XS Cooler - Xinsheng Heat Exchanger

How We Work with OEMs

Program Execution

A Clear Path from RFQ to SOP

We follow a structured program process from RFQ to prototype, validation, and SOP. The goal is to reduce rework, shorten validation cycles, and make quality auditable at every stage.

Development Process

1

Customer Input

Technical parameters, outline drawings, operating conditions

  • • Specification review
  • • Application requirements
  • • Packaging constraints
2

Solution Design

Design & calculation, DFMEA, 3D/2D drawings

  • • CFD thermal modeling
  • • Structural analysis
  • • Design for manufacturability
3

Design Review

Customer design review, technical proposal, test plan

  • • Design validation
  • • Test planning
  • • Cost optimization
4

Prototype Build

Production drawings, BOM & process files, quality control plan

  • • Rapid prototyping
  • • Initial samples
  • • Process validation
5

Verification

Cooling performance test, reliability test, corrosion test

  • • Thermal testing
  • • Vibration endurance
  • • Salt spray testing
6

First Article Approval

Full inspection report, test reports, tests on host

  • • PPAP documentation
  • • Customer approval
  • • Production readiness
7

Mass Production

Updated MPP & CP, lessons learned, updated FMEA

  • • Serial production
  • • Continuous improvement
  • • Quality monitoring
Documentation

What You Receive

We provide comprehensive documentation throughout the development and production process to support your qualification requirements and maintain full traceability.

  • Technical proposal and drawings (2D/3D)
  • DFMEA / PFMEA (upon request)
  • Validation plan and test reports
  • 100% leak and pressure test records with traceability
  • PPAP-style documentation package (upon request)
  • Material certifications and traceability

Cross-Functional Ownership

Programs are supported by Engineering, Quality, Manufacturing, Program Management, Supply Chain, and Customer Support — aligned to customer control plans and launch requirements.

Program Manager

Single point of contact for project coordination

Application Engineer

Technical design and optimization

Quality Representative

Quality assurance and documentation

Manufacturing Lead

Production planning and execution

Supply Chain

Engagement Model

Our structured approach ensures alignment from initial intake through production and ongoing support.

1

Program Intake

Operating conditions, packaging, risk review

2

Architecture Selection

Bar&Plate vs Tube&Fin, modular vs standalone

3

Prototyping & DFM

Samples, test plans, manufacturability review

4

Qualification

Testing, verification, documentation package

5

Ramp & Sustain

Serial production, ECN management, support

Communication & Escalation

We define response SLAs and escalation paths for quality and delivery topics. Corrective actions follow structured 8D practices when applicable.

  • • Defined response timelines for inquiries
  • • Clear escalation paths for urgent issues
  • • 8D methodology for corrective actions
  • • Regular status updates and reviews
