Who We Are
A Rapid Prototyping Company in China
GD Prototyping Technology (HK) Ltd, known as GD Prototyping, is a rapid prototyping company with manufacturing resources in Dongguan, China. We support custom parts from design validation to low-volume production, helping engineering and procurement teams balance functional requirements with manufacturing cost.
Process Selection
We evaluate machining, printing, casting, or molding around part geometry and quantity.
Cost-Aware Planning
We weigh setup, tooling, and finishing costs against order quantity and expected design changes.
Project Coordination
Project managers follow production progress and coordinate technical questions through to delivery.

From Prototype to Low-Volume Production
Manufacturing Support as Your Design Develops
As a prototyping and manufacturing partner, we coordinate samples, design feedback, and batch production around your project stage. Materials, quantities, and approval requirements guide each next step.
1. RFQ & Engineering Review
Review CAD files, drawings, quantities, and critical requirements to prepare the quotation and manufacturing approach.
2. Prototype Manufacturing
Machine, print, or cast prototypes using the agreed material and process for your evaluation.
3. Prototype Feedback & Revision
Your team evaluates the prototypes. We review requested changes and confirm the next design revision.
4. Low-Volume Manufacturing
Plan the agreed batch around approved drawings, material requirements, and production quantities.
5. Finishing & Final Inspection
Complete specified surface treatments and verify agreed dimensions and appearance requirements before release.
6. Packaging & Delivery
Protect finished parts, identify package contents, and coordinate shipment to the agreed destination.

Engineering Decisions With Production in Mind
Our approach to rapid prototyping and manufacturing starts with a part’s intended use. We bring material and process decisions into the design conversation, helping your team understand which details affect fit, appearance, and production cost.
Purposeful Precision
Concentrate tolerance control on the dimensions that determine fit and performance.
Open Technical Dialogue
Raise manufacturability questions early and explain their cost or process implications.
Confidential Collaboration
Support NDA arrangements for customer drawings and project information.
Continuous Improvement
Use production feedback to refine methods and address recurring manufacturing issues.
Global Project Support & Delivery
