Changzhou Dali Plastics Machinery Co., Ltd., as an innovative high-tech enterprise, has been focused on product innovation. We have successfully worked out the HDPE geomembrane production line for dam lining,which is plan to sell it out to the global markets. HDPE geomembrane production line for dam lining is a good example to showcase our research and development capability. Changzhou Dali Plastics Machinery Co., Ltd. will introduce more advanced and innovative technology, and will gather more professional talents together.

HDPE geomembrane production line

Adopting casting film process to heat,extrude,press,cool HDPE, LDPE, MDPE,EVA and other raw materials.

Process:

• Feeding systems with pneumatic or helix loaders
• Extruder with screen changer
• Co-extrusion feedblocks for adjustment of layer ratio and layer distribution
• Flat Extrusion Die-heads
• Chill rolls where extruded melt is transformed into a film and quickly cooled down
• In-line triming equipment
• Sheet guiding system
• Surface winding unit
• Edge trim recycling system  

Raw Materials & Finished Product Applications

Polymers of LDPE, LLDPE, HDPE, EVA can be efficiently extruded on DL series of geomembrane extrusion line. Also used for coating many kinds of non-woven fabrics, woven fabrics,and getextile.

Geomembrane applications:

• Sanitary project(Landfill,sewage treament,toxic and hazardous compounds disposal)
• Water conservancy(river,lakes water reservior dam seepage control)
• Construction projects(subway construction, roof garden, sewage pipe liner)
• Lanscape Works(artificial lake, pool)
• Agriculture engineering(reservior, drinking water tanks, water storage pond, irrigation system)
• Transportation(railway,highway)
