We manufacture a Compression spring out of 0.026" tolerance +/-0.0003 wire diameter music wire per astm A228. We send the part out for a commercial thk .12 mil min tin plate. Weird thing occurred when we received the parts back and measured the wire diameter cross section-ally the wire...
I have a technical question about a compression spring we make for a customer. The spring is made of 316SS spring temper per ASTM A313. The problem that occurs is the customer places the compression spring into a mold so the spring is under some compression, about 20% of the deflection and the...
Material: 0.014" Nitinol # 1 condition cold worked spring temper surface finish: etched and polished.

Looking for any online resources for manufacturing guidelines.
Thanks
I am trying to verify a customers design of a magazine spring. The spring dimensions are as follows:
Material: Music wire
Wire diameter 0.032"
Width ID .775"
Height ID .157"
Free length 4.85"
Total coils 12
Looking for forces at heights 2.798" & .890". I have attached a drawing for reference...
I have a customer which we manufacture springs that get shotpeened and the customer is having issues with the shot media getting wedged in between the last active coil and closed coil. The spring is used in a hydraulic pump and they do not what any foreign material that could cavitate the pump...
We are manufacturing a antenna spring made of music wire per astm a228. The customer is asking for a coating to be placed over the material. The spring will be used on a clock and will only be used in doors. Does any one have any ideas of a plating or coating to use? I have attached a...
I have a Compression spring made of .375" 17-7 stainless steel, and it has to have a 45 degree X 3/32" deep chamfer on the inside diameter. What would be the most suitable deburring tool to use and out of what material? Is it better to have more flutes of less?
I am designing a spring which will be immersioned in potable (chorinated) water.
With an operating temp -25 degree f to 150 degree f
Which series stainless steel should be used?
We are looking to purchase CBN grinding wheels for one of are new grinders, but one of are suppliers said that CBN wheels cannot cut through 300 series due to it low Rockwell Hardness. Does any one know of a CBN wheel being designed to cut 300 series stainless?
Any information would be greatly...
We are manufacturing a burner mount support out of 0.020" tungsten wire. We are cutting the material off the machine against a quill. The quill and cutoff tool is made of Tungsten Carbide 10% Cobalt. Once each part is cutoff we are finding a small burr about .003" to .005". We used Tungsten...
We are manufacturing a ring made out of .375” 302 stainless steel per ASTM A313. The ring as a 2.5” Inside Diameter and is Stress Relieved at 650 degs F for ½ hr after cool working the part. Then the part gets butt welded together. After the butt weld we feel that the part should get another...
Expect an increase in spring wire (ASTM A227 and ASTM A228). About 450 workers at Ivaco Inc.'s steel-making operation near Hawkesbury, Ont., are off the job after failed contract talks. They supply about 40% off rod to the Spring Industry.
We are coiling a compression spring with a 25 spring index
and the springs ends on some of the springs are not closed to the coil, but seem to be slightly open. What would cause this? My opinion is that the wire has a poor cast or helix.
