Description
The Dupont edge profile delivers clean architectural lines that perfectly complement the modern aesthetic of porcelain slab countertops. This template is engineered specifically for laminated 2cm+2cm porcelain construction (1-9/16 inches total thickness) with specialized parameters that address porcelain's unique characteristics including extreme hardness, brittleness, and susceptibility to edge chipping. The stepped design creates visual depth while showcasing porcelain's consistent color and pattern throughout the edge profile, a key advantage of through-body porcelain materials. Porcelain's industrial manufacturing process creates a material harder than natural granite but more brittle, requiring careful machining to prevent micro-chipping along edges. This template specifies standard RPM settings (2800-4000 range) similar to granite, but fabricators must use diamond tooling specifically rated for porcelain and maintain sharp cutting edges throughout the process. The 9-position polishing sequence progresses from 50 grit metal bond through 3000 grit resin bond and final buff, producing a stunning polished edge that highlights porcelain's modern aesthetic. Premium pricing of $21.60 per linear foot reflects the specialized expertise required for flawless porcelain edge fabrication.

Installation Overview
Fabricating the Dupont edge on laminated porcelain requires meticulous attention to prevent edge chipping and micro-cracking. Verify the porcelain lamination bond has cured fully (porcelain adhesives often require longer cure times than natural stone). Support the slab edge with rigid backing during machining as porcelain transmits vibration readily through its dense structure. Use 25mm roughing finger bits specifically designed for porcelain at 3500 RPM with very sharp cutting edges. Dull tooling will cause catastrophic chipping on porcelain edges. Feed rates should be moderate (70-90 IPM) with shallow depth of cut (2mm maximum) to minimize cutting forces. The straight geometry of the Dupont profile helps reduce edge stress compared to curved profiles. Execute the seam polishing pass at 2500 RPM with light consistent pressure to blend the lamination line. Progress through the polishing sequence from 50 grit onward, inspecting the edge after each position for any micro-chips that may require spot remediation. Total fabrication time is 35-45 minutes per linear foot due to the careful approach required for porcelain.
CNC Cutting Notes
CNC programming for porcelain demands conservative cutting parameters despite the material's hardness. Use 25mm diamond-coated finger bits rated specifically for ceramic and porcelain materials at 3500 RPM. Standard stone tooling may chip or fail on porcelain's abrasive surface. Program shallow depth of cut (1.5-2mm per pass) and moderate feed rates (70-90 IPM) to prevent excessive cutting forces that lead to edge fracture. The stepped Dupont geometry creates internal corners that are particularly vulnerable to chipping, so ensure tool paths have small radius transitions rather than sharp direction changes. During polishing, start with 50 grit metal bond at 2800 RPM and progress through the sequence to 4000 RPM for final passes. Porcelain requires diamond abrasives throughout as silicon carbide abrasives wear too quickly. Maintain continuous water flow to control porcelain dust (which is extremely fine and abrasive) and prevent heat buildup. Porcelain doesn't show heat discoloration like natural stone, but thermal shock from uneven heating can cause micro-cracks. Inspect edges with magnification after machining to detect any micro-chips that may propagate into larger damage during installation.
Material Compatibility
This template is optimized for large-format porcelain slab materials in laminated 2cm+2cm construction. Compatible with all major porcelain brands including Neolith, Laminam, Maxfine, Sapienstone, and others. Porcelain's through-body composition means edge color and pattern match the surface exactly, unlike some materials where the edge may show different characteristics. The material's extreme hardness (Mohs 7-8) and brittleness require diamond tooling specifically rated for ceramics. Porcelain's consistent manufacturing quality produces predictable machining results across different colors and patterns. The laminated construction provides adequate thickness for the stepped Dupont profile while maintaining the thin-slab aesthetics that define modern porcelain applications. For solid 3cm porcelain or non-laminated 2cm, use the appropriate thickness-specific templates.
