HIPF was host to the visit by HRH Sattam bin Saud bin Abdulaziz and delegates. He was accompa-nied by the TVTC Governor Dr. Ali bin Nasser Al-Ghafis. HRH was pleased with the standardsmaintained by HIPF. The visit by His Royal Highness shows that HIPF is making its effect felt in theSaudi Industry and in the training of its future workforce.
Presently trainees of HIPF are part of more than 60 companies across the Kingdom like Pet-
roRabigh, SABIC, SHARQ, SIPCHEM, TASNEE, YANSAB, Gulf Arabia, NAPCO, Obeikan,Rowad, Watania, etc. It is our aim to have HIPF trained employees in all the plastics industries of this
kingdom.
Aluminum mold for high-volumeinjection molding is now widely usedbecause of low cycle time, speed ofmold making and low making costs. Asuccessful molding with aluminum mold
can make the production 20% to 40%faster than the same part with a steelmold.
Until now, Aluminum mold wasconsidered soft that couldnt with-stand the high-temperature, high-volume injection molding. This problemis solved by using High-strength alumi-num alloys originally developed for air-craft applications.
At the start up of the productionthe mold temperature can be achieved
much faster than steel because of thesuperior thermal conductivity of alumi-num. This means not only that moreparts can be produced per shift, butalso machine downtime for moldchanges can be reduced. With greater
machine utilization, more parts can beproduced.
Since aluminum pulls the heatout of a part faster the part can beejected quickly. It also means that
mold can be filled faster with reducedshot time and lower injection pressure.Thus, the molder can save time at dif-ferent points of the molding cycle.
We see that aluminum moldsare less expensive, have lower energyexpense and need lesser clampingpressures. It has to be pointed out thatthe machine operators need to betrained before they use aluminummolds ast h e y
s h o u l dnot use itsimilar tos t e e lmolds.

3D Printing
3D printing is a modern technologythat turns computer design models toreal objects. This technology is all set torevolutionalize the manufacturing in-
dustry. Just as we take an original paperto be scanned and copied, we can takean original object and laser scan it to acomputer. This design or our own de-sign can then be used in a 3D printer to
make multiple copies. 3D printing is used tomake products smaller than a human hair (nanosize) to huge parts of buildings. Copies of com-
plex shapes of curves, bends, engine parts,mesh structures, tools and even interlinkingmovable chains are made just by printing them.
Different types of materials such aspaper, plasters, glass, ceramic, almost any
metal alloy (stainless steel, bronze, titanium,etc.), photopolymers, liquid resin, rubbery elas-tomers, thermoplastics like PS, PE, PP, ABS,
Nylon, Glass fiber reinforced nylon, PEEK, etc.can be used. Some companies even make edibleshapes from materials like sugar and chocolate.Products can be made by incorporating differ-ent materials like elastomers and plastics ofdifferent colors and compositions in the same
printed product.There are currently many technologies
used. In one of the popular techniques, each
particle of mate-rial is placed in its
planned positionand successive
layers are built upon it to get differ-ent shapes. Verythin layers of molten thermoplastics materialare placed over each other to obtain the final
product. For thermosets, a very thin layer ofliquid or power material is placed and the re-quired cross-section in each layer is hardenedand bonded together by fusing or cross-linking. The process is then repeated for manylayers to obtain the final product.
The plastics industry could make use
of the 3D printers to make prototypes of new
designs and products. This will highly reducethe considerable time and money consumption
for developing molds and dies for the proto-
types. . Different materials and shapes can first
be printed and tested so that only the product
which passes the application testing needs to
be developed. This technology will make the
development of new successful plastics prod-
ucts faster and cheaper.
pressure (< 6 bar) and at low tempera-ture (< 150C). No necessity of high-
pressure compressor and electric con-sumption is 2 to 3 times lower comparedto traditional blowing of preforms.
Roll N Blow 4 tracks thermo-forming machine manufactures up to7000 bottles / hour.
The Bottle Thermoforming machineRoll N Blow of Agami allows producing
bottles at a cost and a material weight muchlower than the conventional methods. It is
based on an innovative technology of tubularthermoforming from a plastic sheet in reel.This technology authorizes high and roundshapes for a volume from 100 to 500 ml. It
addresses fresh dairy products industry andmore particularly drinking yoghurts, and alsofruit juices. Numerous plastic materials arecompatible with the thermoforming (PS, PP,PLA, PET).
The production of a plastic filmextruded at high pace and large width is veryeconomic. The plastic goes directly fromstage of sheet to bottle. This represents sav-ings of purchase of the order of 30% to 50 %.The use of reels of plastic sheet as basic ma-terial allows to reduce the costs of transport,storages and manipulations of bottles or
empty preforms upstream to the blowing.In terms of utilities all the consumptions arereduced with regard to the conventional tech-nologies: the blowing is implemented at low-

Inject To Blow
P A G E 3V O L U M E 5 I S S U E 1
ENGEL AUSTRIA and CANTONI have de-veloped together the inject2blow method, whichcombines the injection molding and blow molding proc-esses in machine and significantly reduces time andcosts in the manufacture of cosmetic, drug, and foodcontainers.
Preforms normally have to be made using injec-tion molding first and then subjected to a second proc-ess on a blow molding machine before they become afinal product, but the new method allows small ready-to-use containers to be manufactured in one process. Thiscombination method is the first of its kind available on
the market and has a cycle time of less than 14 sec-onds for wide neck jars in a 4 cavity mold.
Other benefits of integrating the processes in-clude lower system investment costs, a smaller systemfootprint, higher system availability, simpler quality con-trol, and no maximum clamping force. The inject2blowmethod can be used to process a wide range of thermo-plastics like PE, PP, PET and PC.
The machines offer plenty of free space for thesliding table mould because their clamping unit doesnot have a tie bar. As the mould clamping platens of tie-bar-less machines can be used up to their edges or
even beyond, large moulds can fit on comparativelysmall injection molding machines. Machine size cantherefore now be decided according to the requiredclamping force instead of the size and movementradius of the mould, which keeps investment andoperating costs low. The barrier-free mould areaalso simplifies the automation process, because therobot can access the mould from the side withoutbeing hindered.
Preforms do not have to be heated up again
before the blow molding part of the process, andhydraulic ENGEL machines, match consumptionlevels achieved by fully electric machines. Hydraulicinjection molding machines equipped with the servo-hydraulic system ecodrive consume between 30%and 70% less energy than comparable machineswhich don't have this energy saving option, depend-ing on the specific machine and use. As the injec-t2blow process is based on standard injection mold-ing machines, the system can be used with moldsfor classic injection molding products too.

US$0.62 per farad.Dr Xie said: "Compared torechargeable batteries andsupercapacitors, the proprie-tary membrane allows forvery simple device configu-ration and low fabricationcost. Moreover, the per-formance of the membranesurpasses those of recharge-able batteries, such as lith-ium ion and lead-acid batter-ies, and supercapaci-tors." Hence this technology
may find use in automobile and in cell phones.The plastics industry in the Kingdom could get a great
benefit by making use of this innovation in developingnew products and capturing new markets.
