Our  PMMA Extruder Machine Profile
Our acrylic (PMMA, polymethyl methacrylate) rod extruder is a plastic molding machine specifically designed for continuously processing PMMA granular raw materials into rod-shaped products through a "melt-extrusion-shaping" process. With its high efficiency, stability, and flexibility, it has become the core equipment for the large-scale production of acrylic rods and is widely used in decoration, industry, medical, and handicrafts. Through "physical melting + mold forming + precise shaping," it ensures the dimensional accuracy, surface quality, and mechanical properties of the rods, adapting to the needs of large-volume, multi-specification production.

Our PMMA Extruder Machine Advantages
1. High Production Efficiency, Adaptable to Mass Production
Continuous production mode increases capacity by 3-5 times compared to traditional casting processes (intermittent production). A single small machine can achieve a daily capacity of 500kg-1 ton, while large machines can reach 3-5 tons. No need to wait for mold cooling or demolding; continuous production is possible after startup, significantly shortening the production cycle.
2. Stable Product Quality and Excellent Performance
High Dimensional Accuracy: Outer diameter tolerance can be controlled within ±0.1-0.3mm, and length tolerance within ±1mm, far superior to casting processes (±1-2mm), meeting high-precision assembly requirements.
Excellent Surface and Transparency: Precise temperature control and optimized mold flow channels result in a smooth, scratch-free, bubble-free, and crystal-point-free finished product surface with a light transmittance ≥92% (close to PMMA raw material itself), suitable for direct use in transparent parts applications.
Uniform Performance: Thorough mixing and melting by the screw ensures uniform distribution of raw material molecular chains, resulting in consistent mechanical properties such as hardness, toughness, and weather resistance in the rods, without localized brittleness or deformation.
3. High raw material utilization and controllable cost
Scrap and waste generated during extrusion can be directly crushed and recycled, with a recycling rate of ≥90%. PMMA has good thermal stability, and secondary processing has minimal impact on product quality. Low raw material loss rate (≤5%) reduces raw material costs by 20%-30% compared to manual processing or casting.
4. Flexible specifications to meet diverse needs
Can produce rods with diameters from 3mm to 200mm (up to 500mm on some large-scale equipment) and arbitrary lengths (fixed length/unlimited length). Specifications can be quickly switched by changing the mold. Supports customized production: Can process acrylic rods with special functions such as colored, frosted, fluorescent, fiber-reinforced, and flame-retardant finishes to meet the personalized needs of different fields such as decoration, industry, and medical.
5. High degree of automation and convenient operation
Equipped with a PLC intelligent control system, core parameters such as temperature, screw speed, and traction speed can be precisely set and automatically adjusted, reducing manual intervention.
Some equipment supports remote monitoring, process parameter storage (can store 100+ sets of formulas), fault alarms, and other functions. Operation is simple, maintenance is convenient, and a single person can manage multiple machines.
6. Low energy consumption and good environmental performance
Energy consumption per unit capacity is more than 30% lower than that of injection molding machines. Infrared or electromagnetic heating coils are used, with a thermal efficiency of ≥85%, significantly reducing production energy consumption.
The production process produces no wastewater or exhaust gas emissions, and waste materials can be recycled, complying with environmental protection policies and reducing environmental pressure.
7. Fast return on investment and high cost-effectiveness
The unit price of the equipment is moderate (tens of thousands of yuan for small equipment and hundreds of thousands of yuan for large equipment). In mass production scenarios, thanks to high capacity and low loss, the investment can be recovered within 1-2 years. Compared with the injection molding process with high cost of customized molds, the extruder mold cost is lower (the price of a single mold is only 1/3-1/5 of that of injection molds), making it suitable for multi-specification, small-batch trial production and large-scale mass production.
