HUAYU High‑Efficiency 3‑Layer Co‑Extrusion 220L Double L‑Ring HDPE Chemical Drum Blow‑Molding Machine

Huayu 220L Double Ring Drum Blow Molding Machine is a fully automatic extrusion blow molding equipment specially developed for mass production of 220-liter HDPE double ring chemical barrels and industrial plastic drums. Adopting mature extrusion blow molding technology and optimized mechanical structure, this machine realizes stable, continuous and high-precision production of large hollow containers, widely applied in chemical storage, industrial packaging, logistics transportation and other fields.
The equipment features an integral high-rigidity frame and optimized clamping structure, ensuring strong clamping force, stable mold closing and excellent shock resistance during long-term high-load operation. The exclusive parison wall thickness control system precisely adjusts material output in real time, effectively controlling the wall thickness distribution of the double ring drum. The finished products feature uniform thickness, smooth surface, stable structural strength and excellent anti-leakage performance, fully meeting the standard requirements of industrial packaging containers.
Equipped with a high-efficiency plasticizing extrusion system, the machine ensures sufficient and uniform raw material melting with stable extrusion flow, effectively avoiding material melting defects and material waste. The whole production process from feeding, plasticizing, parison extrusion, mold clamping, blowing, cooling to demoulding is automatically completed, greatly reducing manual intervention and improving production efficiency and product consistency.
This blow molding machine supports single-layer and multi-layer customized production according to customer demands. The produced 220L double ring barrels have good pressure resistance, weather resistance and environmental stress cracking resistance, suitable for holding daily chemical materials, industrial raw materials and common liquid mediums. With low energy consumption and low failure rate, the equipment can operate stably for a long time and adapt to continuous industrial batch production.
All core accessories adopt high-standard industrial components with stable performance and long service life. The humanized operation interface is simple and intuitive for parameter setting, equipment monitoring and daily operation. Complete safety protection devices ensure safe and reliable workshop production.
As professional large hollow blow molding equipment, Huayu 220L double ring drum blow molding machine provides reliable container manufacturing solutions for medium and large packaging factories, helping customers improve product quality, expand market competitiveness and achieve stable and efficient production benefits.
