Empowering local engineering systems in Alajuela, San José, and Cartago with state-of-the-art additive manufacturing controllers and wear-resistant overlay technology.
Costa Rica has rapidly transitioned from a traditional agrarian economy to a sophisticated, high-tech industrial hub. With the explosive growth of the medical device manufacturing industry in the Free Trade Zones (FTZs) such as Alajuela and Heredia, alongside heavy investments in renewable energy, maritime transport, and mechanized agriculture, the wear and tear on precision tools and heavy machinery parts has become a major operational challenge.
Extending the lifespan of high-precision stainless steel and nickel-alloy molds utilized in medical device extrusion and micro-injection molding operations.
Protecting geothermal turbines, steam valves, and hydroelectric runners in the ICE (Instituto Costarricense de Electricidad) grid against harsh cavitation and corrosion.
Enhancing the durability of harvesting blades, sugar mill shredder teeth, and heavy agricultural equipment components operating in abrasive soils.
Corrosion protection for structural elements, container cranes, and marine vessel shafts operating out of Puerto Caldera and Moín Port.
By introducing high-end automated laser cladding and Plasma Transferred Arc (PTA) welding setups to Costa Rican industrial clients, manufacturers can significantly reduce import reliance, eliminate long lead times for spare parts, and minimize costly downtime.
Consult with Our Engineering TeamChoosing the right metallurgical bond technology: PTA vs. Laser Cladding systems.
Utilizing a focused laser beam, this method melts a precise volume of the substrate surface together with a metallic powder feeder. This achieves an extremely small Heat-Affected Zone (HAZ), reducing structural distortion to near-zero levels. This is ideal for precision parts like hydraulic shafts, rotor bearings, and medical grade tooling.
A cost-effective, high-throughput solution for heavy wear industries. By using a plasma arc to fuse alloy powders (like Stellite or Tungsten Carbide) with the base material, it provides a high-density, metallurgically bonded protective coating ideal for extreme corrosion environments.
At present, our products and systems have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy, and electric power.
