Rotomolded Tilt Trucks are Durable

Rotational molding, known as rotomolding or rotational casting, is one of the fastest growing plastics processing methods today. It’s easy to see why. Rotational molding techniques – coupled with Microthene® polyolefin powders from LyondellBasell can be used to make hollow items of any size, open or closed, and of any desired shape. In recent years, rotomolding techniques have been developed extensively.

Since 1997, Web Tex Tilt Trucks Parts & Accessories have proudly manufactured and assembled their Tilt Trucks in North Texas.  With a powder coated welded steel frame; they are designed tough for both the interior demolition and construction industries.

Web Tex Tilt Trucks outperform blow molding, injection molding and thermoforming. Other companies that usually use these types of molding techniques create a much cheaper product, but their equipment cannot stand up to the rigorous uses that are needed from commercial tilt trucks.

Rotational molding was first developed early in the 20th century. But it wasn’t until the early 1960s, when LyondellBasell replaced vinyl plastisol resins with polyolefin resins, that rotomolding gained wide acceptance. Within a few years, the development of low and high density polyethylene specifically designed for rotomolding enabled rotational molders to enter markets where vinyl parts and processes could not compete. In the early 1970s, cross-linkable and modified polyethylene grades made their way into the rotational molding market. These new resins again opened up more new market areas, especially production of large tanks. Linear low density polyethylene for rotomolding was developed in the late 1970s, while the 1980s brought a surge of non-polyethylene resins, including nylon, polypropylene and polycarbonate for rotomolding.

All Web Tex Tilt Trucks are made from 100% recycled plastics to help do our part for the environment.

The main difference between rotational molding and other plastics molding techniques, such as blow and injection molding, are as follows:

·         resin powder is used instead of pellets;

·         the resin melts in the molds instead of being forced under pressure into the molds in a molten state;

·         the mold has a biaxial rotation;

·         rotomolding molds are less expensive because of their simplicity;

·         and operating pressures are relatively low, allowing molds to be made from less expensive materials.

 

In rotational molding, rigid, resilient hollow bodies are formed by powdered plastic material in heated molds, which are rotated simultaneously in two planes perpendicular to each other.  The plastic particles make contact and melt on the inner surfaces of the hot molds and fuse in layers until all the powder is fused and the desired end product and wall thickness is obtained.  The wall thickness is controlled by the amount of powder placed in the mold.

Rotationally molded pieces are stress-free except for slight shrinkage forces because the pieces are produced without any external pressure.  Additionally, there is practically no scrap in rotational molding. The uniformity of wall thickness can be maintained to within ±10 percent, which is better than that normally possible with the blow molding process. Wall thicknesses can range from 1/32 inch to 1 inch (0.8mm to 25mm). Most resins used in rotational molding are powders ground to 35 mesh and ranging in diameter from 74 microns to 2000 microns.
