摘要： A method for producing a part consisting of a polymer material involves injection-moulding said polymer material in a mould comprising a main section for forming the part and an additional section for forming an add-on for the part. The additional section is arranged between the injection point and the main section. The part and the add-on are separated by cutting.

摘要： The purpose of the present invention is to make it possible to shorten the time required for a burr removal step and make it difficult for the burrs to detach from a sheet member in a step for removing the burrs together with the sheet member. For removal, by making the burrs to adhere to a pliable sheet member such as paper or nonwoven fabric that has been incorporated beforehand in the molding die and stripping the sheet member from the molding die, the burrs are removed together with the sheet member. The present invention is characterized in that in order to make it difficult for the burrs to detach from the sheet member during the stripping, a radiused shape with an arc-shaped cross-section is formed by the molding die on the areas surrounding the sections where the burrs adhere to the sheet member.

摘要： Technique to provide a molding die which can easily release a minute optical element in a state of favorable surface accuracy, while bending or rupture of a gate portion attached to the optical element is prevented. By making a first outer circumferential transfer surface 21A of a fixed die 20 and a first gate-forming surface 31A flush with each other, a notch shape is not formed on a portion M1 connecting an outer circumferential portion FL on the fixed die 20 side and a gate portion GP. Furthermore, by pushing out the runner portion RP at the same angle as a taper angle α of a side-surface transfer surface 23A on a second gate-forming surface 32A side, bending deformation or the like of the gate portion GP which can occur when being pushed out to a direction perpendicular to a mold mating surface PL1 can be prevented.

摘要： The present invention relates to a mobile phone protection case film with a transparent part and a method for manufacturing the same, and specifically a method for manufacturing a protection case film inserted in a protection case cover hinged to one side of a protection case for receiving the back and the sides of a mobile phone so as to open or close the front of the mobile phone, includes the steps of: assembling a first die and a second die so as to form a cavity conforming with the shape of the protection case film; filling the cavity with a molten resin through a gate provided in one side of the cavity; compressing the molten resin filling the cavity by closely contacting the first die and the second die with each other; cooling or hardening the molten resin; removing the .molded product by separating the first die and the second die; and cutting off the gate from the molded product. Thus, the method can considerably reduce the processing time and cost compared to the conventional processing method using a numerically controlled processing machine, and minimize the flaw rate by eliminating the errors according to the skill of a worker so as to improve the reliability of the product.

摘要： Embodiments of a method of injection molding with two molding steps and tools for this method are described. The transfer tool for high-volume manufacturing allows transfer of molded parts from one injection molding tool to another injection molding tool without separating the molded part from runners and without degating. The single step transfer, which can be performed without degating and without separating the molded parts from one another, can reduce cycle time as well as complexity.

摘要： A molding arrangement serves for molding articles at each stroke of an injection-molding machine in which an injection mold is mounted. The articles are composed of components made of different materials in cavities formed in the injection mold, with each cavities corresponding to the shape of a component whereby identical cavities are separated by angular distances and placed at equal distances from a central axis of the injection mold and parts of the cavities are formed in a separately movable section of the movable mold half. The injection molding arrangement includes an operation part for displacing the section to-and-fro between closed and open positions of the injection mold and in open positions to turn the section about the central axis angles corresponding to the angles between the cavities to form whole cavities in the injection mold in closed position.
