Yes, it is common for manufacturing plants, including those producing fiber optic handheld laser welding machines, to purchase the components needed for production.
Factories usually source raw materials, electronic components, mechanical parts and other necessary items from different suppliers or distributors.
Purchasing components allows factories to control the quality and specifications of materials used in the manufacturing process. Additionally, it provides the flexibility to select a supplier based on factors such as cost, reliability, and proximity. Many manufacturing operations have dedicated procurement or supply chain management teams responsible for sourcing and acquiring required components.
To sum up, it is completely feasible for factories to purchase their own components to produce fiber optic handheld laser welding machines, which is a standard practice in the manufacturing industry.
