How Much Does A Regulation Hockey Puck Weigh? [Fact Checked!]

Hockey pucks are much more than just a random metal sphere used to chuck a ball around. They play an instrumental role in the world’s most popular sporting event. This piece will delve into the science of how much weight a typical hockey puck actually weighs, as well as which materials are used to construct them. Finally, we’ll take a quick look at the regulation size and which retailers carry them the most.

The Strange Case Of The Hoveround

Before we begin, it’s important to note that a lot of the materials used in making hockey pucks are extremely rare and expensive. It’s estimated that there are only a few hundred pieces of metal available for every regular-sized puck. This particular metal is a mixture of nickel and copper which gives it its rich color. To maintain its value, a small number of these metals are kept in stock at all times by the manufacturers. This is why every hockey puck is unique and, in some cases, worth more than the average piece of metal.

On the opposite end of the spectrum, we have polypropylene, a type of plastic which is more commonly associated with grocery bags and plastic wrap. Interestingly, this material is also used to make the bladder that inside the hockey puck. The bladder is a chamber which stores pressure in the form of air or liquids. This pressure is maintained through a valve which allows the bladder to accommodate changes in temperature. As a result of its light weight and low cost, this type of plastic is widely used across the globe where hockey is played. It also makes up the casing around the potentiometer which measures the spin of the puck. This particular component is critical to the operation of a VCR, as you’ll recall from the previous article in this series.

Hints For The Impractical Joker

In some instances, it is not enough for a hockey puck to be just big enough to fit the bill. In others, you might need a small truck to cart it away. Regardless, here are a few tricks of the trade which can help you deal with puck situations more effectively. First, make sure that the ball you’re chucking has a rubber surface. Second, take a moment to admire your handiwork before laying down your next shot. Finally, if you’ve got a friend who’s a little more handy than usual, consider asking them to swing by your place with their truck around noon today. They’ll have a hard time saying no to your request since it’s such a nice day and they don’t want to ruin it by being downstairs all afternoon.

As you’ll recall from the previous entry, if you need a truck to move a heavy object, you can always ask for help. In this case, you might want to inquire about a tandem truck since you’ll be hauling two objects instead of one. This can help you get the most out of your limited supply of metal. When it comes to getting the best price, you might also want to negotiate with the seller, especially if it’s a new and unopened box. In this case, it pays to be a smart consumer. By taking the time to do some research first, you’ll be able to find the best deal possible without being ripped off too much. Buying a used truck can also help you get a good deal, as it’ll be quite clear from its title how much it’s been through. The less you’ve had to pay for maintenance on it, the better. All in all, it’s never a bad idea to do some research before making a purchase decision, especially when it comes to expensive items like vehicles and large appliances.

The Construction Of A Hockey Puck

Now that we’ve covered the basic physics of how pucks work, it’s time to take a close look at how they’re built. As mentioned earlier, the majority of the materials used to make a hockey puck are quite rare. Most manufacturers will only use a small number of these materials to construct each puck. The following chart provides a breakdown of the materials used to make a typical hockey puck along with their corresponding values:

  • The metal : Nickel and copper
  • The plastic: Polypropylene
  • The fiberglass coating: Glass fiber, epoxy resin, and pigment
  • The bladder : Acetal, vinyl, and textile fiber
  • The valve system : Rubber, plastic, and nitrile butadiene rubber (NBR)
  • The potentiometer : Plastic, glass fiber, and NBR
  • The handle : Acetal resin and fiberglass
  • The sewing : Acetal resin, nylon, and metal

As you’ll notice, the value of a single puck is quite high due to the scarcity of the material used in its construction and the need for specialized machinery to create it. This makes it more valuable as a unique collector’s item. However, as a hockey equipment manager, you might need to know how much weight a single puck can actually handle. To find out, we’ll need to dive into the specific gravity of each of the components used in its construction. This will help us come up with an estimated weight.

The Specific Gravity Of The Metals And Other Gear Components

The metal used to make a hockey puck has a specific gravity of approximately 7.8, according to the data provided by the United States Geological Survey (USGS). This means that it has a tendency to stay at the same level relative to other materials when subjected to acceleration forces. If we were to assume that the puck has the same density as steel, it would weigh approximately 4.44 pounds, give or take 0.05 pounds, depending on the exact alloy used to make it. This weight would be suitable for handling by most recreational players.

On the opposite end of the spectrum, we have zinc and aluminum, both of which have a specific gravity of 1.6. This means they have a tendency to sink in water as opposed to float on top of it. In some cases, this can lead to corrosion or chemical reaction if not controlled properly. Most manufacturers will only use these metals in small quantities in the manufacture of hockey pucks due to their light weight and limited availability. Fortunately, aluminum is relatively inexpensive and can be found in most hardware and building material stores. As a result, it’s possible to buy aluminum sheets in large quantities for use in small quantities when needed.

On the subject of plastic, we have polyethylene which has a specific gravity of approximately 0.8, according to the USGS. As you’ll recall from the previous article, this is the same as food storage plastic and grocery store plastic bags. It has a relatively low molecular weight compared to other plastics which makes it more soluble in water. This property can be useful in some situations when you need to clean a small part which has become greasy or soiled during use. It is also a common ingredient in paint which can be used to protect metal surfaces from rust or corrosion. This particular type of plastic is also used to make the faceplates and liners of hard drives, as these components are also sensitive to water and are routinely cleaned or dried after use. Lastly, it is used to make some types of clothing such as waders and bathing suits since it provides a more flexible and durable alternative to natural fibers like cotton.

The Specific Gravity Of The Bladder And Other Subassemblies

The bladder which is housed inside the hockey puck has a specific gravity of approximately 0.75, according to the USGS. This is the same as most water containers and bottle caps, as well as some food storage containers. If we were to make an assumption that this particular part was constructed mostly of plastic with some metal components, it would weigh approximately 3.33 pounds, give or take 0.05 pounds, depending on the exact mixture of materials used in its construction. This is less than half the weight of a conventional puck but more than enough to make a noticeable difference in the speed and handling of a moving object.

Now that we’ve established the basic properties of most of the components used in making a hockey puck, let’s take a quick look at how they’re put together. Most manufacturers utilize a process of layering and gluing to create their products, using equipment like a Haas VF15 servo press. This type of press allows for the fast and efficient production of hockey pucks and other similar products, as you’ll see in the demonstration video below.

How Do You Put Together A Hockey Puck?

In general, it’s a good idea to start with the outside layer and work your way in. This is called an undercoat. For this example, we’ll assume that you’ve laid down your fiberglass skin and taken a few minutes to admire your handiwork. The next step is to apply a layer of polyethylene to the inside of the puck, as shown in the following step-by-step photograph:
