Bill of Materials (BOM) Analysis Jobs

I’m advancing an existing product concept into a fully detailed prototype and need clear, professional material specifications to guide the next build phase. Here’s what I’m after: • A detailed product design prototype that captures the form, fit, and function of the concept. • A concise bill-of-materials outlining recommended materials, grades, finishes, and any sourcing notes. • Explanations for each material choice—why it suits the design goals, durability, manufacturability, and cost considerations. The core focus is the material specification, but if you also have the capability to add 3D modeling or functional schematics, let me know; I’m open to folding those extras into the workflow for a smoother hand-off to manufacturing. ...

I am building a new converting line and need a purpose-built, metal automatic paper take-off unit. Core dimensions are fixed: the expanding air shaft must be Ø74 mm and the web width 2 000 mm. Drive will come from an AC gear motor, so please size and specify a model that delivers smooth, adjustable unwind speed without introducing vibration. Stable web tension is critical, therefore I want a dancer-type tension rod fitted with a sensor and closed-loop, fully automatic control. All control hardware, wiring diagrams, and PLC/HMI logic (if required) should be part of the package so the unit can slot straight into the rest of my line. Directly after the take-off section I need an IR dryer with an integrated fan. It has to mount on the same frame, clear the 2 000 mm web, and deliver ev...

I am ready to prepare a full primary-engineering design package for your AIS, GIS, Wind-farm or FACTS substation, taking the project from concept through to construction-ready drawings and a quantified Bill of Quantity. My scope covers every critical drawing and calculation normally required by utilities, EPCs and independent power producers. You will receive the following discrete deliverables, each issued in native AutoCAD (DWG) and PDF, with supporting calculation sheets in Excel or ETAP as appropriate: • Single Line Diagram (SLD) if needed • Protection & metering SLD if needed • General layout plan and sections • DSLP and detailed equipment layouts • Earthing / grounding layout with step-touch voltage report • Cable trench layout and schedul...
