If a spring is to be used in a cyclic condition (compression or extension), it should be stress relieved in a heat treat oven to reduce the manufacturing stresses. It will increase the spring properties and also increase longevity of the spring. Non-heat treated springs fail much earlier and also take a heavy "SET" during the first few uses, which changes their lengths and rates. If however, the loads are very light duty, a spring may not need stress relieve, but unless the customer has specifically said NOT to relieve their springs, I would still quote a stress relieve process, as a preventive measure. Most engineers who design springs for their assemblies don't understand how springs are made. Too many customers will request springs/wire-forms, and later after they've used them complain of "set". After heat treat, they perform as expected, but of course have to be made again if the hook orientations rotate too far during heat treat.
@@ow-my-achilles1106 It depends on the material used. Every use is different. Some torsion springs if manufactured using wire such as beryllium copper need highly stress relieving due to the fact that the raw material is so soft. Compression springs in Stainless steel need lower temperatures in order to prolong life and reduce the risk of fracture.
@@ow-my-achilles1106 Can we create a 30mm wire spring, form the first coil, and then perform a heat treatment until it turns reddish, followed by quenching in oil?
@@babajeesprings3963 I haven't even done big wire parts. No spring bodies over a wire diameter of Ø.125 inches (about 3mm) It depends on so many conditions. Diameter of spring body is Ø30mm or the actual wire (I would call it a rod) is Ø30mm in diameter? Not all spring material needs to be red hot for a stress relieve or hardening process. I make medical springs, and they are small wire diameters and generally are also small springs, used in surgery instruments. Always stainless steels. Never music wire or HDMB. At one employer, all I did was truck brake springs for spring kits. It was HDMB (watermark) or oil tempered quench music wire, right out of the inline oven. We even had a painting conveyer that dropped 650°F springs into the paint vat, and conveyed then out in a few seconds under a blower and they air flash dried out, and were packaged all within 60 seconds after falling out of the oven (10 minutes). Talk to a metallurgical engineer about the time. temperature, and duration of the heat treat, and also the type of oil you may need for quenching. The oil might need to be at a certain temperature as well. And there may need to be a follow up heat treat stress relieve after that to make a durable spring. Forming a spring is just a part of the process.
Please price
In this machine can springs for the gun magazines be made?
Hi can you share me the manufacturer details please
Which material is used to manufacture this Coils spring it's a Heated or not
I worked making springs like this for over 30 years and it’s not heated.

We are big spring coilig machine manufacturer,you can add my whatsapp:0086 15703791716
How much cost of this machine and I want to purchase
Have you purchased the machine ?
Me encantaria trabajar con ustedes🤤🤤🤤
It's fun to know those have springs inside while making springs
