At Dujua, we are always committed to delivering solutions that combine performance, durability, and efficiency to meet our customers’ challenges. One example of this approach is the use of hard MIG welding, a variation of conventional MIG welding that provides highly wear-resistant coatings on critical surfaces of industrial parts and equipment.

Hard MIG welding is widely used to apply a protective layer of specially formulated material onto components that operate under severe conditions of friction, abrasion, and impact. This coating layer results in a substantial increase in the service life of parts, reducing the frequency of replacements and, consequently, the operational costs related to machinery maintenance.

Among the main benefits provided by this technique are:

• Greater resistance to abrasive wear and impact in demanding industrial environments.

• Reduction of unplanned downtime and maintenance costs due to the extended durability of coated parts.

• Improved operational reliability, contributing to more continuous and efficient production processes.

This solution is especially suitable for components subject to intense wear—such as machine parts, tools, and metal structures—that require superior performance in both routine operations and more demanding applications. By applying hard MIG welding in accordance with the most rigorous technical standards, Dujua delivers robustness and reliability, reflecting its commitment to quality, safety, and the longevity of the industrial solutions it provides.

Dujua has successfully completed the startup of the expansion of Inpasa’s plant in Balsas – MA, reinforcing its commitment to deadlines, quality, and excellence in the execution of industrial projects. The delivery was carried out according to the established schedule, as a result of the integrated work between engineering, fabrication, assembly, and commissioning.

The project involved the installation of a second boiler, a technically sensitive intervention that required a high level of precision, planning, and care at every stage. With the completion of the startup, Inpasa now benefits from increased production capacity, greater operational reliability, and optimized industrial processes.

Among the equipment supplied and installed by Dujua in this project are belt conveyors, drag conveyors (redlers), a surge silo, as well as platforms, walkways, and structural support towers. The entire system was developed and executed in compliance with technical specification and safety standards, following Dujua’s quality, robustness, and reliability benchmarks.

Dujua expands its portfolio of industrial solutions with the launch of the automatic lubrication system, developed to meet the demands of operations that require high performance, reliability, and reduced maintenance costs. The solution reflects Dujua’s technical expertise applied to the development of systems that go beyond simple lubrication, directly impacting equipment efficiency and availability.

Although the primary function of lubricants is to reduce friction between mechanical components, correct, precise, and scheduled application is essential to ensure continuous machine performance. Dujua’s automatic lubrication system, also known as centralized lubrication, transports and delivers lubricant directly to application points using programmable controllers, pumps, and distributors, ensuring ideal dosing at the correct intervals.

This technology significantly reduces mechanical failures and premature wear of parts and bearings, delivering real gains in productivity. Key benefits of the Dujua solution include labor savings, reduced unplanned downtime, extended equipment service life, and lower operator exposure to accident risks during manual interventions.

It is an investment with rapid payback that contributes to optimizing production processes and reducing operational costs over time. With this launch, Dujua reinforces its commitment to developing robust, safe, and efficient industrial solutions aligned with the real needs of its customers and the highest quality standards in the market.
