Understanding Warm Isostatic Press (WIP)

Kin-Tech Autoclave's WIP Series

Warm isostatic pressing (WIP) is a variant of cold isostatic pressing (CIP) that includes a heating element. It employs warm water or a similar medium to apply uniform pressure to powdered products from all directions.

WIP is a cutting-edge technology that enables isostatic pressing at a temperature that does not exceed the boiling point of the liquid medium. This process involves utilizing flexible materials as a jacket mold and hydraulic pressure as a pressure medium to shape and press the powder material.

The WIP process typically involves heating the liquid medium first and then continuously injecting the heated liquid medium into a sealed pressing cylinder through a booster source. To ensure the accuracy of temperature control, the pressing cylinder is equipped with a heating element.

Concept of Lamination

Definition

Lamination is a process of permanently joining two or more layers of material together. It is commonly done by applying heat, pressure, or adhesives. The result is a composite material that possesses improved qualities such as appearance, strength, durability, and stability.

Method of assembly

A lamination press is typically used to carry out the lamination process. This hydraulic compression press applies pressure to the layers of material, bonding them together. The press may have multiple openings with precise temperature and pressure controls. The platens, or pressing surfaces, can be heated using electric heaters, steam, or hot oil. In some cases, the platens are internally cooled for faster processing. Specialized vacuum lamination presses have been developed for specific industries such as electronic materials, printed circuit boards, decorative laminates, and honeycomb panels.

Computer and process control systems are often integrated into more complex laminating systems. These systems may include automated loading and unloading systems, staging racks, and turnkey installation.

Applications in electronic components

Lamination plays a crucial role in the production of electronic components and displays. Thin film deposition techniques are used to create various materials used in electronic manufacturing, such as semiconductors, metal conductor films, and microelectronic integrated circuits. Lamination is also used in the fabrication of electronic displays, which require conductive and transparent films, luminescent or fluorescent films, as well as dielectric and insulating layers.

Thin film equipment and lamination processes find applications in semiconductor manufacturing, flat panel display manufacturing, optical coatings, magnetic storage, medical equipment, research, and surface analysis. The materials processed by thin film equipment include metals, dielectrics, ceramics, aluminum, silicon, diamond-like carbon (DLC), dopants, germanium, silicides, compound semiconductors (GaAs), nitrides TiN, tungsten, and other refractory metals.

Conclusion

Lamination is a versatile process that enables the production of composite materials with improved qualities. It is widely used in various industries, particularly in electronic component manufacturing and display fabrication. The control of temperature, pressure, and speed during lamination is essential to achieve high-quality results. Lamination presses with advanced features and automated systems have been developed to meet the specific requirements of different applications.
