This week, Hartek completed the production and commissioning of a laboratory two-roll open mill, which has been officially shipped to India.

Designed specifically for laboratory environments, this equipment is suitable for processes such as plasticizing, mixing, and hot-pressing of materials like rubber and plastics, and can meet the needs of small-batch, multi-batch sample production during the R&D phase.

Applications of the Laboratory Two-Roll Open Mill:

• Rubber and plastic formulation design
• Mixing and plasticizing of rubber and plastics
• Mixing and vulcanization of rubber
• Preparation of rubber and plastic sheets
• Optimization and control of rubber mixing process parameters

Product Performance of the Laboratory Two-Roll Open Mill:

• Steel rolls are motor-driven, ensuring stable speed control
• Steel roll surfaces are hard chrome plated and mirror-polished
• Automatic stop protection device with protective cover
• Adjustable working range
• Electric heating/oil heating options available based on process requirements
• Manually adjustable roller spacing
