A parts supplier is a company or individual that provides components or materials needed for manufacturing or repairing products. These parts can range from small items like screws and bolts to larger components like engines or electronic circuits. Parts suppliers play a crucial role in various industries, including automotive, electronics, and machinery. Typically, parts suppliers maintain a stock of items and may also offer custom solutions to meet specific needs. They often work closely with manufacturers, ensuring that the right parts are available at the right time to keep production running smoothly. This relationship is vital for efficiency and quality in the supply chain.
