Industrial-Grade Nylon Injection-Molded Bushing

Injection molding is designed for high consistency and stable volume production. With a mature production system and controlled processes, KT maintains dimensional accuracy and visual quality across batches, minimizing issues such as warpage, shrinkage, and color variation. For applications requiring scalable production and assembly compatibility, injection molding delivers reliable structural integrity and consistent appearance—ensuring efficient and controlled product delivery.

Injection Molding Process

1. Mold development: Design precision injection molds based on product structure, including stepped structure, inner wall forming and cooling systems
2. Material preparation: Dry modified nylon to control moisture content and prevent molding defects and bubbles
3. Injection molding: High temperature and high pressure injection molding, controlling injection pressure, temperature and holding time to ensure smooth inner wall and dimensional accuracy
4. Post-treatment: Remove gates and flash, cool and set, inspect dimensions and surface defects
5. Performance testing: Dimensional inspection, wear resistance testing, high and low temperature cycle testing, chemical corrosion resistance testing

Overall process: Precision Injection Molding Process, achieving high-precision mass production of bushings with smooth inner walls and stable dimensions by optimizing mold structure and molding parameters, meeting the strict requirements of industrial equipment for support component wear resistance and consistency.
