The Wax Dipping Tank is a specialized auxiliary unit in the AAC (Autoclaved Aerated Concrete) panel production line. Its primary function is to coat steel rods (used as tension anchors or spacers) with wax before insertion into the molds. This waxing process is critical to ensure smooth rod extraction after pre-curing, avoiding damage to the green body and preventing slurry adhesion on the rods.
By ensuring clean and safe rod removal, the Wax Dipping Tank contributes significantly to product integrity, surface quality, and overall molding precision in AAC panel manufacturing.

Working Principle
● The tank is filled with paraffin wax, which is heated into liquid form using waste steam discharged from the autoclave—a sustainable and energy-efficient method.
● Steel rods are immersed into the molten wax, forming a thin, uniform coating over their surface.
● The wax layer serves as a non-stick barrier, allowing the rods to be easily pulled out of the mold after the green cake is set, without breaking or disturbing the internal structure.
Advantages & Key Features
Protects Product Integrity
● Prevents green body cracking, tearing, or edge collapse caused by rod removal, ensuring higher yield and quality consistency.
Energy Recycling and Efficiency
● Utilizes autoclave exhaust steam to melt the wax, reducing additional energy consumption and enhancing overall energy utilization efficiency of the plant.
Easy Rod Extraction
● The wax coating reduces friction and slurry adhesion on the rod surface, enabling smooth, damage-free demolding.
Stable Heating System
● Features controlled temperature regulation, ensuring the wax remains at optimal viscosity for coating, avoiding over- or under-heating.
Corrosion and Wear Resistant Structure
● Constructed with anti-corrosive materials, suitable for high-humidity environments, ensuring long equipment life and low maintenance.
Supports Continuous Operation
● Designed to handle batch dipping cycles efficiently, supporting the fast pace of modern AAC production lines.
The Runding Wax Dipping Tank is an essential safeguard in AAC mold demolding operations. By preventing material damage during steel rod extraction, it ensures high product qualification rates and supports precision molding, automation compatibility, and energy-saving production workflows.
