The invention discloses a toughening color master batch for high impact polystyrene, a composite board and a liner of refrigeration equipment. The toughening color master batch for the high impact polystyrene comprises the following components in part by weight: 25 to 85 parts of toughening agent, 10 to 50 parts of softener, 10 to 50 parts of base material and 5 to 35 parts of toner. According to the toughening color master batch for the high impact polystyrene, a carrier in a conventional color batch is replaced by the toughening agent, so that the toughening color master batch has the effect of toughening the high impact polystyrene in the process of dying the high impact polystyrene. According to the high impact polystyrene composite board, the strength is obviously improved, so that the thickness of the board can be reduced and the using amount of materials can be reduced; return material proportion in an extruded board material can be obviously improved, even the composite board can totally adopt a return material; by controlling the addition ratio of the toughening color master batch, the performance of the board can be regulated so as to meet different requirements; due to low density of the toughening color master batch, the weight of the liner formed by the composite board with the same size can be reduced.

This invention improves on the process of bending in a conventional progressive stamping press a flat laminated metal sheet around a corner edge of a die block to form a generally straight piece-part corner, and comprises the steps of forming extended concavely rounded depressions in the opposite sheet faces at the sheet locations of the intended corner, then locating and clamping the sheet with the depressed regions aligned along a die block corner, and then mechanically bending the sheet with said depressed sheet regions aligned over the die block corner edge. The sheet depressions can be aligned essentially opposite one another, being rounded concavely and of a high width-to-depth ratio and of a depth to reduce the sheet to between 80-30% of its original thickness. The sheet depressions might occur at one stamping press station by opposing press tools each having a convex rounded working edge elongated along the length of the intended corner, with the blank bending occurring at a subsequent stamping press station.
