Since 1946, Listo Corporation has provided high quality, plastic injection molding services. We are geared to accommodate both long and short runs. We specialize in problem solving and working with molds that are difficult to process. Listo is a captive shop. We produce our own product line. Who does this help? The answer is that it helps you, our future customer. With a product line to support the majority of our overhead, we are able to offer very competitive pricing to our custom injection molding customers. Molders who do not have their own product line have to amortize those costs ( machine, maintenance, and labor ) and pass them along to you. At Listo, those costs are absorbed by our own products, which will allow us to bid your projects at a low price. Each mold, sometimes referred to a tool, is built to exact specifications of the part or parts required by you. These tools need to be designed by a product engineer. We come into the process once the tool is built. We then take the tool, set it up in one of our 6 molding machines, and produce the parts. One the tool is in the machine, heat and pressure is used to inject the plastic into the mold, filling out all of the cavities that form your specific part. After a short period, usually around 30 seconds, the mold is opened, and the part is ejected. This process is then repeated.
