I need a complete, ready-to-manufacture steel cylinder and piston assembly designed, documented, and packaged for straightforward production. The core deliverables are the 3D CAD models, fully dimensioned 2D drawings, and a concise bill of materials that calls out grade, heat treatment, and surface-finish requirements suited to high-pressure, high-temperature duty. I will validate the work by opening the STEP files, reviewing the tolerance stack in the drawings, and running interference checks, so please keep assemblies clean, fully constrained, and free of suppressed parts. Any finite-element stress or thermal simulations that support material and wall-thickness choices are a welcome plus. To speed procurement, include machining notes (bore finish, honing pattern, recommended hard-chrome or nitriding process if you use either) and a short quality-control checklist I can hand straight to the shop floor. Deliver all files in native CAD format as well as STEP/IGES and PDF for downstream teams. The project is considered complete when: • All models and drawings open error-free. • Critical dimensions and tolerances are annotated. • Material and treatment specs are documented. • A brief assembly guide confirms piston-to-cylinder clearance and ring placement. If you have experience with tight-seal or high-compression piston assemblies, let me know in your proposal and feel free to attach a sample drawing set.

At high pressure and temperature, a piston-to-cylinder clearance that looks correct in CAD can still fail once thermal expansion, surface finish, ring stack and tolerance accumulation are considered. I would therefore define those limits before freezing the geometry rather than treating this as a simple modelling job. I would start from your working and peak pressure, temperature, fluid, bore, stroke, duty cycle and sealing requirements, then establish the initial wall thickness, piston clearance and critical fits. The assembly would then be built as a clean, fully constrained SolidWorks model and checked for interference at both nominal and tolerance-limit conditions. The manufacturing package would include native CAD, STEP, IGES and PDF drawings, critical dimensions and tolerances, material grades, heat-treatment and surface-finish requirements, BOM, piston and ring arrangement, machining notes for the bore and honing, and hard-chrome or nitriding only where technically justified. I would also include a concise shop-floor QC checklist and assembly guide so the manufacturing team has clear inspection criteria rather than having to interpret the CAD themselves. My background combines 7+ years of freelance engineering work, extensive mechanical design experience and active SolidWorks use. The focus here would be manufacturability and dimensional control, not simply delivering geometry that opens without errors. If stress and thermal validation are required, I would first freeze the operating envelope and baseline geometry so the simulation is based on the actual pressure, temperature and material conditions rather than assumptions. Before I begin, please send the target bore and stroke together with the maximum pressure, maximum temperature, working fluid and expected operating cycle. Those values determine the clearance, material and surface-treatment decisions. Best regards Mahmoudreza
