Introduction Slitting machines are key equipment in paper and packaging plants. They cut wide rolls of paper or film into many narrow strips. Keeping the material tension steady is very important. It makes sure the cuts are clean and the widths are exact. Old slitting machines often use magnetic particle clutches to control tension. These clutches work well for small tensions at slow speeds. But they cause problems at high speeds. The friction creates a lot of heat. This heat shortens the clutch life and limits how fast the machine can run. Challenges in the Pressroom Running these machines in a busy printing factory is hard. There are several problems: Sudden Load Changes: Starting, stopping, and changing rolls puts big, instant stress on the motor. Many drives can't handle this shock. They stop working. Tough Environment: The air is full of dust. Temperatures get hot. These conditions are hard on electrical parts. Need for Precision Control: Sometimes three motors work together on one machine. They must run at exactly the right speeds. If they don't, the cut material won't be straight or the same width. How V&T Drives Help V&T drives solve these pressroom problems effectively: They Handle Heavy Shocks: V&T drives manage the big load spikes during start, stop, and roll changes. They keep the machine running. Other drives often trip and cause shutdowns. They Work in Tough Conditions: V&T drives are sealed against dust. Their cooling works well, even when it's hot. We know this works. These drives have run reliably in printing factories for 12 years. Dust and heat haven't caused major breakdowns. They Control Speed Precisely: V&T drives control motor speed and power very accurately. When multiple motors need to work together smoothly, these drives make it happen. This keeps the material tension steady. The result? Material is cut cleanly and evenly, every time. The Benefits Using V&T drives on slitters fixes issues with older clutch systems, especially at higher speeds and with sudden loads. They also handle the difficult pressroom environment well. Customers get important advantages: More Machine Uptime: Fewer stops from load shocks or environment problems mean the machine runs longer. Better Quality Cuts: Precise speed and tension control ensure accurate sizes and clean edges. Built for the Job: These drives handle common pressroom dust and heat, lasting longer. Potential for Faster Speeds: They provide the stable power needed to try running slitters faster than older clutches allowed.

Their real-world performance is proven. For 12 years in actual pressrooms, they've been reliable. V&T drives are a solid choice. They help customers get more from their slitting machines.

Today, clean air and efficient operation matter more than ever. V&T proudly introduces our advanced Oil-Free Scroll Air Compressor. This innovative machine is made for places where air quality is critical. It's the perfect power source for labs, healthc What is an Oil-Free Scroll Air Compressor? This compressor is a big step forward in air technology. Unlike old piston compressors, it doesn't need oil for lubrication. It uses a special scroll movement to squeeze the air. This guarantees the air coming out is completely oil-free. You get cleaner air, less maintenance, and no risk of oil contamination. It gives you peace of mind. How It Works: The Smart Heart of the Machine The orbiting scroll rotates in the order shown in Figure 1-2-3-4. The crescent-shaped compression chamber gradually decreases in volume, compressing the gas inside. The compressed gas is then discharged from the center of the fixed scroll. Two precise spiral scrolls work together: Fixed Scroll: This part stays still. It forms the main compression chamber. Moving Scroll: A motor drives this part. It orbits in a tight circle around the fixed scroll. Air gets pulled in. It gets trapped between these two scrolls. The moving scroll squeezes the air pockets smaller and smaller. Pressure builds steadily. Finally, clean, compressed air pushes out through the center. The scrolls never touch metal-to-metal. So, it needs no oil at all. This stops oil from ever getting into your air. Why Choose Our Oil-Free Scroll Compressor? Perfectly Clean Air: Meets the strict ISO 8573-1 Class 0 standard for oil-free air. This means absolutely no oil, mist, or vapor in your air supply. Gives you zero-risk air for critical jobs: precision labs, sterile drug making, safe food production, and high-end electronics. Super Quiet Operation: The unique scroll design doesn't need parts to touch, so it runs much quieter. It works smoothly and quietly. Fits right into noise-sensitive places like labs, hospital rooms, cleanrooms, or offices. Makes the workspace better. Great Energy Savings: Squeezes air in one smooth, continuous motion. This wastes less energy. Uses less power than old piston compressors. Saves you significant money on electricity bills over time. Good for your budget and the planet. Compact Size, Saves Space: Built in a smart, modular way. It's small and simple. Fits easily under lab benches, in tight equipment corners, or other small spots. Makes the best use of your valuable space. Built to Last, Easy to Care For: The oil-free design means fewer parts can break. It runs reliably for a long time. Maintenance is very simple. Mainly, just change the air filter regularly. Saves you time and money on upkeep.

