The solid resin is introduced into the hopper and, through the action of the rotating screw, is conveyed into the heated barrel. The screw in this section is feeding or conveying the solids and, hence, is quite deep. The geometry of the screw is such that the depth decreases in the transition zone, and the solids start to melt. Melting results from the shearing action of the screw as motor horsepower is converted into frictional heat. Barrel heaters are used for start up and to supplement the melting process. The melt continues to be pumped toward the discharge, or die end, of the extruder through the metering section of the screw. Metering is pumping at a given rate in a uniform manner, within close temperature and pressure tolerances.

CONVENTIONAL SCREW
• FEED SECTION – Solids conveying, some compaction and little heating • BEGINNING OF TRANSITION – Resin heated and compressed • TRANSITION 1 – More melting and more compression. Melt pool formed • TRANSITION 2 – Melting continues, shear rate increases, melt pool increases and
solids bed decreases • METERING 1 – Only less efficient melting occurs. Unmelted pellets distributed in
melt pool • METERING 2 – Non-uniform melt with viscosity and temperature gradients

BARRIER SCREW
• FEED – conveys solids, little melting and some compaction • TRANSITION 1 – A second flight is started, called barrier flight to separate solid
and melt channels • TRANSITION 2 – Melting continues as solid pressed and sheared against barrel
and melt collected in melt channel • Melt channel is deep, giving low shear and reducing overheating of melt. Solid
channel becomes shallower, giving efficient frictional melting • Solid bed continues to get shallower and finally disappears • All resin is melted uniformly

Parison wall thickness control is usually brought about by the raising or the lowering of a mandrel within the die ring to give a controllable variation in the mandrel/die clearance. The mandrel is actuated by hydraulic, pneumatic, or mechanical means. The thickness control movement is programmed to operate with each parison production cycle. Parison produced using wall thickness control, sometimes called differential parison extrusion, have a constant outside diameter, but with stepped variation of wall thickness to cater not only for draw-down and die swell effects, but also to give the blown article a constant wall thickness, irrespective of their final form.
Parison Wall Thickness Control
![Page 28: VINAY AGARWAL CREATIVE PLASTICS · 185 Zaveri Bazar, Bank of India Bldg., 3rd Floor, Mumbai 400 002 Tel: +91-22-2344 3354/23443207 Fax: +91-22-23412922 Email: vagarwal@vsnl.com VINAY](https://reader034.vdocuments.us/reader034/viewer/2022050114/5f4b20bd4884d87386197b02/html5/thumbnails/28.jpg)
Effect of Parison Programmer on Parison Thickness and Bottle Wall Thickness
A parison programmer is a device that can change the gap between the die and mandrel while the parison is extruded. The wall of the parison is ringed with sections of thinner and thicker material. These rings are located to correspond to specific sections of the bottle. For many blow-molded articles, parison programming can reduce article weight and cost, and improve quality, performance, and strength.

Advantages of PP
Recent Breakthroughs in PP resins & Stretch Blow Technology have made PP more appealing and cost competitive versus PET “Practical” clarity of PP is equivalent to PET Excellent moisture barrier Excellent balance of stiffness, impact strength, heat resistance and chemical resistance Hot-fill performance Micro-wave able Retort sterilizability

Economics of OPP versus PET
Conversion Cost
With Recent Breakthroughs in PP preform designs, resins, additives and ISBM process, PP could be processed at same rate as PET
No drying needed for PP (lower energy cost)
PP could be processed on PET equipment with minor modifications
Same/Lower Conversion cost for PP vs. PET

Stack Molds
In this type of mold the mold cavities are placed one behind the other instead of side by side. Stack molds only need a clamp force sufficient for one “stack” of molds. Their major drawback is the difficulty in getting plastic through the stack to all the cavities.
