Polymer Composite Modification
According to TMT’s customer requirements, through physical or chemical modification of rubber, plastic, and nylon, TMT has the ability to carry out “regeneration and cutting” to change polymer material properties.
For example, by modifying natural rubber and butadiene rubber blends; abrasion and low temperature resistance will be improved while at the same time expanding the scope of application. Varieties of elastic components manufactured in this manner are widely used in applications for automobiles, bridges, buildings and rail transit.

TMT is able to achieve structure simulation efficiency through its large team of engineers and ability to multitask the workload in different places at the same time. TMT utilizes ABAQUS, HyperWorks and FeSafe software. Analytically, TMT has the ability to solve problems from a total of two million nonlinear materials.
TMT has the capability to research products loading ability and property parameters, including structure design, strength and fatigue life calculation, to improve the reliability of products. TMT has the capability to analyze products from single components to full system unit analysis.
TMT has established dynamic simulation analysis ability of suspension and mounting systems for railway vehicles, automobiles and wind power. TMT is able to analyze and provide customers with entire system technology solutions.
TMT has also established the simulation analysis ability for construction and bridge bearing industries.
Vibration Analysis and Control
TMT has the ability to collect data and analyze vibration, stress/ strain, force and various other physical properties. Capabilities also include amplitude domain statistics, time domain analysis, frequency spectrum analysis, modal analysis, damping analysis and order analysis. Tests to evaluate vibration intensity and vibration comfort for the human body can also be analyzed.
TMT has a technical analysis platform for NVH product design. The platform includes property evaluation, engineering vibration control and structural dynamic property research and optimization.
TMT has adopted the use of finite element analysis software ABAQUS, ANSYS, NASTRAN and HyperWorks for structural modal analysis, harmonic response analysis, random response analysis, impulse response analysis and static strength analysis.
TMT has adopted ADAMS, SIMPACK, and MATLAB software for parameter modeling, multi-body dynamic analysis, decoupling analysis, and damping and stiffness matching analysis.
TMT uses LMS Virtual Lab, VA ONE and ACTRAN software for acoustic characteristics analysis.
Noise Analysis and Control
TMT has the ability to carry out noise source characteristic, localization and transfer path analysis. Other capabilities include structure and acoustic simulation to research a mechanism’s noise source. Noise control strategy effects can be forecasted, analyzed and optimized. TMT has the ability to test acoustic materials’ sound absorption, insulation and damping characteristics.
TMT has mold flow analysis capability, equipment structure and operation control analysis and superb design capabilities. TMT can carry out high tonnage injection molding design. Through operation of a servo manipulator, TMT utilizes double mold and cold flow process technology to allow for metal parts and components to automatically fit in and out of the mold allowing for improved production efficiency and reduced manual labor requirement. TMT possesses innovative molding technology. The company has developed a framework for automatic mold ejection and HALF automatic molding structures. New single mold structures and automatic integration technologies have also been developed.
In China, TMT was the first to develop a one-step molding process for an ultrahigh molecular weight poly-ethylene (UHMWPE) wear plate. In cooperation with various foreign manufacturers TMT designed a multilayer mold pressing production line. This production line can utilize multi-mold production or one-step mold production. This process helps to avoid the mass loss or buckling deformation due to machining and greatly improves the production efficiency and product quality.
TMT has researched and mastered wind blade mold technology. Three different blade types can be manufactured via the same mold, which saves mold purchase cost.
