hi everybody! i am involved in designing a extruder capable of receive plastic material of both black core and yellow sheath from two chambers and heat them and syncronizedly extrude themand cut them in lengh automaticaly . can anybody help me and give me any means of advise?
RE: plastic pencil extruding machine extruding core and sheath together
You need to develop a coextrusion process using two extruders. There are a variety of methods of making the two layers, which I assume are concentric. Since you intend to cut to length in this operation can I also assume that these are thermoplastic resins as opposed to thermoset? If you can furnish a little more information, such as estimated lbs/hr(kg/hr) and size of the finished extrudate inches(mm) I can be more helpful in specifying some proposed equipment and typical production processes.
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines.

This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.
