In a method for producing a housing of an electronic module, a lead with a bondable lead surface is injection molded with a plastic in a plastic injection mold such as to leave at least a part of each bondable lead surface from being injection molded and to form the lead with a pin recess which passes through the plastic and has a lead recess in the lead and which is sealed on opposing sides by a stamp component and a matrix component of the injection molded tool when the injection molded tool is closed, with the stamp component and the matrix component being injection-molded after the injection molded tool is closed. An electrically conductive pin element is inserted into the pin recess such as to guide the pin element through the lead recess of the pin recess.

A windowless multi-fiber ferrule including a ferrule body. The ferrule body includes a plurality of outer slots. The ferrule body defines an inner passage that extends through a length of the ferrule body from a front end to a rear end. The inner passage includes a main chamber and a row of parallel fiber bores. The ferrule body includes a first and a second major side which each define a plurality of slots. The ferrule body includes ferrule walls which are located between the main chamber and the major sides. The ferrule walls have a first thickness at the outer slots and a second thickness at the regions between the outer slots which is thicker than the first thickness. The main chamber includes sink locations adjacent the regions between the outer slots.

Provided are an electrical junction box for which the time required for production is short, and a method for manufacturing the electrical junction box. An electrical junction box houses an electric device. A plurality of external devices are connected to each other via the electric device housed in the electrical junction box. The electrical junction box includes a housing box and a connector. The housing box is provided with an insertion port 40 into which the connector is inserted, and an opposite opening that is opposite to the insertion port. The insertion port and the opposite opening have the same axial direction. Inside the housing box, a component can be attached to the connector.

Thermoplastic polyurethane (TPU) compositions, methods for producing TPU compositions, methods of using TPU compositions, and apparatuses produced therefrom are disclosed. Disclosed TPU compositions include a thermoplastic polyurethane polymer, a heat stabilizer, a flow agent, and a filler material. The filler may be a glass fiber. Disclosed TPU compositions have improved thermal stability and improved flow properties suitable for injection molding of articles of manufacture having a large plurality of fine openings or pores. Articles produced from the composition have superior thermal stability, abrasion resistance, and chemical resistance. Example articles include screening members for vibratory screening machines. Further embodiments include compositions without heat stabilizers, flow agents, and filler materials, and compositions in which two TPU materials having different harnesses are combined to generate a material with a pre-determined hardness. Injection molded screen elements having openings from 25 to 150 microns and open screening area from 10% to 35% are disclosed.

Methods and systems for creating cold plates are disclosed. For example, in one example method for manufacturing a cold plate made of a thermally-conductive plastic includes performing a first injection-molding process using the thermally-conductive plastic to produce a first unitary body, the first unitary body including one or more elongated sections forming a unitary body, performing a second injection-molding process using the thermally-conductive plastic to produce a second unitary body, the second unitary body incorporating the first unitary body so as to cover a majority of the first unitary body and form a respective coolant pipe body corresponding to each elongated section, and performing a machining process on the second unitary body so as to create a conduit in each respective coolant pipe body suitable for a fluid to pass through to create respective coolant pipes.

A production apparatus of a two-layer preform including an inner layer preform and an outer layer preform includes: an outer layer cavity mold for injection-molding the outer layer preform. A bottom surface of the outer layer cavity mold is provided with a protrusion for separating the inner layer preform disposed in the outer layer cavity mold from the bottom surface.

A drinking straw has an elongated body with a longitudinal flow channel. The user end of the body is closed and rounded for safety. A pair of lateral channels open onto the body adjacent the user end and provide fluid communication to the flow channel. The straw is injection molded, and a mold is provided which accommodates thermal expansion of a rod forming the flow channel. A pair of opposed cavity inserts form the lateral channels. To reduce bending stresses on the rod upon removal of the cavity inserts, one cavity insert is formed longer to the other. This longer cavity insert is removed prior to opening of the mold plates, and as such the straw and rod are supported against bending during this removal.
