Rubber sealing profile design

State aviation special rubber sealing profiles most advanced enterprise has successfully promoted the application of CAD / CATIA and other design software .
New designed sealing profiles more attention to functional requirements , from the previous sponge rubber sealing profiles , solid rubber sealing profiles to the composite rubber seal change , involving a variety of rubber composite sealing profiles, metal frame with a variety of rubber and rubber and composite sealing profiles plastic composite sealing profiles. In some of the newer models design, or even a variable cross-section structure of composite rubber sealing profiles , functional composite rubber sealing profiles new structure.
By PROE / CATIA , etc. The introduction of product design parameters can be entered directly into the CNC machining center for mold design and machining profiles .
Molding profiles
Airlines with special rubber sealing profiles molding materials are widely used , complex structure, forming several challenges and difficulties .
Airlines with special rubber sealing profiles using materials include foam material, pure rubber material, composite rubber materials, metal rubber composite , a variety of composite materials and so on. The difference in shrinkage characteristics of different materials , the interface between the binding force , such as compatibility problems of the molding material is more difficult.
From aviation to use special rubber pull tight plastic seals profiles environment, tend to design a profile section and the overall size of a large span . Small cross-section of 1mm cap sealing profiles , shaped like a large cargo door gate sealing profiles can often reach more than 10 m ; sections as simple as sealing strip profiles, such as variable cross-section of complex sealing profiles .
In order to produce the structure of variable cross-section rubber seal profiles, with enterprises to introduce European patent molding technology and equipment. The principle is mainly for cutting feed side and end to the computer through a metal skeleton common input signal , the output signal is controlled by the computer at the die cylinder moves , its movement toward Multijaw die for variable cross-section of the sealing strip extrusion . Simple variable cross-section can also be used with other automated or mechanical means control methods to control mold or cutting tool Multijaw actions to complete variable cross-section profile extrusion molding.
From the air with special rubber sealing  seal cable profiles designed structural point of view , many profiles are fully closed hollow structure, and there are fabric composite material or metal matrix material, forming very difficult. There are enterprises through the use of patented molding technology, fully closed structure of the hollow outer fabric to achieve the overall parcel fabric, fabric without joints and lap joints , sealing profiles smooth surface, size consistency .
