Custom TPU coiled cable projects often fail at the sampling stage because the RFQ only says ??pring cable??or ??oiled cable??without enough measurable requirements. A supplier can quote a price, but the first sample may stretch too far, rebound poorly, feel too stiff, damage the connector end, or arrive in packaging that deforms the coil.
Quick Answer
Before sending an RFQ for a custom TPU coiled cable, buyers should confirm natural length, extended length, coil diameter, TPU hardness, cable OD, connector strain relief, testing method, packaging protection, quantity, and application environment. These details help the supplier quote the same product you expect to approve.
Why Buyers Search This
Buyers searching for custom TPU coiled cables usually already have a use case: outdoor equipment, EV accessories, trailer cables, industrial handheld devices, charging products, control handles, or retractable cable assemblies. The risk is that a cable that looks similar in photos can perform very differently after repeated stretching.
1. Stretch Length and Rebound
Define the relaxed length, working extension length, maximum stretch length, and acceptable rebound after use. If the rebound requirement is important, ask the supplier how the sample will be checked before approval.
2. Coil Diameter and Tail Length
The coil diameter, coil pitch, straight tail length, and connector exit direction affect storage, product appearance, and installation. These dimensions should be written in the RFQ instead of assumed from a photo.
3. TPU Material and Hardness
TPU material choice affects flexibility, abrasion resistance, oil resistance, cold-temperature behavior, and surface feel. If you do not know the hardness, describe the working environment and target flexibility so the supplier can recommend a practical option.
4. Cable OD and Internal Structure
Confirm cable outer diameter, conductor specification, shielding if needed, current or signal requirement, and whether the cable will be used for charging, signal, control, or mixed functions. These details affect price and sample feasibility.
5. Connector Strain Relief
The connector end is where many coiled cables fail first. Confirm connector model, molding shape, cable exit angle, bend protection, pull force expectation, and whether the cable will be frequently pulled sideways.
6. Testing Checklist
- Continuity and pinout check.
- Visual inspection of coil shape and jacket surface.
- Stretch and rebound review after repeated extension.
- Connector fit and strain relief check.
- Length and packaging inspection before shipment.
7. Packaging Mistakes
Poor packaging can deform the coil, scratch the jacket, bend connector ends, or mix labels between SKUs. Confirm bagging, coil fixing method, connector protection, carton quantity, label rules, and whether the buyer needs retail packaging or bulk export packaging.
What to Send in RFQ
Send drawing, sample photo, natural length, extended length, coil diameter, straight tail length, cable OD, connector type, TPU color, application, working environment, test expectation, packaging requirement, target quantity, destination market, and sample deadline.
