I need a precise technical drawing for an extension spring that will be fitted into industrial-machinery assemblies. The spring must reliably handle a medium load while being manufactured from spring steel grade 2. The drawing has to show every critical dimension—wire diameter, outside diameter, free length, coil count, hook style, and any tolerances—so a tooling shop can proceed straight to production without additional clarification. A simple 2D CAD sheet is fine, but if creating a 3D model speeds up your process or improves clarity, feel free to include it as well (STEP or IGES preferred). Handing over the native CAD file plus a PDF print is all that’s required. Once I confirm the dimensions and notes match the specifications, the job is done and paid in full.

can create a complete production-ready technical drawing package for this extension spring, including all manufacturing-critical dimensions, tolerances, and spring specifications required for direct tooling and fabrication. From the provided photos and load-test sheet, I can already identify the main parameters: Spring type: Extension Spring Material: Spring Steel Grade 2 Wire diameter: 4.80 mm Outside diameter: 26 ±0.5 mm Body length: 155 mm Free length: 182 mm Hook type: Machine-formed center hooks Coating: CED + Powder Coating Conical spring profile noted in the document Load test values: 50 mm extension → 132 kg 60 mm extension → 159 kg I will deliver: Detailed 2D manufacturing drawing (PDF + DWG/DXF) Native CAD files 3D spring model STEP/IGES export for manufacturing compatibility Full dimensional callouts: coil count pitch hook geometry end orientation tolerances material notes finish/coating notes load specifications I have experience preparing fabrication-ready mechanical and sheet-metal CAD files for production environments, so the final package will be organized specifically for workshop/manufacturing use without requiring additional clarification. If needed, I can also include: spring rate calculation estimated preload section views enlarged hook-detail views manufacturing notes for CNC spring forming I can start immediately and deliver the complete drawing package quickly once dimensions are confirmed.

Hi there, I am a Mechanical Engineering student and I can deliver a precise manufacturing drawing (DWG/PDF) and a 3D CAD model (STEP/IGES) for your extension spring within a few hours. However, 'medium load' is not a manufacturing specification. To proceed immediately, please confirm if you already have the exact dimensions (wire diameter, OD, free length) or if you need me to calculate them based on a specific target force (in Newtons) and extension length. Looking forward to working with you!
