Introduction
During the operation of the Runqia metal surface hardening plating machine, the working electrode moves toward the workpiece driven by the vibrator. When the gap narrows to a certain distance, the air within the gap is broken down to generate spark discharge. As the electrode continues to approach the workpiece, an instantaneous short-circuit current is produced to further heat the local area. Appropriate pressure between the tool electrode and the workpiece bonds and diffuses the molten materials with each other, forming a fusion infiltration layer and realizing material transfer and surface cladding.
This marks a key difference from conventional electrical discharge machining: in addition to surface texturing, the machine features surface strengthening and hard plating functions, achieving the purpose of comprehensive processing.
The coating thickness formed by the Runqia metal surface hardening plating machine is relatively thin, estimated within 0.10 mm, and thus can only be measured with a microhardness tester.
The Vickers hardness of 45# carbon steel before texturing is only HV 386. After surface texturing and strengthening, its microhardness increases significantly. In particular, when using a tungsten-based cemented carbide electrode, the hardness reaches HV 1300～1900. This can greatly extend the service life of molds. For ordinary workpieces, the mechanical and physical properties of the surface are modified, achieving the technical effect of hard surface with tough core.
Application
Stamping Molds
Common problems in stamping production such as cavity wear, hole enlargement resulting in floating debris (floating strip) and burrs, as well as punch wear and depression, can all be prevented by electric discharge plating with this machine. The service life can be increased by 200%~300%.
Die-casting Molds
Typical defects including erosion and corrosion at the sprue impact surface, and thermal cracking on the mold surface will shorten mold service life and cause product defects. All the above problems can be solved and prevented by electric discharge plating with this machine, extending the service life by 300%~600%.
Forging Molds
Forging molds are prone to surface depressions in service. After electric discharge plating treatment, the surface wear resistance and impact resistance are significantly improved, with the service life prolonged by 200%~300%.
Plastic Injection Molds
A common issue is that sharp corners of the mold wear into rounded corners, especially when using glass fiber reinforced raw materials. Mold wear will cause burrs on molded products, which can be effectively treated by electric discharge plating with this machine.
Cutting Tools
Industrial processing tools require excellent wear resistance. Titanium-plated tools retain only about 20% of their original performance after grinding. By contrast, after electric discharge plating with this machine, the surface tungsten-based cemented carbide layer will not peel off, and re-plating is available. The tool service life can be increased by 300%~500%.
Industrial Machinery
This process is applied to wear-prone parts of mechanical components to extend overall equipment service life, such as textile machinery parts, guide wheels, cams, crushing tools, concrete and tile molds, stainless steel tools, jig parts and more.
Pipe Bending Fixtures
It increases surface hardness and wear resistance, improves clamping anti-slip performance, and extends the service life of fixtures by 3 to 6 times.
Parts & Jigs
It can repair worn dimensions for CNC fixtures and special-purpose machine jigs. Tungsten-based cemented carbide can be deposited on easily worn positions via electric discharge plating, such as collets and tool jigs, raising the service life by 300%~500%.
