Double-Color EVA Injection Molding Machine 24-Station Rotary

Double-Color EVA Injection Molding Machine 24-Station Rotary
Product Overview

The Double-Color EVA Injection Molding Machine with 24-Station Rotary Table is a premium shoe sole manufacturing system capable of producing two-color EVA soles in a single production cycle. The 24-station rotary design maximizes throughput while the dual injection units enable complex two-tone and two-material sole designs popular in modern athletic and fashion footwear.

Each of the 24 mold stations rotates through injection, cooling, and ejection zones automatically. The PLC control system independently manages both injection units, allowing different colors or even different EVA compound formulations to be injected sequentially into the same mold. The result is a perfectly bonded two-color sole without the need for secondary gluing or assembly.

With production capacity reaching 120-180 pairs per hour and rapid mold change capability, this machine is the ideal choice for factories serving major sports brands that demand high-quality two-color EVA soles with fast turnaround times.

Key Features
  • 24-station rotary table for continuous high-throughput production

  • PLC multi-zone temperature control for consistent foaming
  • Hydraulic mold clamping with 80-ton force per station
  • Automatic mold release and ejection system
  • Quick mold change system (under 30 minutes)
  • 1 Year warranty

Frequently Asked Questions
Q: Can this machine produce single-color soles?
A: Yes, it can operate with just one injection unit active for single-color production, with the same high throughput.
Q: How are the two colors bonded together?
A: The first color is partially cured before the second color is injected. The heat and pressure during the second injection create a molecular bond between the two materials, resulting in a seamless integration.
Q: What EVA hardness range can be processed?
A: Shore C hardness from 35 to 75 can be processed. Different hardness values can be used for the two colors for dual-density applications.
Q: How long does it take to change molds?
A: Complete mold changeover for all 24 stations takes approximately 25-30 minutes with the quick-change system. Single station mold replacement takes under 5 minutes.
Q: What after-sales support is available?
A: We offer 1 year warranty, on-site installation and commissioning, operator training, and ongoing remote technical support. Spare parts are stocked in our warehouse for rapid delivery.
