YFR special-shape infrared lamps are designed for components that cannot be heated effectively with a straight emitter. The quartz tube can follow an edge, corner, opening or curved working zone so radiant energy is delivered close to the area that needs heating.
This approach is useful for automotive plastic parts, formed textiles and other three-dimensional products. The emitter contour, filament position and reflector direction are developed from the part geometry and process requirement rather than selected from a standard straight-lamp list.
Depending on the bending radius, quartz section and electrical design, shapes such as O, U, omega, angled, curved and multi-segment emitters can be evaluated. A special shape must leave sufficient room for the quartz envelope, filament supports, cold ends and electrical connections. Not every drawing can be manufactured exactly as submitted, so a design review is required before tooling or production.
| Application | Heating objective | Design information |
|---|---|---|
| Vacuum laminating | Preheat adhesive or surface layers along a shaped edge | Part contour, laminate width and cycle time |
| Plastic welding or joining | Heat a defined joining line before pressure or assembly | Joint geometry, polymer type and target zone |
| Thermoforming | Apply additional heat to corners or difficult draw areas | Sheet material, mould contour and forming sequence |
| Edge wrapping | Activate adhesive around a curved component | Edge path, working distance and line speed |
| Plastic deburring | Apply controlled heat to a local surface feature | Part material, burr position and exposure time |

For a new emitter, YFR reviews the heated contour and proposes a feasible lamp centreline, bending radius, filament zone and electrical connection. A prototype or process trial may be required before a production quantity is confirmed.
For a replacement, provide an undamaged sample, drawing, original code and photos showing how the lamp sits relative to the part. The lamp shape should not be copied from a photograph alone because camera perspective can distort dimensions.
