plastic mold machines Hourly Rates Dipped

plastic mold machines Hourly Rates Dipped Custom injection molders’ machine-hour rates dipped 1.3% on average in the second quarter of the year, according to 122 plants responding to our latest semi-annual survey. Rates have been dropping since the end of 2000. About 12% of respondents said their rates were lower in the second quarter than in the quarter before. Only 5% raised rates, and 83% did not change them at all. However, there were some signs that business was turning the corner at midyear. Molders’ average machine capacity utilization rose about 1.5 percentage points to 53%—still very low by historical standards. Almost 40% of respondents said their capacity utilization increased in the second quarter, versus 31% whose utilization was lower and 29% whose utilization was un­changed. This was the first time since early 2000 that more shops were gaining business than were losing it. Southeastern molders again enjoyed the highest capacity utilization, while those in the West had th...

plastic 2 shot injection molding

Two-shot silicone-thermoplastic injection molding is a method to create a silicone-and-thermoplastic part in one process. These parts are traditionally plastic molding individually and assembled as one medical device component. The two-shot process eliminates secondary operations and assembly, which are often the main contributors to increasingly higher part costs. By reducing the chance of misalignments seen in traditional inserts or in overmolding processes, the two-shot process enables improved performance and consistent quality. The process offers the ability to produce complex mouldings from two different polymers at the same time during one machine cycle. Separate, but compatible, materials or colours are chemically bonded or mechanically interweaved during the forming process when the second material is injected into the mould, which avoids the need for further assembly or postprocessing. Alternatively, incompatible materials can be mechanically connected by two-shot moulding ...
