Abstract
This study is based on the modification and development of a two-liter plastic container blow molding machine into a five-liter one provided with a translucent view stripe. This study considers some objectives including reducing the total cost, increasing the amount of plastic recovery, and raising the desired plastic materials. Proper designs were prepared and directly applied on spot. Tangible results were obtained. Among others, the modification of some components of the machine, e.g. the extruder, has led to the possible reuse of the milled (recovery) and extra material from the manufacturing processes. That was also conducive to an effective reduction in the cost of production to 50% in some cases. Prior to its modification, this old machine was used to produce polyvinyl chloride (PVC) containers that have become prohibited these days for their damaging effect on man’s life. For now, and after modification, it has become possible to use High Density Polyethylene (HDPE) material, a fact that has improved labor conditions, too.

Summary
The idea was that in stead of purchasing a costly new machine, the old one can be modified. A ring is used where the polymer being processed is heat sensitive and degradation may occur due to increased residence time at the inlet and outlet of the breaker plate. Another modification of this study relates generally to blow molding machines and more to a blow molding apparatus for producing a container with a translucent view stripe on the mold part line on the container. Plastic containers, such as motor oil containers, are generally made of an opaque colored plastic resin to provide product identification for consumers. This avoids the unusual look of having view stripes running through the top and bottom of the container where, in many cases, where such stripes were not available [10,11]
