What You Need to Know About Torsion Spring Pricing
Buying stock or custom torsion springs should not be hard, that is why we made it our job at Acxess Spring to make it easy and affordable to obtain the torsion springs you need at the best price. Today we want to address some common questions regarding Torsion spring pricing and what you need to consider when deciding whether to buy a stock or custom torsion spring.
What Torsion Springs Cost is Based On
A torsion spring's price or cost is based on different factors. The main factors that need to be considered are the following: the amount of material being used, the type of material type that it is made of, the size of the spring, the manufacturing difficulty, and whether there is any additional labor necessary.
Material Type: The amount and type of material used in manufacturing can create a significant difference in the cost of a torsion spring. Some material types are harder to find such and more expensive which elevate the cost of production and based on the size and amount of material required this will affect the price of the torsion springs. Stainless steel tends to be a higher
Manufacturing difficulty: Spring index is a good factor to help determine the manufacturing difficulty of a spring. It is the correlation between the mean diameter of a spring and the wire diameter of a spring. This proportion will determine the strength of the spring, the stress induced on the spring, and the manufacturability of the spring. A spring with an index below 4 is not normally manufactured by Acxess Spring. Springs with a spring index of around 6-4 or around 10-20 will tend to be manufactured at a higher cost. Springs with an index above 25 are not manufactured by Acxess Spring. If you would like to learn more about Spring Index please visit our page here: Spring Index
Additional Labor: If you require a torsion spring with additional specifications such as plating, or legs with bends etc. all of this will be charged extra as these are not standard specifications and do require extended labor and resources which need to be quoted separately.
Custom Torsion Spring Costs VS. Stock Torsion Spring Costs
At our online stock spring website, TheSpringStore.com, we do not offer free samples but we have the most incredibly low prices on the highest quality stock springs. We have a minimum order limit of $40 USD which you are able to meet by buying several different designs if you choose to. This is quite convenient when it comes to testing and prototyping since you're able to test with different springs and therefore know what you're aiming for when it comes to ordering in larger production quantities. Stock springs are also great for when you need springs fast and can’t wait for several weeks of lead time.
Now when it comes to custom springs, you will get the exact spring dimensions you request considering the standard torsion spring tolerances. Custom springs are also very economical in high quantities. The pricing is based on the categories previously mentioned. If your spring has a tight index thus making it difficult to manufacture, the cost will be higher. If you have a large heavy-duty spring the cost will also be higher. With material types, Music Wire ASTM A228 and Hard Drawn ASTM A227 are the most economical although you may also use Stainless Steel 302 A313 which is the most economical type of stainless steel. Stainless Steel is necessary if your torsion spring is exposed to high temperatures or a corrosive environment.
Extension springs tend to have hooks on the ends which allows them to hold on to or attach to an object which will pull the spring’s coils apart by adding force. Since the function of extension springs is to be pulled or extended we can find different names for these springs which describe the function.
Pull springs:extension spring coils have no pitch in between them and are pulled apart by the force exerted on the ends. This is why the term ¨pull springs¨ can also be used as a reference to extension springs.
Tension springs:When the force or load on the ends of an extension spring pulls on the spring end’s the spring creates resistance and tension which is why this is another common term for extension springs.
Where to Buy Torsion Springs
After completing a design you're gonna want to buy the spring you need. If you're looking for prototypes or replacement springs, stock springs will be your best choice. Stock springs can be found at TheSpringStore.com and right now we have lowered the prices on over 23,000 stock spring designs. If you're looking for a larger production run, you can have your springs custom-made at our Acxess Spring website. You can also use our online torsion spring calculator, Spring Creator, and designing your spring for free! You will also get suggestions of similar springs in stock along with a Instant Spring Quote from the minimum quantity of 25 pieces to the maximum quantity of 25,000 pieces.
