Our Wood Finish Coating Process

Pretreatment

The aluminium surface is thoroughly cleaned and treated to ensure strong adhesion and corrosion resistance.

Wood Coating Base Layer

A specially formulated powder is sprayed onto the surface to create a smooth and adhesive base coat — usually in a neutral or wood-compatible color.

Sublimation / Heat Transfer Process

Using sublimation technology, wood grain patterns are transferred onto the coated aluminium using high-temperature vacuum heat. This results in an incredibly realistic wood appearance with depth, texture, and intricate grain lines.

Why Wood Finish Matters

01

Surface Preparation

The aluminium surface is thoroughly cleaned, degreased, and chemically treated to remove impurities and ensure proper adhesion of the coating.

02

Base Coat Application

A high-quality powder base coat (usually in a light color) is evenly applied to the aluminium surface and then baked to form a smooth, durable foundation.

03

Sublimation Film Wrapping

A special heat-resistant film printed with the desired wood grain pattern is wrapped tightly around the coated aluminium profile.

04

Heat Transfer (Curing)

The wrapped aluminium is heated in a curing oven, allowing the wood pattern from the film to transfer and fuse onto the surface through sublimation.

05

Film Removal and Inspection

After cooling, the film is removed, revealing a realistic wood-grain finish. Each piece is inspected for color uniformity, texture quality, and overall finish before delivery.

Salient Features

Plant Salient Features

Pre-Treatment

System Includes degreasing, deoxidizing, chromating for strong adhesion.

Powder Coating Booth

Wood-tone base coat application and curing at 180–200°C in a coating booth.

Sublimation Process

Heat-transfer film (wood grain) using vacuum/pressure application.

Sublimation Oven

160–200°C for 10–15 mins; ink turns to gas and penetrates base.

Film Types

Thermal transfer PET films (oak, teak, walnut, cherry, etc.).

Final Curing & Cooling

Post-sublimation curing and cooling chamber to stabilize parts.

Handling System

Automatic conveyors, customized jigs, and linear/U layouts.

Quality Control

Visual, adhesion (crosshatch), gloss, color, and UV/weather testing.

Environmental & Safety

ETP, dust/fume extraction, and non-chrome and VOC-free materials.
