FAQ

Q1:What is an overmolded cable?

A:An overmolded cable is a type of cable assembly where the connector and cable junction are encased in a single, seamless layer of molded thermoplastic or rubber material. This manufacturing process creates a durable, strain-relieved, and environmentally sealed connection that is highly resistant to moisture, dust, vibration, and pulling forces. The result is a robust and reliable cable ideal for demanding applications in consumer electronics, automotive, industrial equipment, and medical devices, where long-term durability is critical.

Q2:How to bind cables together?

A:There are several effective methods to bind cables together. Common solutions include using hook-and-loop (Velcro) straps for reusable flexibility, plastic zip ties for a permanent and secure hold, or adhesive-backed cable clips for routing along surfaces. For a professional and protected finish, especially with multiple cables, expandable braided sleeving or spiral wrap offers excellent organization and abrasion resistance. Always avoid overtightening to prevent damaging the cables.

Q3:How are molded cables made?

A:Molded cables are manufactured through a process called injection molding. First, the cable and connector are assembled. Then, they are placed into a custom mold cavity. Molten thermoplastic or rubber material is injected under high pressure into the mold, completely surrounding the critical junction. After cooling and solidifying, the mold opens to reveal a finished, seamless product. This creates a durable, strain-relieved, and environmentally sealed unit that is highly resistant to moisture, dust, and pulling forces, making it ideal for consumer electronics and industrial applications.
