                                               High speed wax saturation machine for corrugated boxes 

                                                   Model 1400x1100

a wax soaking machine is a critical investment for producers of corrugated cartons that must perform in the most challenging wet and cold environments, offering unmatched durability and waterproof protection.

How to Choose a Wax Soaking Machine

When selecting a machine, consider:

1. Production Volume & Speed: Determine your required output (boxes per hour). In-line systems are for high volume; offline for lower or batch production.
2. Box Size Range: Ensure the machine can handle the minimum and maximum blank sizes you need.
3. Wax Type: Confirm the machine is compatible with the wax blends you plan to use (e.g., 100% paraffin, paraffin-polyethylene blends).
4. Level of Automation: Do you need a fully automated line with auto-feed and stackers, or is a semi-automatic machine sufficient?
5. Energy Efficiency: Look for well-insulated wax tanks and efficient heating systems to control operating costs.
6. Footprint: Ensure you have adequate floor space for the machine and auxiliary equipment.
7. Supplier Reputation: Choose a manufacturer with a strong track record for reliability, service, and spare parts support.

Types of Wax Soaking Machines

There are two primary configurations:

1. In-Line Wax Soaking System:
· Description: Integrated directly with a corrugated box-making machine (folder-gluer). The flat, glued carton blanks go straight from the folder-gluer into the wax soaker.
· Advantages: Highly automated, minimal manual handling, ideal for high-volume, dedicated production runs. Maximizes efficiency.
· Disadvantages: Less flexible; the entire line is dedicated to waxed boxes.
2. Off-Line/Standalone Wax Soaking Machine:
· Description: A self-contained unit. Pre-made, flat carton blanks are fed into it manually or via a separate conveyor.
· Advantages: Flexible; can be used to wax boxes from various sources and in different sizes (with changeover). Can be added to an existing facility without modifying the main box production line.
· Disadvantages: Lower throughput than in-line systems and requires more manual labor.

· Unstacker/Feeder: Automatically feeds flat carton blanks into the conveyor.
· Pre-Heating Oven: Uses infrared or hot air to heat the blanks before waxing.
· Wax Tank/Main Bath: Heated, insulated vessel that holds the molten wax. Equipped with heaters and precise temperature controls.
· Conveyor System: Typically a chain-driven or belt system with flights or pins to carry the cartons through each stage. It is often designed to submerge and hold the boxes at an angle.
· Drainage Conveyor: A vibrating or tilted conveyor section for removing excess wax.
· Cooling Tunnel: A section with powerful fans (air cooling) or water misters to solidify the wax quickly.
· Stacker/Output: Automatically stacks the finished waxed boxes.
· Control Panel: PLC-based system to control temperature, conveyor speed, and timing.

Wax Spraying vs. Wax Soaking

It's important to distinguish between the two:

Feature Wax Soaking Machine Wax Spraying/Curtain Coater
Process Complete immersion in a wax bath. Wax is sprayed or poured over the box as a curtain.
Penetration Deep penetration into the core of the board. Primarily a surface coating; limited penetration.
Wax Add-On High (typically 40-60% of the box's weight). Lower (typically 20-40%).
Resulting Box Extremely strong, rigid, and waterproof. Water-resistant, but can delaminate under stress.
Cost Higher initial machine cost and wax consumption. Lower cost for both machine and wax.
Best For The most demanding applications (ice, fresh fish). Applications requiring good moisture resistance but not total immersion.
