välisk

Výlisk, sometimes written výlisek, is a term used in Czech and Slovak manufacturing to denote a component produced by punching or stamping from sheet material in a die. The part is typically created in high-volume production and may be used as a final component or as an intermediate piece in an assembly. The concept is common in mechanical engineering and sheet-metal fabrication.

Production and processing

A výlisk is produced in a stamping press equipped with a die set. The process can involve blanking, where a flat blank is cut from a sheet, or forming operations such as bending, drawing, or piercing to achieve the desired shape. Complex geometries may require multiple forming stages and secondary operations, including deburring, trimming, or coining. After forming, parts may undergo finishing steps such as coating, galvanizing, painting, or heat treatment, depending on requirements.

Materials and variations

Sheet metals are the most common material for výlisky, especially steel, stainless steel, and aluminum. Copper alloys and certain plastics or composite materials can also be shaped by stamping in specialized processes. Variations include simple stamped blanks, drawn or formed parts, and multi-stage assemblies produced from multiple pieces.

Applications and design considerations

Výlisky are widely used in automotive, electronics enclosures, hardware, appliances, and consumer products due to their suitability for mass production and tight dimensional tolerances. Design considerations emphasize manufacturability in stamping, including appropriate radii, flange sizes, hole placements, and material thickness to balance tool life, material utilization, and part performance.
