Case Study 1

The Background

Indo-MIM was approached by a manufacturer, who needed a magnetic & highly corrosion resistant material (MIM Fe3%Si) Solenoid base with 10mm x 28mm x 31mm dimensions and needed to weigh at 17 grams. For this manufacturer, Indo-MIM delivered the perfect solution.

The Problem

There was non-availability of requisite material in wrought form. The material needed to be highly magnetic and corrosion resistant, & hence the part had to go through various processes. Firstly, it had to be stamped after which magnetic pins were welded to non-magnetic circular sheet metal, which then had to go into electro less nickel plating. All these processes increased the manufacturing costs and decreased the quality of the component. The perpendicularity of the pins was difficult to maintain since the pins were being welded on to the sheet metal.

The Solution

Indo-MIM was the best place for the above-mentioned manufacturer. The requirement was close tolerances, which was an area of excellence for Indo-MIM. Thus, Indo-MIM developed a custom-made magnetic material for the product as per the manufacturers’ specifications. Its Core & Cavity in the tool accommodated the nine pins, which did away with the welding and stamping operations strengthening the final product.
Indo-MIM also created a Multi Cavity Tool, which helped to meet their high volume requirements.

Case Study 2

The Background

Indo-MIM has proved its prowess in manufacturing sector too. For one of its prestigious clients who are into manufacturing of locks, Indo-MIM provided cutting-edge solution. The lock manufacturer required case hardened steel (MIM 8620) for a lock with dimensions 23mm x 23mm x 13.5mm weighing 14.5 grams and Indo-MIM delivered the perfect solution.

The Problem

The manufacturer had difficulties with multistage machining operations. Besides, the manufacturer faced difficulty to machine 3D complexity features like – Slots, grooves & holes for which the manufacturer had tried investing in casting, but couldn’t meet the surface finish requirements. Therefore, the manufacturer had to undergo machining to meet its critical tolerances. Burrs created during machining affected the functionality of the part and both machining & investment casting could not meet the growing requirements of the customer.

The Solution

Indo-MIM has now become an innovative technology resource for parts having 3D complexity. It has devised simple but very effective solutions for its esteem customers. Indo-MIM’s case hardened MIM material was easily able to meet the material demands and the mechanical properties needed by its customer for their products. Indo-MIM specially designed a MIM tool with 2 inserts and 4 slides. Further, Indo-MIM also avoided all post-MIM secondary operations for features like grooves, slots and holes without any burrs. It resulted in a satisfied customer, who witnessed 30% savings on the overall cost of the project.

Case Study 3

The Background

Indo-MIM’s commitment to deliver the best solution and continuously innovate is once again shown here. A manufacturer was facing a challenge with its state-of-the-art vision application. The manufacturer needed a Stainless steel (MIM 17-4PH) part for its endoscopic applications, which weighed 29.34 grams with dimensions of 115mm x 15mm x 22 mm.

The Problem

The manufacturer had faced difficulties to machine critical features like – Slots, holes, surfaces & protrusions. The manufacturer saw that investment casting couldn’t build the tool to accommodate all the critical features. The manufacturer also needed a good surface finish with the Ra value of 1.2 microns and threads at an angle through MIM inserts. Besides, the manufacturer also faced distortion during machining and heat treatment operations.

The Solution

Indo-MIM manufactured the required part with MIM 17-4 PH, which is a highly corrosion resistant material. Also Electro polishing was further done on the part to improve the surface appearance and the corrosion resistance. The ingenious solution given by Indo-MIM resulted in reduction of the overall weight of the platform and MIM tool accommodated all the critical features, including threads produced through the MIM tool using thread inserts.
