YFR carbon fiber heat lamps can be used in PET stretch-blow moulding equipment to heat preforms before bottle forming. The carbon emitter produces controllable infrared radiation inside a quartz tube and can be arranged in multiple heating zones around the preform path.
Preform heating is a process-balancing task: the lamp, reflector, oven airflow, rotation, line speed and zone settings work together. A carbon lamp should therefore be selected according to the machine and bottle process rather than treated as a universal drop-in substitute for every quartz halogen emitter.
The lamp supplies radiant energy to the preform wall before stretching and blowing. Heating zones can be adjusted to influence the temperature along the preform body, neck area and base transition. The objective is a repeatable preform temperature profile that supports stable bottle formation.
Carbon emitters may be considered when the preform material and oven design benefit from their output profile and lower visible brightness. Process trials are recommended when converting from another emitter type because the same percentage setting may not produce the same preform temperature.
| Item | Information to confirm | Reason |
|---|---|---|
| Machine and mould | Blowing-machine model, cavity count and bottle type | Defines the oven layout and production requirement. |
| Preform | Material, colour, weight and wall distribution | Influences absorption and temperature profile. |
| Electrical | Voltage, power and controller compatibility | Matches the lamp to the machine power system. |
| Dimensions | Total length, heated length and tube diameter | Confirms physical fit and zone coverage. |
| Reflector | Clear or directional coating and heating orientation | Controls where radiation is delivered. |
| Termination | Ceramic ends, cable, connector and lead direction | Matches the existing holder and wiring. |
After installation, begin with conservative zone settings and verify the preform temperature using appropriate measurement equipment. Adjust lamp output, airflow, preform rotation and oven residence time as a coordinated system. Bottle-wall distribution, haze, crystallization, gate condition and forming stability should be checked during validation.
Send the original lamp code, machine model, voltage, power, overall length, heated length, tube diameter, photos of both ends and connector details. If a reflector coating is used, mark the side facing the preforms. An undamaged sample or drawing is recommended for non-standard lamps.

Contact YFR for a carbon heat-lamp evaluation. Final lamp selection should be validated on the actual machine and preform.
