- Light Commercial Vehicles (LCV)
- Parts for electric vehicles:
- PHEV (Plug-in Hybrid Electric Vehicle)
- HEV (Hybrid Electric Vehicle)
- BEV (Battery Electric Vehicle)
- Parts for passenger cars.

Advantages and disadvantages of OEM parts

Differences between OEM, ODM, and OBM in industrial manufacturing
OEM
OEM (Original Equipment Manufacturing) refers to manufacturers who produce goods based on the customer’s design and sell them under the customer’s brand name. OEM services typically cover the entire process from solution research, material sourcing, prototyping, to final production.
Products commonly produced under the OEM model include: consumer electronics, household appliances, automotive and motorcycle parts, bicycle components, fashion accessories, furniture, and more.

ODM
ODM (Original Design Manufacturer) refers to manufacturers with the capability to design products according to customer requirements and launch them under the customer’s brand name.
ODM services include end-to-end solutions from research and design to complete production. Products typically made under the ODM model include clothing, footwear, cosmetics, home décor, and more.

OBM
OBM (Original Brand Manufacturing) refers to manufacturers who develop and produce products under their own brand name.
OBM companies handle the full value chain – from R&D, design, production, to marketing and branding. This allows them to fully control the production process, pricing, and product quality.
Products made under the OBM model include consumer electronics, navigation devices, IoT products, medical equipment, industrial and electronic devices, and more.

Which business model should you choose?
The choice between OEM, ODM, and OBM depends on multiple factors: product type, production and design capabilities, brand objectives, business strategy, financial resources, and human capital.
- OEM: Best suited for businesses that want to produce products based on their own design, focusing on brand building and sales without heavy investment in production facilities.
- ODM: Suitable for businesses that want custom products but lack design and manufacturing capabilities, allowing them to focus on marketing, sales, and brand growth.
- OBM: Ideal for businesses with strong financial resources, professional staff, in-house design and production capacity, and a long-term strategy to develop exclusive brands and maximize profits.
In summary, choosing the right model depends on each company’s needs, capabilities, and limitations, helping businesses optimize resources, improve manufacturing efficiency, and enhance competitiveness in the market.
