[Development Case] Near-Net Shape Manufacturing of Injector Components

[Development Case] Near-Net Shape Manufacturing of Injector Components

Improved yield through non-cutting of outer diameter by increasing forging accuracy! A case study of flange forming without intermediate annealing.

We would like to introduce a development case of near-net-shape manufacturing for injector components. In conventional products, processes such as cleaning, annealing, shot blasting, and oiling were performed in intermediate processing. The developed product implements flange forming without intermediate annealing, eliminating the intermediate processing. The cost of the developed product is 80% compared to 100% for the conventional product. Please feel free to contact us when you need our services. 【Development Objectives】 ■ New Method: Through-hole for small diameter deep holes (without annealing) ■ Improved Yield: Elimination of external diameter cutting due to increased forging precision ■ Novelty: Flange forming without intermediate annealing *For more details, please download the PDF or feel free to contact us.

Automotive parts with the top and bottom surfaces of molybdenum steel machined flat.

Automotive parts with the top and bottom surfaces of molybdenum steel machined flat.

Introducing our processing achievements of flatting two surfaces with different areas through double-sided grinding!

We would like to introduce automotive parts that have been flat ground on both sides using double-sided grinding on the top and bottom surfaces of molybdenum steel. For hardened materials, we achieve flatness on two surfaces with different areas through double-sided grinding. The thickness tolerance is within ±10um, and we can handle a production lot of 80,000 pieces per month. Our double-sided grinding and lapping technology does not use magnets for workpiece fixation; instead, we perform grinding and polishing by sandwiching the workpiece between upper and lower rotating grinding wheels, allowing us to accommodate various materials, including non-magnetic and difficult-to-machine materials. Please feel free to consult us when needed. 【Product Specifications】 ■Material: SCM415H (Chromium Molybdenum Steel) ■Processing Type: Grinding ■Dimensions & Tolerance: φ60, Thickness: ±10um or less ■Industry: Automotive (Washer Parts) ■Production Lot: 80,000 pieces/month *For more details, please refer to the related links or feel free to contact us.
