A mandrel is an auxiliary device for the formation of cavities and is utilized in metal forming for indentation or forcing-through procedures. There is a differentiation between hollows and solid mandrels. For seamless tube production, mandrels are utilized for bar extrusion as well as for mandrel drawing as auxiliary devices, whereat the mandrel always determines the inner diameter of the deformed tube.
usually a steel, aluminum or other alloy shape (extruded or machined) that will form the internal shape of a dip molded part. Multiple mandrels are normally mounted to a bar. The bar is then placed into a master rack or mounted directly on the arm of the machine.
The threaded member of the installation tool that engages the threads of the insert and applies the installation load. Spin-spin tools typically use a standard socket head cap screw as a mandrel. Most spin-pull tools use a more complex mandrel, but some newer tools use a standard socket head cap screw. To install an insert with external threads, the mandrel has internal threads.
This word is mostly used for holding device which grips the workpiece internally - such as the special mandrels for pen making. In the old days the mandrel was the lathe spindle - the rotating shaft in the headstock.
A faceplate fitted with "dogs" or clips to hold the work during turning, fitted to the lathe. or as a seperate self contained tool. In engineering, a mandrel is a bar set between centers to mount tools or work.
1. A tapered axle inserted into a hole in a piece of work to support it during machining. 2. A metal bar used as a core around which material may be cast, molded, forged, bent, or otherwise formed. 3. The shaft and bearings on which a tool is mounted, as in a drill or circular saw.
A mandrel (pronounced , and also spelled mandril; in American English also called an arbor) is either an object used to shape machined work; a tool component that grips or clamps materials to be machined; or a tool component that can be used to grip other moving tool components.
The core around which the paper or web stock is wound. Also refers to a cylinder substrate to which a label or tape is applied to determine its ability to maintain adhesion on a curved surface. The ability is dependent on the adhesive properties and the stiffness of the face stock (thickness).
The fixed or floating projection positioned in the die opening that forces metal to flow around it. The wall thickness of the extrusion is determined by the difference in the dimensions of the die aperture and the mandrel.
(1) The core that paper, fabric or film is wound around to form pipes or tubes. (2) In extrusion, the central post for forming the interior of pipes or tubing. (3) In decorating, the post used to hold the interior of the part to be decorated.
a metal component of a mold which has rubber formed and vulcanized all around it, without bonding, so it can be removed from the final part to leave an aperture or passage; also the core of a die around which rubber is extruded to form a center hole
A cylinder looking unit that is used with coil binding machines with a coil inserter. The coil winds around the mandrel before being inserted into the punched document. The size of the mandrel depends on the size of coil being used.
(1) A form used as a cathode in electroforming; a mould or matrix. (2) Support used in bending tests. Matt finish (Matt finish) : A uniform finish of a fine texture virtually lacking specular reflectivity.
