How To Maintain PU Foaming Machines

The well-known PU foaming machine primarily produces PU series items. Impact mixing creates an equally synthesised machine body made entirely of a stainless steel frame. What, therefore, must you do to upkeep your PU foaming machines? First of all, before beginning any operation on the device, it is essential to thoroughly study the complete operations manual with special attention. All workers using the equipment must be informed of the directions, which must also be displayed in a way that is both visible and accessible in the workplace.

Why Is Maintenance Necessary For Foaming Machines?

The goal of equipment maintenance in the industrial industry is clear: to reduce expensive breakdowns and guarantee that your continuous foaming machine performs at its peak efficiency. However, a segment of the production community still sees maintenance as an unnecessary waste of production time. There are seldom enough hours in the day in a production facility to finish the work. Producing the parts as rapidly as possible to fulfil customer orders is the only option if they exist.

The element of surprise associated with machine failure is eliminated from the facility by ensuring the equipment is maintained correctly. Regular equipment maintenance and prompt replacement of old machine parts increase machine life and reduce the risk of rework or scrap products due to manufacturing materials outside specifications.

Proper Maintenance Of Polyurethane Foaming Machines

1. Air Pressure System Of PU Foaming Machines

Once a week, our equipment needs to be dewatered to keep the moving parts lubricated. Petroleum jelly can also be used to lubricate the measurement head and dispenser head frames. Remove the fuel tank vent valve once a month to clean the intake passageways and sealing components. Butter can also be applied inside for lubricating defence.

2. The Hydraulic System

The filter shouldn’t require frequent cleaning. Cleaning it every six months is possible. Every two cleanings, the filter needs to be replaced. Every six months, replace the hydraulic oil. Hydraulic oil or petroleum jelly are more options for lubrication. The hydraulic reversing valve and the oil tank’s interior mechanical components should be cleaned yearly while changing the new oil. A hydraulic diverter valve’s lifespan is roughly two years. This must be kept in mind.

3. The Raw Material System For PU Foaming

The dry air must be nitrogen to meet the raw material tank’s pressure requirements. Every year, we must remove the filter, clean the interior with methylene chloride and a copper brush, and then use DOP to remove any remaining methylene chloride from the filter paper. Seals for the white material variable pump are changed every two quarters, whereas seals for the black material variable pump are changed every three. Every six months, the measurement head and dispensing head’s O-rings should be changed.

4. PU Foaming Machine Mixing Techniques

The nozzle’s body should only be disassembled if there is a problem. Following maintenance, the nozzle head can be used constantly for about 500,000 injections.

5. Controlling PU Foaming Stagnation

There is no need for extensive control if it is within a week. When the machine starts up after a lengthy downtime, the feedstock must undergo a low-pressure cycle and, on occasion, a brief (10-second) high-pressure cycle (about 4 to 5 times).

Conclusion

Keeping your facility’s equipment in good condition can provide your clientele with the highest-quality service. This distinguishes you from the competition and ought to motivate you to ensure no maintenance problem is overlooked. Machines that are kept up to date consistently produce the most incredible work and maintain the positive public perception of your institution. We are the leading foaming machine manufacturers in the industry. At Santech, we believe that without your production equipment, your company might cease to exist. Every piece of equipment in a facility ought to be considered essential to its success.
