    • A method for making recessed tray liners for storing objects in a storage container is disclosed. The first step in the method is to size a structural thermoplastic foam liner to fit within a tray. The foam liner is preferably a foamed polyethylene plastic. After the tray is lined with the foam liner, the object or objects to be held in the tray are then heated to a temperature sufficient to soften the thermoplastic foam. The temperature of the heated object is selected to be above the softening temperature of the thermoplastic foam, but below the melting temperature of the foam. After the object or objects have reached the appropriate temperature, the heated object is pressed into the foam lining to form a cavity. The heated foam will flow such that the cavity will conform to the contours of the object being pressed into the foam. After the object is sufficiently pressed into the foam, it is rapidly cooled to a temperature below the softening temperature of the foam. Preferably, the cooling is achieved by quenching the object with a fluid having a temperature lower than the softening temperature of the foam. Water is a suitable cooling fluid.
    • 公开了一种用于制造用于将物品存储在存储容器中的凹进式托盘衬里的方法。 该方法的第一步是将结构热塑性泡沫衬里的尺寸设置成适合托盘。 泡沫衬垫优选为发泡聚乙烯塑料。 在托盘衬有泡沫衬垫之后,待保持在托盘中的物体然后被加热到足以软化热塑性泡沫的温度。 加热物体的温度选择为高于热塑性泡沫的软化温度,但低于泡沫的熔融温度。 在物体或物体达到适当的温度之后,加热的物体被压入泡沫衬里以形成空腔。 加热的泡沫将流动,使得空腔将符合被压入泡沫体中的物体的轮廓。 在将物体充分压入泡沫中之后,将其快速冷却至低于泡沫的软化温度的温度。 优选地,通过用温度低于泡沫的软化温度的流体淬火物体来实现冷却。 水是合适的冷却液。
