UV-LIGA Project The aim of this project was to develop a reliable, repeatable and relatively inexpensive method for the production of METAL-structured MEMS devices. In this project which lasted three years, the company succeeded in creating a repeatable advati with nickel structural layer and copper sacrifice layer with low sensitivity to clean room conditions and low cost. The method used was UV-LIGA and futversist used by KMPR. The maximum height created in the project was 50 microns and the minimum built dimensions were 10 microns. The result of this technology is the manufacture of microheiters, micro-grippers, inertia keys, comb stimulants, etc. Was.
Comb Stimulus Project Comb stimuli are very common structures in microtechneury (MEMS). This structure is used in the production of acceleration sensors, gyroscopes and electrostatic operators. The aim of this project was to investigate the feasibility of constructing these actuators by METAL MEMS method. One of the challenges of this project was the creation of a suspended spring-mass structure and its release along with the comb dents in high density. The project has been successfully concluded.
Nano Filter Project The aim of this project was to provide a simple, standard and highly repeatable process for composite fabrication consisting of polydimethylsiloxane and silver nanoparticles in order to increase the gas sputum. The application of this composite is in the separation of olefin/paraffin compounds by “nanoparticle-assisted transport” method. To produce a composite capable of separating the mixture of olefin and paraffin, it is required to make a thin membrane with high reliability. Olefins are polyunsaturated compounds derived from hydrocracking process and are used as raw materials for the petrochemical industry. In fact, ethylene, which is an unsaturated gas, is the most valuable gas for many petrochemical processes. By making this filter, it is possible to separate the materials with a boiling point close together without the distillation column. The response to this project in the laboratory stage was very promising.
Microheiter Project Microhitters are small heaters with high power and precise control that can provide temperatures over 1,000 degrees Celsius, even up to 1,900 degrees Celsius. Microhitters provide precise control of high temperatures. The heating method of micro-heaters is to convert electrical power into high-density heat. These microstructures are used in various equipment such as electron microscopes, pressure cells, Fuel Cell heat source, electronic substrate heating, RF applications, gas microtube heating, fiber optics, Olfactory sensors, material testing and identification, gas converters, etc. are used. The aim of the project was to build a microheiter with a temperature of 1,300 degrees Celsius in 30 milliseconds. At a voltage of 2.5 volts, this microhiter creates a temperature of 400 degrees with a delay of 20 milliseconds.

Inertia Key Project The work of inertia keys is to activate a system when reaching a certain acceleration. For example, in a car’s airbag, it acts as soon as a heavy shock (accident) enters the active key and the airbag. Or in race cars, the inertia key is used to cut off fuel flow when a car crashes or suspends to prevent a fire. The aim of this project was to build the key to inertia and provide a method for mass production in the country.
Micro Gripper Project Microgripers play an important role in cellular studies and research. The way cells are captured, not damaged during gripping and displacement, and the convenience of working with it under a microscope are important in the design of these microgriders. The aim of this project is to design and construct a microgriper for in vitro fertilization and cellular fertility applications.
Improvement of ceramic deregulation and dissolution in high pH environment in laboratory dimensions  In the casting of complex parts such as turbine blades, it is necessary to clear the intricate and intricate corridors and ducts from the ceramic muscles. Increasing the dissolution rate and muscle output without damaging the casting metal will increase the speed of production and reduce costs. In this project, by adding different surfactants and suitable additives along with some mechanical techniques, the process speed at the laboratory level doubled, which is anticipated to increase by at least 50% in the industrial process.
Feasibility study of turbine blades using light-baked polymer-ceramic slurry The casting of turbine blades consists of 12 main stages. Reducing each of these steps leads to cheaper production of the product. The aim of this project was to feasibility study of the production of ceramic molds with 3D printer and stereolithography method. At the end of the project, a ceramic cup with 3D printing method should be produced and provided to the employer to fill it with molten inconel. The cup should have a molten holding warp and break easily after cooling the molten. The project has been successfully carried out and proved feasible for the employer.
Presentation of steel laboratory automation plan In steel companies, molten samples are prepared for the preparation of beds, ingots, etc. It should be controlled continuously in terms of material analysis and when reaching the desired combination, molten discharge orders should be ordered. The speed of analysis and response sending can greatly reduce the cost of electricity and equipment repair. Currently, this process is done manually in laboratories. Lab automation can greatly speed up the process. The aim of the project was to present a plan for automation of the steel laboratory with constraints specified by the employer.
Fabrication of painters for car-carrying skids  In the automotive industry, the body of the car is immersed in the paint dock and then cooked inside the furnace to find the right strength. Some parts, such as doors, trunks, etc. Hinges must be opened and fixed by special fixtures so that the seams and inner parts are also painted. These fixtures are also immersed with the car in the paint dock and then cooked in the furnace. That’s why, after using on several cars, it takes a thick layer of paint cooked on the fixture. The aim of this project was to create a paint that can separate the thick layer of paint without the need for basic physical work on the piece and can be reusable. The project was successfully carried out and 17 tons of paints were provided to the employer. The employer painted 600 kilograms of fixtures every week. The durability of the paint was eight months in the project.
Educational Workshops Rasa Company is able to provide workshops in various fields such as microfluidics, process design, lithography, etc. has.
