hdpe mortarsHdpe Mortars For Fireworks

Oxford Plastics manufactures hdpe mortars for launching tubes at fireworks shows. As a manufacturer of firework mortar tubes, we are currently looking for mortar distributors throughout North America, with a minimum order in the neighborhood of 25,000 lbs of material for it to be a viable production run. Used for launching shells and mines, or for creating mine racks, these launching tubes are usually anywhere from 1.875 to 6 inch diameter pipes that are about 2 feet long. Used by firework companies to produce spectacular shows at festivals, national holidays and other memorable events, these tubes are tough, lightweight and easy to use.

How Firework Mortars Work
Fireworks are launched from rows of steel tubes secured in troughs of sand. The tubes, or mortars, are three times as long as the firework shells but have the same diameter. If a shell or mine doesn't fit snugly into its launch tube, the pressure created by the lift charge will escape, and the firework can misfire.

Used primarily for creating aerial fireworks, a shell or mine consists of four parts:

  1. Container - a pasted paper and string formed into a cylinder.
  2. Stars - spheres, cubes or cylinders of a sparkler-like composition.
  3. Bursting charge - firecracker charge at the center of the shell.
  4. Fuse - provides a time delay so the shell explodes at the right altitude.

The shell is launched from a mortar. The mortar can be a short, plastic, paper (or heavy wall cardboard) or steel pipe with a lifting charge of black powder that explodes in the pipe to launch the shell. When the lifting charge fires to launch the shell, it lights the shell's fuse. The shell's fuse burns while the shell rises to its correct altitude, and then ignites the bursting charge so it explodes.

Features
We offer hdpe mortars, type DR-11, in diameters from 1 7/8 (1.875") to 6 inches which are capable of holding any 1.4 g consumer shell or mine.

Advantages of using Hdpe Mortars
In the past fireworks have been launched from everything from paper tubes to rows of steel or plastic tubes called mortars. Hdpe mortars, however, offer unexpected advantages that plastic, paper and steel pipe cannot. Unlike most plastic pipes, i.e., pvc or abs tubes which are incredibly brittle, hdpe pipe is much stronger and capable of handling any shell malfunctions. Steel or metal pipes are still used to launch very large shells, i.e., around 12" and up, but unlike hdpe pipe, they are extremely heavy and hard to handle. They're not used very often anymore for smaller shells simply because of their weight. And while paper mortars may still be in use for the hobbist,
hdpe mortars can be used to launch shells thousands of times giving you much more for your money.

Applications
Hdpe pipe can be used in a variety of ways to launch firework devices. You can use these tubes to construct your own firework mortars or mine racks. Our tubes are size DR-11, with an exact ID of 1 7/8" (1.875"), which are capable for holding any 1.4 g consumer shell or mine. Hdpe mortars are perfect for launching shells, mines and many other pyrotechnic devices.
