High-performance plasma welding systems optimized for the Central American high-tech manufacturing corridor.
Costa Rica has transitioned from an agrarian economy to a sophisticated hub for Medical Device Manufacturing and Aerospace Engineering. With the rise of the Coyol Free Zone and various technology parks in Alajuela and Heredia, the demand for high-precision metal joining and surfacing technologies has skyrocketed.
As a leading Plasma Power Supply Factory, Shanghai Duomu recognizes that Costa Rican industries require more than just hardware. They require Information Gain—the specific technical knowledge that allows them to reduce component wear, minimize downtime in sugar refineries (Ingenios), and enhance the longevity of medical molds.
In an era of global volatility, Shanghai Duomu ensures a stable supply of Plasma Transferred Arc (PTA) systems to San José. Our digitized inventory and rapid manufacturing cycles guarantee that Costa Rican factories never face production halts.
Our "Factory 4.0" approach integrates IoT monitoring into our plasma power supplies, allowing for remote diagnostics and predictive maintenance—a vital feature for offshore partners in Central America.
We streamline the procurement process with localized documentation, compliance with international standards (CE/ISO), and optimized logistics routes from Shanghai to Puerto Limón and Caldera.
From aerospace military industry to agricultural machinery in Guanacaste.
Protecting harvesters and screw conveyors from abrasive volcanic soil.
High-precision cladding for turbine components and landing gear.
Anti-corrosive surfacing for valve seats and drill stabilizers.
Thermal barrier coatings and wear-resistant layers for heavy casting.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machine and Laser cladding machine for more than ten years with a strong technical background. Our independent R&D team develops, produces and sells plasma cladding machine equipment designed for stability and efficient long-term operation.
In addition, our laser cladding equipment effectively supports large-scale remanufacturing projects. We have mature technological means to provide complete sets of industrial equipment solutions, especially for the high-demand sectors in Costa Rica's Free Trade Zones.
Learn More About Our ExpertiseIn the Plasma Transferred Arc (PTA) process, the power supply is the heart of the operation. For companies in Limón or Puntarenas operating in high-humidity environments, our power supplies are engineered with superior insulation and cooling systems. The dilution rate—the mixing of the base metal with the alloy powder—is kept below 5% in our DML-V03 series, ensuring the surface properties of the alloy are fully realized.
When a choke valve fails in an oil rig or a mud pump valve seat wears down, the cost isn't the part—it's the lost production time. PTA surfacing creates a metallurgical bond that far exceeds traditional thermal sprays.
In Costa Rica’s biomass energy sector, screw conveyors face extreme erosion. Hardfacing these parts rather than replacing them reduces carbon footprint and material costs significantly.
Our integrated robots (DH1440-B06) provide repeatability that manual welding cannot match, essential for the strict quality controls of the medical device industry.

Most standard plasma power supplies and PTA machines have a manufacturing lead time of 15-30 days. Shipping from Shanghai to the port of Caldera typically takes another 25-35 days, ensuring your facility is operational within two months of order placement.
Yes, all our equipment is custom-configurable to meet international power standards, including the 208V-480V / 60Hz requirements common in Costa Rican industrial zones.
While PTA is primarily used for larger industrial components, our high-precision DML-V03 series is frequently used to maintain and repair the heavy-duty molds used in medical plastics injection—critical for the San José med-tech cluster.
We provide comprehensive digital support, including remote video training, detailed English manuals, and 24-hour diagnostic responses. For large-scale installations, on-site commissioning is available.
