TDG Holding Co., Ltd. (600330.SS): How It Works

• Core manufacturing platforms: ferrite sheet and soft ferrite core production lines, high‑frequency magnetic component fabs, microwave module assembly, and precision equipment lines for powder processing and crystal growth.
• R&D and process engineering: in‑house capabilities for ferrite formulation, sapphire crystallization and piezoelectric material optimization-supporting product differentiation for NFC, wireless charging, RF front‑end and sensor applications.
• Sales & channel model: direct OEM/ODM contracts with consumer electronics makers and tier‑1 automotive suppliers, plus project-based equipment sales to materials and crystal producers.

• Magnetic materials and antenna substrates - sale of ferrite sheets (used in NFC antennas) and soft ferrite cores (wireless chargers): priced and sold by volume/area for handset and wearable makers; typically recurring high-volume orders from consumer electronics supply chains.
• Electronic devices & smart equipment - finished modules and smart devices for end markets (automotive electronics modules, charger modules, consumer accessories) sold to OEMs and distributors.
• Electronic Manufacturing Services (EMS) - contract manufacturing, assembly, testing and small-series production runs leveraging TDG's factories; margin from labor, overhead recovery and value‑added integration services.
• High‑frequency and microwave components - sale of inductors, transformers, RF modules and filters used in telecom, automotive radar and IoT devices; sold as components and integrated submodules.
• Powder materials and crystal process equipment - sale of fabrication equipment (powder processing, crystal growth furnaces and process lines) to materials producers, plus after‑sales services and spare parts.
• Sapphire and piezoelectric products - sale of sapphire crystal substrates and piezo‑electric crystal materials for sensors, optics and timing devices; often sold at premium prices for high‑reliability industrial/automotive use.

• Gross margin drivers: product mix (materials and components have higher gross margins than EMS), utilization of production lines, and value added from proprietary ferrite formulations and crystal growth IP.
• Cost structure: raw materials (metal oxides, sapphire feedstock), energy (high‑temperature furnaces), labor and depreciation of capital equipment for precision process lines.
• R&D and capex: R&D investment typically ~4-6% of revenue to support new ferrite grades, RF modules and crystal process yields; capital expenditures prioritize capacity for high‑precision crystal and powder equipment.
• Client concentration and contract structure: long‑term supply agreements with OEMs and project-based equipment sales - recurring material/component orders provide steady cash flow while equipment deals and EMS projects create lumpier but higher‑margin revenue.

• Inventory intensity is moderate-to-high due to raw material buffering (metal oxides and sapphire feedstock) and finished component stocking for OEM delivery schedules.
• Receivables follow OEM payment cycles; EMS and equipment sales may require milestone payments that improve cash flow timing when front-loaded.

• Upgrading ferrite formulations to higher‑value NFC and EMI suppression products with better margins.
• Expanding sapphire and piezo product mix into higher‑margin industrial and automotive segments.
• Improving manufacturing yields and furnace energy efficiency to lower per‑unit costs in crystal growth and powder processing.
• Cross‑selling modules and EMS to existing materials customers to deepen account value.
