Animated text extrusion
Extrusion is a simple compressive metal forming process. In this process, piston or plunger is used to apply compressive force at work piece.
These process can be summarized as follow. In this type of extrusion process, metal is forced to flow in the direction of feed of punch.
The punch moves toward die during extrusion.
This process required higher force due to higher friction between billet and container. In this process, metal is flow toward opposite direction of plunger movement. The die is fitted at opposite side of punch movement. In this process, the metal is allowed to flow through annular space between punch and container. Your email address will not be published.

This process is extensively used in pipes and steel rods manufacturing. The force used to extrude the work piece is compressive in nature. This process is similar to drawing process except drawing process uses tensile stress to extend the metal work piece. The compressive force allows large deformation compare to drawing in single pass.
The most common material extruded are plastic and aluminum. Extrusion process can be classified into following types. This process uses fluid to apply pressure on billet. In this process, the friction is eliminated because the billet is neither contact with cylinder wall or plunger.
There is a fluid between the billet and plunger. The plunger applies force on fluid which further applied on billet. Normally vegetable oils are used as fluid. This process accomplished by leakage problem and uncontrolled speed of extrusion. If the extrusion process takes place below crystallization temperature or room temperature, the process is known as cold extrusion.

Title: Extrusion 1 Extrusion A typical extruder. Extrusion is the method that produces the largest volume of plastic products Extruded products are generally long uniform and solid or hollow complex cross-sections 2 Sheet and Film Extrusion Other types Tubing, Electrical wire coating, Pipes To extrude thin film, air is forced into an extruded sheet and then either pinched or cut. A common dye to produce sheets is referred to as the coathanger dye. The part is cooled within the mold.
Once cooled, the part is eased out of the mold with ejector pins 5 Molds Cold runner, Two-plate mold Cold runner, Three-plate mold Hot runner mold 6 Machine Cost range 85, -Die cost 20, -Mold cost approx. Air is then pushed is and the part is made. The mold is removed and excess pieces are removed as well.
Air is blown in and the part is made. The blow pin is then removed. Parts cannot include holes and openings.
Material thermoplastics, must exhibit high, uniform elongation Packaging trays, signs, appliance housings, refrigerator liners, shower stalls 10 No Transcript 11 Beads, blowing agent, and heat Pre-expanded beads may be shaped just as plastics Structural foam molding created hard outer shell and light cellular core, outside is cooled rapidly Polyurethane foam processing utilizes chemical reactions to create foam which is poured into molds or sprayed on surfaces for insulation.
Thermosets are used because of their ductility at room temperature. Advantages strength, toughness, improved dimensional accuracy, and faster cycle times Solid phase forming is carried out at temperatures C. Below the melting point.Extrusion tools duplicate vertices, while keeping the new geometry connected with the original vertices. Vertices are turned into edges and edges will form faces.
Single vertex extruded. Single edge extruded. This tool is of paramount importance for creating new geometry. It allows you to create parallelepipeds from rectangles and cylinders from circles, as well as easily creating such things as tree limbs.
The axis on which vertices and edges are extruded along can be set interactively. Faces are extruded by default along their averaged normal.
The extrusion can be limited to a single axis by specifying an axis; see Axis Locking. Only the border loop gets extruded. The inner region of the selection gets moved unchanged with the extrusion.
Selected face. During extrude. Set to Z axis. Although the process is quite intuitive, the principles behind Extrude are fairly elaborate as discussed below:.
First, the algorithm determines the outside edge loop of the extrude; that is, which among the selected edges will be changed into faces. By default see belowthe algorithm considers edges belonging to two or more selected faces as internal, and hence not part of the loop. If the edges in the edge loop belong to only one face in the complete mesh, then all of the selected faces are duplicated and linked to the newly created faces.
For example, rectangles will result in parallelepipeds during this stage. In other cases, the selected faces are linked to the newly created faces but not duplicated.The Extrusion Process.
Additives, such as colorants and UV inhibitors, in either liquid or pellet form are often used and can be introduced into the resin below arriving at the hopper. The process has much in common with plastics injection molding though differs in that the process is usually continual. While injection molding can offer many similar profiles in continuous lengths, usually with added reinforcing, the finished product is pulled out of a die instead of extruding the fluid resin through a die.
As the material enters the feed throat near the rear of the barrel it comes in contact with the screw. The rotating screw forces the plastic resin forward into the barrel that is heated to the desired melt temperature depending on the resin. This allows the plastic resin to melt gradually as it is pushed through the barrel and lowers the risk of overheating which may cause degradation in the polymer.
At the front of the barrel, the resin leaves the screw and travels through a reinforced screen to remove any contaminants. After passing through the breaker plate resin enters the die. The die is what gives the final product its profile or shape and must be designed so that the molten plastic evenly flows from a cylindrical profile, to the product's profile shape.
Uneven flow at this stage would produce a product with unwanted stresses at certain points in the profile. These stresses can cause warping upon cooling. Almost any shape imaginable can be created so long as it is a continuous profile. The product must now be cooled which is usually achieved by pulling the extrudate through a water bath.
Plastics are excellent thermal insulators and are therefore very difficult to cool quickly. Compared with steel, plastic conducts its heat away times more slowly.
In a tube or pipe extrusion line, a sealed water bath utilizes a carefully controlled vacuum to keep the newly formed and still molten tube or pipe from collapsing. A set of cooling rollers is generally used in the sheet extrusion process to cool sheet as it exits the extruder.
Sometimes, on the same line, a secondary process may occur before the product has finished its run. Once the product has cooled, it can be spooled, or cut into lengths for later use.In this tutorial, DomQuichotte shows you how to use a preset from the Layered Extrusion bundle to easily vibrate parts of the extrusion and save it as an animated GIF. Create a document with x pixels.
The larger the picture, the harder it will be to generate a file size suitable for the web. But you can also reduce the image size during export later. Choose the yellow color ffba The layer mask of the layer is not needed, so you can delete it if you want. I choose the Akzidenz Grotesk Bq Super Regular font in capitals with a font size of pt and a line spacing of pt. Of course you can choose another font. The text color is unimportant as we will change it later via the panel.
Under Basics, set the elements to 5. Select color as area and define a new color with ff3e3e. Also activate the contour with automatic stroke, inner position and black color.
In addition, the outline should be disabled. Make sure the text layer is selected and click Create. Open the Advanced Extrusion folder in the layers panel. Repeat this with the other two layers. Hide layers Vibe 1 — 3 and show Vibe 0. Do do that, click on the time directly below the frame. Add a new frame and hide Vibe 0 and show Vibe 1. Repeat this two more times with Vibe 2 and Vibe 3 displayed at a time.
Reduce the image size to x pixels and click Save. Your animated GIF is ready now. This tutorial is really easy to use. If you are familiar with photoshop you can do it in under 5 minuits otherwise it will take a little longer like me but i did it in 15 minuit,s step by step.
A great help is the FX Panel! The panel and the pack are great timesavers and makes things like obove very much easier. LOve it. You must be logged in to post a comment. By DomQuichotte. In Tutorial.
