Product Finish

Where Japanese engineering standards meet Vietnamese manufacturing agility

Surface Quality

Product Finish

A smooth surface ensuring high-quality finish free of defects

What is Polishing?

Mold Surface Refinement

Polishing smooths mold surfaces by removing roughness, scratches, and unwanted particles using specialized tools

High-Quality Finish Assurance

Ensures a smooth, glossy surface for defect-free molded products with consistent finish quality

Purpose of Precision Polishing for High-Performance Molds

High-precision CNC machining supported by a robust quality control system ensures consistent accuracy and reliable performance

Improves Product Quality

Eliminates scratches, surface pitting, ensures smooth glossy finish meeting technical requirements

Minimizes Aluminum Sticking

Reduces risk of aluminum sticking to mold, inconsistent products, and non-uniform surfaces

Increases Production Efficiency

Smooth surface allows material to flow evenly, shortening cooling times and accelerating speed

Extends Mold Lifespan

Protects mold surface, minimizes frictional forces and high temperatures impact

FINISHING TYPES

Leading Surface Finishing

Dynamo Vietnam delivers uncompromising quality with 03 finishing options that combine Mitutoyo SJ-310 metrology under a comprehensive manufacturing ecosystem, guaranteeing superior surface accuracy and reaching customers

Three Types of Surface Finishes

Three precision-engineered finishing types delivering smoothness, durability, and consistent mold performance—validated by high-accuracy surface inspection before delivery.

Fine Polish (Mirror)

鏡面

Mirror-like shiny surface that helps molds operate smoothly and eliminates frictional wear issues

Draw Polish

磨き立て目

Polishing along the pin direction (parallel to drawing direction), ensuring even surface without defects for easy product release

EDM Coatings & Overlaying

放電加工

The SparkDepo utilize the principles of EDM and delivers high-quality coatings and overlayings that meet requirements for wear, heat, corrosion, and oxidation resistance

SparkDepo (Electro-Spark Deposition)

The squares show surfaces ranging from fine to increasingly coarse
