Companies provide cap-molding system
A cooperative endeavor between Netstal Machinery Inc. and Marland Mold Inc. has provided a system to injection mold 128 caps simultaneously.
The two companies allied forces to provide molding systems for the caps and closures market, said Werner Christinger, president of Netstal Machinery in Fort Devens, Mass.
The system will use Netstal's SynErgy 4200 injection molding press and a Marland 128-cavity mold to produce tamper-evident, 28-millimeter-wide caps. A closure maker is using the system to produce the caps for an unidentified bottler in the eastern United States.
In a prototype demonstration at WPE, a Netstal machine ran a four-cavity Marland tool to produce 38mm closures.
The firms say the 128-cavity system is competitive with compression molded closures and other injection molding systems. The SynErgy press's accumulator hydraulic system permits standard parallel functions and high speeds in the toggle-clamping system, according to Dan Morris, Netstal director of sales and market development.
Marland uses a Netstal machine at its facility in Pittsfield, Mass., to run trials.
``We have always felt it is one of the fastest machines available, [and] it helps us sell our tools,'' Andy Edlund, Marland vice president of sales and marketing, said in a statement.
Netstal Machinery, incorporated in 1983, is a subsidiary of Nafels, Switzerland-based Netstal Maschinen AG.
Husky stakes refund on press performance
Husky Injection Molding Systems Ltd. has issued an unusual refund offer to debunk challenges to its dominance of the market for PET preform machines.
The Bolton, Ontario, company sells a majority of the world's machines in this market.
The firm is offering to refund US$100,000 to a customer if Husky is unable to demonstrate that its new G-series system outperforms any competitive system for the same operating conditions, according to a company release.
The conditions include mold cavitation, preform design and part quality. Michael Urquhart, vice president of service and sales, said a typical G-PET system will cost more than $1 million.
Husky said the ``G-PET machines equipped with their robots and Generation II molds will run one second faster than any competitive system in a head-to-head comparison under equivalent conditions.''
Husky's line of PET preform systems range from single-cavity prototypes to 96-cavity production units.
In December, Husky introduced its Moduline E-series two-platen machine, which eliminates the usual large clamp assembly and brings down both the cost and floor space needed for large-tonnage machines.
