Process Capabilities

Jingxin Precision is equipped with metrology-grade structured-light scanners, laser 3D scanners and portable scanning systems, supporting measurement for small precision components up to large-size assemblies. Professional reverse-engineering software is used for point-cloud cleanup, mesh repairing, NURBS surface fitting and parametric solid reconstruction. Complete deliverables include STL mesh, STEP / IGES solid models and dimensioned 2D engineering drawings.

Basic Reverse Engineering Processes

Extended / Precision Processes

Part Pre-Preparation: Surface cleaning, anti-reflective treatment for shiny or transparent workpieces.

3D Data Acquisition: Structured-light scanning or laser scanning to capture high-density point-cloud data of physical parts.

Point-cloud & Mesh Processing: Multi-scan alignment, noise removal, hole filling and watertight mesh generation.

CAD Reconstruction: Feature recognition, analytic surface fitting and free-form NURBS surface reconstruction to output parametric solid CAD models.

2D Engineering Drawing Generation: Dimension annotation, GD&T definition and drawing output for downstream machining.

Deviation Inspection: Compare reconstructed CAD model against original scan data, generate color-coded deviation report.

Extended Service: Directly connect to CNC, 3D printing, vacuum casting or injection-molding for sample validation and mass production.

Applicable Project Stages

Reverse engineering supports multiple phases of product development and equipment maintenance

Proof of Concept

Digitize existing physical models to generate baseline CAD data for new-product concept redesign.

Functional Validation

Reconstruct CAD files of legacy or discontinued components, produce physical samples for functional and performance verification.

Assembly Validation

Digitize multi-part assemblies, verify fit clearance and assembly interference in virtual digital environment.

Appearance Samples

Replicate complex free-form appearance surfaces, support subsequent appearance sample manufacturing for exhibition and marketing.

Small-Batch Pilot Production

Deliver production-ready CAD data for small-batch reproduction of spare parts without original drawing documents.

Bridging Mass Production

Provide complete digital data package for formal mold development and mass-production preparation.

Input & Output Data Capabilities

Acceptable Input Sources

Physical workpieces, existing mesh files (STL / OBJ), point-cloud data.

Deliverable Output Formats

Mesh format: STL, OBJ for 3D-printing simulation

3D solid: STEP, IGES, XT, native SolidWorks / UG / CATIA parametric files

2D output: PDF / DWG engineering drawings with dimensions and GD&T annotations

Tolerances and Surface Quality

Scanning & Reconstruction Tolerances

Standard reconstruction tolerance: ±0.05 ~ ±0.10 mm

High-precision reconstruction tolerance: ±0.02 ~ ±0.05 mm for small precision parts Note: Final accuracy is subject to workpiece surface condition, wear status and feature complexity.

Angular Tolerance

±0.3° for reconstructed CAD features.

Surface Reconstruction Quality

Regular geometric features (plane, cylinder, hole): high-accuracy analytic surface reconstruction.

Complex free-form surfaces: G2 continuous NURBS smooth surfaces.

Deviation inspection report available to show gap between CAD model and original scanned data.

Post-treatment & Data Optimization Services

Full-range data post-processing to achieve manufacturing-oriented CAD models

Mesh Repair

Hole filling, noise cleaning and non-manifold geometry correction.

CAD Optimization

Wall-thickness checking, fillet adjustment, draft-angle adding for moldability.

GD&T Annotation

Assembly Data Processing

Positioning constraint and interference checking for multi-component assemblies.

Deviation Analysis

Color-map comparison report between reconstructed CAD and raw scan data.

Process Selection Guide

When to Choose Reverse Engineering?

Choose Reverse Engineering when you need:

Digitize physical parts without original CAD drawings or legacy discontinued spare-part reproduction.

Reconstruct editable parametric CAD files from existing samples for redesign or modification.

Capture complex free-form surfaces for appearance copying, digital archiving or assembly simulation.

Obtain complete data package for follow-up prototype making or formal mold development.

Consider CNC Machining when your parts:

You already have complete CAD files and need high-precision solid-block functional parts.

Consider 3D Printing when your parts:

Only require mesh copies for visual prototypes, no need for editable parametric CAD.

Consider Vacuum Casting when your parts:

Need 10-50 cosmetic copies directly from master physical samples.

Consider Injection Molding when you need:

Design is finalized, mass-volume plastic-part production over 1000 units.

Reverse Engineering Guidelines

To improve reconstruction quality and reduce downstream manufacturing risk:

Workpiece Condition: Minimize surface wear, deformation and damage of physical samples; heavily worn parts will reduce reconstruction accuracy.

Occluded Features: Deep hidden cavities and fully enclosed internal structures cannot be captured by optical scanning; CT scanning solution is required for internal geometry.

Feature Classification: Distinguish functional features, assembly features and worn artifacts on original sample during CAD reconstruction.

File Purpose: Clarify your end-use requirement (3D printing / CNC / mold design) so engineers can optimize model accordingly.

Assembly Project: Mark datum reference for multi-component assemblies to ensure correct relative position of each part.

Delivery Time and Logistics Services

Standard Delivery Time

Simple single-part reconstruction: 2-4 business days; complex free-form or multi-part assembly: 4-8 business days.

Expedited Service

Fast-track project available subject to part complexity and workload. Physical-part mailing is required for most scanning projects.

Logistics for Physical Samples

Support customer shipping physical samples to our facility; we can return original samples after project completion via DHL, UPS, FedEx.

Packaging Standards

Quality Assurance and Testing System

Quality control runs through full reverse-engineering workflow

Pre-Project Evaluation

Analyze sample condition, define reconstruction tolerance and deliverable scope before work starts.

Scanning Quality Check

Verify point-cloud completeness, ensure no missing key surface features.

CAD Reconstruction Inspection

Check feature dimension, surface continuity and manufacturability of output CAD model.

Deviation Comparison

Overlap reconstructed model with raw scan data to generate deviation color-map report.

Output File Verification

Check file integrity, format compatibility and drawing annotation correctness before delivery.

Free DFM Feedback

Provide manufacturability suggestions for downstream manufacturing at quotation phase.
