Injection Molding
Started by Dan Brown in 1999, ATP is a injection molding company that specializes in low to high production and test specimen applications. Our 40+ years of experience in injection mold manufacturing allows ATP to focus on what we excel at; product quality, low cost pricing strategies, decreasing lead times, and lean manufacturing.
How Does Plastic Injection Molding Work?
Our injection molding process at American Test Plaque (ATP) is a standard process involving common plaque inventory or customized aluminum and steel molds. Our process monitors fill pressure, temperature, timing, and the quality of the parts during all phases of the molding cycle.
The injection molding process starts by pouring resin pellets into a barrel where they will eventually be heated until melted, compressed, and injected into the mold. The heated resin is then forced into the mold cavity through the gates within the mold and and the part is molded within the mold. When the mold cavity is built, they add ejector pins that help with the removal of the part from the mold after the resin as been forced into the cavity and cooled. When the resin has cooled the mold is separated apart and the ejector pins push the part out of the cavity and into a loading bin below.
