Planet Earth is spinning at a rate of 0.0007 rpm. Easy to calculate: One revolution per day, divided by 24 to get revs/hr and then by 60 to get revs/min = rpm. As for linear speed, it depends on where ...

Extrusion is a process used for creating a product (an extrudate) by forcing a material through a die or an orifice to form a shape, or alternatively an extruder is used to produce semi-finished or ...

I teach a one-day Intro to Extrusion seminar, and many of my participants are new to extrusion. Therefore, I explain the basic principles of screws for thermoplastics. That’s good for the newbies, but ...

A lot of great ideas happen in the middle of the night, and for [Werner] it’s no different. One night he came up with an idea for a new 3D printer extruder, and after a very basic prototype, we’d have ...

Convertible extruder transitions from a 3-inch smooth feed to a 60mm grooved feed type featuring low-boy design for blown film, ability to swing between resin types and fast changes between feed ...

Extrusion equipment suppliers strive to meet new needs of the marketplace. While they continue upgrading speed, output and quality, they're also offering solutions to emerging demands in bioresin ...

Leistritz has added a continuous twin screw extrusion system that continuously mixes and conditions gel-mass formulations designed to replace previous upstream batch processing methodologies.

There are many industrial applications requiring linear motion, and for most applications, conventional belt or screw drives do just fine. But when loads need to move long distances (more than 40 ft), ...
