Manufacturing Capabilities and Customization by GoodBon
GBA offers versatile manufacturing capabilities such as:
- Extrusion: For continuous production of profiles, suitable for large quantities of custom shapes.
- Molding: Ideal for creating specific designs in high volumes, including high-precision components.
- Die-cutting: Allows for the production of precise parts, typically for gaskets, seals, and other flat components.
- Overmolding with Metal Parts: This allows combining elastomeric materials with metal inserts, providing a dual function for grounding and shielding, improving mechanical performance, and ensuring strong bonding between metal and rubber parts.
These processes are adaptable to both mass production and small batch orders for engineering design variations, offering customers flexibility in manufacturing based on their specific needs, whether they are optimizing for performance or cost.
In summary, the selection of materials such as the EC2320 for aerospace or the EC2110 for commercial applications is driven by the balance between technical performance (e.g., shielding, conductivity, corrosion resistance) and economic considerations (e.g., cost, weight). The versatility of GBA’s manufacturing processes ensures that these materials can be customized and produced to meet both large-scale and niche application needs.
