PLATE SCALE FOR DUST CONTAINMENT
In the multi-head weighers, dust’s containment between the vibration transmission shaft and the machine surface is normally achived throw bellows, whose frequent lacerations often require maintenance service.
One of the most important Italian technical equipments retailer asked us to realize a spare part with a better fatigue resistance than the original component and able to guarantee the same functionality in the machine.
As usual ATP’s team started from the analysis of the application.
- Contact products: food product powder;
- Operating temperature: room temperature + 15 / + 35 ° C;
- Cleaning: high pressure compressed air + COP;
- Cleaning: high pressure compressed air + COP
- FDA and UE 1935/2004 (MOCA) certifications,
- Assembly in existing seats (no modification of machine admitted)
After analyzing the damaged part our team developed a bellow in SINTEK® H-TPU. Thanks to FEM analysis our technicians refined the geometry of the profile and realized some samples to test on the machine.
Evaluated the functionality of the replacement and verified its reliability we proceeded with the production of the entire lot, which was delivered accompanied by MOCA documentation.
The particular shape of the profile, the possibility of predicting the areas of greatest stress (thanks to the use of FEM analysis) and the use of extremely high-performance material have premitted to our solution to drastically reduce the number of maintenance works.
