Using Pressure Transducers In Plastic Mold Making

Since the 1960's Plastic mold have use pressure transducers to monitor many different aspects of molding. Now, more and more injection mold makers are using pressure transducers to add value to their molds. As globalization and an uncertain economy take their toll on mold making, it makes sense to add high value to you finished product. Now that pressure transducers can be designed and installed in a greater variety of locations, with varying purposes, the applications are more robust than ever. Why use a pressure transducer? Using a pressure transducer enables mold makers to gain precise and accurate data about how the tool is actually performing in production. Some of the types of information that can be gained are: How different fill speeds affect the balance of the tool. 1.What kind of effect varying temperatures have on the final part. 2.How different cooling temperatures affect the outcome of the part. 3.To obtain accurate information when using slides and the effect of Rapid prototype mold pressure on the components. 4.To help with the design of a more robust core and cavity. Why not just use simulation software? A detailed comparison of simulated results with actual in-process data will quickly answer that question! Use pressure transducer information to help the customer A customer who has just spent many thousands of dollars will most likely benefit greatly from the precise and detailed information you can provide. Pressure sensors were rather delicate in the past, as well as difficult to install. Now, with the aid of solid modeling the model for pressure sensors can be electronically sent from the customer to the mold maker. This greatly helps to avoid the possiblity of a poor location or improper installation. Conclusion When used as a value added mold component, pressure transducers can help the mold maker to gain a competitive edge. With the increase of international competition, the trend toward more sophistication will continue and the use of pressure sensors is a good example of adding a valuable service to help the customer.
