Three/Four-Color Upper Strap Injection Molding Machine

Multi-Function Machine for PVC Upper Straps and Soles
This machine is equipped with a multi-function operating system and is specially designed for producing single-color, two-color, three-color, and four-color PVC sandal and slipper uppers.
It can also produce soles for children’s and women’s footwear at the same time, offering greater production flexibility.

Cost-Effective Main and Auxiliary Machine Design
The simplified frameless design for the main and auxiliary machines helps reduce equipment cost and lower the customer’s overall purchasing investment.
This makes the machine a more economical choice for manufacturers seeking efficient PVC footwear production.

Industrial HMI for Easier Operation
The machine adopts an industrial-grade human-machine interface with a larger touchscreen display and PLC communication control system.
This makes operation easier and more intuitive, helping reduce operator difficulty and improve working efficiency.

Automatic Sectional Mold Clamping System
The machine is equipped with an automatic sectional mold clamping mechanism.
According to mold thickness, it can automatically adjust between fast and slow clamping stages, ensuring both production speed and effective mold protection.

Higher Output with Lower Energy Consumption
With a more optimized electromechanical configuration, the machine can increase output by approximately 15% under the same configuration conditions.
It is designed to achieve low energy consumption and high productivity, helping manufacturers improve cost performance.

Improved Four-Column Structure for Better Stability
Both the main machine and auxiliary machine adopt an improved four-column structure, which offers less deformation, longer service life, and higher product stability.
This helps ensure more reliable machine performance during long-term production.

Optional Air-Cooling System
An optional air-cooling unit is available, allowing the complete machine to operate without water circulation.
This helps achieve more environmentally friendly and energy-saving production.

Optional Dual-Proportional Hydraulic System
The optional dual-proportional hydraulic system allows both pressure and flow to be adjusted, making operation more convenient and more reasonable.
It also helps improve product consistency and production stability.
This configuration is available for the 80T four-column model.
