Leading Weatherstripping Manufacturers

While the scope of industrial and commercial applications for weatherstripping is limited, it is an essential product to many industries. Some manufacturing companies dedicate all of their extrusion lines to the production of different kinds of weatherstripping. Weatherstripping functions primarily as a door and window insulator. Specifically, it fills gaps between the moving parts of doors and windows and their fixtures.

In the automotive industry, weatherstripping for car doors, windows, trunks and hoods is indispensable. In the construction industry, particularly in geographical areas where cold weather is a consideration for residential builders and maintenance professionals, weatherstripping is becoming an increasingly important part of energy-efficient climate control. Weatherstripping products also have limited applications in industries that manufacture ice machines or storage refrigerators.

All weatherstripping products are processed with rubber extruders, which are machines that convert raw natural or synthetic rubber materials into strengthened, functional products. An extrusion line begins with a collection of rubber pellets in a hopper that directs the raw material, or stock, into a conveyor channel. The hopper is usually placed above an opening in the conveyor channel, and gravity sends the stock into the channel. In most rubber extruders, the conveyor channel is equipped with a long screw that moves and pressurizes the stock while it is heated. Near the end of the channel, the pressurized, heated stock reaches a near-liquefied state and is ready to be forced into the die.

A die is a tool that is used to create hardened shapes out of a given raw material. In the case of weatherstripping dies, the die will be a narrow hole through which the stock is forced. As this happens, the stock takes the shape of the die, which it keeps once it has hardened. The newly extruded rubber may at this point be cut and shipped, or it can continue to additional processing if necessary. For use in demanding applications, like in the automotive industry, weatherstripping may be cured with sulfur or other curatives in a process called vulcanization. This process improves the rubber's strength and durability, making it more weather-resistant.

Car weather stripping is known by many names such as car door seals, automotive seals or car window seals and refers to the rubber seal found around car doors and windows. These seals are responsible for keeping warmth in and keeping the rain, dust, dirt and bugs out when your car door is shut. Weather stripping for cars also helps to make a car journey comfortable as they prevent drafts and help to keep outside noises to a minimum.   
As useful as they are, rubber seals for cars don&#;t last forever, so it&#;s useful to know what to look out for when it comes to car window rubber and car door seal replacement.

When Should I Replace Weather Stripping On My Car?

As we drive around in our cars, we seldom think about car weather stripping until something is wrong with it.  
Have you noticed that your car doesn&#;t stay warm when the heat is on or perhaps you&#;ve heard a whistling noise while driving? Either example could indicate that it&#;s time to replace your car door rubber seal.  Here are some signs that your car door seals need to be replaced:

• Leaks in the car. Water can travel down the car door seals, into the car interior, leaving damp areas that over time can leave a smell.
• A whistling sound is heard while driving. This usually means that there is a gap in the car window trim seal.
• Loss of heat. If you notice that the car is no longer retaining heat well when windows and doors are shut,  this is a good sign that the car door weather stripping should be checked and replaced if necessary.
• The rubber seal doesn&#;t feel bouncy. If your car rubber seal looks flat, feels stiff and doesn&#;t bounce back to its natural shape after squeezing, then this is a sign of an aged car window rubber seal. The effectiveness of the seal relies on good quality, flexible material that retains its shape after being compressed by the door. If the rubber seal isn&#;t sealing properly, you&#;re at risk of water inlet during wet weather and creepy crawlies finding their way in.
• The car door seal has visible holes and gaps. An old, worn seal will begin to crack and crumble away leaving holes and gaps and will render the seal useless. 
• The door sounds louder when shut. This is another clear indication that the seal has worn out and is not as flexible as it once was. The door isn&#;t being cushioned by the bouncy seal anymore so the door sounds louder when closed. Being able to hear outside noises loudly from inside the car can also mean the seal isn&#;t doing its job.
• The car is an older model. If the car is more than 20 years old, it&#;s worth replacing the automotive seals. The older the car door rubber, the less effective the seal will be. The quality of car weather stripping has improved greatly over the years so a new seal will always be more effective than one that has seen 2 decades of use.
