——Designed for Durable, Large-Scale Plastic Parts: Lisong’s Technical Expertise

Barrel containers are widely used across the chemical, food storage and transportation, sanitation, and household sectors. Available in a broad range of sizes—from a few liters to several hundred liters—they require excellent impact resistance, corrosion resistance, and reliable stackability. Given their large dimensions and high material consumption, these products place stringent demands on the plasticization capacity, clamping force, and overall stability of the injection molding equipment.

Building on years of accumulated technical experience, Ningbo Lisong Injection Molding Technology has developed specialized injection molding machine series for large barrel production. The equipment features a robust clamping structure and an enlarged injection unit to ensure complete mold filling while preventing defects such as flash or short shots. In addition, intelligent cushion control and multi-stage injection pressure adjustment functions contribute to a more uniform internal structure and enhance the overall strength of the barrel.

For example, in the production of chemical barrels, Lisong’s machines deliver outstanding performance in material plasticization homogeneity. They are particularly suited for processing high-viscosity materials such as high-density polyethylene (HDPE), producing finished barrels with consistent wall thickness and high durability. We also offer automated demolding and stacking solutions to help customers establish highly efficient, continuous production lines while reducing reliance on manual labor.

Lisong prioritizes in-depth communication with every customer. We are committed to collaborative optimization of process parameters and mold design, providing reliable support for high-quality, cost-effective barrel production.
