Dear All,
I got an assignment to design a testing fixture to test the durability of the drawer slides at -30C.
Requirements :
Application : Freezers (-30C)
Load : 110lb (15 % push/pull force)
Test Cycles : 60000
Samples to test : 5 pairs with dummy drawers
My idea is to use the existing freezer and build the fixture inside it (easient way to test at -30C),and tu put actuator outside the cabinet.
Make a hole in the cabinet and pass the piston rod through it which will be linked to drawers by means of connecting member.
Need suugesiton:
the only concern i can see at this moment is the sealing of the hole where piston rod will pass through,and relibility of the seal
Please let me know if such seals are available as I dont want to take any risk on ice formation around the passage.
Waiting for response.
