The Problem: OEMs Need More Than Just Raw Material
In modern transformer production, generic insulation sheets often fail to meet advanced electrical, thermal, and dimensional requirements.
OEMs repeatedly tell us:
- “Standard sheets don’t fit our coil geometry.”
- “Tooling delays slow down production.”
- “Manual shaping wastes labor and increases scrap.”
➡️ That’s why custom transformer pressboard has become essential—not optional.
Our Custom Pressboard Capabilities
We produce custom electrical insulation pressboard components tailored to your transformer design.
Key capabilities:
- CNC machining – ducts, pressure rings, notches, corner slots
- Thickness range: 0.3 mm to 60 mm (including pre-compressed)
- Formable profiles – for 3D structures like coil corners and arc barriers
- OEM-specific kits – labeled by part, packed by transformer
✅ Supported formats: DXF, DWG, STEP, physical templates
✅ Materials: IEC 60641 certified, SGS-tested on request
Customization reduces waste, saves time, and ensures dielectric consistency.
