Frequently Asked Questions (FAQs)
Frequently Asked Questions (FAQs) about UET Twin Screw Extruders cover core information including product compatibility, performance specifications, installation, operation and maintenance, and after-sales support.
A:A twin screw extruder is a core plastic processing equipment that uses two intermeshing (or counter-rotating) screws within the barrel to work synergistically, enabling material conveying, shearing, mixing, plasticization, and extrusion. Its working principle is as follows: after materials enter the barrel through the feeding system, they are gradually compacted, melted, and uniformly mixed under the combined action of the screw’s rotational thrust and barrel heating, ultimately being extruded into shapes or pelletized through a die. It offers advantages such as high mixing uniformity, stable production capacity, and wide adaptability, making it widely used in fields including plastic modification, masterbatch production, biodegradable material processing, and composite material preparation. It can handle various materials ranging from commodity plastics to specialty engineering plastics.
A:UET twin screw extruders are compatible with a wide range of materials, including commodity plastics (PP/PE), engineering plastics (PA/PC/PBT/PEEK), functional masterbatches (color masterbatches, filler masterbatches, additive masterbatches), biodegradable materials (PLA/PHA), thermoplastic elastomers (TPE/TPR), cable compounding materials, 3D printing filaments, and glass fiber/carbon fiber reinforced modified materials. They meet processing needs across industries such as plastic modification, packaging, electronics, automotive, and medical.
A:It has excellent suitability. Equipped with a precision PID intelligent temperature control system, temperature fluctuations are controlled within ±1°C. Combined with a gentle plasticization process and gradient shear screw design, it effectively prevents degradation or performance damage to temperature-sensitive materials (e.g., PLA, medical-grade polymer materials, heat-sensitive additives), ensuring the stability and functionality of processed materials.
A:UET extruders adopt a dual servo drive system and optimized screw structure design, with energy consumption 15-20% lower than comparable products in the industry. Core components are upgraded via lightweight and high-efficiency transmission technology to achieve high output with low power. For example, the UET-D series consumes only 80-100kWh per ton of material produced on average, significantly reducing production costs with long-term use.
A:Core components (screws, barrels) are made of 38CrMoAlA nitrided steel or bimetallic material; 316L stainless steel is available for medical-grade applications. The surface hardness reaches HRC60 or higher, offering excellent wear resistance. Under normal operating conditions (processing conventional plastics), the service life is 8,000-12,000 hours; when processing highly filled or abrasive materials, the service life is approximately 5,000-8,000 hours (adjusted based on material properties and operating specifications).
A:Routine maintenance is required once per month, including cleaning the equipment, inspecting filters and seals, and refilling lubricants. Core components (screws, barrels, servo motors) require comprehensive inspection and precision calibration every 6-12 months. Wear parts (e.g., filters, gearbox oil seals) are recommended to be replaced every 3-6 months. Proper maintenance extends equipment service life and ensures production stability.
A:Operation is easy and quick to master. The equipment is equipped with a color touchscreen that supports Chinese-English interface switching, with clear and intuitive operating logic. Key parameters (temperature, speed, feeding rate) can be set with one click and monitored in real time. New operators can independently complete startup, production, and basic troubleshooting after half a day of basic training. Remote operation guidance and fault diagnosis functions are also provided to lower operation and maintenance barriers.
A:The entire machine comes with a 1-year warranty, while key functional components (screws, barrels, servo motors, temperature control systems, gearboxes) have an extended 2-year warranty. During the warranty period, free repairs, spare part replacements, and technical support are provided for manufacturing defects and natural component wear—this does not cover failures caused by human error, force majeure, or non-compliant use.
A:Common wear parts (filters, seals, sensors, drive belts) are in full stock and can be shipped within 24 hours of order placement, with delivery to North America taking 3-5 business days. Lead time for core spare parts (screw assemblies, temperature control modules, motor accessories) is 7-15 business days, with expedited order processing available. Spare part pre-storage services are also offered to minimize production downtime risks.
A:Complimentary full-set installation and operational support are offered post-purchase: detailed installation manuals and site planning solutions are included, with engineers providing remote assistance for equipment positioning, wiring, and commissioning. Customized combined online and offline training is tailored to your specific business needs—offline training lasts 1-2 days (covering equipment operation, parameter optimization, routine maintenance, and troubleshooting), while permanent retraining access and one-on-one remote guidance are available online. The training caters to both operators and technical staff, ensuring your team quickly masters the core operational skills of the equipment.
