Sure Plastic Machinery's wood-plastic extrusion equipment fully introduces servo motors
At a time when the plastic machinery industry is accelerating its transformation towards intelligence and efficiency, Sure Plastic Machinery, relying on its technological innovation strength, has taken the lead in applying servo motors on a large scale in the field of wood-plastic extrusion equipment, demonstrating its technological advantages with hard-core data and setting a new benchmark for efficient production in the industry.
The performance difference between servo motors and ordinary asynchronous motors has been fully verified in Sure Plastic Machinery's equipment. In terms of speed control accuracy, the speed fluctuation of the servo motor can be controlled within ±0.1%, while the fluctuation range of ordinary asynchronous motors is as high as ±1% - 5%. Taking the production of high-precision wood-plastic profiles as an example, Sure Plastic Machinery's equipment driven by servo motors can stably control the profile size tolerance within ±0.2mm, and the scrap rate is reduced by about 60% compared to equipment using ordinary motors.
In terms of response speed, the torque response time of the servo motor reaches milliseconds (within 10ms), while ordinary motors require 0.1 - 1 seconds. During the wood-plastic extrusion process, when the material viscosity suddenly increases due to formula adjustment or temperature change, the Sure equipment equipped with a servo motor can instantly adjust the torque output to maintain stable extrusion pressure, avoid defects such as welding marks and bubbles on the surface of the product caused by pressure fluctuations, and increase the product yield by about 35%.
Energy consumption data more intuitively shows the advantages of servo motors. Sure Plastic Machinery's actual measurement shows that an extruder driven by a 100kW servo motor can reduce energy consumption by 30% - 50% in 6,000 hours of annual operation compared to an asynchronous motor of the same power, which saves about 60,000 to 100,000 yuan in electricity bills. The servo motor also has an energy feedback function. When the equipment slows down or brakes, it can convert mechanical energy into electrical energy and feed it back to the power grid, further improving energy efficiency.
The durability and maintenance cost of the equipment are also significantly different. The servo motor adopts high-precision bearings and seals, with an average life of more than 100,000 hours, and the brushless design reduces the replacement of wearing parts. The average annual maintenance cost is only 1/3 of that of ordinary motors. Sure Plastic Machinery customers reported that after using servo motors to drive equipment, the annual downtime for equipment maintenance was reduced from about 120 hours to less than 40 hours, and production efficiency was greatly improved.
In terms of multi-axis collaborative control, servo motors support bus communication protocols such as EtherCAT and CANopen, and can achieve multi-unit speed synchronization of extruders, tractors, cutters, etc., with a synchronization error of ≤0.1%; while ordinary motors are controlled by analog signals, and the multi-axis synchronization error is ≥1%. This enables Sure Plastic Machinery to accurately match the operating parameters of each link when producing complex wood-plastic products to ensure production stability.
The technical director of Sure Plastic Machinery said: "We have conducted in-depth research on the pain points of wood-plastic production enterprises, and through the large-scale application of servo motors, we help customers achieve high-precision production, reduce energy costs, and improve equipment stability. Take a certain wood-plastic product enterprise as an example. After introducing Sure's extrusion equipment equipped with servo motors, the annual production capacity increased by 40%, the unit product energy consumption decreased by 38%, and the market competitiveness was significantly enhanced."
With the full popularization of servo motors in Sure Plastic Machinery's wood-plastic extrusion equipment, it will not only create significant economic benefits for customers, but also is expected to lead the trend of technological upgrading in the plastic machinery industry and promote the wood-plastic industry to accelerate towards green, intelligent and efficient directions.
