When polymer exits the die of the extruder it will swell,
this action is referred to as die swell.
Thanks me later :P
Type your answer here... Extrusion is the open die punching process whether forging is close die punching process.
Extrusion is a manufacturing process where material is pushed through a die to create a specific shape or profile.
Stamping involves a force applied to a die that removes a section of material, typically thin. Extrusion is a process where a force is applied to a fluid material which is pushed through a die creating the rough final form. Extrusion is much less wasteful in most circumstances.
One example of an extrusion is the process of creating metal rails or bars by forcing raw metal through a shaped die to produce a continuous profile.
Indirect extrusion is a manufacturing process where a material, typically metal, is pushed through a die to create a desired shape. Unlike direct extrusion, where the material flows in the same direction as the applied force, in indirect extrusion, the material is contained within a chamber and the die is pushed into the material, causing it to flow in the opposite direction. This method can result in improved surface finish and dimensional accuracy, while also reducing the energy required for the process. Indirect extrusion is often used for producing complex profiles and shapes in various industries.
That is the correct spelling of "extrusion" (forming by pressing through a die or opening).
The formula for blow-up ratio (BUR) is BUR = (D1/D2) where D1 is the diameter of the extruder screw and D2 is the diameter of the die in the blown film extrusion process. The blow-up ratio determines the amount of expansion that occurs in the film extrusion process.
n.) The act or process of pushing or thrusting out. (n.) The act or process of shaping by forcing through a die. (n.)An object or material produced by extruding
1::drawing is pull type process where specimen of desired dia is simply pulled out through die opening...'where in extrusion it is push type process ...2::draing max. force applied is limited according to yield strenth of metal to be drawn....
The extrusion process in technology involves forcing a material, often plastic or metal, through a shaped die to create a continuous profile with a specific cross-section. This method is commonly used in manufacturing components such as pipes, sheets, and rods. The material is heated to a malleable state before being pushed through the die using a screw or hydraulic mechanism. Extrusion allows for efficient production of complex shapes and can be easily scaled for high-volume production.
Extrusion fiber refers to a type of synthetic or natural fiber produced through the extrusion process, where a polymer or material is melted and forced through a die to create continuous strands. This method is commonly used in the production of fibers such as nylon, polyester, and polypropylene, which can then be spun into yarns or used in various applications like textiles, composites, and filtration. The extrusion process allows for precise control over the fiber's diameter, structure, and properties, making it a versatile manufacturing technique.
An extruded product takes the shape of the exit nozzle or die whereas a calendaring process thins out the blob of material by passing it through a series of rollers which squeeze and flatten the material. sticky tape and cling film is made by calendaring but hose pipe is made by extrusion.
