Cone Calculator is a professional engineering and fabrication tool for developing accurate flat pattern layouts for different types of cones and conical components. Designed for fabrication engineers, fitters, mechanical engineers, workshop professionals, and industrial manufacturers, the app simplifies complex cone development calculations and provides practical dimensions for plate marking, cutting, and fabrication. It is useful for pressure vessel fabrication, process equipment, piping, heat exchangers, storage tanks, ducting, and general sheet metal fabrication. Supported Cone Layouts • Full Cone Development • Half Cone Development • Truncated Cone Development • Multi-Level Truncated Cone • Eccentric Cone Development • Multi-Level Eccentric Cone • Tori Cone / Knuckle Cone • Tori Cone with Knuckle at Large End • Tori Cone with Knuckles at Both Ends Full, Half & Truncated Cone Generate flat pattern developments for concentric conical shapes. Calculate the required development dimensions, radius, angles, and cord lengths for plate layout and fabrication. Multi-Level Truncated Cone Develop large truncated cones in multiple sections when the complete cone cannot be manufactured from a single plate or when available sheet or plate size is limited. This provides practical development information for fabrication and assembly of large conical components. Eccentric Cone Generate flat pattern layouts for eccentric cone transitions using the supported development method. The calculator provides development information and marking dimensions for the top and bottom profiles, making it useful for offset and eccentric fabrication applications. Multi-Level Eccentric Cone Develop large eccentric cones in multiple sections for applications where a single-piece development is impractical because of component size, plate dimensions, or fabrication requirements. Tori / Knuckle Cone Calculate flat pattern development for conical components incorporating knuckle geometry. Supported configurations include: • Knuckle at Large End • Knuckle at Both Ends • Straight Face Dimensions Features • Accurate cone flat pattern development • Full cone layout • Half cone layout • Truncated cone development • Multi-level cone development • Eccentric cone development • Multi-level eccentric cone development • Tori / knuckle cone development • Development radius calculation • Development angles • Cord length calculations • Fabrication-ready marking dimensions • Metric and Imperial unit support • Automatic unit conversion • Simple and professional interface • Fast calculations • No internet connection required • No distracting advertisements Applications Cone Calculator is useful for: • Pressure Vessel Fabrication • Process Equipment Fabrication • Heat Exchanger Manufacturing • Storage Tank Fabrication • Piping Fabrication • Sheet Metal Fabrication • Ducting and Transition Fabrication • Industrial Equipment Manufacturing • General Fabrication • Workshop Layout and Marking Designed For • Fabrication Engineers • Mechanical Engineers • Design Engineers • Production Engineers • Fabrication Fitters • Workshop Supervisors • Fabrication Contractors • Piping Professionals • Process Equipment Manufacturers • Engineering Students Cone Calculator helps reduce manual geometry calculations, save fabrication time, minimize layout errors, and improve accuracy when transferring developed dimensions onto plate or sheet metal. Whether you are developing a simple full cone, truncated cone, eccentric cone, large multi-level cone, or knuckle cone, Cone Calculator provides a convenient engineering tool for practical fabrication and layout development. For fabrication-ready results, using appropriate mean dimensions during layout development is recommended where applicable.

Screw Flight Calculator will give you handy Calculation of Screw Flight development. It will give you Flat pattern Size for Cutting Blank plate for development or fabrication of Screw flight. This app is very useful for those who are working in the field of Screw Conveyor or Ribbon Blender fabrication. In this App Input is Required Outside & Inside Diameter of Screw, pitch of flight, material thickness & specific gravity of material of Construction such as carbon steel, Stainless steel,Copper, Brass or Bronze material. This app Gives Output as Development Outside Diameter of raw Plate Circle & Inside Diameter of Circle so that it will be perfectly fit with shaft or pipe on which it will be going to weld after twisting of raw plate. It app includes addition Element of Radial Cut Required for flight development, but it is advisable to use full circle for Cutting. This app is also for those who are working in the field of fabrication of Pressure vessel, Heat ex-changer, Storage Tank, Agitator & Mixer and any other process equipment. this app also calculate the weight of material after cutting according to development.
