Manufacturing Case Overview
Jinhua Machinery manufactures drawing-based automotive precision components. This case concerns a finished retaining washer specified in carbon steel per GB/T 1591-2018 Grade Q460C. The component is evaluated against the approved drawing for dimensions, flatness where specified, edge and burr condition, corrosion protection, and reporting requirements. It is not presented as steel stock, a raw-material supply offer, or a standard replacement item.

Engineering Requirements
The released drawing governs the acceptance criteria for this component. The review scope includes:
- dimensional control for the finished retaining washer;
- flatness requirements where they are defined by the approved drawing;
- controlled edges and burr limits; and
- corrosion-protection requirements and the agreed acceptance method.
No customer name, vehicle system, numeric tolerance, or inspection result is published on this page.
Manufacturing Considerations
The production route is determined based on drawing requirements, material characteristics, annual volume and customer specifications.
Before quotation, Jinhua Machinery reviews the drawing revision, material callout, critical characteristics, datum requirements, edge condition, corrosion-protection specification, quantity, traceability, and report expectations. This case does not claim stamping, forging, machining, or heat treatment because the approved public evidence does not confirm a specific production route.
Quality Control
Quality planning follows the approved drawing and agreed control plan. The review can include dimensional inspection, material verification, surface-quality inspection, and drawing-compliance checks. The method, sampling plan, instrument or gauge, acceptance criteria, and report format are confirmed for each project; this page does not claim case-specific results that have not been approved for publication.
