Glossary

  • ARM – Association of rotational molding – organization for roto-molders to network, share ideas and improve practices, procedures and policies.  See History of TerraCast.

 

  • Bollards – Short posts, often topped with lights, used as pathway illumination or as perimeter markers or barriers to keep vehicles from crossing into pedestrian areas, also used for landscape lighting.

 

  • Clamshell molds – A reverse casting of the final product, into which the resin is poured. All molds for rotational molding are made this way. The exterior cast makes the item inside. The product is made from the outside in.

 

  • Color blends – All of TerraCast®’s colors are uniquely blended to our specifications. Our ability to custom blend with dye added to make our proprietary color, is one of the unique traits that give us individuality in the marketplace.  See Technology of Textures.

 

  • Commercial grade planters – Much larger than what is found at a home improvement or hardware store. Suited for outdoor applications such as barrier between pedestrian and vehicular areas, while serving as beautification for streets, pathways, intersections, city architecture, and so on.

 

  • Garland – Describes the floral scrolling vines-and-grapes design often seen on traditional pottery and other decorations.

 

  • Granite colors/textures – Appearance of stone, like granite, speculate added for depth and variation.

 

  • Interior-scaping – Design, decoration and appointment of an indoors space, like a lobby, mezzanine or common area.

 

  • LED – Light Emitting Diode, a type of light bulb that outlasts incandescent and filament style bulbs. LED bulbs generate much less heat than halogen, incandescent or filament bulbs. Some can last as long as ten years. Often used for Christmas lights, but also found in remote controls, watches, computers, traffic lights, and so on. Most well known for their energy efficiency and longevity.

 

  • Linear low density polyethylene – A type of plastic specifically designed for use in widely varied commercial applications, from packaging, trash cans, park slides, and more. Rugged and durable, made to withstand the elements.

 

  • LTL – “Less than truckload” Term for shipping palletized items on a truck that is selling its extra available space. The LTL truck heading to a certain destination sells its extra space and adds a fee for delivery of your item to its destination, which in the direction of, or on the way to, the LTL truck’s final destination.

 

  • Luminaire – Decorative housing light fixture.  See Luminaires.

 

  • Machined – The way mold is made, aluminum is machined to build a mold.

 

  • Mold indexing – Machine arms in a roto-molding factory change between the three production cycles: filling, cooking, cooling.

 

  • Mold-in graphics – Custom graphic is built or applied to the inside of the mold; therefore, graphic is built into the design of the item during molding.

 

  • Mold-on graphics – Post mold application, graphic heated onto already-made piece.

 

  • Molds – Planters and roto-molded items are made in a mold, like a shell, which we use to replicate our products.

 

  • Non-hydroscopic – Does not accept, absorb or retain moisture.

 

  • Non-porous – Does not have pores. Not permeable by air, moisture, etc. Impermeable.

 

  • Porosity – Having become porous. Used to describe aluminum or metal where moisture has eaten away at the metal, causing tiny holes, pockmarks, or pores, which transfer onto molded castings as imperfections, tiny dots.

 

  • Resin – A type of plastic composed of polyethylene, or similar material. Not to be confused with organic resin, which is basically tree sap. TerraCast® uses linear low density polyethylene.

 

  • Rolled rim – Name given to the style of rim which has a round lip coming up and rolls over the circular top of the planter.

 

  • Roto-molding/rotational molding – Hollow clamshell mold is filled with a shot weight of resin, sealed shut for cooking. Machine arms rotate the mold on two perpendicular axes in an oven. The melted Resin disperses and paints into the mold, and the consistent rotation maintains even thickness in the oven and in the cooling chamber.

 

  • Self watering – Additional product TerraCast® offers for planters. Has a reservoir and a water wicking system so the plants can draw up the moisture from the reservoir, watering themselves.  See Self-Watering Planters.

 

  • Shot peen – The finish given to the inside of a mold, giving a “goosebumps” texture.

 

  • Squared rim – Name given to the style of rim that is squared off: all corners come to a point and make a 90-degree edge that drops over from the top, inside & outside the top of the planter.

 

  • Textured – The final visual output of the surface of our products.

 

  • UV inhibitors – Additives blended into the resin, which protects product from harmful UV rays, like sunscreen. TerraCast® uses UV12, which gives about 12 years of protection against bleaching or fading in the sunlight.
