Our 10-Step Operational Workflow

Precision Manufacturing & Quality Control Execution

01

NDA & Drawing Review

We sign legally binding NDAs to protect your proprietary designs. Our senior engineers perform deep feasibility assessments of your 2D/3D drawings.

 
 
02

Accurate Quotation

Transparent and comprehensive cost structures based on raw materials, tolerances, and finishes. Flexible options provided with a fast 24-hour turnaround.

 
 
03

DFM & Moldflow Optimization

Comprehensive Design for Manufacturability (DFM) reporting and computer-aided moldflow simulation to proactively eliminate potential defect risks before tooling.

 
 
04

Mold Design & Precision Tooling

Parametric 3D mold layout and precise metal block cutting using advanced CNC machinery, mirror EDM sparkers, and wire-cutting to lock in micron-level tolerances.

 
 
05

Mold Trial & FAI Testing

Initial machine runs to optimize cycle pressures and temperatures. Full-dimensional inspection reports generated via CMM validation for your clearance.

06

Golden Sample Sign-off

Sending approved boundary and aesthetic samples directly to you. Signed-off Golden Samples establish the definitive standard for consistent mass production.

 
 
07

Pre-production Trial Run

Executing pilot low-volume runs to test tooling endurance, check stabilization controls, and fine-tune operational cycle packages before mass scaling.

 
 
08

Mass Production & In-process QC

Full automated line deployment. Strict process oversight including machine operator checks, random interval tests, and rigorous IPQC monitoring.

 
 
09

Final Inspection & Custom Packaging

AQL-standard outgoing batch inspections. We formulate customized protective packaging (blisters, anti-static boxes, pallets) to safeguard your freight.

 
 
10

Secured Global Logistics

Reliable freight forwarding covering Air, Sea, and Express lanes. Seamless door-to-door delivery setups (DDP/DDU) with export clearance and full logistics tracking.