XCMG Heavy Duty's electric mining dump trucks are now running in mines in Southwest China. These trucks use V&T's special motor controller. The order is worth about 16 million yuan. Mine operators chose these trucks because they handle tough jobs well and meet special needs. This is a big step towards cleaner "green mines". These electric trucks are as strong as XCMG's older fuel-powered ones. They have a tough cargo box, strong frame parts, and a solid body. They carry very heavy loads well. The V&T controller helps the transmission learn by itself. It learns during gear changes and when the truck powers down. This fixes problems caused by wear over time. Shifting gears becomes smooth and exact. The truck works reliably in many situations – flat ground, hills, or water. You don't need to keep resetting its software. Driving is comfortable too, with adjustable seats, strong springs, and a cab designed for a good view. Being electric, these trucks are cleaner, quieter, and save energy. Their special motor braking system captures energy when slowing down. It saves over 10% of the energy this way. The whole system runs very efficiently, over 80% of the time. The V&T controller makes everything work together better – the motor, the gearbox, and the battery. This smart teamwork means the truck uses at least 5% less power than similar trucks. On regular mine routes, it learns from data about how the truck moves. Then it figures out the best times to shift gears and how to use energy, saving even more power. Many electric vehicles struggle with how far they can go and how strong they are. XCMG's electric mining truck handles this well. It uses safe and powerful lithium iron phosphate batteries. These batteries hold nearly 200 kilowatt-hours of power. Clever control helps the truck go further on a charge. It starts with huge force – up to 18,000 Newton-meters of torque. It can go from 0 to 50 km/h in under 20 seconds. The truck uses a tough 7-speed gearbox, proven on 100-ton trucks. This gearbox runs cool, works well, and is simple. The V&T controller automatically picks the right gear for the hill slope and the truck's weight. This keeps the pulling power strong. The truck can climb very steep slopes, over 45%. Even fully loaded, it climbs slopes steeper than 30%. This means it easily handles rough mine terrain.

Foshan, Guangdong recently received a group of new eco-friendly buses. Two hundred brand-new hydrogen fuel buses have been delivered. They will soon run on roads across the Greater Bay Area. These buses use electric motor controllers from Shenzhen V&T Technologies Co., Ltd. (called V&T here). When these buses start operating, they will cut down harmful particles (called PM2.5) in bus exhaust. This helps keep the air fresh in the Greater Bay Area cities. V&T is an important maker of motor controllers for new energy vehicles. They worked closely on this hydrogen bus project. V&T supplied key motor control systems for the buses. This makes sure the buses’ power source works well and reliably. V&T showed strong technical skills. They also delivered parts fast enough to keep up with the bus maker’s production. The bus maker praised V&T for this good work. Right now, all 200 hydrogen buses have their license plates. This means they can soon begin carrying passengers between cities in the Greater Bay Area. Adding these zero-emission buses does more than just update public transport. It’s a solid step toward cleaner air. These buses will truly help reduce PM2.5 levels in our air. They’ll make the air cleaner for cities to "breathe." They’ll help protect the environment we all share.

Recently, a fleet of 18-meter-long pure electric BRT buses equipped with V&T electric vehicle motor controllers has been put into large-scale operation on the main roads of a coastal city. These giants not only practice green and low-carbon concepts through zero emissions but also significantly enhance urban public transport capacity with their efficient and safe operations, effectively alleviating passenger flow pressure during peak hours, becoming an eye-catching new scene on the streets. As urban areas continue to expand, road traffic pressures are increasing day by day. Apart from rail transit, developing Bus Rapid Transit (BRT) systems is becoming an increasingly popular choice for many cities and even an important symbol of modern urban construction. So, what is BRT? BRT, or Bus Rapid Transit, is a new type of high-capacity public transportation method that integrates modern bus technology and intelligent traffic management. It features dedicated roads and modern stations, offering high operational efficiency, often referred to as "metro on the ground." The aim of BRT is to provide convenient passenger services comparable to those of rail transit. The application of this system plays a significant role in improving the efficiency of bus operations and alleviating urban peak hour congestion. Industry observers point out that with more cities promoting the electrification and efficiency of buses, vehicles using V&T electric control solutions are expected to appear in more cities in the future. They will undertake the heavy responsibility of citizens' daily commutes, contributing to the upgrade and image enhancement of the urban transportation network.
