Motion. Including speed, acceleration, displacement, force, etc. they have an important impact on the dynamic performance and motion control. For example, when designing a threaded rod for robotic arm, we always consider its working range, speed and accuracy to meet a specific work task.
Thermal. Including temperature, heat conduction, thermal expansion of precision components, etc. they have an important impact on the thermal stability, heat loss and thermal stress. For example, when designing precision metal for an engine, we always consider its combustion chamber and the thermal conductivity of its cooling system, to ensure the engine’s operational stability and life cycle.
Environments
Environments of precision components. We always design and manufacture precision components to respond effectively to harsh environments, such as high temperatures, low temperatures, high pressures, corrosive environments, and strong radiation. The design and manufacturing of precision components always face great challenges in harsh environments. we always ensure stability and reliability through reasonable materials, and design, as well as measures to strengthen insulation, lubrication, anti-corrosion, and sealing.
High Temperature. it is a place exceeding 150°C. The strength and hardness of precision components are reduced, while the stability and mechanical properties of plastic precision parts are greatly reduced. Therefore, a special cooling process is required to ensure the stability and properties of precision components.
Low Temperature.
