A cermet and/or ceramic multi-coloured article, and in particular a bezel (1) of a timepiece, produced by a method for compressing at least two materials (2, 3) of distinct colours, the article including a relief decoration (8) of a different colour from the rest of the article, the decoration (8) being produced by laser ablation on one of the materials (3) after compression of the two materials (2, 3).

A method and system for forming vertical wall construction units in one or more provided forms provides environmentally-manageable construction with reduced labor burden over existing non-traditional construction techniques. The method is a method of operation of the system, which includes a programmable controller, a reciprocating tamper head, a positioner that is guided to position the tamper head, and a filling mechanism for introducing loose material to a form in pre-determined layer volumes to provide loose material for individual layers of the prefabricated vertical construction unit. The programmable controller operates the filling mechanism to introduce the loose material for the current layer, then operates the three-axis positioner to guide the reciprocating tamper head over a horizontal cross-section of the form at a height determined for the current layer and along a program-determined path to compact the current layer. The process is repeated until the compacted material reaches a programmed height.

The proposed solution solves a problem of designing a machine for producing molded composite parts that are homogeneously structured and the problem of finding a method for producing composite for implants. The essence of the design of the machine consists in that it has a portioning assembly, whereby above a mold form unit (14) there is a guiding unit (11) located opposite a dosing unit (6) and above the aforementioned guiding unit (11) there is a pressing assembly (20) slidingly mounted on a vertical frame (19) and which is equipped with at least one piston rod (25) with a rammer (27) at its end. A preliminary molding is being performed by thoroughly filling a preform trough and then the matter is being pushed out of the preform trough in portions and then each portion is rammed separately until consistency containing less than 15% air is achieved.
