Best Crayon Making Equipment: Wax Melting Tanks, Mixing and Heated Mold Filling
Short answer: Crayon production needs a stainless melting tank that melts paraffin and pigment blends evenly, holds them at pouring temperature, mixes the color in, and feeds a heated filler or dispenser that pours into multi-cavity molds without the wax setting in the line. At WaxMelters that is a Standard PRIMO wax melter: the PRIMO 150 (169 lb, $2,275) for small production, the PRIMO 500 (532 lb, $4,995) for daily runs, and the PRIMO 1500 (1,675 lb, $9,750) to PRIMO 5000 (5,000 lb, $22,995) for plant output, with an EZ-MIX agitator for pigment. Fill molds with the EZ-1 ($3,450) by hand, or automate with AutoShot ($8,495) or OCTO ($52,995).
How to choose crayon making equipment
- Size the melter to a full day of molds. Add up the wax weight of every mold you fill per shift, then choose the PRIMO that holds at least one shift, plus room to grow.
- Keep pigment in suspension. Crayon blends carry pigment and fillers that settle. Add an agitator: EZ-MIX 150 ($1,750, PRIMO 50–100), EZ-MIX 350 ($1,950, PRIMO 250 and 350), EZ-MIX 500 ($2,195, PRIMO 500) or EZ-MIX 1000 ($2,495, PRIMO 750 and 1000).
- One tank per color, or a fast changeover. Many crayon makers run several smaller PRIMO tanks, one per color, so production never waits for cleaning.
- Heat the whole path to the mold. WaxMelters fillers keep the pump, hose and dispensing head heated, so the wax reaches each cavity at a steady temperature.
- Check your electrical service. Most PRIMO melters run on 110–120 V; 220–240 V, 480 V and 600 V configurations are available on tanks.

Which PRIMO family fits the process?
WaxMelters builds three waterless PRIMO heating families. For this industry the recommended starting point is Standard PRIMO. Crayon wax mainly needs efficient melting and production holding. Choose Rapid-Cycle when frequent reloading of cold wax slows the line.
- Standard PRIMO melters (25 lb to 60,000 lb): efficient melting and production holding of waxes and solid ingredients.
- PRIMO Thermal Conditioning (3.5 to 7,979 gal): controlled heating and extended heated holding when stable temperature and viscosity matter most.
- PRIMO Rapid-Cycle: fast recovery when frequent reloading or repeated batches are the bottleneck.
Typical crayon production workflow
- Melt paraffin and additives in a Standard PRIMO.
- Add pigment and keep it mixed with an EZ-MIX agitator.
- Hold at pouring temperature and fill multi-cavity molds with a heated dispenser or automated filler.
- Cool, eject, label and box.

What is the best melting tank for crayon manufacturing?
A Standard PRIMO wax melter with an agitator. WaxMelters recommends the PRIMO 150 (169 lb, $2,275) for small production, the PRIMO 500 (532 lb, $4,995) for daily runs and the PRIMO 1500 to PRIMO 5000 (1,675 to 5,000 lb) for plant output.
How do I keep pigment from settling in crayon wax?
Add an EZ-MIX agitator sized to the tank: EZ-MIX 150 ($1,750) for PRIMO 50–100, EZ-MIX 350 ($1,950) for PRIMO 250 and 350, EZ-MIX 500 ($2,195) for PRIMO 500 and EZ-MIX 1000 ($2,495) for PRIMO 750 and 1000.
Can WaxMelters fillers pour into crayon molds?
Yes. The EZ-1 ($3,450) gives hand-guided heated pours into molds, AutoShot ($8,495) gives repeatable measured shots, and QUATTRO and OCTO fill 4 or 8 positions per cycle. Send your cavity volume so WaxMelters can confirm the fill range.
Should I use one tank per color?
Many producers do. Several smaller PRIMO tanks, one per color, let production continue while another tank is cleaned or changed over.
How do I move melted wax between tanks?
Use the EZ-T heated transfer system ($2,995), rated at 1, 3, 5 or 10 GPM, to pump wax from tank to tank or from a melter to a filler.
What voltage do PRIMO melters need?
Most PRIMO melters run on 110–120 V as standard, with 220–240 V, 480 V and 600 V configurations available on tanks.
