The apparatus may also include a mold; and a drain connecting the mold and the overflow container or being part of an overflow container outlet for drawing off resin of the overflow container.

A method of forming a nonwoven article comprising receiving fibrous material comprising thermoplastic fibers; processing the fibrous material to produce short fibers, wherein the processing step comprises granulation using at least one granulator with a screen; distributing the short fibers approximately evenly across an area to form a short fiber web, wherein the distributing step comprises a use of a recyclate spreader; heating the short fiber web to fuse the short fibers to form a nonwoven material; and forming a sheet of the nonwoven material.

A method of manufacturing a lavatory includes mixing recycled vitreous cull, particulate matter, and resin to form a composition; pouring the composition into a mold; and curing the composition in the mold to form the lavatory. Furthermore, another method of manufacturing a lavatory includes mixing vitreous cull, fiberglass resin composite cull, particulate matter, and resin; pouring the composition into a mold; and curing the composition in the mold to form the lavatory.

A method of manufacturing the foamed shoe material and semi-finished product including the following steps. Step S1: a foamable material is injected into a cavity of a blank mold to solidify, thereby generating a semi-finished product of the shoe material and a runner waste that are unfoamed. The runner waste could be shed for reusing directly as the foamable material without a granulating process. Step S2: the semi-finished product is cooled down and put into a cavity of the foaming mold, and the semi-finished product is evenly foamed in the cavity of the foaming mold to obtain a shoe material wherein the waste generated during the method of manufacturing the foamed shoe material could be effectively reused, and the yield rate of the shoe material thereby enhanced.

A foamed shoe materialincludes a foamed body divided into a plurality of sections, comprising a fore section, a heel section, and an arch section, and the arch section is located between the fore section and the heel section.

In a system and a method for reprocessing ultra-high molecular weight polymer film offcuts, the system comprises a feed device 202 and a comminution device 203. The feed device is configured to provide an ultra-high molecular weight polymer film offcut to the comminution device. The comminution device comprises at least one cutting screen, wherein the cutting screen comprises a plurality of screen openings and a plurality of cutting projections, wherein at least one cutting projection spans a cutting opening allocated to it, and wherein the comminution device is configured to generate relative motion between the cutting screen and the fed polymer film offcut in order to comminute the polymer film offcut.

A method of making a flexible package made of polymeric film is provided. The method comprises the steps of: a) obtaining post-industrial recycled material from post-industrial recycling of precursor polymeric film formed of precursor polymeric material which is substantially the same as the virgin polymeric material of step c), b) providing at least 30 weight-% post-industrial recycled material obtained in step a) based on the overall weight of the polymeric film, c) providing up to 70 weight-% of virgin polymeric material based on the total weight of the polymeric film, and d) jointly melting the virgin polymeric material and the post-industrial recycled material. The method comprises the steps of: e) extruding the molten polymeric material and molten post-industrial recycled material to form a polymeric film, f) providing print on one or both surfaces of the polymeric film, and g) converting the polymeric film into the flexible package.

A method for producing a resin composition according to the present invention comprises: a management step for performing management by recovering non-standard products generated in a manufacturing process of a thermoplastic resin and classifying the products according to grades based on a design factor A; a regeneration step for obtaining regenerated products by collectively regenerating the non-standard products classified under each grade; and a compound step for screening the regenerated products obtained in the regeneration step, on the basis of a design factor B for compounded products, and carrying out compounding on the resulting products.

A liquid storage container containing: a storage portion configured to store a liquid; a discharge portion configured to discharge the liquid; and a sealing portion configured to seal the discharge portion, wherein the liquid storage container contains a compound whose absorption spectrum peak changes when a pressure is applied to cause deformation, and the compound exhibits tribochromism.

A drying device includes a mixing unit fixedly connected with a drying unit. The drying unit is erected on a bench. The mixing unit includes a virgin material loader and a regrind material loader, which are respectively connected to the top of a mixing component. The bottom of the mixing component is connected with a drying unit through a buffer hopper with level sensor. A drying process with the functions of mixing and drying plastic particles integrates the mixing process and the drying process into a set of processes, saving the control cost and working space. The regrind materials are directly fed by the suction device above the equipment, which can be used as soon as they are produced, reducing the cost of manual treatment and reducing the absorption of air moisture. The user can control the mixing proportion and drying parameters on the control panel at the same time.
