Research And Development
CAD/Pro-E computer design system uses FEA finite element analysis and other three-dimensional software to assist design.
● Perfect design and experimental standards
● Advanced Product Design Ideas from Japan and Germany
● Special Rubber Material for Various Requirements
● Experimental test capability and perfect trial production system
● High Precision Die Manufacturing Ability
The main factors considered in product design are:
● Geometric structure - excellent sealing and dust-proof effect
● Rubber Material - Excellent Physical and Chemical Properties, Excellent Wear Resistance, Excellent resistance to high and low temperature.
● Optimum Design--Rational Matching of Geometric Structure and Rubber Material
We choose suitable rubber according to the use temperature and sealing medium of the oil seal, design the lip structure of the oil seal according to the working conditions (damping force, inflatable pressure) and the selected rubber, and design the outer structure of the oil seal according to the size of the guide and the chassis.
The evaluation of products is carried out from the following aspects:
Size, shape, radial force, friction, performance
