There are provided a core unit manufacturing apparatus and a core unit manufacturing method including: a molding device that fills a resin into a space portion in a core body; a resin transfer unit that transfers a resin material to the molding device to supply the resin material thereto; and a core transfer unit that carries the core body in and out of a part between a pair of dies of the molding device. The resin transfer unit and the core transfer unit are arranged such that: the resin transfer unit supplies the resin to the molding device from one side position of side surfaces of the molding device; and the core transfer unit carries the core body in and out of the molding device from the other side position of the side surfaces of the molding device, the other side position being different from one side position.

Embodiments of the present disclosure provide a method of forming a cover of a fuel intake system of a vehicle. The method may include providing a mold that defines a cover-forming cavity having a main body portion and a grounding strap portion connected to the main body portion, inputting a forming material into the cover-forming cavity to a specified level, allowing the forming material within the cover-forming cavity to cool and harden, separating the mold to expose the cover having an integrally molded and formed grounding strap, and removing the formed cover having the integrally molded and formed grounding strap from the separated mold.

A method and device for producing an optimized neck contour on preforms below the neck which is optimal for subsequent stretch blow molding. The geometry has a significantly thinner wall thickness than the neck itself. The preform can only be produced in the injection molding tool, when axial channels are used on the point or the vanes produce the thin points on the preform during injection molding. The thin-walled geometry on the preform can be produced outside of the mold during post-cooling by embossing. The preform is there removed in a cooled receiving sleeve and is cooled in the body by intensive contact cooling while no cooling contact is made with the preform neck due to the initial position of the embossing element. Due to the reheating of the neck they can be mechanically deformed into a new geometry advantageous for blow molding and thus wall thickness can be influenced.

An injection molding apparatus and method for adjusting the axial position of a valve pin in an injection molding system, the apparatus comprising: a top clamp plate, a heated manifold receiving and distributing an injection fluid to an exit of a fluid delivery channel to a cavity of the mold, an actuator comprising a housing having a chamber enclosing a drive member for driving a valve pin along an axial path of travel, the actuator housing slidably mounted and adapted for controlled upstream and downstream movement of the drive member along a path complementary to the axial path of travel of the valve pin, a mounting plate and an axial position adjustment screw screwably mounted within the mounting plate upstream of the housing of the actuator for controllably moving the valve pin to selectable starting or ending injection cycle axial positions.

Provided is a curable silicone composition and applications thereof. The curable silicone composition has low modulus and flexibility even at high temperature of a cured product formed therefrom, and superior stress relaxation properties, so that the cured product does not readily warp or become defective when integrally molded with a base material, and has superior demolding property (e.g. mold release) of the cured product after transfer molding. A curable silicone composition for transfer molding, where (1) the maximum torque measured from a molding temperature of room temperature through 200° C. using a moving die rheometer (MDR) is less than 50 dN-m, and (2) the loss tangent (tans) expressed by the ratio of stored torque value/lost torque value is less than 0.2.

A retaining pin for handling injection molded preforms includes a body including an internal body flow channel, and a plunger coupled to the body and movable relative to the body between advanced and retracted positions. The plunger includes an internal plunger flow channel. The plunger further includes a plunger abutment surface directed away from the body. The plunger is biased toward the advanced position and movable to the retracted position by engagement of the plunger abutment surface with an inner surface of a closed end of a preform when the preform and retaining pin are moved toward each other. The body flow channel and the plunger flow channel are in fluid communication when the plunger is in the retracted position. Fluid communication between the plunger flow channel and the body flow channel is inhibited when the plunger is in the advanced position.
