In an additive 3D printing method for production of shaped articles from silicone elastomers, an elastomeric shaped body is built up step by step, by repeatedly precisely positioning portions of the crosslinkable silicone material and crosslinking by means of electromagnetic radiation. Charges that occur on the surface of the print material or on the article are neutralized by means of an ionization system.

The invention relates to a cold runner block in a vertically operating injection molding machine for processing elastomer materials with an upper fixed molding platen and a molding platen arranged thereunder which is movable relative to the fixed molding platen, between which a molding tool having a plurality of mold cavities is arranged and wherein the cold runner block is arranged between the fixed molding platen and the molding tool, the cold runner block containing a distribution plate having the cold runners and containing a nozzle plate with nozzles each assigned to one of the plurality of mold cavities, which is characterized in that the distribution plate formed from a plurality of distribution strips (10-40) is arranged on a retaining plate (2), which can be fastened to the fixed, feed-side molding platen in such a way that each distribution strip (10-40) is connected by means of two bolts (3) to the retaining plate (2) in that the head (5) of each bolt (3) facing away from the distribution strip (10-40) forms a retaining element which is T-shaped in section, the retaining element being displaceably guided in the direction transverse to the distribution strip's longitudinal axis in guide rails (50) which are formed in the retaining plate (2) and are designed in section to complement the bolt head (5).

Non-time dependent measured variables are used to effectively determine an optimal hold profile for an expanding crosslinking polymer part in a mold cavity. A system and/or approach may first inject molten expanding crosslinking polymer into a mold cavity, then measure at least one non-time dependent variable during an injection molding cycle. Next, the system and/or method commences a hold profile for the part, and upon completing the hold profile, the part is ejected from the mold cavity, whereupon a cure profile is commenced.

A hydraulic mount is provided and includes: an inner core, a cage that surrounds the inner core, an elastomer body that extends between the inner core and the cage and elastically connects them to each other, and an outer sleeve that encloses the cage. The elastomer body has a first circumferential fluid chamber recess and a second circumferential fluid chamber recess. The first fluid chamber recess and the second fluid chamber recess are each limited in a radially outwards direction by the outer sleeve to form a first fluid chamber and a second fluid chamber. The elastomer body is configured to be substantially undercut-free in an axial direction on its axial end faces. The elastomer body and the cage are configured to be substantially undercut-free in the region of the first fluid chamber recess and the second fluid chamber recess, at least in two predetermined, mutually opposite radial directions.

A process unit and methods are disclosed. One process unit including a pultrusion unit having a pultrusion channel, with the pultrusion channel being limited by at least one shaping wall. The process unit further includes an extrusion unit having an extrusion channel and an opening for removing the extrudate out of the extrusion channel, a cutting unit having a moving cutting element for cutting off the extrudate with the moving cutting element, and a conveying device for conveying a raw extrudate from the pultrusion unit into the extrusion unit. The cutting unit comprises a component that can be caused to move in a rotational manner and the component is mechanically coupled to the cutting element by a mechanical coupling device, such that the rotational movement of the component determines the movement of the cutting element.

A rubber distributor for injection molds wherein the distributor comprises two or more modular units, sleeves each interchangeably insertable in a modular unit, one or more injectors to feed melted rubber to the distributor and one or more discharge nozzles to discharge the melted rubber from the distributor towards an external mold. Each sleeve has a through hole extending along the longitudinal axis of the same sleeve. Sleeves have a groove extending over respective side surfaces. Groove and the inner surface of the respective housing in the modular unit define a coil that can be supplied with a thermoregulating fluid whenever the sleeve is inserted into a modular unit. The modular units can be constrained to one another to define one or more channels for distribution of melted rubber that extend from an injector to one or more discharge nozzles, depending on a desired path. Modularity of the units allows the distributor to have ducts for distribution of melted rubber of a desired geometry. Through holes of the sleeves define corresponding lengths of at least one channel for distribution of melted rubber. Since the sleeves are cooled and the melted rubber flows inside them, the distributor is thermoregulated.

A modular highway warning strip system which comprises a modular warning strip segment having first and second ends, a length extending between the first and second ends, two opposing lengthwise sides, a width extending between the opposing lengthwise sides of the segment, top and bottom surfaces, and a thickness. Each of the first and second ends comprise at least one male protrusion and at least one female receptacle, wherein the at least one male protrusion is configured to engage the at least one female receptacle for joining a plurality of the segments together end-to-end. A segmented metallic plate is disposed between upper and lower rubber layers, the segmented plate comprising a plurality of segments separated by slits comprising living hinges.

An electrically-driven rotor iron core magnetic steel chamber dispensing device is introduced. Dispensing units each include a dispensing channel, dispensing head, plunger barrel, plunger and stop-injection opening pin. The dispensing channel is above the dispensing head and in communication with the dispensing head. The dispensing head is disposed at the top of the plunger barrel and in communication with the plunger barrel. The plunger is displaced in the plunger barrel to move up and down relative to the plunger barrel. The stop-injection opening pin includes a pin body disposed vertically, arranged beside the plunger barrel, and fixed to a lower mold from inside. A pin head portion is disposed at the top of the pin body. A barb is disposed between the pin head portion and the pin body. The pin head portion protrudes into the dispensing channel, allowing molten plastic in the dispensing channel to enter the barb.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.

A connection including a first profile having a first end and a first lumen, the first profile including a first polymeric material and a second profile having a second end and a second lumen, the second profile including a second polymeric material, a metal, or combination thereof, wherein the first end and the second end are coincidently welded via an ionized gas treatment.
