Application of Various EDM Machine in Automotive Manufacturing

 With the development of the economy and the growth of social demand, there are more and more automotive connector mold parts with complex structures and special process requirements. Along with this, new mold materials with a high melting point, high hardness, high strength, and high toughness continue to emerge, and traditional machining can no longer meet the requirements.

 

Direct use of electrical energy, electrochemical energy, sound energy, etc., up to now, there have been a series of advanced equipment, which is widely used in various departments of automotive connector mold parts processing and customization. The EDM automotive connector mold parts is essentially different from mechanical processing. It does not require the tool material to be harder than the workpiece material, nor does it require significant mechanical force during the processing process, but directly uses electrical energy, chemical energy, and light. It can process the workpiece with sound energy to meet certain shape, size, and surface roughness requirements.

 

The EDM machine meaning is like electrical discharge machining or electro-erosion machining. It includes EDM forming, wire EDM, EDM inner hole, outer circle and forming grinding, EDM synchronous rotary machining, EDM surface strengthening, and lettering, etc. Process method. Commonly used in the processing and customization of automotive connector mold parts are EDM and CNC wire EDM. At present, it is an important processing method for the surface of automotive connector mold parts. EDM machining refers to a process method to process the workpiece in a certain medium through the electro-corrosion effect of the pulse discharge between the tool electrode and the workpiece electrode. It can process a variety of materials with a high melting point, high hardness, high strength, high purity, and high toughness, and shows many advantages in production, so it is rapidly developed and widely used, to practice CNC die sinking and EDM fast hole drilling for instance. It is used for the processing of holes and cavities in the processing and customization of automotive connector mold parts of automotive EDM machine.

Bumper

 

The front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but more importantly, have the functions of absorbing and mitigating external impact, protecting the body, and protecting the body and occupants. It can play a buffering role in the event of a low-speed collision. The front and rear car bodies can play a certain role in protecting pedestrians in the event of an accident with pedestrians. The front and rear bumpers of the car are converted from the precious metal materials to the current plastic materials, such as polyester, polypropylene, polycarbonate, etc., and are infiltrated into alloy components. They are made by injection molding, in addition to maintaining the original protection, in addition to functions, it can also achieve harmony and unity with the car body shape, making the car body more lightweight. The processed bumper not only has high strength and rigidity, but also has the advantage of being weldable, and has good coating performance.

Dashboard

 

The instrument panel is located directly in front of the driver, and it is generally equipped with a driving odometer, a speedometer, an engine tachometer, a fuel gauge, and a warning light. The instrument panel is divided into the non-airbag instrument panel and airbag instrument panel (more secure) according to safety and divided into the rigid plastic instrument panel, blister instrument panel, and semi-rigid foam soft instrument panel according to comfort. The hard-plastic instrument panel is made by the injection molding process, with a simple process, low investment, and wide application. Part or all of it is painted with decorative paint or soft-touch paint to improve appearance, color tone, or texture. The blister instrument panel is adsorbed and bonded outside the injection molding or pressing frame, or compounded with the skin during injection molding so that its appearance is cortical. The semi-rigid foam soft instrument panel is filled with polyurethane foam between the skin and the frame, which not only improves the touch but also increases the ability to absorb energy. At present, the skins of semi-rigid foam soft instrument panels mainly include vacuum thermoformed skins and slush-molded skins. The former is made by traditional artificial skin technology, and the latter is characterized by uniform patterns, no internal stress, wide design, and high tolerance. widely used.
