A conveyer module, small fragments of which are detectable by X-ray and magnetic sensors, is formed from a compounded mixture of a thermoplastic polymer and a ferrous metal powder. The thermoplastic polymer comprises a polyketone constituting less than 85% by weight of the mixture. The ferrous metal powder is a 400 series stainless steel constituting between 16% and 20% by weight of the mixture.

The present invention relates to a composite component including a metal component having a substantially cylindrical shape or a substantially annular shape, and a ring-shaped bonded magnet disposed on the outer periphery of the metal component, the ring-shaped bonded magnet containing a thermoplastic resin, magnetic particles, and rubber particles.

A method and an apparatus for producing a radially aligned magnetorheological elastomer molded body containing a matrix resin and a magnetic filler are provided. The method includes the following: placing a permanent magnet 11 in at least one position selected from positions that are spaced from a metal mold 14a having a cavity 14b and located above and below the center of the metal mold 14a; providing a closed magnetic circuit that allows a magnetic flux 19a generated by the permanent magnet 11 to pass through the metal mold 14a from a side thereof, filling the cavity 14b with a composition containing the matrix resin and the magnetic filler; and molding the composition while the magnetic filler is radially aligned. With this configuration, the elastomer material is molded while the magnetic filler is radially aligned by using the permanent magnet.

The application relates to a plastic moulding for a moulding arrangement including a housing for another plastic moulding of the moulding arrangement, wherein the housing is formed within a moulding body of the plastic moulding including a weldable material in at least some areas. It is contemplated therein that a contact element is arranged on the moulding body, the contact element at least partly including an electrically conductive material and limiting a recess of the moulding body adjoining the housing in at least some areas. The application further relates to a moulding arrangement and a method for producing a moulding arrangement.

A coil component includes a magnetic portion that includes metal particles and a resin material, a coil conductor embedded in the magnetic portion and having a core portion, and outer electrodes electrically connected to the coil conductor. The magnetic portion includes an outer coating and a magnetic base having a protrusion portion. The protrusion portion is inserted into the core portion. The filling factor of the metal particles in the magnetic base is higher than the filling factor of the metal particles in the outer coating.

A method for the production of a glassy metal polymer composite is disclosed. The method comprises adding a polymer and a metal to an extruder, wherein the extruder is heated to an extrusion temperature greater than the melting point of the polymer and the melting point of the metal; mixing the metal and the polymer in the extruder for a predefined residence time; and co-extruding the composite from the extruder.

A slurry composition for forming an article using additive manufacturing is provided. The slurry composition comprises a carrier having a viscosity of at least 0.001 cP at normal temperature and pressure. The carrier is adapted to be flowable through a nozzle. The slurry composition further comprises a material selected from the group of a metal-containing material, a ceramic-containing material, an inorganic carbon-containing material, a silica-containing material, and combinations thereof.

Expanded graphite and/or vermiculite are introduced into the friction lining mixture to eliminate or substantially reduce the amount of binder present therein. The friction lining at most contains from 2.5% by weight of binder. By omitting/reducing binder, the production is very stable and the friction linings can be easily reproduced. The process steps of hardening (including the hardening furnace) and scorching (including the necessary equipment) can be omitted when making such friction linings.

A method for producing magnet-polymer pellets useful as a feedstock in an additive manufacturing process, comprising: (i) blending thermoplastic polymer and hard magnetic particles; (ii) feeding the blended magnet-polymer mixture into a pre-feed hopper that feeds directly into an inlet of a temperature-controlled barrel extruder; (iii) feeding the blended magnet-polymer mixture into the barrel extruder at a fixed feed rate of 5-20 kg/hour, wherein the temperature at the outlet is at least to no more than 10 C. above a glass transition temperature of the blended magnet-polymer mixture; (iv) feeding the blended magnet-polymer mixture directly into an extruding die; (v) passing the blended magnet-polymer mixture through the extruding die at a fixed speed; and (vi) cutting the magnet-polymer mixture at regular intervals as the mixture exits the extruding die at the fixed speed. The use of the pellets as feed material in an additive manufacturing process is also described.

Apparatus and methods for improved composition of floor coverings, utilizing bio-renewable materials, is disclosed. Floor coverings, or tacky mats, may be used in cleanroom environments to capture particulate matter from foot and equipment traffic. Bio-renewable materials may include thermoplastic starch (TPS) blends made from sustainable raw materials such as corn, tapioca, or the like. These bio-renewable materials may be blended and coextruded with synthetic or petro-based polymers. This reduces the environmental impact on production and disposal of the floor mat, while maintaining the physical and mechanical properties demonstrated by pure synthetic polymers.
