Metal Injection Molding (MIM) Manufacturing Capabilities

Compounding

Harber Industrial Group is capable of maintaining high quality and maximum flexibility through the ability to manufacture our own MIM feedstock. Precise and error-proofed batch preparation of powders and binders are done in a well-controlled environment. Both batch and continuous compounding equipment is used to process the mixture into a consistent, high quality feedstock.

The mixing process and material characteristics are continuously monitored.

We use the latest and most precise closed-loop injection molding equipment on the market. Our machinery contains proprietary enhancements that we believe offer an extra level of performance and control. Automation is applied where appropriate to guarantee quality. We monitor the injection molding machine and its output continuously using SPC tools.

Injection Molding

Harber Industrial Group employs a proprietary solvent extraction process for removal of binder constituents before sintering. The process is environmentally sound and well monitored. Sintering takes place in either batch vacuum or high temperature continuous pusher furnaces. Our vacuum furnaces maintain precise temperature control using various process gasses that allows for the flexibility to process a wide variety of alloys. Our continuous sintering capability provides for efficient processing of high production volume MIM components.

Debinding And Sintering

Harber Industrial Group maintains a modern and well-equipped metrology department. Our advanced capabilities include, video measuring systems, CMM with scanning head, surface roughness and roundness testing equipment. Our metrology lab maintains and calibrates all of our in process measuring instruments and custom gages.

Powder Metrology and Materials Laboratories

Our materials laboratory has the capability to fully analyze and characterize the raw powders, feedstock and finished materials. Our lab is equipped for chemical analysis using ICP-MS, ICP-OES, UV-Vis, EDXRF, SEM-EDAX and Leco carbon and oxygen. Metallurgical analysis includes micrographic analysis, hardness testing (superficial & micro), tensile testing and salt spray. Feedstock characterization is carried out using capillary rheometry, DSC and TGA techniques. Our non-destructive testing capability includes magnetic particle, dye penetrant and Microfocus X-Ray techniques.
