Process Control

Machining Magnesium Safely and Consistently

Magnesium cuts efficiently, but chip handling, ignition control and heat management must be built into the process.

01

Chip Control

Sharp tools and controlled evacuation prevent recutting and excess heat.

02

Fire Prevention

Dry chips are segregated and handled under dedicated safety procedures.

03

Stable Workholding

Balanced clamping protects thin walls and lightweight structures.

04

Controlled Deburring

Edges are finished without damaging thin or coating-ready features.

Surface Protection

Finishes for Magnesium Parts

Select the process by corrosion exposure, wear, coating thickness, appearance and electrical requirements.

Chemical conversion coating on magnesium part

Chemical Conversion Coating

Thin pretreatment for moderate corrosion protection and stronger coating adhesion.

Micro-arc oxidation treatment on magnesium alloy

Micro-Arc Oxidation (MAO/PEO)

Hard ceramic oxide layer for demanding wear and corrosion conditions.

Electroless nickel coated magnesium component

Electroless Nickel Plating

Uniform hard coating for complex geometry, wear resistance and corrosion protection.
