The Highlight of Shuntec Pressurized Air Bulge Forming Press

Nowadays, the product appearance of electronics and automobiles is getting more and more beautiful and complex. Take the mobile phone as an example, the back cover of the mobile phone is gorgeous with new multilayers printing processes. And the complex R angle is the popular and common design for the mobile phone back cover. So, it is important to quickly form the sheet/film with a complex shape before IMD forming process.

Shuntec's pressurized air bulge forming press is newly designed and developed for composite sheet/film hot forming. And it is becoming increasingly popular among manufacturers because of its ability to produce seamless, lightweight, "near-net-shape" parts. During the pressurized air bulge forming process, operators insert a blank into a mold. The special heating device of the press quickly heats the blank to its softening temperature, with optional maximum heating temperature ranges from 600 ℃ to 1000 ℃. Then, the press introduces pressurized air into the chamber. The pressurized air presses from top to bottom with the segmented high pressure, while the lower mold cavity is evacuated. The pressurized air forms the material to the shape and contour of the tool so that the film material is perfectly and accurately formed and molded into a complex shape.

Throughout this process the press acts as a clamp, applying force to the tool in order to counter the pressure being injected into the chamber, ensuring the tool remains closed. The air pressure and holding time can be adjusted separately. There is no upper mold, only a lower mold. There will be no problem with film surface scratches caused by direct contact with the mold on the film surface. The residual stress of the formed film is at a very low level. The corners of the composite material do not turn white after forming, while the printed layers are continuously layered, and do not separate.
