摘要:
A method of molding a solid article such as a syringe with zero draft or low draft is disclosed. The method includes heating a low draft mold to expand it, then injection molding the part, followed by cooling at least part of the low draft mold element to thermally contract at least a portion of the low draft element away from the solid low draft formed surface sufficiently to release the low draft element from the low draft formed surface. Syringes and other articles formed by this method are also disclosed having and interior draft angle of 0 to 0.5 degrees, optionally at least substantially zero degrees. The syringe plunger can be selectively coated with lubricity coatings and other functional coatings to improve performance of the syringe.

An arm rest assembly that includes a thermoplastic arm rest body that defines an internal cavity and a support structure disposed within the internal cavity. The support structure is chemically compatible with the thermoplastic arm rest body such that a homogeneous chemical bond is formed between the support structure and the thermoplastic arm rest body. An arm rest cover is coupled to the arm rest body such that the internal cavity is enclosed by the arm rest body and the arm rest cover

The present invention relates to a resin composition containing: 5 to 82 parts by weight of an aromatic polyester (component A); 0 to 50 parts by weight of an aromatic polycarbonate (component B) having a deflection temperature under load (A method) of 110°C or higher and 140°C or lower: 10 to 90 parts by weight of a highly heat-resistant aromatic polycarbonate (component C) having a deflection temperature under load (A method) of 145°C or higher; 0 to 10 parts by weight of a graft-copolymer (component D) containing 40 to 90% by weight of a rubbery polymer; 0 to 10 parts by weight of an ethylene copolymer (component E); 2.5 to 50 parts by weight of a silicate filler (component F); 0 to 10 parts by weight of an electric conductive filler (component G); and 0 to 2 parts by weight of a phosphorus compound (component H), provided that the total amount of the all components are 100 parts by weight, wherein the total amount of the component D and the component E is from 0.5 to 10 parts by weight, and the resin composition has a deflection temperature under load (A method) of 130°C or higher. When the resin composition is used, a resin molded article suitable for an automobile exterior or outer panel member can be provided, which maintains a coating appearance consistency with a metal site, has a heat resistance capable of coping with an high temperature exposure during the baking of the coating material, has a good surface property, has an inhibited deformation caused by a linear thermal expansion or humidity change, is light, has excellent rigidity, impact property, chemical resistance, and coating layer adhesion, and has a good flowability during processing.
摘要:
It is presented a method for producing a cured polymer structure from a polymer compound which is UV curable and partly UV transparent. The method comprises injecting the polymer compound into a mold (2), which mold (2) has at least one wall (7) defining a mold space (6) for receiving the polymer compound in the mold space (6). The at least one wall (7) of the mold (2) is UV transparent and comprises a thermoplastic polymer. The polymer compound is then irradiated through the at least one wall (7), by means of at least one UV semiconductor light source, thereby curing the polymer compound to form the cured polymer structure. An assembly for producing a polymer structure and a mold (2) is also presented herein.

A waterproof type control unit is provided in which a case member has: a base plate on which a case member bottom surface is formed; and a peripheral wall which is fixed to the base plate. The peripheral wall includes a first peripheral wall edge portion and a second peripheral wall edge portion, which are disposed on the case member bottom surface so as to be distant from each other, the peripheral wall surrounding a controller from the first peripheral wall edge portion to the second peripheral wall edge portion. The connector member includes a connector member main unit which is disposed in a space between the first and second peripheral wall edge portions. A peripheral wall groove, which is open toward the connector member main unit, is disposed in each of the first and second peripheral wall edge portions. A bottom surface of the peripheral wall groove is inclined with respect to the case member bottom surface. A base plate groove, which connects each peripheral wall groove, is disposed on the bottom surface of the case member. A seal material is filled into the space formed between each of an inner surface of the peripheral wall groove and an inner surface of the base plate groove, and the connector member.
