Adhesive Bonding

Expert in Precision Bonding Across Different Materials · Perfect Integration with Plastic Injection Molding and Silicone Rubber Molding Industries

With over 30 years of experience in material processing, FKX provides professional adhesive backing and multi-material bonding solutions for plastic panels, metal nameplates, silicone and rubber components. For extreme environments and special applications, we precisely match adhesive materials from international leading manufacturers to ensure excellent bonding strength and long-lasting durability.


Why Choose FKX for Adhesive Bonding and Composite Processing?

  • Professional Solutions for Difficult-to-Bond Silicone Rubber Materials: Silicone and rubber materials (such as EPDM, NBR, and silicone rubber) have low surface energy and are extremely difficult to bond. We have expertise in professional surface modification technologies, such as primer application and surface activation, to effectively overcome low-surface-energy bonding challenges and achieve strong and durable bonding.
  • Deep Integration with the Injection Molding Industry: We seamlessly integrate post-processing for plastic injection molding and silicone rubber molding. Whether it involves bonding injection-molded parts with metal nameplates, applying adhesive backing to silicone rubber buttons and panels, or composite bonding of soft and rigid materials, we provide one-stop integrated processing solutions.
  • Carefully Selected Adhesive Materials from International Brands: We comprehensively utilize industrial double-sided tapes and specialty adhesive materials from leading international brands such as 3M, NITTO, and TESA. Based on the material characteristics of the customer's products, the flatness of the bonding surfaces, and budget requirements, we provide recommendations for the most suitable adhesive materials.
  • Durability for Harsh Operating Conditions: For special application environments involving high temperatures, high humidity, outdoor UV exposure, chemical solvent corrosion, or high-intensity vibration, we strictly conduct weatherability and adhesion tests to ensure that products do not experience adhesive failure, adhesive overflow, or bubbling.

Main Application Fields and Products

  • Electronic and Home Appliance Panels: Adhesive backing for PC/PET control panels, and double-sided adhesive tape bonding for dustproof and waterproof touchscreens.
  • Industrial and Automotive Nameplates: Strong adhesive bonding of stainless steel and aluminum nameplates to plastic housings or vehicle bodies.
  • Silicone Rubber Buttons and Sealing Components: Adhesive backing for silicone buttons used in electronic products, and adhesive backing treatment for rubber sealing gaskets used in automobiles and motorcycles.
  • Multi-Material Composite Components: Buffering and fixing components combining multiple materials, such as metal + silicone rubber and plastic + rubber.
  • Medical and Cultural & Creative Products: Medical-grade silicone bonding and processing of high-temperature-resistant and antibacterial silicone rubber products.

  • High-Precision Bonding Processing: Utilize positioning fixtures and automatic/semi-automatic bonding equipment to ensure smooth, bubble-free bonding.
  • Die-Cutting and Precision Punching: Perform high-precision digital die-cutting or punching according to drawings, ensuring smooth edges without adhesive overflow.
  • 100% Inspection and Fast Delivery: Conduct 100% visual and dimensional inspection, with completion and delivery within 7–10 working days.

Frequently Asked Questions (FAQ)

Q: Why does silicone rubber products require special adhesive backing treatment?

A: Silicone rubber is a low-surface-energy material by nature, and ordinary double-sided adhesive tape cannot bond firmly to it directly, making it prone to detachment over time. FKX uses a specialized primer for surface activation treatment, enabling the adhesive tape to form strong chemical bonds with the silicone rubber molecules and solving adhesive failure problems.

Q: Can you bond plastic injection-molded parts with textured or curved surfaces?

A: Yes. For injection-molded parts with rough surfaces, micro-textures, or slight curves, we recommend pressure-sensitive adhesives (PSA) with thicker adhesive layers or high-performance foam adhesive tapes (such as the 3M VHB series) to fill small gaps on the surface and achieve optimal bonding performance.

Q: Can you provide customized die-cut shapes?

A: Absolutely. We have precision die-cutting and punching equipment that can precisely die-cut adhesive backing into various complex shapes according to your CAD/AI design drawings, making it convenient for rapid assembly on your production line.
