The catalogue Polyurethane machine Made in Vietnam


The KNVN polyurethane machines

Base on the meticulous research on many kind of polyurethanes machines of leaders branch in the world, combine with knowledge about chemistry, mechanical and automation. With over 10 years’ experience in installing and commissioning, participation with many projects in domestic and international. Now we already made and delivery successful Polyurethane machines, Made in Vietnam, efficiency and reliability.













Reliability, high technology and easy control

         Mixing with high pressure help homogeneous mixture the chemicals, it is more effective and efficiency production, simplicity management. Use high pressure machine always give the highest benefit for enterprises.

         The KNVN high pressure polyurethane machine was designed for application of foam require accurately and reliability.

         This kind of machine suitable for small, medium size business. The devices have basic standard to high standard for reasonable investment.

The high pressure machine can use with additives, reinforce materials and special using for make rigid foam for insulation panel, refrigerators, freezers, or making flexible foam in mold for car seat, motors seat. The machine include production polyurethane integral skin, steering wheel, interior and exterior parts, wood imitation.

         The KNVN polyurethane high pressure machine ensure efficient production, environmental friendliness without using solvent after injection. The series particularly suitable for new enterprise during all the world consider to protect the environment and suitable for the companies change from low pressure machine to high pressure machine.




















Optional devices

Depend on demand of production, the KNVN high pressure can be equipped with specialized devices

         The mechanical joint of pump can replace by magnetic coupling, guarantee no leakage or flammable of chemical. The magnetic coupling makes the maintenance easier.

         The feeding pump can replace by pneumatic pump, reduce the situation spark discharge, special for using Cyclopentan system.

         The mixing head can be mounted on robot or on a frame can linear moving or cycle moving.

         Depend on requirement of customers, the machine can equip with pump of well-known branch name.

         Now we already supply special machine for use reinforced materials, machine for cyclopentane more friendly with global environment.

High pressure metering machine for Polyurethanes

-   Production interior and exterior 

parts of automotive

-       Insulation polyurethanes panel

-       Refrigerators, freezer insulation

-       Make in mold Rigid , flexible and integral foams

-       Pipe insulation

-       Special technical parts use 

bi-component chemicals.

 





The advantages on the KNVN polyurethanes high pressure machine     

High pressure machine alway have 

more technological advantages 

production:

-       High efficiency from maximum homogeneous mixing

-       Protect global environment base 

on no require chlorinated solvents to 

clean mixing head.

-       Improve the working place and safe for laborer from chemical solvents.

-       Finish products have higher 

physical and mechanical properties

-       More save chemical materials

-       Save cost for finish products.

Base on knowledge about science, technology with research about the advantages on well-know polyurethanes machine in the world. We already supply many metering machine meet the requirement of market.

Continously pay more attention in R&D, special consider to safety production, protect environment, efficiency. KNVN high pressure machine is the successful of technology and technical with simplicity management, it helps laborer easy to operation.

         For the devices enduring working and stable, KNVN design base on well-known spare parts, from main part: mixing head, metering pump, electronic parts. All the part follows CE standard and easy to replace.

         KNVN high pressure machine have neatly design, need small space to install, combine with open frame design, it is easy to maintenance and cleaning.

         The idea of design high pressure machine is “Plug&play”, that mean only plug power and working, the machine all time ready to production and make benefit for end user from beginning. 



Machine configuration

         The machine configuration can design follow requirement from customer, based on the basic following technical feature:

-       Automatic adjust output by frequency inverters.

-       Manual adjustment output and ratio of chemical of metering pump, help save cost of maintenance.

-       Set automatic pouring program on touch screen.

-       Close loop control the output and ratio of chemical, set the value constantly during real time pouring, based on the tolerance parameters adjustment device.

-       Pouring parameters show on main touch screen.


The standard KNVN high pressure always equipped with:

-       Two layer steel tanks, insulated by oil or water, capacity 70-250L.

-       Heat exchangers

-       Electric heating use thermistors

-       Recycle stream of chemical distributors

-       Tank sight level, use visible hoses or magnetic, help control the level of chemical inside tanks for automatic or manual feeding.

-       Touch screen to set parameters of pouring and operating of machine.

-       “Holiday cycle”  was set for the machine automation running prevent sedimentation in the tank, pump.. during long time machine off.

-       Save plugs help operation and maintenance more easy.

-       The special hose for transport chemical. Anti-corrosion and anti-solvent.  

-       Filters for remove sediments

-       Mechanical stirrers for material tanks help homogenous mixture and stable temperature of chemicals inside tanks

-       Gear pumps for automatic feeding materials.













The KNVN polyurethane low pressure machine

         The low pressure machine can make almost products like high pressure machine with low investment. This machine special suitable for small and medium entrepreneur just joint to production polyurethane products.

         The polyurethane low pressure machine suitable to make following products:

-       Rigid foam, flexible foam and integral foam.

-       Production small parts.

-       Using for silicone bi-component in electronic part.

-       Using for epoxy two component

-       Elastomer polyurethanes

For the start up in polyurethanes products, low pressure is the best choice. Low investment, can be used for almost application of polyurethanes. The fundamental of operation of low pressure similar on high pressure machine.

         Base on synchronous design and open structure. For upgrade from low pressure to high pressure need only one feet, KNVN grow up together with customers.

 












Features of machine






Some kind of special application for market.

Beside normal application of polyurethanes as: panel insulation, refrigerator, water heater, flexible foam for furniture, automation, motor seats… KNVN still supply for some kind of special application:

-       Sealant for small box, electrical box

-       Making phenolic foam

-       Elastomer for sealant

Polyurethane brick, curtain for gym room and stadium.
