Parts for the JS-8602 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

Check the rod is fully retracted before the cartridge goes in.

Step 2

Seat the cartridge against the front plate so the nozzle is square to the frame.

Step 3

Work at a constant travel speed; at 17:1 the bead responds more to speed than to grip pressure.

Step 4

Twist the rod to release pressure before setting the gun down mid-cartridge.

Step 5

Keep the rod clean of cured sealant, since a dirty rod is the first thing that makes a frame gun feel stiff.

FAQ

JS-8602 Questions

How much stronger is this than the PP model?

120 KG push force against 50 KG, with a 130 KG maximum tolerance against 60 KG. The construction changes from injection-moulded PP to iron and aluminium.

What is the difference between this and JS-8603?

Guides That Cover This Model

How To Read Caulking Gun Force Ratings

Push force, maximum tolerance and drive ratio describe three different things. Confusing them is the most common reason a gun fails in the field.

Cartridge Or Sausage Which Sealant Gun To Stock

Sausage packs cut cost per litre and packaging waste; cartridges are simpler and universally stocked. The right answer depends on who your customer is.
