The invention discloses a manufacturing process of an inner magnetic rotor of a magnetic force pump. The steps are as follows: a. Manufacturing welding tooling for the inner magnetic rotor of a magnetic force pump; , and then spot-weld the sheath baffle, the sheath and the rotor seat to form the inner magnetic rotor blank of the magnetic pump; c, pick up the inner magnetic rotor blank of the magnetic pump and place it on the welding tooling of the inner magnetic rotor of the magnetic pump; d, Weld the cover baffle with the rotor seat, and weld the left and right ends of the cover with the rotor seat and the cover baffle respectively to make a semi-finished part of the inner magnetic rotor of the magnetic pump; e. Machine the semi-finished part of the inner magnetic rotor of the magnetic pump After processing and passing the inspection, the finished magnetic rotor in the magnetic pump is obtained. The manufacturing process of the magnetic rotor in the magnetic pump of the present invention adopts such a method that spatter does not occur during welding, which can ensure welding quality, eliminate product scrapping caused by internal stress, improve product qualification rate, and reduce manufacturing cost.

A process for removal of undesirable conductive material (e.g., catalyst material and seeped circuit material) on a circuitized substrate and the resultant circuitized substrates disclosed. Such process and resultant circuit effectively address the electrical shorting problems caused by nonremoval of the residual catalyst material and circuit material which has seeped under the residual catalyst material. The process includes the steps of: a) providing a catalyst layer (e.g., palladium and tin) having circuit pattern (e.g., copper) thereon; b) pretreating the catalyst layer and the circuit pattern (e.g., with a cyanide dip) for removal of undesirable portions of each which cause electrical leakage between circuit lines of the circuit pattern; c) oxidizing the catalyst layer and the circuit pattern (e.g., with chlorite, permanganate, hydrogen peroxide, or air at a temperature elevated above ambient conditions); and d) removing the undesirable portions of the catalyst layer and the undesirable portions of the circuit pattern (e.g., with a cyanide submersion). The resultant circuitized substrate includes a circuit pattern on a catalyst layer wherein undesirable portions of the catalyst layer and circuit pattern are completely removed between the circuit features of the circuit pattern so that electrical leakage between the circuit features does not occur.

An ignition apparatus includes a core, primary and secondary windings and a loop-shaped magnetic return path structure. The structure includes layers of wound strip steel or wound ferritic wire stacked in an outward fashion. The core is placed in an interior of the loop forming at least one air gap between a core end surfaces and the structure. A combined core and magnetic return path structure includes a continuous loop formed by winding ferritic wire either on a spool or on a mandrel and is then bonded. The bonded winding is cut to form two C-shaped portions. Each C-shaped portion has a central yoke that extends into a pair of parallel legs. The C-shaped portions are re-assembled over primary and second windings so that the legs form a pair of parallel branches. One branch acts as the core and the other branch acts as the magnetic return path.

The invention provides an in-mold injection mold for integrally molding a refrigerator decorative bar, which can solve the problems of high mold cost, high assembling cost, low efficiency and the like in the prior art. The in-mold injection mold for integrally molding the refrigerator decorative bar comprises a locating locking module, wherein the locating locking module comprises a front mold embedding block, a template A0, a line slide block, an oil cylinder and a locking block; the front mold embedding block and the line slide block are embedded on the template A0; a cavity is formed on one side wall of the front mold embedding block; a membrane cavity is formed on one side wall of the line slide block; the oil cylinder is fixedly arranged on the template A0; the expansion and retraction direction of the oil cylinder is vertical to the side wall of the membrane cavity; and one end of the locking block is in contact with one side wall of the line slide block. By using the arranged locating locking module, an in-mold injection membrane is laminated at the side surface of the product so that the refrigerator decorative bar is integrally molded in the in-mold injection mold; the production requirements can be satisfied by using one set of mold so that the mold manufacturing cost and injection molding production cost are reduced; and the assembling procedures of the decorative bar main body and the decorative bar are canceled so that the production efficiency is enhanced and the manpower cost is reduced.
