Modified & Regenerative Factory Upgrades Production with 230 Type Plastic Extruder for High-Yield, Energy-Saving and Non-Stop Mass Production
With intensified competition in the plastic regeneration and modification industry, equipment stability, production capacity, energy consumption and finished product quality have become the core factors of factory profitability. A plastic factory in Henan focusing on waste plastic recycled granulation and powder filling modification has long adopted ordinary small and medium-sized plastic extruder equipment, with increasingly prominent equipment defects. Ordinary screws have poor wear resistance, prone to scratching and carbon deposition when processing sediment-containing waste mixed materials, requiring frequent disassembly, maintenance and accessory replacement every month with high operation and maintenance costs. Traditional resistance heating has high energy consumption and large temperature difference, often causing material carbonization and uneven plasticization, resulting in uneven particle appearance and low-price sales. Frequent shutdown screen changes interrupt the production rhythm, limiting output and causing serious waste accumulation, trapping the factory in a long-term state of low profit and high loss and preventing it from undertaking high-end modified orders. To break through production bottlenecks, the customer inspected multiple models on-site and finally launched our high-end 230 type plastic extruder, realizing comprehensive production upgrading.
The customer mainly engages in PE and PP waste plastic recycled granulation and calcium carbonate filled modified particle production. The processing materials include a large number of cleaned wet mixed materials, fine sediment-containing recycled materials and high-powder filled modified materials, which put forward extremely high requirements for equipment wear resistance, extrusion pressure, temperature control accuracy and continuous production capacity. The original small extrusion equipment has insufficient power and short screws with incomplete plasticization, leading to uneven mixing and unstable hardness of modified particles, as well as frequent black spots and carbonization defects on recycled particles. Frequent shutdowns for screen change and maintenance limit output growth, seriously restricting the factory’s scaled development and profit improvement.
After comparing multiple large and medium-sized extrusion equipment, the customer finally selected the 230 type plastic extruder to solve the problems of fast equipment wear, high energy consumption, low output and poor quality. Its comprehensive advantages of high-end wear-resistant structure, electromagnetic energy-saving temperature control, non-stop continuous production and high-power stable extrusion fully match the factory’s mass production demands for complex materials, bringing immediate improvement effects after commissioning.
In terms of wear-resistant stable production and plasticization quality improvement, the 230 type plastic extruder completely solves the problems of poor material plasticization and easy equipment damage. The 230-specification 3.8-meter extended wear-resistant screw is made of 40CR high-frequency quenched and strengthened material, matched with a wear-resistant alloy reinforced feeding port, specially designed for processing sediment-containing recycled materials and high-fill modified materials. It is not easy to wear, accumulate carbon or scratch during long-term operation, greatly extending the service life of accessories and eliminating frequent disassembly and maintenance troubles. The 45# steel high-frequency treated barrel has a smooth inner wall without material hanging, avoiding residual material carbonization.
The 110KW high-power motor matched with a 375-type high-torque hardened gear reducer provides sufficient extrusion power and stable pressure. The extended screw greatly prolongs the material mixing stroke, realizing uniform melting and sufficient mixing for both soft recycled materials and high-hardness modified materials. The finished particles are compact, transparent, spot-free, carbonization-free and uniform in texture, successfully helping the customer undertake high-end modified product procurement orders.
In terms of energy-saving cost reduction and continuous mass production, the two core configurations greatly reduce the customer’s production costs. Three sets of 80KW electromagnetic zoned heaters replace traditional resistance heating, realizing fast and uniform heating, completely solving local material burning and uneven plasticization problems. The stable and high-quality finished products gain higher market premium, while power consumption is greatly reduced with considerable monthly electricity cost savings.
The 400-type hydraulic non-stop left-right screen changing head is equipped with a 4KW hydraulic pump station for stable pressure supply, realizing automatic alternating screen replacement without shutdown or strip breakage. It eliminates manual screen disassembly and replacement, saving labor costs and completely removing production interruption and waste loss caused by screen change shutdowns. The equipment’s effective operating rate is greatly improved with a significant increase in daily output. Matched with the 15KW 500-type forced feeder, it realizes uniform forced feeding without feeding jamming or bridging, maintaining a stable overall extrusion rhythm.
The full-machine national standard frequency conversion intelligent control is simple to operate and maintain. Veteran factory workers can master the operation quickly after simple training without professional technical staff on duty. The equipment body is reinforced with thick channel steel, featuring stable vibration-free operation and extremely low failure rate, requiring only simple daily cleaning and maintenance with ultra-low operation and maintenance costs.
The customer’s production supervisor commented: After upgrading to the 230 type plastic extruder, our factory completely got rid of low-end price competition. The quality of recycled and modified particles fully meets standards with higher order unit prices. The equipment is wear-resistant and durable with few maintenance needs, delivering sufficient output via non-stop production and saving electricity through electromagnetic heating. Labor, electricity and accessory losses are comprehensively reduced, and the equipment investment can be recovered in a short time. At present, we have realized 24-hour stable mass production and plan to add more identical equipment to expand production capacity.
This case fully verifies that the 230 type plastic extruder, with the core advantages of heavy-load wear resistance, energy-saving quality improvement and non-stop stable production, perfectly adapts to the mass production demands for complex materials in large and medium-sized regeneration and modification factories, serving as the preferred model for plastic extruder upgrading, quality improvement and profit growth.
