Injection velocity is one of the critical parameters in a molding process. Set the speed to incorrectly and there are many defects you can get such as flow marks, jetting, dieseling and weld lines. However if you optimize the velocity, your material viscosity can be consistent shot to shot and you are on the path […]

Determining an optimized Injection Molding Process is often an overlooked part of getting a product up and running. Getting the process right the first time however can save a lot of headache down the road. The first step to an optimized process is getting the Injection Velocity right. Many materials come with recommended settings which […]
Use Multiple Materials The injection molding process can be used with numerous different materials. There are hundreds of plastic materials that can be used on their own each with different properties and purposes. There are additives to change the properties such as strength or uv resistance. Two or more different materials can even be molded […]
Have you ever had a scenario where you are trying to troubleshoot a problem where a part periodically goes short, or a surface randomly seems shiny? Chances are your hold time is to short, or right on the edge of the gate freeze time. If the gate of a part is not frozen before the […]
