Introduction Polyethylene terephthalate (PET) is one kind of semi-crystalline polymer material, which can be used as fibers, films, functional materials and bottles because of its excellent mechanics, solvent resistance, heat resistance, electrical insulation, stiffness and so on.
After modification, the crystalline material changes to amorphous material, which can easily be stretched up to 4-5 times elongation and sustain the large deformation without release them after cooling down, which will lead to high shrinkage performance after heating again.
COC/PETG Film manufacture COC/PETG=30/70 blending materials mixed before entering into twin-extruder, then cooled down by use of cooling roll and receive the base film with thickness about 200micron.

Introduction Piezoelectric motor is the collection acoustics, mechanics, electronics, automatic control, tribological mechanism for the integration of the subject, compared with the traditional assolenoid style motor, piezoelectric motor has the following advantages : 1) Piezoelectric motor are more energy density; 2) Machinery with the output torque and low speed characteristics of the work; 3) According to the characteristics of piezoelectric materials, can output the micro displacement, can be used for precision positioning table driven; 4) Piezoelectric motor does not use the electromagnetic effect of the working principle; do not contain their magnetic elements.
In the design of motor parts in the process of piezoelectric, make full use of mathematical modeling and numerical simulation auxiliary optimization design, such as in computer to oscillator wave characteristics, frequency and speed relations, the power input the volume and speed simulation research, then determine the basic structure, motor piezoelectric materials, dimensions, such as design and production parameters.
Substrate materials choose 45 # steel, and the base board processing to ensure that the plane of the parallel degree and roughness.
Rely on piezoelectric equation and pre-tightening force equation analysis, incentive stress analysis for ceramic materials to meet the requirements of the low frequency drive the lower conditions, for ceramic material parameter selection to provide the reference.
