Extrusion design Inquiry (采购产品): Extrusion design Thursday, March 09, 2006 To whom it may concern, My name is Robert Pratl, I am a Special Effects Designer with a Las Vegas / Toronto based company named Pyrotek Special Effects Inc. We are continuously looking for methods to create new and innovative ideas in special effects. Our customized designs and broad range of special effects allows us the opportunity to be one of the leading trend setters in the industry. We focus on the concert touring industry as well as custom and permanent installations. We are more of an end user when it comes to the quantity of material that we use in our manufacturing but it is variable from project to project. One of our specialties is producing Indoor Water Projection Screens and Rain Curtains. I have a custom circular water screen project that requires me to change the way I normally have my manifolds manufactured. In this new revision I have changed the main structure and am looking for a new company to provide me with the material as well as fabrication, finishing and some assembly. I have always used aluminum for the main structure and have considered other materials both past and present. In my opinion aluminum is still the best choice for many reasons. This project requires us to actually curve the main structure as well as the water distribution manifold that is attached to it. The new design has prompted me to revise my standard linier screen design at the same time. The main chassis has been streamlined in the new design. This new shape reduces the volume of water in the system when in operation and allows it to drain quicker. In selecting a material to suit this purpose, I would also like to be able to use it in my other linier Water Screen applications as well. I am hoping that the bending process is a final step and can be skipped to have both options. This will allow me to use most of the same final assembly components in both applications. This project requires 91 lineal feet of the curved structure assembled. There will be an additional 20 to 30’ “possibly more” of unassembled spare curved material for possible future back up replacement. Following the production of the curved batch, but using the same set up, we would also like to produce a run of straight stock for future use. The quantity of the straight run will be determined by your manufacturing cost factors. I am not sure if you require a minimum run when you manufacture your extrusion. Also will it be monetarily better for us to increase our material order to offset the setup costs. We will most likely not consume a large volume of structural material annually. You will have to let me know what my options are in this regard. I have designed 2 structures that are the same in shape, but are produced by 2 different manufacturing processes. They are as follows: ? Shape 1 is a 2 piece rolled or pressed spilt chassis that would connect together to create 1 main structural cavity. In the reflected drawings there is no representation of the joining process. ? Shape 2 is a custom 1 piece solid or hollow extrusion that would be based on your recommendations for the manufacture as well as the structurally properties required in the curving process. I am very open to any input that you might have in the design. I am also willing to use an existing extrusion shape that you already have a die for. The overall volume in the shape is very important as well as the distribution of that volume. As long as it comes close I would be willing to look at it. I have provided mechanical drawings with material, surface, and finish specifications. Attached is a zip file containing 10 drawings in PDF format. If you print the PDF files print them at full size 24x36. Please contact me with any problems opening the attached file, or with any question or suggestions that you might have. I am under some very tough time constraints for this project. I would like you to quote both options for me. As I mentioned I will also be looking for fabrication, assembly, and finishing services. The first step is securing the material. I am looking forward to your reply. Sincerely, Robert Pratl Robert L. Pratl ? Pyrotek Special Effects / Laser Design Productions ? Office 702-450-7976 ?
