It often occurs after various manufacturing processes like machining, casting, or molding. Assembly lines or workstations streamline this process, ensuring efficiency and consistency. Depending on the complexity of the product, assembly can range from manual to automated.

Manufacturing processes by scale of production

• Job shop manufacturing. In job shop production processes, products are typically manufactured individually or in small series, often ranging from one to two dozen per month. This approach allows for a wide range of products to be produced, using universal equipment, devices, cutting, and measuring tools for general purposes. Workplaces are grouped based on technologically homogeneous operations, with no specific operations assigned to individual employees. Employees are highly qualified to handle the diverse nature of work performed. However, detailed development of the technological process for manufacturing the product is limited. Planning, regulation, and accounting focus on the entire product or its large units (subassemblies), resulting in relatively low costs for preparing production of new products. This type of one-off manufacturing process is common in pilot plants that produce complex products and special-purpose systems.
• Batch (or serial) manufacturing. Serial production processes involve the periodic production of products in batches, with small batches typically ranging from several hundred to large-scale batches of 2-5 thousand pieces per month. While there is a limited range of products manufactured, universal and specialized equipment, attachments, finishing, and measuring tools are used. Workplaces are grouped based on technological and organizational principles, with a limited number of different operations assigned to each workplace. Employees have a moderate level of qualification, and there is detailed development of technological processes. Planning, rationing, and accounting focus on the units and details of the product, resulting in relatively high costs for preparing production of new products compared to single-type production. This type of manufacturing process is common in process manufacturing as well as in factories producing sophisticated products and special-purpose systems that undergo frequent design changes.
• Mass production. Mass production processes involve the manufacture of products in large quantities, using specialized and special equipment, devices, and tools. Workstations are arranged according to the flow of the technological process, with each workstation specializing in performing one operation. The technological process is developed in detail, with planning, rationing, and accounting focusing on the details and operations. Workers may have lower qualifications, and preparation for producing new products requires the highest costs compared to other types of production. This type of manufacturing process is predominantly used in producing consumer goods.

Manufacturing processes by the nature of the product

• Discrete manufacturing. Discrete manufacturing involves the production of distinct items or products that are easily identifiable as separate entities. These products are typically assembled from individual components or parts through assembly or fabrication processes. Examples of discrete manufacturing include the production of automobiles, consumer electronics, furniture, machinery, and toys. In discrete manufacturing, each unit produced is unique and can be customized to meet specific customer requirements. This type of manufacturing is often characterized by high variability, short production runs, and the use of assembly lines or workstations to assemble components into finished products.
• Process manufacturing. Process manufacturing, on the other hand, involves the production of goods that are produced through a series of continuous or sequential processes. Unlike discrete manufacturing, where products are assembled from individual components, process manufacturing involves mixing, blending, or transforming raw materials or ingredients to create the final product. Examples of process manufacturing industries include chemical processing, food and beverage production, pharmaceutical manufacturing, and oil refining. Process manufacturing is characterized by standardized recipes or formulations, continuous production flows, and the use of specialized equipment such as reactors, mixers, and distillation columns. Products manufactured through process manufacturing often undergo physical or chemical changes during production and are typically produced in large quantities.
