How the Factory Works
Production Starts With Clear Requirements
Our review starts with the drawing package: geometry, material, quantity, critical features, surface finish and required documents.
We identify open technical points before process release, then use the approved project information to plan machining, inspection and delivery preparation.

Production Environment
Inside the Factory
Follow the order through the production floor, machining operations, dimensional inspection and protective packing.
Production Control
Control the Details That Affect the Part
The approved drawing, specification and acceptance criteria provide the reference for production decisions throughout the order.
Engineering Review
Missing dimensions, conflicting notes and other technical questions are raised before process release.
Production Coordination
Material status, machining sequence, inspection points and delivery needs are coordinated against the order.
Critical Requirements
Critical dimensions and functional interfaces are identified for both machining and inspection.
Change Confirmation
Revisions affecting material, geometry, finish or acceptance are confirmed before related work continues.
Quality in the Workflow
Plan Inspection Before Production
Define critical dimensions, sampling requirements, inspection records and approval points before machining starts. Clear acceptance criteria support both process planning and final release.
Project Fit
Send the Information Needed for Review
Send a complete RFQ package so engineering can assess manufacturability, identify open questions and prepare the process and inspection plan.

What does engineering review before production?
We review the current drawing package, material, quantity, critical features, finish and documentation requirements.
How is the manufacturing route selected?
The proposed route is based on part geometry, material, tolerances, quantity and finish requirements.
How are inspection requirements handled?
Critical dimensions, acceptance criteria and reporting needs are incorporated into the inspection plan.
How do I request a factory visit or supplier audit?
Send the proposed scope, participants and preferred timing to our team for review.
