1.The hot plate welding width of lens is 1.50MM
2. The hot plate welding rib width of the housing is 2.4mm
3. The upper and lower parts’ hot plate welding ribs overlap is 2.4mm
4. The distance between the hot plate welding ribs and the decorative parts is more than 2.5mm
(Note: the limit distance through both ends of the long lamp is 3.5mm)
5. The distance between the hot plate welding ribs and the body is larger than 2.5MM
6. The maximum angle between the hot plate welding ribs and the welding direction cannot exceed 60 degree.
The current data welding ribs’sizes do not meet the hot plate welding. Welding rib width, overlap amount recommended in accordance with the standard design on the above guidance.
- Lamp lens welding rib material recommendation: PMMA
- Recommended welding rib material for lamp housing: ABS PC-ABS (PC content recommended to be less than 30%) ASA
Please contact us if you don’t want to use the above materials. - If the lens with PC material contact welding drawing serious, it is recommended to use non-contact welding, non-contact does not exist in the drawing problem
- At present, there is no turning over of the lamp housing, it is recommended to increase the turning over of the edge to facilitate the later correction of product deformation, the height of the turning over is more than 2.5mm.
- Pre-tensioned structure is added to the lamps for easy correction of product deformation.
