开创可持续性的吹塑行业解决方案

STONE and ST Blowmoulding Group is spending huge efforts on R&D activities to enhance the efficiency of the machines designed and manufactured to reduce the Carbon Footprint (CF).
It is a clear vision of the Entrepreneurs and Stakeholders to give a solid shape of innovation to the new BMM supplied in the present and future markets.
Our commitment focuses on reducing the carbon footprint of blow molding machines, addressing three critical environmental factors: energy consumption, raw material usage, and recycled material incorporation.
Advanced Energy Efficiency Solutions

Our machines achieve unprecedented energy efficiency through innovative features:

• Advanced heat insulation in the plasticizing section
• State-of-the-art synchronous reluctance motors for all extruders
• Variable speed hydraulic pumps for hydraulic machines
• Revolutionary "adiabatic" extruders featuring specialized screw and barrel design
• All-electric toggle-type clamping units

These innovations have enabled our machines to surpass EURMAP 46.1 Class 10 standards, achieving an exceptional energy consumption rate of 0.22 kWh/kg - significantly outperforming the industry standard of 0.38-0.40 kWh/kg.

This improvement translates to potential energy savings of up to 400,000 kWh annually.

Material Optimization Technology

We've revolutionized material consumption through precise parison control:

• Ultra-high resolution 500-point parison thickness profiling
• Advanced axial and radial dynamic thickness control
• Intelligent wall thickness optimization

Our dynamic radial control system eliminates excess material while maintaining structural integrity, resulting in lighter products, faster cycle times, increased production capacity, and reduced raw material consumption.

Case Study: L-Ring Drums Production

Our sustainability innovations demonstrate remarkable results in L-Ring Drums manufacturing:

Energy Efficiency:

• Standard industry consumption: 0.38-0.40 kWh/kg
• ST machines performance: 0.22 kWh/kg
• Annual production basis: 228,000 pieces (12 kg gross weight, 8.5 kg net weight)
• Potential energy savings: 400,000 kWh/year

Material Optimization:

• 10% weight reduction achieved through optimized wall thickness
• Annual raw material savings: 190 tons
• Additional energy savings: 140,000 kWh/year

Process Excellence and Waste Reduction

Our machines incorporate advanced process monitoring and control systems that:

• Ensure long-term process stability
• Maintain consistent product quality
• Reduce reject rates

A mere 5% reduction in reject rates for L-Ring Drum production can yield additional energy savings of 95,000 kWh annually.

Intelligent Manufacturing

ST and STONE plants feature comprehensive process monitoring capabilities:

 

• Advanced detector and transducer systems
• Real-time parameter monitoring
• Automated process adjustment
• Predictive maintenance capabilities
• Intelligent warning systems for parameter deviation

Our next-generation blow molding machines incorporate automated response systems, adjusting to process variations in real-time to maintain optimal production efficiency and product quality.

This technological convergence of energy efficiency, material optimization, and intelligent process control represents our commitment to sustainable manufacturing, delivering both environmental and economic benefits to our customers.
