CORE TECHNOLOGY

From CAD file to shipped part —
end-to-end precision plastic manufacturing.

Shih Gong integrates mold development → injection molding → post-processing under one roof, so customers don't have to coordinate three suppliers. File in, finished part out.

WORKFLOW

How a project moves through Shih Gong

Six standardized stages so you always know where the project sits.

// 01

Requirements

Sales walks through product use case, target volume, budget, and timeline to validate initial feasibility.

// 02

File Review

Engineers inspect 2D/3D files, run moldflow analysis, and flag any structural or molding risks.

// 03

Mold Build

Tooling is built in-house — keeping quality controllable and lead time predictable.

// 04

Trial & Samples

Samples sent for appearance, dimension, and fit verification. Pilot run follows customer sign-off.

// 05

Production & Finishing

Full production runs with optional plating, spray coating, printing, laser engraving, and heat/water transfer.

// 06

Ship & Maintain

QC inspection, ship-out, long-term mold storage. Reorders schedule fast — no re-tooling.

POST-PROCESSING MATRIX

Post-processing capabilities

Injection molding gives you the shape — post-processing is what turns it into a finished product. Below is our in-house and partner-shop coverage.
