One-Stop Electrical Flange Manufacturer – Casting, CNC Machining & Surface Treatment | MegaloCast

One-Stop Electrical Flange Manufacturing – Casting + CNC Machining + Surface Treatment

MegaloCast is a full-service aluminum electrical flange manufacturer serving global power transmission, substation and high-voltage equipment clients. Unlike trading companies or single-process workshops, we control every stage in-house:

1. Casting (4 Processes Available)

• Sand Casting – Large diameter flanges (up to 1500mm+), low to medium volume

• Gravity Casting (Permanent Mold) – Medium volume, better surface, heat-treatable

• Low Pressure Die Casting (LPDC) – Low porosity, pressure-tight flanges

• High Pressure Die Casting (HPDC) – High volume, thin-wall complex shapes

2. In-House CNC Machining

• CNC turning, milling, drilling, boring, tapping

• Bolt-circle accuracy, sealing face flatness, concentricity control

• Dimensional inspection per customer drawing

3. Surface Treatment

• Anodizing (clear / brown / hard anodize) – Corrosion resistance for outdoor use

• Powder Coating – Color-matched, weather-resistant

• Shot Blasting – Surface preparation and cleaning

• Custom finishes available per specification

Why Global Buyers Choose Our Integrated Approach:

• No handoff delays between foundry, machine shop and coater

• Tight tolerance control from casting to final dimension

• Full traceability: one PO, one quality team, one shipment

• Cost savings: eliminate middleman markup and logistics

Typical Electrical Flanges We Produce:

• Substation structural flanges (Ø600mm – Ø1500mm+)

• Transformer & GIS bushing flanges

• Hollow composite insulator end flanges

• Porcelain/ceramic insulator flange fittings

• Power distribution equipment mounting flanges
