In the global fields of precision electromechanics, medical devices, new energy vehicle systems, and high-end industrial automation, actuators are often the core components that dictate the overall system’s performance metrics and reliability lifeline. Facing increasingly complex electromechanical integration challenges, multinational project directors and Global Supply Managers (GSM) seeking OEM/ODM custom partners focus not only on contract manufacturing capabilities, but more importantly on whether the supplier possesses rigorous advanced engineering planning, cross-disciplinary technical co-design, and validation management systems conforming to international standards.
Shih Shin Technology has been deeply involved in the electromagnetic actuation field for decades, establishing a standardized, highly transparent, and agile custom project development system. From initial technical specification review (SOR Review), spanning EVT/DVT/PVT validation phases, all the way to mass production and continuous improvement, Shih Shin Technology ensures projects are delivered on time and within specifications through rigorous milestone management. This article provides a comprehensive overview of Shih Shin Technology’s standard OEM/ODM project development process.
1. Five Major Engineering Milestones Across the Project Lifecycle
Shih Shin Technology adheres to internationally recognized Advanced Product Quality Planning (APQP) standards, dividing project development into five interconnected core phases:
Shih Shin Technology OEM/ODM Project Engineering Milestones Architecture
| Development Phase | Core Tasks & Engineering Activities | Key Phase Deliverables | Typical Lead Time |
|---|---|---|---|
| Phase 1: Requirements Review & DFM | Customer SOR/RFQ review, 3D magnetic circuit finite element analysis (FEA), mechanical design for manufacturability (DFM) | Engineering assessment report, feasibility sign-off, preliminary 2D/3D concept drawings | 1–3 business days |
| Phase 2: EVT Engineering Validation Samples | Rapid prototyping, modular coil winding, CNC plunger prototyping, baseline force and temperature rise measurements | EVT samples (5–10 pcs), preliminary electrical characteristics test report | 2–3 weeks |
| Phase 3: DVT Design Validation Phase | Tooling fabrication, fully functional sample trial run, extreme environmental reliability testing (thermal shock, vibration, endurance life testing) | DVT samples (50–100 pcs), comprehensive reliability test report (TR), specification freeze | 4–6 weeks |
| Phase 4: PVT Production Validation Phase | Mass production tooling/fixture buy-off, Standard Operating Procedure (SOP) finalization, process capability analysis (C_pk ≥ 1.33) | PVT pilot run samples, PPAP Level 3 documentation package, Control Plan | 2–3 weeks |
| Phase 5: SOP Mass Production | Automated assembly line mass production, 100% final electrical hipot testing, end-to-end SPC statistical process monitoring | Mass shipment, Certificate of Analysis (COA) per batch, capacity ramp-up, and continuous improvement | Mass production cycle |
2. Taiwan HQ Technical Core: FEA Magnetic Circuit Simulation & DFM Co-Design
During the project initiation phase, the Shih Shin Technology Taiwan R&D team directly participates in customer architecture discussions, delivering front-end co-design value:
1. 3D Magnetic Circuit Finite Element Analysis (FEA)
Prior to committing to any physical metal machining, Shih Shin Technology’s senior magnetic engineers utilize specialized simulation software, inputting target ampere-turns, magnetic steel B-H magnetization curves, and pole face geometries:
- Predictive Attraction Force Curves: Accurately simulate electromagnetic force vector distribution across the full 0mm to 20mm stroke of the plunger, proactively eliminating blind spots where long-stroke force may fall short.
- Saturation and Flux Leakage Suppression: Identify magnetic saturation hotspots in the housing early, optimizing wall thickness or conical geometry to reduce stray flux leakage and maximize material energy efficiency.
2. DFM Review (Design for Manufacturability)
When reviewing drawings, Shih Shin Technology engineers actively assist clients in auditing mechanical mating tolerances, assembly interference, and material selection:
- Recommend controlling plunger concentricity within the most cost-effective and highly reliable range of ± 0.005mm.
- Optimize housing mounting flange thickness and chamfers to enhance stamping flatness and prevent deformation during downstream assembly fastening.
3. Stringent Quality Validation and Reliability Laboratory Assurance
Upon entering the DVT and PVT phases, the Shih Shin Technology quality assurance team validates the samples’ extreme environmental endurance using a comprehensive suite of high-specification testing equipment:
Pre-Delivery Comprehensive Reliability Testing Matrix
- 1 Million to 10 Million Cycles Extreme Fatigue Life Testing:
On multi-station automated endurance test benches, continuous reciprocating action is performed under rated load and maximum operating frequency, continuously monitoring stroke force degradation, response time drift, and bushing wear in real time. - Tri-Axial Random Vibration and Shock Testing:
In accordance with ISO 16750 or MIL-STD-810G standards, simulating transportation and extreme operational vibration conditions to verify bolt anti-loosening and coil lead wire stress relief without risk of short circuits. - High/Low Temperature Alternating Damp Heat and Thermal Shock Testing:
Undergoing hundreds of thermal cycles in a -40°C to +150°C chamber to verify coefficient of thermal expansion (CTE) matching across materials, eliminating plunger jamming or potting compound cracking. - Hipot Insulation and Microamp-Level Leakage Current 100% Inspection:
100% end-of-line testing conducted under 2,500V AC high voltage, requiring insulation resistance ≥ 1,000 MΩ to ensure absolute electrical safety in medical-grade and automotive high-voltage environments.
4. Agile Project Management and High-Transparency Communication Mechanism
To ensure smooth progress on international projects, Shih Shin Technology assigns a Dedicated Project Manager (PM) and Field Application Engineer (FAE) to form a “dual-core service team”:
International Project Delivery Commitments
- 24-Hour Rapid Technical Response: Upon receiving a client’s RFQ or specification drawings, preliminary engineering review and feasibility evaluation are completed and returned within 24 hours.
- Transparent Schedule Tracking (Weekly Gantt Chart): Providing weekly engineering Gantt chart updates clearly detailing tooling fabrication, sample testing, and approval milestones, proactively identifying potential risks and providing preventive countermeasures.
- Full Lifecycle Quality Traceability for Mass Production: Laser-marking unique batch serial numbers on product housings, accompanied by comprehensive Certificates of Conformance (COC) and statistical process data to fully support client audit requirements across global markets.
