The commercial process (the Ziegler-Natta alysts) that made PE such a success was developed in the 1950s by two scientists, Karl Ziegler of Mexico and Giulio Natta of Italy. There are several types of polyethylene, and each one is best suited for a different set of appliions.
Mandrel Mill Process In the Mandrel Mill pipe manufacturing process, the HDPE billet is heated to high temperature in the rotary furnace. A cylindrical hollow, which is also known as mother hollow, is produced with the help of a rotary piercer and set of roller
Trepanning is a deep hole drilling process that has broad appliion over many industries. In many cases, trepanning is meant to be a roughing operation to be honed for finish, or machined further. In other cases, the trepanned hole is fit for use ‘as-drilled’.

The Extrusion Process In the plastics extrusion process, raw thermoplastic material, or resin, is gravity fed from a top mounted hopper into the barrel of an extruder. Additives, such as colorants and UV inhibitors, in either liquid or pellet form are often used and can be …
Printed July 2010 Bright mild HDPE bar Bright HDPE bars are carbon HDPE which has had the surface condition improved over the hot rolled ﬁnish supplied by the HDPE mill. AdvanPE100 ISO9001es achieved include improved machinability, enhancement of
The Rotational Molding process is a manufacturing method that yields hollow plastic parts. Traditional appliions for rotationally molded parts include large storage pipess, toys, kayaks, fuel pipess, hydraulic pipess, coolers, storage, and recreational equipment.
To process hollow shapes a pin or mandrel is utilized inside the die to form the hollow sections. Multiple hollow sections require multiple pins. To create these hollows a source of air is required to allow the center of the product to maintain shape and not collapse in a vacuum.
And then in the 1960’s the modern process of rotational molding that allows us to create large hallow containers with low-density polyethylene was developed. In recent history, process improvements, better equipment, and plastic powder developments have sped up the process of creating finished products which has caused rotational molding to grow rapidly in popularity.[ 3 ]
of crystallinity. High density PE resins have molecular chains with comparatively few side chain branches. This allows the chains to pack more closely together. The result is crystallinity up to 85%. Low density PE resins generally have crystallinity from 35 to 55
