What is extrusion?
Digger Specialties :: Frequently Asked QuestionsThere are two common methods of vinyl fence manufacturing: mono-extrusion (single layer) and co-extrusion (two-layer). Some manufacturers maintain and advertise that mono-extrusion is better. Which is better for you? In mono-extrusion, the fence profile (in sizes such as 2" x 6", 5" x 5", etc.) is made out of one layer of material. This process puts ultraviolet inhibitors (which protect the vinyl from sunlight) all the way through the product, even on the inside, where they are not needed.
What is a dual durometer extrusion?
Plastic extrusions, flexible, rigid, dual durometer, high-qu...It is a co-extrusion process that fuses two materials of different physical properties into one uniform or consistent cross section. The most common of these extrusions is the combination of a rigid material, for strength, with a soft or flexible material, for function, into various one-piece profiles. Yes. We co-extrude a variety of shapes and compounds and can extrude PVC (polyvinyl chloride) to PVC, PVC to urethanes, PVC to T.P.E. (thermoplastic elastomer) and polypropylene to T.P.R.
How many suspensions are needed per extrusion?
FAQ - Blade LightingThe number of suspensions needed will depend on the length of extrusions. A recommendation for standard versions are:
What is the difference between extrusion and oven-baking?
Discounted Flint River Ranch: The Precious Paw :: Common FLI...The extrusion process involves steaming the ingredients as quickly as possible, usually less than three (3) minutes, then extruding it under extreme pressure though a metal die. This process expands the food with air creating a uniform shape. Extruding "puffs up" each piece of food, giving it a uniform shape. Some industry professionals believe that extruded foods can cause the condition known as "bloat."
Where can I find a listing of extrusion suppliers?
Aluminum Technology, Aluminum Testing, Aluminum ResearchThe Aluminum Extruders Council provides a searchable online database which allows selection from AEC member companies. Users can limit their search by selecting forms produced, finishing services, fabrication services, special services, soft vs. hard alloy, circle size requirements, and geographic location. While there are certainly standard dies producing angles, channels, bars, tubes, pipes, etc.
What are the tolerance capabilities for the extrusion process?
Aluminum Technology, Aluminum Testing, Aluminum ResearchAluminum extrusions are manufactured routinely to the close dimensional tolerances required for parts that must fit snug with other parts. Cost is minimized when an extruded product is designed to function well at standard production tolerances. However, tighter, custom tolerances can be specified when necessary.
What is the minimum bending radius for an extrusion?
Aluminum Technology, Aluminum Testing, Aluminum ResearchExtruded aluminum tube, pipe and shapes can be formed on conventional bending equipment. The minimum bending radius of a specific extrusion will depend on its size, alloy and temper, the complexity of its shape, and the characteristics of the available equipment. The Aluminum Association publication Forming and Machining Aluminum contains minimum bend radii for several common tube products.
IS IT RECYCLED PLASTIC AND DO YOU USE THE CO-EXTRUSION PROCESS?
Vinyl Decking Fencing FAQs : Delta DistributingThe use of the co-extrusion process is becoming very popular in reducing material expense; The co-extrusion process in and of itself is a proven process and is very successful if used properly. All too often, however, it is used to hide an inferior, sub-standard base material that the manufacturer can purchase at considerable savings. such as post industrial scrap and post consumer scrap. No.
USAVinyl uses co-extrusion technology - why is co-extrusion superior to mono extrusions?
F A Q - Vinyl Fencing - Horse Fence & Privacy Fence - USA Vi...Co-Extrusion technology is the more advanced technology; our product is made in two layers. USAVinyl only uses top quality 100% virgin materials in our extrusions. The outer layer contains a more concentrated amount of UV protection ? 10-12 parts per 100 of TI02/Titanium Dioxide. The inner layer utilizes TRUFORCE - impact modifiers which are the toughest acrylic modifiers in the industry. This is a key reason USAVinyl consistently outperforms the competition in impact testing.
What research and development activities are underway for aluminum extrusion?
Aluminum Technology, Aluminum Testing, Aluminum ResearchActive R&D has been undertaken by private companies, universities, and National Laboratories to advance all aspects of aluminum extrusion technology. A comprehensive collection of past work can be found in the Proceedings from the International Aluminum Extrusion Technology Seminars, known as "ET" for short. These are available from the Aluminum Extruders Council via their Publications list.
back to top 6. Will the macromolecule shear or cleave in a close tolerance extrusion?
FAQsMETHOCEL products are vulnerable to very low pH and very high pH conditions. This may show up as a loss of viscosity over a period of time. Although you got good initial results, there may be a drop in performance that you will observe with time/age. It may or may not matter. Generally, if you are using a non-surface treated METHOCEL product, there are no order of addition considerations.
Can I save production costs by designing with aluminum extrusion?
Caiping-Aluminum Design & ManufactureThe tools required for aluminum extrusion - dies and related elements - are relatively inexpensive compared with those necessary for other production methods. Initial investment may be quickly amortized and even a fairly small production run may pass the "bread even" point, thus economically justifying the use of extrusion.
What advantages is there to using an aluminum extrusion over an aluminum casting?
Caiping-Aluminum Design & ManufactureThe integrity of an extrusion is much more consistent than that of a casting. Castings are inherently more porous due to their manufacturing process, and this results in more material used for structural applications. In result, the aluminum extrusion is inexpensive(dies) and take shorter time than casting manner. ?@
Q - Can the design of my extrusion be changed after the die is cut?
Frequently Asked Questions About Aluminum ExtrusionsA - Possibly - A very minor change is possible, however discussions with engineering will have to be made. If it is possible to make the change a small fee is likely to be charged. More significant changes may potentially require a new die. Again, discussions with Engineering will have to take place to determine the practicality of a requested change. Whatever change is agreed upon, a signed die approval print and purchase order must accompany it to proceed.
Qs.-22Is it possible to do extrusion lamination of polypropylene directly on inks?
SAKATA INX (INDIA) LTDAns. Yes, we have ink on which this process can be applied. For more details please contact any of our branch offices. Ans. Chemically coated films have been found to give the best bond strengths, followed by corona treated films. Ans. Yes, we have the facility in our laboratory to give you this result at varying temperatures, pressures and dwell times. Ans. Normally, this tendency has not been observed with our Lamitop grade of reverse printing inks.
What is the nip load design for your typical extrusion coater/laminator?
Company - FAQTypically 150 pli for flexible packaging and 200 pli for board coating. Please note we have designs for up to 1000 pli for special applications.
Why is oven baking better than Extrusion process used by other pet foods?
Flint River Ranch FAQThis unique baking process changes the hard-to-digest molecules of "raw" starches into easy-to-digest dextrines. This process acts as a "pre-digest" of the kibble food, resulting in less strain on the dog's digestive system and allowing a greater degree of food absorption. A dog's intestinal tract is short; it functions in the most efficient manner when the food is concentrated and can be quickly digested. Furthermore, Extruded products may cause Bloating in dogs.
