preform

M2 PRESSWIRE-September 2, 2019-: Global and China Optical Fiber Preform Industry Report, 2019-2025

In the company's ASB series machines, the second station is used for preform conditioning--adjusting the temperature profile and/or shape of the preform before blowing in the third station.

The compact, ground-level Sidel EasyFEED preform feeder features aamodular approach.

At present, the Rouiba Algeria facility is equipped with 15 PET preform injection moulding machines enabling the production of 35 different preform shapes, eight types of bottlenecks and two types of caps.

With mass-produced packages wanting to look different, even preform molds are adding flexibility.

Unlike wasteful 2-step systems that need to fully cool and re-heat the preform, the 1.5-step process retains most of the heat from the injection moulding process for final blowing of the bottle.

The lightest preform in the range weighs just 13.6g and works well for individually embossed 250m1 and ribbed 330m1 bottles, and also for ultra lightweight 500m1 bottles for still water.

The process starts with injection molding of a tube-like "preform." The preform is stretched axially by a stretch rod and radially by pressurized air until it takes up the shape of the bottle mold.

The 2005 edition was intended to be just a design guide, but readers complained that it said little about the practical aspects of injecting molding PET (polyethylene terephthalate) preforms. Therefore, a new chapter on all aspects of preform molding has been added here.

With the ever-present challenge of ensuring high, consistent quality products, APPE turned to Intravis for its testing applications including a ColourWatcher system, which ensures preform colour consistency, PreWatcher, for high speed preform selection and BottleWatcher, for container inspection.
