HOME THE STORY REFERENCE QUALITY CONTACT Suomeksi På Svenska In English Mapromec specialises in premium service and manufacturing SERVICES Machining of cylindrical components with high requirements, as example piston pins, shafts, rollers for fuel injection pumps and valve lifters, extension- and bearing parts for camshafts. The machining is mainly done with 5-axis machines. Our services are: Quality assurance, Traceability, Documentation, Nuclear projects, Ultrasonic inspections, Dimension measuring, Magnetic particle inspection, Machining, Heat treatment, Honing, Hard turning, Grinding, Superfinishing, Sub- assembly QUALITY ASSURANCE Quality assurance starts at the quotation stage and continues at each phase during and after production. We have ISO-9001 and ISO-14001 quality certificate. Our commitment is to be an excellent partner for our customers in respect of reliability, knowledge and responsiveness. We respect NDA and Supplier Agreement. TRACEABILITY Is a routine for us, we ensure complete traceability of the components. It starts by recording the melt numbers and producer of the material and ends up in a complete documentation of measurements and tests done to the product during the production.e production. DOCUMENTATION From our Product Quality Assurance Plan (PQAP) documents are delivered to the customer, but also stored so that they can be retrieved at any point of the products life cycle. NUCLEAR PROJECTS We are used to deliver parts also for nuclear power plants and for those a complete documentation of each step is a must. ULTRASONIC INSPECTION Inclusions or impurities in the material can cause cracks in highly loaded components. We want our quality to last and we are equipped with both automatic ultrasonic testing devices in the robot cells and a manual ultrasonic testing cell. We use the immersion method and state of the art equipment. DIMENSION MEASURING We are producing components with small tolerances, so we must be equipped and well educated to also measure these components. In addition to 3D-measuring machines we also have form testers with a very high accuracy and all the equipment needed to test surface roughness. MAGNETIC PARTICLE INSPECTION Is used to detect cracks on the surface of the material. Cracks can be initiated from the material itself or from local overheating during the production process. Through this inspection we make sure that the parts are ready for a long life without problems. TURNING – DRILLING – MILLING In our CNC machines and robot cells we are able to handle parts weighing 2–250 kg, with diameters of up to 400 mm and a length of 1,500 mm. The linear lathes have a high precision and allows us to control the surface of the parts already in the machining stage. The materials we are machining are different grades of steel. HEAT TREATMENT The improvement of steel and its alloys is a critical part of the production process. Through our partner, we can offer different kinds of heat treatments and special processes. Correct heat treatment improves material characteristics and extend its durability and lifetime. Together we evaluate different processes and through testing and measuring we increase our knowledge of the material behavior during the heat treatment process. As heat treatment asks for a lot of expertise and resources, we have decided that all our heat treatment is done by our strategic partner, a real expert company. HONING Honing of cylindrical holes is used when there is a tight tolerance and a need for a perfect surface finish. We have experience in providing this service and we have the necessary equipment.Using honing is an efficient way to finish holes which have a high demand on correct form and surface quality. We are equipped to hone holes up to Ø200 mm with a length of 700 mm. HARD TURNING Hard turning is performed on hardened parts. The hard surface means the process requires special knowledge. We have gained a high level of experience in hard turning over the years. Hard turning, which is done after the heat treatment is a bit different from turning of soft material. Mainly the differences are in the choice of cutting parameters and the cutting tools used. As we have done hard turning for many years, we have the experience needed to make it in an efficient way. GRINDING Many critical parts need grinding, and we are equipped to do both cylindrical and face grinding of the parts we manufacture. Grinding is a fast way to finish cylindrical parts and to get the right surface and the correct cylindricity and straightness of the parts. Our robot cells for grinding are prepared for unmanned operation as they have their own independent measuring stations which continuously monitor the quality of the parts made in the cell. SUPERFINISHING To ensure that the surface finish is correct, we use superfinishing grinding, lapping or polishing. PROCUREMENT We helps our customer to buy needed components and help to find suppliers if needed. We have ERP systems that support us in routine work tasks, this enable us to work cost efficient. SUB-ASSEMBLY For the assembly we have experience workers and flexible facility. This enable us to make assembly set- up and lay- out optimal. The customers will get assembled high quality modules delivered just in time. LOGISTIC We have office workers that can support production and take care of transport handling and documentation. So the customers can trust that they get their orders when they are confirmed. AB MAPROMEC OY Y:0630603-5 Teollisuustie 10 65610 MUSTASAARI FINLAND Phone. 010 2290150
