Hard Chrome Plating
Hard chrome plating deposits a hardened chromium layer onto industrial components, built to outlast the base metal it protects. Powernox applies it for automotive tooling, metal stamping, mould and die, and precision engineering work across Malaysia, plating new components and restoring worn ones since 2002.
What It Does
A hardened layer, not a filler.
Hard chrome plating is an electroplating process: chromium is deposited from solution onto a prepared component surface under controlled electrical current, building a dense, hard-bonded chromium layer over the base metal. It is a precision finishing process, not a repair filler — existing pitting, scoring, or significant defects should be corrected, typically by grinding, before a component is plated.
Complex geometries and tight internal features can affect how evenly a surface plates, so suitability is assessed job by job rather than assumed.
Surface Hardness
The plated layer is substantially harder than most tool and engineering steels, without hardening or distorting the base component.
Wear & Abrasion Resistance
A harder working surface resists scoring, galling, and abrasive wear on components under repeated mechanical load.
Corrosion Protection
The chromium layer forms a barrier against moisture and everyday industrial chemical exposure.
Low-Friction Surface
A smooth, low-friction finish reduces drag on moving and reciprocating components, and resists galling under load.
Restoration of Worn Surfaces
Suitable worn components can be built back up and replated rather than scrapped and remanufactured.
Where It's Used
Industries and applications.
Hard chrome plating supports a wide range of industrial components. The following reflects Powernox's primary industry focus — the same capability runs across all five, not automotive alone.
Automotive
Dies, tooling, shafts, and wear surfaces on manufacturing equipment.
Automotive stamping dies · Tool inserts · Precision tooling
Metal Stamping
Tooling and wear-critical surfaces that see repeated cycles.
Punches · Cutting tools · Stamping dies
Mould & Die
Precision surfaces for plastic injection and metal forming.
Mould and die components · Plastic injection moulds
Precision Engineering
Components requiring controlled surface treatment and verified finish.
Pump shafts · Gear shafts · Precision tooling
General Manufacturing
Tooling, shafts, and wear parts across broader plant equipment.
Hydraulic rams · Hydraulic cylinders · Fork tubes · Packaging formers
Finish Specification

Surface Finish
Materials
Suitable for steel, tool steel, stainless steel, copper, brass, and selected aluminium alloys. Suitability depends on the specific material, condition, geometry, and required result — it is confirmed per job, not assumed.
Plating Capacity
Powernox's hard chrome lines run on two chrome tanks, 3000A and 6000A rectifiers, and a 5-ton overhead crane for handling larger components.
The Hard Chrome Process
From raw component to hardened surface.
Component Assessment
Inspection and requirement review confirm the material, condition, and finish a job needs before work begins.
Surface Preparation
Degreasing and surface preparation give the component a clean, suitable base for plating.
Precision Masking
Areas outside the required plating zone are masked with the same care given to the plating itself.
Controlled Hard Chrome Plating
Chromium is deposited under controlled current to build the required hardened layer.
Grinding & Polishing
Grinding and polishing bring the plated surface to the required dimension and finish where needed.
Final Quality Inspection
Coating thickness, hardness, and surface roughness are checked before a component ships.
Lead time: 3–5 working days, subject to job requirements
Service Life
Getting the most from a plated surface.
Hard chrome plating extends service life, but it isn't maintenance-free. A few general care principles help a plated component perform for longer — none of them are guarantees, since actual service life depends on the application and operating conditions.
Regular cleaning to keep the plated surface free of abrasive debris
Suitable lubrication on moving and reciprocating components
Avoiding unnecessary shock loading on the plated surface
Periodic inspection to catch early scoring or pitting
Clean, dry, non-corrosive storage where applicable
