Solution for Polyurethane INTRODUCES DUT KOREA'S TRUSTABLE TECHNOLOGY. CARES REQUIREMENTS FROM ORDERS TO YOUR GREAT SATISFACTION. PRODUCTS DUT has committed total quality control section for continuous improvement activity and will do our best step by step with providing high quality products based on measure equipment and reliability equipment. In the field of Polyurethane industry, everyone know the Mixing Head as core of technology of Polyurethane Injection Machine. It decides mixing efficiency of Polyurethane Injection Machine so most of people who belonged in this field are interested in the technology of Mixing Head. Currently DUT is leading the industry of PU High Pressure Injection machine and Mixing Head. In 1992, the specialist of JIG in Korea, Jeong Young Chae established DUT as manufacturer then the life of company was hung upon development of Mixing Head. It took almost 10years to develop from benchmarking of European products to development of DUT's own. DUT has number of hardships and troubles during the 10 years but after that, the brand name of DUT became powerful as specialist of Mixing Head. Also steady efforts for development and research are linking to produce innovative new products. Already major companies in Korea such as Samsung, LG, etc they are operating plants with DUT's High Pressure Injection Machine and reliability of machines are already proven by hundreds of companies. So the unrivaled technology of Mixing Head is linked in the other parts as Pump, Flow meter, SD V/V etc then it makes better compatibility for high efficiency mixing system. Now the reputation of quality of DUT is spreading out all of the world and DUT keeps business with 52 countries such as USA, China, India, Japan, Germany and England etc. (DHVA 12K Mixing Head) WORLD PATENTS 1. Mandrel of Invention 2. Ball Lock Retainer 3. Mixing Head for Polyurethane High Pressure Foaming System 4. Cleaning rod spiral groove in mixing head assembly 5.

(DHV 2K Series) (DHVA 2K Series) (DHS 2K Series) (World Patented Double Tilted Injection System) (General L-Type Injection System)

HIGH PRESSURE METERING PUMP Light weight pump for high pressure injection machine ( DUT's new developed pump 'DMP' is type of 'Axial Piston Variable Displacement' and it designed to improve the weaknesses from the existed metering pump but DMP has perfect compatibility with existed products and weight lightening has applied by using duralumin case.. DMP Light weight duralumin metering pump Also simplification for components inside of the pump made even much lighter, so integrators can be maintained and replaced easily. And the other point is that existed screws for 'Mechanical Adjusting Gear' have replaced by 'Fine Pitch', so operators can exact adjusting for outputs. for metering pump in this field. SD VALVE High-Pressure Switching Valve Optimized design for DUT's High Pressure Injection System To prevent flowing backward, it is controlled by actuator (Not by Hydraulic) Semipermanent product life by superprecision machine Fast high pressure building time by air actuator

HIGH PRESSURE INJECTION MACHINE Ultimate mixing efficiency with various options High mixing efficiency Stable laminar flow Suitable for rigid and flexible foam Innovative nozzle control Long operating life Low maintenance cost Economical and reliable MAMIX High Pressure Injection System MAMIX have various options for customer's convenience so assembly by their needs becomes available. DUT are the one of leading company and only the manufacturer for both mixing head and metering pump in the world. Those are most important components to assemble high pressure injection machine so compatibility of each parts are very stable and flexible. Also DUT have long range of products line including mixing haed and spare parts, so it makes perfect output from customer's need. After building machine, PLC program is designed for only the machine, so every works are processed and finished by DUT.

APPLICATIONS Total solutions for polyurethane industry Application belongs to system technology and the point is compatibility. It means offering most stable and convenience system for operators. From mixing head to huge plants, DUT offers best solution by total compatibility. Also the applications let customers to choice various type of options depending on their situations.
