"Exploring Quality Control: Survival of Microfluidic Components in Extreme Environments (May 18, 2024)"
Under the dual drives of global layout and technological innovation, diversified markets have put forward higher requirements on the performance standards of fluid components.
Therefore, designing fluid core components that can maintain stable performance within a certain range requires comprehensive solutions to material selection, structural design, and production processes. Let's see how Kontur resolves this issue.
Environmental Verification Control
Environmental testing is one of Kontur's environmental verification laboratories, equipped with high-function ovens and programmable constant temperature and humidity chambers, with the highest settable temperature of +160℃ and the lowest settable temperature of -40℃. The performance verified includes: product high/low temperature operation verification; product high/low temperature storage verification; product thermal shock verification; material high/low temperature storage; and material thermal shock verification.Due to environmental temperature differences in the areas where end customers are located and within the equipment, Kontur's micro-valves, precision pumps, flow path components, accessories, and consumables need to be capable of operating in harsh environments. The purpose of building the laboratory is to simulate product operation conditions in extreme environments, monitor their operational data, optimize performance, and enable products to withstand harsh conditions.
Strict Material Selection and Measurements
In material analysis and control, Kontur deeply analyzes the coefficient of linear expansion of the materials. The coefficient of linear expansion reflects the change in the shape of the material due to volume changes caused by temperature changes. Based on this, we can accurately predict and control the thermal deformation of product materials.
Exploration of Processing Techniques
In processing technique control, we reduce the temperature gradient within the material by optimizing heating and cooling processes, thus lowering thermal stress. We also employ pre-deformation technology, where materials undergo pre-deformation treatment before processing to release internal stress, reducing thermal deformation during processing. The use of fixtures to limit free deformation further minimizes thermal deformation.Finally, based on the coefficient of linear expansion and thermal conductivity of the material, we select appropriate processing parameters (e.g., cutting speed, feed rate, cutting depth) to further reduce thermal deformation of the material. Risk Assessment in Design and DevelopmentIn design and development control, Kontur's R&D team uses temperature compensation design to address size changes or performance degradation of components caused by temperature changes. Through optimized structural design and material control, the impact of temperature changes can be partially offset or compensated.Additionally, we employ temperature control design, using appropriate insulation materials or layered insulation structure design to reduce the heat transfer rate between components, thus minimizing the impact of external environments on the components and improving their stability and durability. Kontur's Quality Control AdvantagesAdvantage 1: Regardless of environmental temperature differences, internal equipment temperature differences, or temperature alternations during transportation, these components can withstand lengthy trials through refined temperature control quality management, thereby effectively reducing maintenance and replacement costs due to material aging or performance decline.Advantage 2: Products implementing temperature control management possess an excellent wide temperature tolerance, significantly enhancing the lifespan of customer instruments and equipment.Advantage 3: Due to the advantage of wide temperature tolerance, the market coverage of entire instruments can be broadened, meeting usage requirements in regions with significant temperature variations or extreme environments. In recent years, with the continuous improvement, in-depth optimization, and innovation drive of Kontur's quality management system, our fluid component products have demonstrated outstanding advantages and application value in diversified fields.In the future, Kontur will continue to increase exploration in new materials, advanced design, and technology to further enhance the adaptability and broad application of fluid components.Additionally, we will explore and meet the diverse needs of customers, committed to building a more adaptive, maintenance-free, and excellence in precision product ecosystem, injecting continuous innovative momentum for the thriving development of the fluid component industry.
