The apparatus further comprises a thermal conditioning device (11; 111; 211; 311; 411) configured to act on the dose (6; 106) while the dose (6; 106) is positioned in said at least one mould (5; 105; 205; 305; 405) and before the closed position is reached, by thermally conditioning at least one surface portion (20; 120) of the dose (6; 106) which is distinct from a resting portion (17; 117) of the dose (6; 106) which is resting on the receiving part.

An example method of forming a biodegradable component includes extruding a mixture of biodegradable material and water through a die. The method further includes dividing the extruded mixture to form a plurality of biodegradable pellets. The method further includes forming the plurality of biodegradable pellets into a component. The water acts as a binding agent to bind the plurality of biodegradable pellets to one another.

A fixed abrasive article having a body including abrasive particles contained within a bond material, the abrasive particles including shaped abrasive particles or elongated abrasive particles having an aspect ratio of length:width of at least 1.1:1, each of the shaped abrasive particles or elongated abrasive particles having a predetermined position or a predetermined three-axis orientation.

The present disclosure relates to a method for calibrating a stationary THz measuring device which measures geometric properties of a profile by means of one or more THz sensors during an extrusion of the profile, comprising at least one or more steps.

A method of making a flexible medical article or tube, for example, a sheath for a vascular access device, is provided. The method can include extruding a polymer, for example, a polycarbonate-urethane copolymer, to form a tube and annealing the extruded polymer. The method can further include cutting the extruded tube to a desired length before or after annealing, flaring one end of the annealed tube and over-molding the flared portion onto a hub, and forming the other end of the tube into a tip. A sheath formed by such a method is also provided.

A die-formed chamfered plastic floor and a preparation method thereof are disclosed. The method includes: mixing raw materials for preparing a plastic floor matrix to obtain a mixed material; subjecting the mixed material to an extrusion, a laminating-embossing treatment, a die forming-chamfering treatment, a coating with an ultraviolet curable paint, a slicing, and a tenoning in sequence, to obtain the die-formed chamfered plastic floor. In the disclosure, a die forming-chamfering treatment is set between a laminating-embossing treatment and a coating with an ultraviolet curable paint, and thereby a chamfer embossing could be formed on the surface of the workpiece through pressing.

A method for forming an uncured rubber component, the method includes conveying an uncured extruded rubber strip extruded continuously from an extruder using a conveyor, the conveyor including a first conveyor and a second conveyor located at a downstream side of the first conveyor in a convey direction, the step of conveying including shrinking the uncured extruded rubber strip, wherein the step of shrinking is such that the uncured extruded rubber strip, in a relaxed state of a U-shaped manner, passes through fluid held in a tank between the first conveyor and the second conveyor without being restrained so that the uncured extruded rubber strip shrinks freely while receiving buoyancy from the fluid, and cutting the uncured extruded rubber strip in a predetermined length to form an uncured rubber component, after the step of shrinking.
