A procedure that uses a polyamide or polyolefin material was introduced to defend and encapsulate a cathode piece including a circuit board from different environmental points. Their goal was to safeguard these elements from dust, moisture, dirt, and vibration. Shaping garments, sealing a connector, and straining reliefs are their primary offers.

Elements such a specialized shaping device and raw materials are the key point of this method. These low pressure molding processes make use of dimer acid and polyamide based materials to mold compounds. This method is considered as the innovative manufacturing procedure which incorporates the injection of potting and molding wherein the hot melt adhesives are injected at low pressures.

This form of application is an inexpensive substitute for epoxy setting that ensures they protect the numerous delicate pieces. Their application in connector or cable moldings can effectively tension reliefs compared to the traditional plastic injections. They have the capability to offer accomplished seals for the elements which ensure tight water encapsulation, and to effectively strain reliefs.

Their low viscosity is responsible for injections at low pressures wherein the wires and pieces are not harmed or dislocated. They can easily encapsulate fragile elements which protects them from hazardous fumes created by the materials or their processing. The customary process would incorporate the steps of molding the case followed by palletizing them.

The electric elements are inserted, and then afterwards are preheated. Once they have been preheated, encapsulating, settling them in, and vacuuming those components are the next steps, and followed by the last steps which are inspecting and curing. The flow of the low pressure process starts with the insertion of pieces, and is shaped before they are tested.

The complete idea affiliated with a shaping method states that are qualified to replace a housing and potting process in a single application. This procedure tells you that you should a large PC board with the utilization of an external connector before you place them in a case. The individual encapsulation method of a component is to be performed before the conventional ones.

Over molding various figures is also advised which is followed by the packaging of sensitive and high performance elements. Shaping grommets and tension reliefs, sealing multi wire connectors, and shaping them with strain relief are the primary steps of attaining excellent strain relief. Furthermore, they are followed by the procedure which involves sealing of micro switches.

This process was constructed by Henkel Corporation with its base in Europe, and an experiment about the utilization of a hot melt material which is important in creating a strain relief and sealing a connector was performed. It was the automotive business which was accountable for their commercial introduction. Their focus was pointed to lighter and safer components that replaced a cumbersome and toxic procedure.

After their introduction, they were commonly used in numerous fields that include industrial, military, medical, consumer items, wire harness, and other outputs that are to be sealed and protected from the environment. Similarly, they are also applied in numerous goods that include USB thumb drive, control boards, RFID tags, and moisture sensors. Clearly, if the procedure that focuses on sealing and protecting the components are to be applied, this process is labeled as the finest course of action.
