Explore our premium automated configurations optimized for robust industrial surface engineering in Manila, Batangas, and the Calabarzon region.
As the economic core of the Philippines, the Metropolitan Manila area—together with nearby industrial hubs in Calabarzon and Central Luzon—drives the country's manufacturing, shipping, construction, and power generation sectors. However, operations in these tropical regions are constantly threatened by intense physical challenges: heavy mechanical abrasion, corrosive marine atmospheres near Manila Port and Batangas Bay, and high-temperature erosion in processing plants. Traditional manual welding and thermal spraying often fall short when long-term component lifecycle extension is needed.
Plasma Transferred Arc (PTA) Welding has emerged as the premier technology to combat these harsh wear environments. By utilizing a highly concentrated plasma arc to melt both the base metal's surface layer and a metered stream of metallic alloy powder, PTA cladding achieves a true metallurgically bonded coating. Unlike mechanical bonding methods, the PTA process limits the dilution rate to less than 5%. This low dilution rate preserves the exact chemical properties of high-hardness alloys—such as Cobalt-based Stellite, Nickel-based alloys, and Tungsten Carbide composite matrixes—directly onto standard carbon or low-alloy steel components.
Achieves true fusion bonding with substrate steels, ensuring zero flaking under extreme cyclic stress.
Keeps base metal dilution under 5%, preserving the full hardness and wear properties of overlay alloys.
Adapts to specific requirements via feeds of tungsten carbides, stellite cobalt, or iron-chromium alloys.
Seamlessly integrates PLC control and multi-axis manipulators for consistent weld profiles.
Our cladding and surfacing technologies have penetrated critical industrial and engineering sectors globally. In the local Philippine market, these are applied to targeted, high-demand processes:
Known as the "Rice Granary of the Philippines," Central Luzon relies heavily on agricultural harvesting and milling machinery. Sugarcane and rice processing mills require high-capacity screw conveyors, extrusion screws, and cutter blades. By utilizing systems like the DYY-LC501 Hydraulic Rod Automatic Cladding Machine, agricultural operators can apply a cobalt-base hardfacing layer to extend screw lifetime by up to 5 times, reducing harvest season downtime.
Manila’s major maritime shipping lanes and Batangas' oil terminals face severe salinity and cavitation. Standard valve seats degrade rapidly under corrosive conditions. Utilizing our valve-specific systems (such as the FB-200P Automatic Valve Plasma Surfacing Machine), valve surfaces are clad with corrosion-resistant cobalt alloys, ensuring leak-free performance and compliance with API international standards.
For mining operations and public works projects throughout the archipelago, wear components like cutting picks, drill bits, and excavator buckets face continuous impact and friction. The DJC-LC305 Automatic Cutting Picks Plasma Cladding Equipment deposits a dense layer of tungsten carbide particles embedded in a tough nickel-based alloy matrix. This layer withstands intense geologic friction, keeping extraction equipment operational for longer periods.
High-temperature forging dies, guide rollers, and extrusion pins in metallurgical mills are subjected to severe thermal fatigue. Our planar surfacing systems (like the DNC2000) provide protective, heat-resistant overlays, preventing early thermal cracking and reducing raw steel wear costs.
Precision is vital in military and aerospace applications. Turbine blades and high-precision shafts must be restored to original dimensions without altering the properties of their underlying base alloys. Our advanced CNC laser cladding units and specialized PTA systems allow for precise overlay thickness, restoring structural integrity with minimal heat-affected zones.
