MIX INJECTION SYSTEM

Mix Injection System for Fragrance, Color & Additive Dosing

The WaxMelters Mix Injection System is a post-melt dosing and inline mixing platform designed for manufacturers who need to run multiple fragrances, colors, or additives without contaminating the main wax melter.

Instead of mixing fragrance or color directly into the primary tank, this system introduces the material downstream after the wax has been melted. This keeps the main melter clean, reduces changeover time, and allows operators to switch between products more efficiently.

Designed for Multi-Fragrance Production

This system is ideal for candle manufacturers, private label producers, and contract filling operations that run many fragrances or colors throughout the day.

Each dosing line is independent and can be used for fragrance, color, pre-mixed fragrance/color blends, or other liquid additives.

How the System Works

Clean melted wax flows from the melter into the Mix Injection System. Fragrance, color, or additives are metered into the wax stream through dedicated dosing lines. The combined material then passes through an inline static mixer before being dispensed.

This allows the base wax to remain clean while the final fragrance or color is added only at the point of use.

Base System Includes

• Expandable injection manifold
• One universal dosing line
• Inline static mixing section
• Heated transfer connection
• Temperature and pump control interface
• Industrial stainless steel construction

Expandable Dosing Lines

The base system includes one dosing line. Additional dosing lines can be added as options.

Each additional line is dedicated and independently controlled, allowing customers to configure the system around their own production workflow.

• Use one line for fragrance
• Use one line for color
• Use one line for a pre-mixed fragrance/color blend
• Add multiple lines for fast changeover between products

Advantages

• Keeps the main wax tank clean
• Reduces cross-contamination
• Speeds up changeover between products
• Reduces wasted material
• Improves production flexibility
• Allows one melter to support many SKUs

Common Configurations

Configuration	Best For
1-Line System	Basic fragrance, color, or additive injection
2-Line System	Basic fragrance & color additive injection
3-Line System	Small production teams running multiple products
5-Line System	Manufacturers running many fragrances or colors daily
10-Line System	High-volume or private label production environments

Compatible Applications

• Candle wax fragrance dosing
• Color dye injection
• Private label candle production
• Multi-fragrance production lines
• Post-melt additive dosing
• Specialty wax and molten product filling

Compatible Equipment

The Mix Injection System can be configured with select WaxMelters melting and filling systems, including PX, AS3000-AS4500-AS9000 and QUATRRO-OCTO-DUODECIM-SEDECIM Systems.

System configuration depends on wax type, flow rate, temperature, viscosity, number of dosing lines, and desired production workflow.

Important Notes

Each dosing line is designed as a universal line. It does not need to be permanently assigned as fragrance-only or color-only. Customers may use each line for fragrance, color, additives, or pre-mixed blends depending on their process.

For best performance, each fragrance or color used for fast changeover should have its own dedicated dosing line.

Base System Starts at $24,995.

Additional dosing lines are available as options.

Industrial Wax Mixing & Fragrance Injection System

The WaxMelters Mix Injection System is designed for industrial wax processing, candle manufacturing, and molten product filling applications where multiple fragrances or colors must be handled efficiently.

This system provides inline fragrance and color injection, improving consistency while reducing contamination and downtime.

System Design & Operation

The Mix Injection System is designed to integrate directly downstream of a melting or filling system, allowing fragrance, color, or additives to be introduced into the wax stream after melting.

Material flows from the melter into the injection manifold, where one or more dosing lines introduce controlled amounts of fragrance or color. The combined material then passes through an inline static mixing section before being dispensed.

Independent Dosing Line Architecture

Each dosing line operates independently and is designed to pull material directly from a dedicated container. This allows operators to stage multiple fragrances or colors at once without cross-contamination.

• Each line includes its own metering pump and injection point
• Lines can be activated individually based on the product being run
• No shared lines between fragrances unless intentionally configured

Production Workflow Advantages

Fragrance and color are added inline at the point of fill, saving cleaning time and material and keeping production moving.

With post-melt injection, the base wax remains unchanged while final formulation occurs inline. This allows a single melting system to support multiple products in the same production cycle.

Changeover Process

Switching between products typically involves selecting a different dosing line and allowing a short transition period through the mixing section. This is significantly faster than draining and cleaning a full tank.

For operations running multiple fragrances per day, dedicated dosing lines for each material provide the fastest and cleanest workflow.

Material Compatibility

The system is designed for use with molten wax and compatible liquid additives including fragrance oils, dyes, and other formulation components.

Final configuration may vary depending on viscosity, temperature, and flow rate requirements.

System Integration

The Mix Injection System is compatible with WaxMelters PX Series filling systems and OCTO Flex melting systems. It can also be configured to integrate with existing heated transfer and dispensing setups.

System sizing and configuration depend on:

• Wax type and operating temperature
• Required flow rate
• Number of dosing lines
• Production volume
• Dispensing method

Expansion & Future Scaling

Additional dosing lines can be added as production requirements increase. This allows the system to scale without replacing the core equipment.

This modular approach supports growing product lines, seasonal variations, and private label production without requiring additional melting systems.
