Subassembly assembly is an industrial process by which various parts or components are joined together to form a larger unit. This is a widely used method in the manufacturing industry because it enables significant time and cost savings and, in general, optimizes the mass production process.
At Bericht we are experts in the manufacturing of metal parts for different industries, and therefore, in this comprehensive guide, we explain what this process entails and why it is beneficial to increase production.
What is subassembly assembly?
The subassembly assembly process consists of the joining of pre-existing components to form a part or complete product. Instead of manufacturing each piece from scratch, previously fabricated or acquired subgroups are used, which are then assembled to create the final structure.
This method allows for more efficient production by leveraging existing parts and reducing the need to manufacture individual components at each stage. It also facilitates product modularity and customization by allowing the combination of different elements according to the specific needs of each job.
Key strategies in subassembly assembly
There are several strategies that optimize efficiency and flexibility in industrial production through subassembly assembly. One of the most notable is modularization, which involves dividing a product into independent modules or subgroups that can be easily assembled and disassembled. This facilitates manufacturing, transportation, and maintenance of the products, as well as allowing greater customization according to customer needs.
Another important strategy is the standardization of components, which involves using common parts and subassemblies across different products. This reduces production costs and simplifies inventory management by minimizing the variety of parts needed. Standardization also facilitates the integration of new components and the upgrading of existing products.
Assemble-To-Order (ATO)
Assemble-To-Order, (ATO), is a strategy that allows for greater customization and flexibility in production. Instead of assembling products in mass and maintaining an inventory of finished goods, companies keep individual components in stock. When a customer order is received, products are assembled according to the exact specifications of the order.
This strategy reduces the costs associated with inventory storage and minimizes the risk of product obsolescence. It also enables a quick response to changing market demands and the ability to offer customized products to customers.
It is especially beneficial in industries where customization is key, such as the manufacturing of medical equipment, custom automobiles, and electronic products.
Related manufacturing processes
There are several processes involved within the subassembly assembly system that prepare components for final assembly.
- Casting: the process of pouring molten metal into a mold to create solid parts with specific shapes. This method is used to manufacture metal components such as housings, bases, and other structural elements.
- Machining: involves shaping components using cutting tools such as lathes, milling machines, and drills. This process is used to create parts with tight tolerances and precise finishes, such as gears, shafts, and brackets.
- Assembly: the final stage where subassemblies and individual components are joined to form the complete product. Various assembly techniques can be used, such as welding, riveting, screwing, or bonding, depending on design requirements and product specifications.
These procedures are part of the assembly method as they prepare the components for integration into the final unit.
Advantages of subassembly assembly
This manufacturing method provides numerous advantages that lead many companies to incorporate it into their production systems.
Here are the most notable ones:
- Efficiency and cost reduction: allows for more efficient production by reducing assembly times and costs associated with handling and transporting individual components.
- Greater flexibility and customization: by assembling subassemblies instead of individual components, companies can more easily adapt to customer-specific needs and make personalized adjustments to products.
- Improved product lifecycle management: by simplifying the assembly process and reducing dependence on individual components, companies can enhance lifecycle management from design through manufacturing and maintenance.
- Improved customer satisfaction: by offering more customized and tailored products to individual customer needs, customer satisfaction can be significantly improved and business relationships strengthened.
The subassembly assembly process represents a smart option for assembly companies seeking optimization and agility in their processes. This methodology not only saves time and resources but also improves operational efficiency and market competitiveness.
