How We Work With You

From initial concept to mass production, Yeh Sheng provides comprehensive engineering support. Our transparent workflow ensures your project is delivered on time, on budget, and to your exact specifications.

01

Inquiry & Requirement Analysis

The process begins when you send us your project details. To provide an accurate quotation and feasibility assessment, please provide:

Drawings: 2D (PDF) with tolerances and 3D (STEP/IGES) files.
Material Specifications: Required hardness, density, or specific alloy standards (e.g., MPIF, JIS).
Quantity: Estimated annual usage (EAU) or batch size.
02

Engineering Evaluation & DFM

Our engineering team reviews your design for Design for Manufacturability (DFM). We may suggest minor design modifications to optimize the part for the powder metallurgy process, helping you reduce tooling costs and improve part strength.

03

Quotation & Tooling Development

Once the design is finalized, we provide a formal quotation including tooling costs and unit prices. Upon approval, we proceed with mold design and fabrication. Our in-house tooling capabilities ensure precision and faster lead times.

04

Prototyping & Sample Approval

We produce T1 samples for your verification. We provide a full dimensional inspection report with the samples. Mass production begins only after you have approved the samples.

05

Mass Production & Quality Control

Our ISO 9001 certified production line handles compacting, sintering, sizing, and any necessary secondary operations (machining, heat treatment, plating). Rigorous QC checks are performed at every stage.
