This specification describes technologies relating to dispensing liquid materials. In general, one innovative aspect of the subject matter described in this specification can be embodied in apparatuses that include a container (203) coupled to an integrated pump cap (202), the integrated pump cap (202) including a pump coupled to an intake port to the container (203) and an output port configured to dispense liquids from the container (203) when the pump is activated.

A sustainable thermoplastic composition made by forming a mixture of virgin polypropylene and post-industrial-recycled material (PIR). The PIR may include a thermoplastic, elastomeric-polymer and a spunbond component. The mixture is melt-blended in an extruder. Extruded materials made from the mixture demonstrate little variance in the results of the IZOD Impact Test of materials containing 30 to 70 percent PIR, and a material containing 100 percent virgin polypropylene. In addition, the extruded materials containing 30 to 70 percent PIR demonstrate a substantially constant strain at yield, that strain at yield being substantially equal to that demonstrated by a material containing 100 percent virgin polypropylene.

A movable mold includes a main mold part, a separate mold part separate from the main mold part, and a relative movement mechanism moving the separate mold part relative to the main mold part in a driving direction of a mold driver.

[Problem] The present invention relates to a manufacturing method for obtaining a molded article having an expanded layer in the molded article, wherein an expanding agent and device used to manufacture a resin having expansion properties, and a means for increasing expansion ratio are provided. [Solution] In the present invention, an expanding agent placed in a heating cylinder of a molding machine is configured as a liquid, the volume of the expanding agent is controlled, and the expanding agent is injected into a molten resin in the heating cylinder of the molding machine. The volume of the injected expanding agent can thereby be accurately measured each time. When a low-boiling liquid such as water, an alcohol, or an ether is used as the injected expanding agent, all of the liquid is vaporized by the temperature of the heating cylinder of the molding machine, and no residue thereof is therefore left in the molded article. When sodium bicarbonate water is used as the injected expanding agent, solvent water vaporizes and water vapor also becomes expandable gas, which is less expensive than using sodium bicarbonate as the expanding agent for a master batch using the resin that is to be molded.

Injection molded articles and methods for making them from bio-based materials are described. More specifically, injection molded articles and methods for making them from bio-based materials that behave like high-molecular-weight thermosets such as lignin or protein-based materials including corn gluten meal, corn gluten feed, distillers dried grains with solubles, wet distillers grains, modified wet distillers grains, canola meal, wheat gluten, barley, cottonseed meal, sunflower meal, linseed meal, soy, rapeseed, sorghum proteins, maize, rice proteins, potato proteins, cassava proteins, sweet potato proteins, yam proteins, plantain proteins, keratin, or collagen are described.

A method and a device for producing fibre-reinforced plastic mouldings, using coated fibre strands. For the coating of the fibre strands, an air flow of ionised air is produced and guided through a Venturi nozzle. Powder from a storage container is taken by means of a screw conveyor and supplied to the Venturi nozzle, a flow of a powder-air mixture being present or forming behind the Venturi nozzle in the direction of flow. This stream is introduced into a chamber and fibre strands that are earthed or ionised unlike the powder are passed through the chamber and through the powder-air mixture flowing through the chamber, powder particles being deposited on the fibre strands. The fibre strands guided out of the chamber therefore have a coating, and the fibre strands coated in this way are supplied to a plasticising device of an injection moulding machine or an extrusion machine.

An additive feeder system is presented which is operable for use in a plastic injection molding machine including an injection component and a clamping component. The additive feeder system includes a feeder control unit, a feeder supply mechanism and feeder dosage control mechanism. The additive feeder system is operable to provide a specific dosage of the additive materiel in real-time for mixing with the raw material to achieve desired product characteristics. The additive feeder system may be applied to injection molding and extrusion, such as molding processes, plastic molding processes, blow molding, compression molding, extrusion molding, injection molding and laminating, and comprising additive feeders, for example for color mixing and nutrient supplements.

A masterbatch (C) containing thermally expandable microcapsules (A) and a carrier resin composition (B) is provided. The carrier resin composition (B) contains a carrier resin (B1) and a plasticizer (B2), the carrier resin (B1) being an acrylic resin having a weight average molecular weight of 8,000 or more and 350,000 or less, and the plasticizer (B2) being an acrylic plasticizer having a weight average molecular weight of 1,000 or more and 20,000 or less. The carrier resin composition (B) is substantially compatible with a polycarbonate resin and has a shear viscosity of 1.0 Pa.Math.s or more and 1.510.sup.6 Pa.Math.s or less at 80 C. The occurrence of whitening is suppressed and a good appearance can be obtained in an injection molded foam made with the masterbatch. A polycarbonate resin composition, an injection molded foam, and a method for producing an injection molded foam are provided.

A method for using an injection mold for manufacturing plastic components, in particular components of power tools, the injection mold containing a sprue plate, a push-in device and an ejector plate. A cavity is between the sprue plate and the ejector plate when the sprue plate and the ejector plate are in an assembled state, and the ejector plate containing a fiber channel, through which a fiber bundle having a thermoplastic matrix is transportable to the cavity, via the push-in device, along at least part of the sprue plate. The method includes assembling the sprue plate and the ejector plate; heating the fiber bundle together with the thermoplastic matrix; positioning the fiber bundle at the cavity via the push-in device; introducing a liquid plastic into the cavity through a channel of the sprue plate; and introducing the fiber bundle into the cavity so that the fiber bundle is positioned in the cavity by the stream of liquid plastic.

A method of forming a thin-walled skin includes coating at least one side of a mold cavity of a molding tool, evacuating air from the mold cavity, and filling the mold cavity with a molten polymeric resin. Among other optional variations of the disclosed method, an inert gas is injected into the molten polymeric resin simultaneously with the step of filling the mold cavity with a molten polymeric resin. As a result, high quality, large, thin-walled skins are produced by the teachings of the present disclosure.
