Italy's Caccia works rotomolding `Magic'
Italy's Caccia Engineering SpA says it has invented a faster, more customized way to make rotational molding machines. Call it ... Magic.
Caccia claims it can deliver a machine in four to six weeks, using the patented Magic system. "We believe [we] have made the dream of rotomolders ... come true: availability of mass-produced machines and therefore with low costs, with the capacity of meeting the different requirements of each single molder," said company literature.
It works like Tinker Toys. By building with lengths of tubular steel and quick-assembly panels, Caccia said it can build each Magic rotomolder to the exact size the customer wants.
The dimension is determined by the length of the tubes. Pre-fabricated panels are used for the oven and cooling chamber, and Caccia has developed a standard fastening system to hook the panels to the tubular structure.
For the cooling chamber, Caccia offers a choice of materials for the inside, including steel, stainless steel and aluminum. Damaged doors can be replaced easily.
The company uses folding doors to save space and improve safety.
Caccia of Samarate, Italy, first built a prototype shuttle machine. The company then built an independent-arm rotary machine with a 138-inch swing.
Other recent innovations include a gravimetric mold-feeding system that uses bar codes, an electronic mold-balancing system and remote diagnostics.
In the United States, Caccia is represented by EAP Machinery Systems Ltd. of Erie, Pa.

Gloucester now has horizontal hauloff
Battenfeld Gloucester Engineering Co. Inc. has introduced a horizontal oscillating hauloff for blown film.
The horizontal unit complements the company's vertical design of oscillating hauloff, called Traversanip. One key difference, according to the company, is that each design takes its own approach to randomizing gauge banding of the finished rolls.
The vertical hauloff provides random banding for all applications, but some customers prefer a horizontal design, according to officials of the company in Gloucester, Mass.
On the horizontal unit, the mechanism that controls the rotation of the air-turning bars permits them to rotate freely when the unit is in the thread-up mode. The device locks the bars when the oscillating movement starts or the line reaches a certain speed.
The interior construction of the turning bars assures uniform distribution of air along the entire length of the bar. An optional configuration allows the unit to run sticky adhesive films by floating the film on an air cushion so it does not touch the turning bars.

Speedex delivers machine to Thailand
England's Speedex Designs Ltd. has delivered one its largest caterpillar take-off machines to a polyethylene pipe maker in Thailand, Wiik & Hoeglund Public Co. Ltd.
Speedex said Wiik & Hoeglund, a subsidiary of Finland's KWH Pipe Ltd., is the largest maker of high density PE pipe in Asia.
Each chain conveyor on one of the CT/1600 take-off machines is driven by its own digitally controlled AC drive, so the machine can run at an infinitely variable speed range, up to 40 inches a minute.
Speedex Designs was formed after IMH Group Ltd. bought the intellectual property of the closed-down Speedex (Engineering) Ltd. The business now is based at IMH Group's factory in Wakefield, England.

Inspection system designed for sheet
Lasor Systronics of Norcross, Ga., has developed the 2f1 vision inspection system for sheet and rigid film. For plastic sheet, the firm can add stress and thickness measurement capabilities.
Lasor Systronics also makes the SVS vision system, which detects gels, pinholes, carbon specks, streaks and wrinkles.

Pressure controller monitors 2 channels
Dynisco Instruments said its CPC832 cavity-pressure controller for injection molding can monitor two channels of pressure in mold cavities, or one pressure in the mold and the hydraulic pressure.
The menu-driven, touch-screen control is easy to use, said Dynisco Instruments of Franklin, Mass. The machine operator gets a graphic profile of each shot, superimposed over a profile of a good part.
The operator also can plug in threshold settings so the machine automatically rejects parts that are under filled or over filled.
