China’s Top 10 Dual-Cartridge (AB Adhesive) System Suppliers – 2025

China’s Top 10 Dual-Cartridge (AB Adhesive) System Suppliers – 2025

Precision Packaging for 50ml, 200ml & 400ml Two-Part Adhesives in the Chinese Market

In China’s rapidly evolving adhesive landscape—fueled by electric vehicles, smart manufacturing, infrastructure upgrades, and DIY home improvement—the demand for reliable, user-friendly dual-component (AB) cartridge systems has never been higher. Whether it’s a 50ml mini-cartridge for smartphone repair, a 200ml standard for industrial bonding, or a 400ml high-capacity tube for construction sealants, the dual-cartridge is the backbone of modern two-part adhesive delivery.

Unlike single-barrel packaging, AB cartridges must ensure perfect volume ratio accuracy (typically 1:1, 2:1, or 10:1), leak-proof separation, material compatibility, and seamless integration with static mixing nozzles and dispensing guns. In 2025, Chinese manufacturers have moved far beyond basic injection molding—they now offer engineered solutions with barrier layers, anti-drip valves, color-coded chambers, and eco-friendly materials.

Based on production capability, material science expertise, OEM partnerships, quality control systems, and market penetration across electronics, automotive, construction, and retail channels, we present the Top 10 Dual-Cartridge (AB Glue Cartridge) Suppliers in China – 2025.

The 2025 Ranking: Leaders in AB Cartridge Innovation 1. Gauer Chemical (Shanghai) Co., Ltd.

1. Ningbo Angong Automation Equipment Co., Ltd.

Vertical Integration from Resin to Finished Cartridge

Angong operates its own HDPE compounding line and cleanroom molding facility, enabling full control over material purity and dimensional stability. Specializes in high-viscosity-compatible cartridges with reinforced pistons that resist buckling during dispensing. Supplies 200ml/400ml systems to major Chinese sealant brands like Baiyun and Sika China.

Edge: In-house R&D on barrier resins prevents amine migration in epoxy systems.

2. Shenzhen Ailepai Electronics Technology Co., Ltd.

Micro-Cartridges for High-Tech Electronics

Ailepai dominates the 50ml segment with ultra-clean, ESD-safe cartridges for thermal conductive epoxies and chip-underfill adhesives. All units are molded in ISO Class 8 environments, packed in anti-static bags, and tested for moisture vapor transmission rate (MVTR). Supports NDA-protected private labeling for semiconductor clients.

Niche leadership: Where precision matters more than volume.

3. Suzhou FlowTech Precision Components Co., Ltd.

OEM-Focused Engineering Partner

FlowTech rarely sells under its own brand but is the hidden supplier behind many premium adhesive brands. Its multi-cavity molds achieve ±0.1mm dimensional tolerance, ensuring perfect fit with international dispensing guns (e.g., Pail, Cox, SEM). Offers custom chamber ratios beyond standard 1:1 or 10:1—including 4:1 for specialty polyurethanes.

Strength: Deep collaboration with adhesive formulators during product development.

4. Dongguan Jiajia Composite Materials Co., Ltd.

High-Volume Producer for Mass Markets

Jiajia produces over 10 million AB cartridges annually, primarily 200ml and 400ml formats for construction and hardware sectors. Uses food-grade HDPE and offers low-cost color customization (e.g., blue/red chambers). Recently launched recycled-content cartridges (30% PCR) certified under China RoHS.

Value play: Reliable performance at competitive pricing for regional brands.

5. Yiwu Jiechuang Adhesives & Packaging Co., Ltd.

The DIY & Retail Channel Specialist

Jiechuang excels in consumer-ready kits: 50ml and 200ml AB cartridges bundled with reusable guns, mixing nozzles, gloves, and instruction cards. Popular on Pinduoduo, Taobao, and cross-border platforms like Temu. Features easy-peel foil seals and ergonomic finger grips for non-professional users.

Market insight: Understands that usability drives repeat purchases in the DIY segment.

Key Market Trends in China’s AB Cartridge Sector (2025)

• Ratio Diversification: Beyond 1:1 and 10:1, demand grows for 2:1, 4:1, and even 9:1 ratios tailored to new formulations.
• Eco-Regulations: China’s updated GB/T standards now encourage recycled content and restrict certain plasticizers.
• Smart Packaging: QR codes linking to SDS, application videos, and reorder portals are becoming standard on premium cartridges.
• Miniaturization: 50ml cartridges grew 55% YoY in 2024, driven by electronics repair and prototyping labs.
• Private Label Boom: Over 60% of mid-tier adhesive brands now outsource cartridge production to focus on marketing and distribution.

How to Choose the Right AB Cartridge Supplier in China

Consider these criteria:

• Material compatibility: Does the resin resist your adhesive’s chemistry (e.g., amines, acids, solvents)?
• Ratio accuracy: Is the internal divider wall precisely molded to maintain volume consistency?
• Gun compatibility: Will it fit standard manual/pneumatic guns (e.g., 300ml/400ml industry norms)?
• Cleanliness: For electronics/medical, is molding done in controlled environments?
• Sustainability: Can they provide PCR content, recyclability data, or carbon footprint reports?

Conclusion: The Cartridge Is No Longer Just a Container—It’s a Performance Enabler

In 2025, the dual-component cartridge has evolved into a mission-critical component of the adhesive value chain. Chinese suppliers are no longer passive packagers—they are co-engineers who ensure shelf stability, dispensing reliability, and end-user satisfaction. From Shenzhen’s micro-electronics labs to Inner Mongolia’s wind farms, the right AB cartridge makes the difference between a bond that lasts decades—and one that fails on day one.

As China pushes toward high-quality manufacturing and green transformation, the companies on this list are proving that even the most “invisible” packaging can drive visible innovation.
