The present invention relates to a method for the production of injection-moulded, reinforced moulded parts, the fibre orientation of which is specifically adjusted on a local basis. Via suitable, dynamically controlled supplementary heating in the wall of the injection mould which is used (variotherm heatable channel), a local cavity region is hereby heated at the time of injection to a temperature in the region of or above the solidification temperature (in any case above the crystallisation temperature in the case of partially crystalline plastic materials or above the glass transition temperature in the case of amorphous plastic materials) of the polymer (plastic material moulding compound).

Provided is an injection molding die capable of adjusting a size of a support member, preventing bending of a mold, and preventing occurrence of burrs without removing the mold and making the support member again. The present invention provides an injection molding die including a fixed mold and a movable mold that face each other, the fixed mold and the movable mold being clamped to form a cavity for molding a molded product, the injection molding die further including at least one support member that is provided to abut on a surface opposite to a surface on which the cavity is formed in either or both of the fixed mold and the movable mold, the at least one support member being a stretchable support member in a direction of the cavity.

Methods for preparing pre-dynamic cross-linked polymer compositions are described. Methods of preparing dynamic cross-linked polymer compositions using pre-dynamic cross-linked polymer compositions are also described.

The present disclosure provides a process for preparing a cured transparent rubber composition containing a synthetic isoprene polymer(s), a transparent polymer(s), a curing agent and additives. The process includes mixing the components at a temperature ranging from 50 to 130° C., curing the compound with peroxide and allowing the compound to mature. The maturated compound is fed to an injection molding machine. The cured transparent rubber composition prepared using the methods described herein has a haze of less than 30% and a total light transmission of more than 80%. The disclosure further provides an article including the cured transparent rubber composition, in particular for medical applications and artificial nipples.

An injection mold assembly for injection molding an object includes a first mold tool having a first tool surface and a second mold tool having a second tool surface. The first and the second tool surfaces are cooperatively configured to define a mold cavity between the tool surfaces for an injection molding of an object. The first mold tool has a tool element with a first side that has the first tool surface, and with a second side opposite the first side. Multiple fins extend from the second side of the tool element. A base supports the fins. The tool element, the fins and the base define a coolant flow cavity at the second side of the tool element. A method of designing the mold assembly is also disclosed.

An injection molded component includes a wall that has an inner wall surface and an outer wall surface. A sensor is molded into one of the inner wall surface and the outer wall surface. A channel is at least partially surrounding the sensor.

An extruder has a barrel extending from a feed inlet end to an extruder outlet end. The barrel has an inner surface, an outer surface, and a wall thickness between the inner and outer surfaces. The extruder also has at least one heating member positioned provided on the barrel; a screw drive motor drivingly connected to a rotatably mounted screw positioned within the barrel, whereby the screw is rotatable at various revolutions per minute (RPM); and a controller is operably connected to the screw drive motor to adjust the RPM of the screw based upon a temperature of material passing through and/or being extruded from the barrel. Methods for operating an extruder filling a mold are also provided.
