Vietnam Rotec Co., Ltd products

The 4 Column Hydraulic Press Machine by Rotec Vietnam is engineered to serve critical roles in various industrial applications, such as the manufacturing of electronic components and metallurgical processes. This machine is ideal for shaping, assembling, and dismantling machine parts. It employs hydraulic transmission to create different product shapes with high structural integrity and ease of operation. The press can generate up to 400 tons of force, with table dimensions reaching up to 1200x1200 mm, making it versatile for diverse material sizes. The machine features an automatic operation cycle where, upon placing the material on the table, it initiates the pressing process and stops once the predefined pressure is attained. Safety mechanisms include overload protection to safeguard the motor, pump, and hydraulic cylinder. The press is equipped with PLC control and anti-shock features to enhance operational safety. Its large oil pipelines reduce pressure loss and improve seal longevity, leading to high productivity and cost-efficiency over extended use. The hydraulic press is especially suitable for industries requiring large-scale or detailed component pressing, promising significant labor savings and elevated productivity.

The Apron Type Shot Blasting Machine from Rotec is extensively used in Vietnam for achieving thorough cleaning of materials that cannot be effectively cleaned through manual methods. This machine, designed with professional manufacturing technologies, caters to the aesthetic and functional needs of various enterprises. The primary component responsible for the effectiveness of this system is the steel shot blaster head cluster, which determines productivity and cleaning quality by propelling steel shots at speeds between 70 and 80m/s. Additionally, the machine consists of a conveyor belt workpiece feeder, various shot transportation clusters, bucket elevator, blasting chamber, separator and dust collector unit, and a control cabinet. The blasting operation is driven by a centrifugal shooting head equipped with vanes and shot cups, ensuring high-speed projection of steel shots (up to 80mm/s) that impact and meticulously clean the surface of the workpiece. Any dust generated during the process is captured and retained by a dust collection system to maintain a clean environment. This equipment is ideally suited for cleaning cast, forged, and small components, delivering high efficiency and reduced long-term costs.

The Automatic Hydraulic Baler Machine operates based on the principle of generating enormous compressive force using hydraulic pressure. Designed following Pascal's Law, when pressure is applied to a confined liquid, it remains constant throughout the system. This machine is equipped with two distinct hydraulic cylinders connected by piping, each cylinder containing a perfectly fitting piston. One piston acts as a pump with modest mechanical force, while the larger piston exerts high force over a larger area. The machine's pressing table, located between the upper and lower platen, receives feedstock which is compressed by the main hydraulic cylinder to the desired size. Post-compression, a sliding mechanism ejects the compacted material, preparing it for the next batch. Key features include a hydraulic power unit tailored to specific materials and bale sizes with a system of safety, non-return, and flow control valves sourced from G7 countries. The hydraulic cylinders, made from alloy steel for wear resistance and high hardness, ensure no oil leakage and withstand high temperatures. The main frame and movable platen, made from SS400 steel, ensure robust construction with slots to thread baling wire, facilitating tight and uniform bales. An automatic baling system ties the bales, optimizing large-scale operations. A sturdy feed door, also made from SS400 steel, provides a clear view for operators to ensure uniform material spread for efficient compression. The control cabinet features imported electronic components with multiple safety levels, ensuring consistent operation, motor protection, and automatic reverse to prevent jamming and overloading. This machine is well-suited for high-volume recycling operations in materials like textiles, paper, and waste, reducing labor and production costs.

The Automatic Vacuum Recovery and Shot Blasting System is designed using modern European technology to address limitations in conventional shot blasting systems. This advanced system includes various components like a vacuum suction system, dust cyclone unit, shot supplying system, drying drum, secondary shot separation and dust collection system, and multiple shot blasting units. The system ensures efficient cleaning and surface treatment of large metal structures like ship blocks or wind tower modules by utilizing high-speed steel shots driven by compressed air. As the shots impact the surface, they remove contaminants and rust, which are then separated and filtered, allowing the clean shots to be reused in the system. The process ensures a dust-free environment by capturing and filtering dust generated during blasting. Offering significant advantages, this automated system reduces maintenance needs by eliminating mechanical wear and potential technical issues, making it suitable for industrial applications needing consistent and high-quality surface treatment.

Rotec's Belt Press Machine is designed to efficiently handle sludge treatment across various industries. This equipment transforms sludge into thin, firm, and fast-drying sheets, enabling effective water separation. Developed by a consortium of experts from prestigious technical institutes, the machine has undergone more than a decade of research and testing. It is suitable for applications in food processing, dyeing, tanning, plating, mining, and ore processing, as well as urban and industrial wastewater treatment. The machine operates continuously and economically, making it ideal for large-scale operations. It utilizes a dual-conveyor system for filter pressing and incorporates a process that adjusts pressure to retain and remove sludge effectively. The final cake-like sludge has a moisture content between 60-85%. The system includes a sludge pump, flocculation tank, belt system, dry sludge storage, and clean water pumps, providing a comprehensive solution. Rotec offers a 12-month warranty and technical support to ensure operational efficiency.
