Toshiba, M.R. Molds target liquid silicone
Toshiba Machine Corp. said liquid silicone molders now can produce multicolor products using a single barrel, using a technology jointly developed by Toshiba and M.R. Mold & Engineering Corp. of Brea, Calif.
The technology is available exclusively on Toshiba's EC-NII all-electric injection molding machine. A key part of the process is the V-30 controller to monitor each step of the process precisely, and specially designed molds from M.R. Mold that assure the colors are applied accurately, without gaps or bleed-through.

Hot-fill applications use aluminum mold
Groupe Sidel has announced a breakthrough: using aluminum molds in hot-fill blow molding.
Aluminum is an alternative to traditional stainless-steel molds in heat-resistant blow molding. The F300 aluminum mold can withstand temperatures as high as 325°F, so it can make PET bottles suitable for hot-filling or pasteurization, Sidel said.
Aluminum molds can be machined two weeks faster than stainless-steel molds, according to the company. Also, a lighter mold means less weight to move on the machine. It also reduces the time to change bottle shapes.
Sidel of Le Havre, France, developed and tested the mold with Graham Packaging Co. LP. Graham of York, Pa., is using more than 100 of the F300 aluminum molds at several of its U.S. plants.
Sidel is a major maker of blow molds, with two mold plants in France, one in Shanghai and one at Sidel Inc. in Norcross, Ga.
In other news, Sidel:
* Together with Systech Instruments Ltd. of Oxon, England, rolled out the Systech 8700, which analyzes the oxygen transmission rate of bottles treated with Sidel's Actis internal plasma coating technology. The unit is designed to meet the high output of Sidel's Actis 48 machine.
* Unveiled the fastest Combi blow molding machine, which can produce 61,200 bottles an hour.

Hot-runner package features 3-D drawing
Husky Injection Molding Systems Ltd. has launched a comprehensive three-dimensional customer drawing package for hot runners.
The package allows customers to easily check the tooling interface with the hot runner. It makes it easy to design interface details of molds without the hot runner.
For complete hot halves with plates, the package includes plate models with all features, manifold models with critical surface features, a unified nozzle stack and inverse gate detail that can be subtracted easily from your plates to save significant time in plate layout and design.
For manifold systems, it includes manifold model, a unified nozzle stack, inverse manifold pocket and inverse gate detail.
Husky is in Bolton, Ontario.

Flat die maker EDI motorizes deckle
Flat die maker Extrusion Dies Industries LLC's a new, motorized dual deckle - with a spring-loaded external segment - lets extrusion coating processors automate width changes, increase the precision of deckle settings, reduce or eliminate manual adjustment and cut downtime between job changeovers.
A deckle is a mechanism that varies the width of the web by blocking off portions of the flow at either end of a flat die.
An alternating current motor drives the external deckle, together with the primary internal deckle as a single unit. A smaller motor drives a secondary internal deckle that fine-tunes the flow at either end of the die, to minimize the formation of edge bead. Motorizing the deckle makes it possible to run the deckle as part of a computerized processing system.
EDI in Chippewa Falls, Wis., also has replaced the standard manual fastener adjustments for the external deckle, with a spring-loaded device that provides constant pressure at the die lips, permitting width changes with little or no manual adjustment.

Battenfeld presses add 650-tonne HM
Battenfeld Kunststoffmaschinen GmbH has expanded its line of HM hydraulic two-platen injection molding machines, by introducing an HM with 650 metric tons of clamping force.
HM presses boast low energy consumption, quiet operation and a low-maintenance design.
Four symmetrically positioned clamping cylinders combine with external fast-stroke cylinders, and a centrally located ejector. The result: symmetrical force transmission and fast, even clamping-force buildup.
In other news, Battenfeld has introduced EcoPower, designed specially to reduce the reactive power load for injection molding machines. On injection presses, power demand cycles from big demand to low consumption and back, putting an extra load on the utility's power grid.
EcoPower uses compensation units in different numbers, depending on the size of the drive. The system reduces both reactive power and effective power. It can be retrofitted onto existing injection presses, or ordered on new ones.
In other news, 150 visitors attended Battenfeld's Aquamould/Airmould symposium on water-assisted injection molding, held in June at the company's sales office in Meinerzhagen, Germany.
Battenfeld's U.S. unit, Battenfeld of America Inc., is in South Elgin, Ill.

Compact hybrid molds auto, electronic parts
Nissei Plastic Industrial Co. Ltd. has debuted a compact vertical injection press, the ST20-2V, with 22 tons of clamping force.
The hybrid press is designed for molding automotive parts and electronic components. It is based on the ST series of hydraulic vertical presses, which incorporate Nissei's X-Pump.
The press achieves 40 percent energy savings, with twice the response time, compared with Nissei's hydraulic vertical presses. Injection speed can be controlled in a stable manner in ultraslow speeds. It is 1.3 times faster than Nissei hydraulic vertical presses.
The tie-barless clamping mechanism is well-suited to insert molding. Nagano, Japan-based Nissei's U.S. unit, Nissei America Inc. is in Anaheim, Calif.

Inkcups pad printer handles large parts
Inkcups Now Corp. of Danvers, Mass., has introduced a large-parts pad-printing machine.
The ICN-150 handles 150-millimeter (6-inch) ink cups, which enables printed images up to 140mm in diameter. Its independent pad/ink cup stroke allows easy loading of large parts and fine-tuning of the print cycle.
In other news, Inkcups Now said two of its Sapphire product lines, the MB and J3 series, have been certified in Class 6 and approved for use in the medical device and diagnostic industry.
Inkcups Now also said its new computer-to-plate laser and printing plate maker, the Cobalt 350, makes plates for pad printing and is a versatile industrial laser etcher. The laser has very small spot size, and a variety of raster programs, controlling the quality of the printed images and laser-etched graphics.
The XY motion of the laser print head allows the machine to print very large images, measuring up to 25 inches by 18 inches.
By installing the Cobalt software to a standard personal computer, you can begin printing images to the Cobalt 350 laser.
