FIELD: process engineering.
SUBSTANCE: proposed method comprises cutting of sheets from wear and shock resistant thermoplastic material on preliminary made patterns. After cutting, aforesaid sheets are arranged on a carcass and subjected to thermal treatment to produce 3D relief surface thereon. Now the carcass is withdrawn, or not withdrawn, to joint sheet edges together to make a rigid casing. The carcass, or casing inner, holes made therein accommodate lamps with harness laid in folds of projecting spaces. Thermal treatment can be effected both manually and mechanically with the help of thermal chamber. Aforesaid sheets are jointed together by clips, by ultrasound welding of thermal welding.
EFFECT: higher quality, possibility to use in various ambient conditions.
