In terms of core technology research and development, Luhong Plastic Machinery focuses on the three major directions of intelligence, energy saving, and high precision, and continues to break through technical bottlenecks.
The company’s self-developed blow molding machine adopts imported PLC and hydraulic servo control technology, and is equipped with an intelligent human-machine dialogue display screen to achieve precise control and real-time monitoring of equipment operating parameters, greatly improving operation convenience and production efficiency.
In response to the production needs of large-volume chemical barrels, plastic pallets and other products, the company optimized the design of the plasticizing system and adopted a high-efficiency screw and barrel structure. It has strong plasticizing capacity, high homogeneity, and reduces energy consumption by more than 15% compared with industry standards, in line with national green and low-carbon development requirements.
At the same time, Luhong Plastic Machinery pays attention to the collaborative innovation of industry, academia and research, and has established long-term cooperative relationships with many domestic universities and scientific research institutions to jointly carry out the research and development and application of new blow molding technologies, new processes and new materials, and accelerate the transformation of scientific and technological achievements.
Through continuous technological innovation, the company has successfully overcome industry problems such as wall thickness uniformity control of large-volume products, high-speed molding stability, and multi-material co-extrusion. Its leading products have won provincial science and technology progress awards many times, and its technical strength has been recognized by industry authorities.
3. Full-chain layout: multiple products covering the needs of all scenarios
With profound technical accumulation and rich industry experience, Luhong Plastic Machinery has built a complete product matrix that can meet the production needs of hollow products of different industries, different specifications, and different materials, and achieve “one-stop” equipment solution supply.
In the field of packaging containers, the company’s plastic barrel equipment and chemical barrel equipment can produce 20L – 2000L various types of plastic barrels, chemical barrels, and IBC ton barrels. The products have the characteristics of high strength, corrosion resistance, and good sealing, and are widely used in liquid packaging in chemical, pharmaceutical, food, daily chemical and other industries.
The equipment adopts an advanced wall thickness control system to ensure uniform wall thickness of the product and excellent drop resistance. It has passed the 1.8m height free fall test and meets the safety requirements for packaging and transportation of hazardous chemicals.
In the field of logistics and warehousing, Luhong Plastic Machine Pallet Equipment focuses on the production of plastic pallets, turnover boxes, logistics boxes and other products. The equipment uses high-strength molds and hydraulic drive systems, with stable molding pressure, strong product carrying capacity and long service life. It can replace traditional wooden pallets and is in line with the development trend of green and standardized modern logistics.
The daily production capacity of a single piece of equipment can reach up to 1,000 pieces, helping logistics companies achieve efficient and low-cost warehousing and transportation.
In the field of highway facilities, the company’s highway facilities and equipment can produce traffic facility products such as plastic anti-glare boards, isolation piers, road cones, speed bumps, and guardrails. The equipment is adapted to high-strength plastic raw materials such as HDPE and PP.
