Standard Product Development Cycle?
Hetian's standard development cycle adapts dynamically to product complexity, with three core phases: design verification, prototype trial, and batch validation：
Phase 1: Design Stage (7-15 days)
? Technical Feasibility: Rapid CAD design and simulation using mature processes (e.g., aluminum forging, stamping).
? Prototyping: Initial samples via manual/RPT (Rapid Prototyping Tech, e.g., 3D printing) for functional validation.
Phase 2: Validation Stage (15-30 days)
? Performance Testing: Fatigue tests and dimensional inspection in CNAS-accredited labs, ensuring compliance (e.g., German OEM standards).
? Process Optimization: Pilot runs to refine mold parameters and line layout, mitigating mass-production risks.
Phase 3: Batch Validation (10-15 days)
? Supply Chain Synergy: Concurrent raw material sourcing and supplier development (e.g., rubber damper partners) to compress lead times.
? Mass-Production Launch: PPAP (Production Part Approval Process) documentation ensures seamless transition post-customer approval.
? Critical Factors: Cycles may extend to 3 months for special materials (e.g., imported aluminum alloys) or complex structures (e.g., multi-link suspensions).
Major Project Development Cycle?
For OEM projects, Hetian employs a "Simultaneous Engineering + Phased Validation" model with the following workflow:
Phase 1: Simultaneous Engineering (3-6 months)
? Requirements Alignment: Jointly define technical specs with OEMs (e.g., load requirements for lightweight aluminum forgings), reducing sourcing decision time.
? Co-design: 65 engineers participate in OEM's Digital Mock-Up (DMU) reviews to optimize structural compatibility.
Phase 2: Road Testing & Validation (2-4 months)
? Prototype Iteration: A-Sample (functional) → B-Sample (performance) → C-Sample (process stability) validation.
? Environmental Testing: Simulate extreme conditions (-40°C~120°C/salt spray) to ensure 10-year/200,000-km lifespan compliance.
Phase 3: Production Ramp-up (3-6 months)
? Line Expansion (if required): Install automated forging lines and assembly equipment.
? SOP Launch: Pass OEM Run-at-Rate Audit for zero-defect delivery.
Case Study: Hetian delivered an aluminum front control arm for an EV OEM in merely 8 months, cutting mold commissioning time by 30% via simultaneous engineering.
Key Factors for Cycle Variance
Technology Maturity: Standard products leverage existing process libraries (e.g., rubber compound formulas, 27-year aftermarket database), while major projects require new material/process R&D (e.g., high-strength aluminum forgings).
Resource Commitment: Major projects need cross-functional teams (Procurement/Legal for supply chain compliance), versus standalone tech teams for standard products.
Validation Depth: OEM projects mandate full-vehicle durability tests (100,000-km road trials), exceeding lab sampling for standard parts.
