Co-extrusion blow molding machine LBM series

for bottlesfor plastic bottlesmultilayer

Overview
Fully automatic hydraulic co-extrusion bottle blow moulding attachment designed for integration with 20 mm and 25 mm single‑screw extruders. Streamlined co‑extrusion dies provide optimized color dispersion and reduced purging during color changes. Configurable to produce single‑layer or multilayer (2‑ and 3‑layer) bottles in most blowable thermoplastic resins. Two models available: LBM‑125 (up to 125 ml) and LBM‑250 (up to 200–250 ml) with a larger hydraulic unit and increased clamping stroke.

Key features

• Fully automatic hydraulic attachment compatible with 20 mm and 25 mm single‑screw extruders
• Streamlined 2‑ and 3‑layer co‑extrusion dies for uniform layer distribution
• Adjustable parison thickness for precise layer ratios
• Minimal purging required for fast color changeovers
• Produces single‑layer and multilayer bottles in most blowable resins
• Two model options: LBM‑125 (≤125 ml) and LBM‑250 (≤200–250 ml)
