Husky, Nano develop molding equipment
Husky Injection Molding Systems Inc., working with Nano Scale Surface Systems Inc., has introduced injection molding equipment to produce plastic medical disposables with an internal barrier coating of silicon dioxide.
The equipment makes parts with glasslike properties, providing a barrier against gas transfer and preventing a chemical reaction between fluids and the plastic parts.
Husky of Bolton, Ontario, said the plastic parts can replace many items now made of glass, including test tubes and blood vials, eliminating the risk for breakage and injury.
Husky displayed the parts at the Plastec West trade show, which was held Feb. 13-15 in Anaheim, Calif.

Firm's molding helps hooks fit on car liner
Aplix Automotive Group in Southfield, Mich., has developed a technology called inter-mold for molding in hooks on car headliners, instead of using the labor-intensive insert molding process.
Inter-mold does not require fasteners to be inserted into the mold before injection. The hooks are formed simultaneously during molding.
Aplix said the field of hooks can be any shape or size, in virtually any location on the part. The method works with many polymers, including polypropylene, polyethylene, nylon, acetal and thermoplastic elastomers.
Inter-mold is being used for headliner attachment brackets on the 2007 Ford Edge and Lincoln MKX.

Cage System adapts for plastics injection
RocTool SAS of Le-Bourget-du-Lac, France, known for using electromagnetic induction to process composites, with Visteon Corp. has adapted Cage System technology to the plastics injection molding arena.
Injection molding by induction can be applied to thin or overmolded parts, any type of cosmetic part and materials with strong viscosity, such as elastomers.
Visteon worked with RocTool for three years to adapt the process to injection molding as a way to improve quality and reduce costs.
Traditional injection molding requires high injection speed and a lot of pressure to fill the cold mold, as the plastic starts to solidify during the shot. That can cause molded-in stresses, making it hard to make flat parts.
As an alternative, the RocTool method uses electromagnetic induction to heat the surface of the mold quickly - in five to 10 seconds - so the mold is close to the temperature of the liquid plastic.
Molders can optimize the thickness of the part, cutting weight, the company said.
Alex Guichard, chief executive of RocTool, said the company is developing two tools equipped with the technology to be installed in France by the end of this year. RocTool said it wants to license the Cage System to resin makers and processors.

Polar-Form adds 2nd Ferromatik machine
Polar-Form Werkzeugbau GmbH of Lahr, Germany, has added a second multicomponent injection molding machine from Ferromatik Milacron Maschinenbau GmbH.
The K-Tec 275-2F joins a K-Tec 155-2f at Polar-Form's technical center, which opened in 2001.
The 275-2F has a clamping force of 275 metric tons and features an enlarged mold-installation area so Polar-Form can test and approve larger molds. The tooling company also can do special projects that combine multicomponent and in-mold labeling.
Ferromatik Milacron in Malterdingen, Germany, is a unit of Cincinnati-based Milacron Inc.

New Weima shredder handles bulky items
Weima America Inc. of Fort Mill, S.C., has introduced a new version of its WLK 12 single-shaft shredder for shredding bulky plastic containers and other thin-wall parts, such as totes, barrels, drums and tanks.
The compact machine includes a new press-down device so the customer can shred even very large totes without the need to precut.
The shredder is equipped with a doghouse-design hopper that is open over the top of the rotor. Whole pieces are directly loaded into the front of the machine. After loading, the press-down device pushes the material to the bottom of the shredder. A horizontal ram pushes it into the rotor, parallel to the down stroke of the press-down device.
Weima said electronic controls run both types of pressing action by reading the amperage load on the main motor and optimizing pressure applied to the rotor.
The working width of the WLK 12 is 47.2 inches.

Nissei supplements hybrid press series
Nissei Plastic Industrial Co. Ltd. has added three new midsize injection molding machines to its Hybrid FNX series, which combines electric and hydraulic power.
The new FNX sizes include a 242-ton 220-50A and 220-71A, the 308-ton 280-71A and 280-100A, and the 396-ton 360-100A and 360-140A.
Last year, the Japan Machinery Federation gave Nissei's hybrid machine the Director General of the Agency of Natural Resources and Energy Award.
The key to the FNX series is what Nissei calls the X-Pump, a hybrid pump that combines the servomotor and hydraulic technologies as the driving source of the press.
The servomotor only delivers power to the pump when it is needed, and stops when no power is required.
Nissei of Nagano, Japan, claims the 396-ton Hybrid FNX consumes 55 percent less energy than hydraulic machines.
The machinery maker's U.S. operation, Nissei America Inc., is based in Anaheim, Calif.
