Blade forming gives good formation but retention suffers due to the sharp pressure pulses of the blades.
Modern twin-wire machines use roll forming to initially drain the sheet and form a mat.
Top-wire formers are also still evolving based on better understanding of the forming process, and rebuilding of older top-wire units is a good way to improve their overall operation.
Describing enhanced single-station, sheet-fed forming systems featuring fast-set-up and turbo-cooling.
Supplies roll-fed, trim-in-place, servo-driven, plug-assist forming equipment for polyolefin packaging.
Supplier of in-line, roll-fed forming equipment plans to display new dual-mold machine for PP packaging.
Each machine comes programmed with detailed graphical drawings of the machine, a listing of general process parameters, and step-by-step instructions on how to set up and operate the machine for 13 different thermoforming processes, such as drape forming
, billow forming
, or straight vacuum forming
The new SF series servo-driven pressure former, designed primarily for forming blister packs or trays, will be exhibited by Zed Industries Inc.
Both it and a second model (KMD52 BFS) have a redesigned servo-drive system for material indexing, forming, trimming, and upstacking, and--for the first time--plug assist.
It comes in three sizes with forming areas from 27 x 32 in.
is another relatively new name in forming equipment.
Vandalia, Ohio, will introduce three in-line forming systems:
forming area, and computer control with recipe storage and touchscreen color monitor.
Pressure forming offers an advantage of flexibility to a customer with a new high-tech product, even when the product is ultimately expected to sell 100,000 units.
deep) pressure formed by Arrem for a blood-chemistry analyzer might have been $750,000 to $1 million with injection molding, but only 20% of that for pressure forming, says Arrem.
