Why Glue Stick Diameter Matters
The diameter of a hot melt glue stick must match your glue gun chamber. Using the wrong size causes feeding jams, uneven melting, or weak bonds. Jiajian supplies glue sticks in 7mm, 11mm, 15mm, 18mm, 24mm, and 43mm diameters to fit everything from craft guns to industrial extruders.
7mm Glue Sticks: Precision and Light Duty
The 7mm stick is the smallest standard size, designed for low-power mini glue guns (10-20W). It is ideal for electronics assembly, model making, jewelry repair, and fine crafts where control and a thin adhesive line matter more than raw output. Because the gun melts less material at a time, 7mm sticks reduce waste on small jobs.
Typical uses
- PCB wire tacking and component bonding
- DIY crafts, school projects, floral work
- Small household and hobby repairs
11mm Glue Sticks: The All-Round Standard
The 11mm stick is the most common size worldwide and fits standard 40-60W glue guns. It delivers a stronger flow for woodworking, packaging, product assembly, and general factory use. If you run mixed applications, 11mm is usually the safest default.
Typical uses
- Carton sealing and packaging lines
- Wood, plastic, and metal bonding in assembly
- Display, signage, and trade-show build
How to Choose
