Special-Shaped Infrared Lamps
Custom U-shaped, circular, curved, loop and spiral infrared emitters designed around special heating areas, machine layouts and non-standard industrial equipment.
Infrared emitters shaped around the required heating area
Straight infrared lamps work well for linear heating zones, but some machines require energy around a circular component, inside a compact chamber or across a curved product surface.
Special-shaped lamps can be designed to follow the equipment geometry more closely, helping position the heating element around the required area rather than forcing a straight emitter into an unsuitable space.
Shape alone does not define the complete lamp. Voltage, wattage, quartz diameter, heating technology, bending radius, reflector direction, active zones and terminals must all be considered together.

Submit Project Information →From heating concept to prototype lamp
Special-shaped lamps normally require more technical review than straight standard emitters.
Project Review
Review the machine, material, required heating result, electrical supply and available installation space.
Geometry Confirmation
Confirm dimensions, bends, radius, active zones, reflector direction and electrical connection points.
Technical Evaluation
Review whether the requested geometry is compatible with quartz forming and the selected heating technology.
Prototype & Testing
Produce and evaluate samples before confirming larger production quantities for a new custom design.
Select the infrared technology separately from the lamp shape
A U-shaped or circular lamp can still use different heating technologies depending on response and wavelength requirements.
Short-Wave Infrared
Fast-response, high-intensity heating for selected compact or cyclic industrial processes.

A special-shaped lamp drawing should show the complete geometry and the relationship between heated areas, cold zones, bends and electrical connections.
- Overall width, height and depth
- Outside and centre-line bending radius
- Quartz tube diameter or twin-tube cross-section
- Length of each straight section
- Location of every active heating area
- Cold-zone lengths near seals and terminals
- Angle and orientation of each bend
- Terminal, ceramic end and lead-wire positions
Direct infrared energy along a curved heating path
For reflector-coated shaped lamps, the drawing should clearly identify which side of every curved and straight section faces the product.
Information required to evaluate a custom-shaped infrared lamp
The more complete the drawing and application data, the more accurately the lamp can be reviewed.

Special-shaped infrared lamp design and development
What is a special-shaped infrared lamp?
It is a quartz infrared emitter formed into a non-standard geometry such as a U shape, circle, loop, curve or spiral. The shape is normally selected to match the heating area or available machine space.
Which lamp shapes can be customized?
U-shaped, circular, omega, loop, curved and selected spiral configurations can be reviewed. Feasibility depends on quartz diameter, bending radius, heated length and internal construction.
Can a special-shaped lamp use short-wave or medium-wave infrared?
Yes. The shape and wavelength are separate design decisions. Short-wave, medium-wave and selected carbon-element constructions can be reviewed according to the process requirement.
Can you work from a STEP or CAD drawing?
Technical review can begin from STEP, CAD or dimensioned PDF drawings. Important dimensions should still be clearly marked, including bending radius, active zones and terminal positions.
Can an old shaped lamp be reproduced?
An old sample, photographs and machine information can support replacement evaluation. Voltage, wattage, dimensions, reflector and operating conditions should also be confirmed.
Can a shaped lamp have a gold or white reflector?
Reflector-coated shaped lamps can be reviewed. The reflector direction must be clearly identified along every straight and curved section of the lamp.
Is there a minimum order quantity for special-shaped lamps?
Minimum quantity depends on the geometry, tooling, material use and production complexity. It can only be confirmed after the technical design has been reviewed.
Is prototype testing recommended?
Yes. Prototype testing is recommended for new shapes and new heating applications because mechanical fit and thermal performance must both be verified.
Can these lamps be used in vacuum equipment?
Selected vacuum-equipment projects can be reviewed, but suitability depends on the required vacuum level, materials, sealing method, electrical connections, operating temperature and equipment validation.
