1. Requirement
Develop the tooling from complete drawings, protect the fit-critical outer geometry and reach the first production shot within the customer's 30-day project window.
Documented Project Record · Automotive / EV
EV motor housing mold with fit-sensitive outer surfaces
The customer supplied complete product drawings. The recorded targets were a 30-day delivery window, a minimum mold-life requirement of 100,000 shots and controlled fit where the housing met the vehicle body structure.
Direct answer
What was recorded?
Yuda built the mold from the customer's drawings within the recorded 30-day window. The molded housing met the specified body-fit requirements and passed customer acceptance on the first submission.
| Input | Complete customer product drawings |

| Application | Automotive / electric-vehicle motor housing |
| Delivery record | Within 30 days |
| Mold-life requirement | 100,000 shots minimum |
| Recorded result | First-submission acceptance |
Requirement, challenge and outcome
2. Manufacturing challenge
The outer surface had to align with the vehicle body structure. Assembly fit and the visible transition between parts were key approval points.
3. Recorded outcome
The mold was delivered within the recorded window. The housing met the drawing-based fit requirement and passed customer acceptance on the first submission.
Scope note: This is a project record, not a universal tolerance claim. A new automotive or EV project is reviewed against its drawing, material, assembly, validation and production requirements.
What a buyer should include in a similar RFQ
Identify every mating interface
Mark the body surfaces, mounting points and gap conditions that control assembly acceptance.
Share the validation standard
State the required dimensional report, sample quantity, fit check and any customer-specific approval process.
Separate mold life from part approval
Mold-life requirements influence tooling decisions, while part approval depends on the drawing, resin, process window and assembly test.
