APPARATUS AND METHOD FOR MAKING OBJECTS FROM RECYCLED POLYMERIC MATERIAL
An apparatus comprises a nozzle for supplying a flow of polymeric material, a separating element for separating a dose of polymeric material from the flow supplied by the nozzle, at least one mould for making an object by compression moulding the dose, at least one conveying element for conveying the dose separated by the separating element towards the mould. The conveying element is movable along a path in an atmospheric environment. The apparatus further comprises a recycling device intended for receiving a polymeric material to be recycled and for providing at its outfeed a melted regenerated polymeric material suitable for being moulded. The nozzle is connected to the recycling device so that the nozzle is fed with the regenerated polymeric material coming from the recycling device.
Thermoplastic pavement marking composition
A pelletized road marking composition includes a binder mixture, a filler mixture and bentonite clay. The binder mixture includes at least one alkyd ester, at least one wax, at least one ethylene copolymer, and at least one plasticizer. The filler mixture includes at least one coloring additive, reflective elements, and at least one inert inorganic filler. The components of the road marking composition are mixed and melted and processed into pellets. The bentonite clay added to the composition prevents the pellets from clumping when stored at elevated temperatures.
SYSTEMS AND METHODS FOR DIRECT HEATER DIAGNOSTICS FOR A HOT MELT LIQUID DISPENSING SYSTEM
Systems and methods for direct heater diagnostics for a hot melt liquid dispensing system are disclosed. At least one of a current measurement or a voltage measurement is received from a respective current and/or voltage sensor positioned at an electrical circuit that supplies electric power to a heater associated with the dispensing system. The heater can be for an applicator or heated hose attached to the dispensing system, a melter of the dispensing system, or a pump of the dispensing system. A state of the electrical circuit is determined based on the at least one of the current or voltage measurement.
MELTER WITH SELF-CLEANING FILTER
In one example, a melter has a housing, a heater, a vent, and a filter medium. The housing defines a receiving space that supports adhesive therein. The heater heats the receiving space of the housing to melt the adhesive. The melter defines an adhesive inlet therein that receives adhesive carried by a transport supply gas into the receiving space. The vent extends through a wall of the melter and permits the transport supply gas to escape from the melter. The filter medium is supported in the vent to capture particulates from the transport supply gas escaping the receiving space, and is positioned relative to the receiving space such that heat from the receiving space causes the particulates captured by the filter medium to melt and fall into the receiving space.
MODULAR ADHESIVE DISPENSING DEVICE
An adhesive dispensing device (10) includes a melt module (12) including a housing (78) that defines a receiving space to receive adhesive and a heater (114) to heat the housing to melt the adhesive, and a control module (14) releasably connected to the melt module. The control module includes a controller (36) to automatically recognize a characteristic associated with the melt module and operate the melt module using instructions stored on the controller that correspond to the characteristic of the melt module. A method of operating the adhesive dispensing device is also disclosed.
Method for producing a planar composite component and composite component produced thereby
A method for producing a planar composite component having a core layer (B), which is arranged between and integrally bonded to two cover layers (A, A′), wherein the cover layers contain a cover-layer thermoplastic and wherein the core layer contains a core-layer thermoplastic, comprises the following steps: a) a heated stack with layer sequence A-B-A′ is provided; b) the heated stack (A-B-A′) is pressed; c) the pressed stack is cooled, whereby the planar composite component with consolidated layers integrally bonded to each other is formed. To improve the production method including the producibility of planar 3D components, it is proposed, that at least one of the cover layers (A, A′) in unconsolidated form comprises a fibrous nonwoven layer of 10 to 100 wt.-% thermoplastic fibers of the cover-layer thermo-plastic and 0 to 90 wt.-% of reinforcing fibers having an areal weight of 300 to 3,000 g/m.sup.2; the core layer (B) in unconsolidated form comprises at least one randomly-oriented-fiber nonwoven layer (D) formed from reinforcing fibers and thermoplastic fibers of the core-layer thermoplastic,
and that after the pressing the consolidated core layer(s) has/have an air pore content of <5 vol.-% and the consolidated core layer has an air pore content of 20 to 80 vol-%.
Compositions and Methods for the Recycling of a Mixed Plastic Feedstock
Compositions and processes for the tertiary recycling of mixed plastic waste into a stable and homogeneous plastic feedstock material are provided. The processes and compositions allow for the tertiary recycling of unsorted, unwashed and unidentified mixed plastic waste, including waste mixtures comprising polymer macromolecules with different molecular weights and polymer chain lengths. The processes include the blending of a mixed plastic waste feedstock with a recycling composition and virgin carrier materials comprising at least one alluvium material.
Thermoplastic extrusion melting kettle
A melting kettle for processing of thermoplastic material. The kettle disclosed herein obtains heat transfer by use of an oil jacketed tank with an adjoining main tank for storage of hot oil and a hose tank for recovery of the hot oil. Oil expelled from the oil jacket is directed to the main tank through an opening. Spillage of oil from the hose tank is directed to the main tank through an aperture. The melting kettle reduces the space needed for oil storage, and increases operator safety by eliminating additional transfer lines. Dual kettles benefit by having the adjoining main tank placed therebetween.
DEVICE AND METHOD FOR FEEDING MOLTEN PLASTIC MATERIAL INTO A MOLDING CAVITY
The device for feeding molten plastic material into a molding cavity (30) includes a melting chamber (20) in which metered solid plastic material is introduced, a sonotrode (10) provided for tightly inserting a portion thereof into said melting chamber (20), causing the plastic material to melt by means of vibration, and relative movement of the sonotrode (10) and melting chamber (20) allows driving the molten plastic material inside a molding cavity (30) communicated with said melting chamber (20), the device including resistance sensors (40) allowing an electronic control device (50) to know the resistance that the plastic material has against the movement of the sonotrode (10).
Method for manufacturing main body of faucet
A method for manufacturing a main body of a faucet comprises separately molding a base body in which a valve V is installed, a first part in which a hot water passage and connecting portion are formed, a second part in which the cold water inlet and a connecting portion are formed, and a third part in which a water discharge port and connecting portion are formed, the base body and three parts being formed of a composition of ABS resin and glass fibers and combining the base body with the connecting portions of the three parts; integrating the base body and three parts into a main body of a faucet by overlaying the surfaces of the combined main body with ABS resin molten at temperate of 190° C. to 210° C. by injection molding process; and plating nickel-chromium on the exterior of the main body for protection of external molding portion.
