Nonlinear analysis and optimization design of seal structure;

Study on contact characteristics between seal and door based on direct restriction;

Numerical Simulation of Seal Extrusion;

Design technique of deformed sealing strip mould;

The control system design of the diecutting machine for sealing strip manufacturing is presented with the analysis of the manufacturing requirement and the structure of machine.

Impact modifier ABS and PVC resin were modified by blend, and the proportion of the PVC hard granular material used for sealing strip was discussed, its physical mechanical performance approached to import particle material and the processing was simple.

Extrusion mold design to PVC/NBR-26 seal strip for construction;

The research of new brand EPDM for seal strip

The Application for PVC Thermoplastic Elasticity Material in Automobile Sealant;

For decreasing the leakage and improving the efficiency of the cavity,the self-lubricative seal element is installed in scroll tooth.

In allusion to work trait of oil-free scroll compressor,add seal element which is made of lubricative material to the scroll teeth and the tangent plane between bracket and whisht scroll in order to realize oil-free technique for scroll compressor successfully.

The installation of self-lubricative seal element of scroll tooth is a key technique for oil-free scroll compressor.
