Q: Can Kinki machines integrate automation?
Yes. Robotic arms and rotary table systems can be integrated for continuous and unmanned production.
How Does Cable Overmolding Work?
Cable overmolding is a process that encapsulates cable joints or connectors with thermoplastic or elastomer material using injection molding technology. The process begins by placing a pre-assembled cable and connector into a mold cavity. Once the mold is closed, molten material—typically PVC, TPU, or TPE—is injected to form a protective layer around the connector.This layer provides:
- Mechanical strength and strain relief
- Moisture and dust sealing
- Electrical insulation
- Enhanced appearance and branding options
Using vertical injection molding machines improves positioning accuracy and ensures that cables remain fixed during molding, resulting in consistent product quality.
