How to Choose the Right Dual Cartridge

  • Mix Ratio Requirements: Choose a cartridge that matches the adhesive’s required mix ratio, to maintain accurate component proportioning during dispensing.
  • Cartridge Capacity: Select the appropriate cartridge volume based on dispensing output, production cycle, and material consumption requirements.
  • Material Selection: PBT, PA, and PP dual cartridges are available for different adhesive chemistries and dispensing conditions. Material selection should consider chemical resistance, strength, and application environment.
  • Piston Structure: Vented pistons are suitable for rear-fill processes by releasing trapped air during filling, while non-vented pistons provide a fully sealed structure after filling. Pistons with sealing rings help reduce leakage for low-viscosity materials, while pistons without sealing rings can lower dispensing resistance for high-viscosity adhesives.

Structural Bonding and Assembly of Dual Cartridge Gun

Automotive & Transportation

Our dual chamber cartridges are used for dispensing two-component structural adhesives suitable for bonding and repairing metal components in mechanical manufacturing. These applications often require resistance to high mechanical loads and harsh operating conditions. When dispensing in scenarios subject to vibration or dynamic loading, controlled dispensing systems combined with two-part cartridges help maintain stable flow characteristics during longer dispensing cycles.

Electronics and Encapsulation of Dual Cartridge Gun

Electronics & Electrical

Small-capacity dual cartridges are used to house two-part potting compounds for delicate circuit protection, including the fixing and encapsulation of electronic components, providing excellent insulation and weather resistance. For precision dispensing in connector sealing and strain relief applications, a dual barrel syringe offers an ideal solution. When paired with manual or pneumatic applicators, these systems facilitate a steady, intended mix.

Frequently Asked Questions About Dual Cartridge

What capacity ranges and mix ratios are supported by dual chamber cartridges?

−

The dual chamber cartridge is available from 50 ml to 1500 ml. Available mixing ratios include 1:1, 2:1, 3:1, 4:1, 5:1, and 10:1 for different adhesive and dispensing applications. In actual production, ratio accuracy is often affected by mismatches between dispensing guns, pistons, and static mixers rather than the cartridge body itself. As professional dual chambers cartridge manufacturers, Btektech can also support customized cartridge configurations based on filling systems, dispensing requirements, and adhesive properties.

How do PP, PA and PBT materials affect dual cartridge performance and limitations?

+

When should vented pistons be selected instead of non-vented pistons?

+

How do sealing-ring pistons compare to on-sealing pistons during dispensing?

+

How should side-by-side and coaxial dual cartridges be chosen for applications?
