122 122
- For tricky materials like nylon or TPU, use **heat welding**, **mechanical fasteners**, or **special plastic adhesives**
123 123
124 124
125
+## For high-strength bonding of mechanical transmission components (e.g., gears, bearings, linkages, metal or hard plastic parts), the recommended adhesives are:
126
+
127
+| Adhesive Type | Suitable Materials | Features & Recommendations |
128
+|----------------------------|-----------------------------------|----------------------------------------------------------------------------|
129
+| AB Glue (Epoxy Resin, 2-part) | Metal, ceramics, hard plastics, composites | Extremely strong, gap-filling, rigid after curing, heat and chemical resistant, good for shear and pressure loads |
130
+| MMA Adhesive (Methyl Methacrylate) | Metal, composites, hard plastics | Industrial-grade, strong and slightly flexible, vibration-resistant, suitable for high-speed or vibrating environments |
131
+| Structural Acrylic Adhesive | Metal-to-metal, composites | High shear strength, commonly used in automotive or mechanical structural parts |
132
+| PU Adhesive (Polyurethane Structural Glue) | Metal, hard plastic, composites | Flexible, absorbs vibration, good for impact or minor vibration, slightly lower strength than AB glue |
133
+
134
+⚙️ **Selection Recommendations**:
135
+1. **High load, requires rigidity** → **AB Glue (Epoxy Resin)**
136
+2. **High load with vibration or impact** → **MMA Glue / Structural Acrylic**
137
+3. **Moderate load, requires flexibility, minor vibration absorption** → **PU Structural Glue**
138
+
139
+💡 **Tips**:
140
+- Ensure bonding surfaces are **clean, dry, and oil-free**
141
+- Lightly sanding metal or hard plastic surfaces can improve friction and adhesion
142
+- For high-speed rotating or precision transmission components, even after curing, **stress distribution** should be considered; using **mechanical alignment pins/bolts** can reinforce the joint
