Manufacturing is the process of creating products by transforming raw materials into finished goods. It is the backbone of modern industry, shaping how products are created and distributed globally since the Industrial Revolution. From the delicate artistry of skilled craftsmanship to the exacting accuracy of automated mass production, manufacturing processes have evolved to serve diverse industries and consumer demands. In this blog post, we’ll dive into the six major types of manufacturing processes that have shaped how goods come to be.
Job shop manufacturing
Job shop manufacturing is a versatile manufacturing process designed to create a diverse range of products tailored to individual orders.
This approach includes crafting each product according to specific customer requirements, involving utilizing specialized machinery and tools for production. Typically employed for crafting limited product batches or achieving high levels of customization, job shop manufacturing finds its application in various industries.
A prime example of a job shop manufacturer is a machine shop. Many metal components, including gears, shafts, and brackets, can be produced within a machine shop. Each piece is meticulously manufactured to precise customer specifications, utilizing distinct machines and tools customized to make each part.
It’s important to note that job shop manufacturing may have higher costs compared to alternative manufacturing methods like mass production. However, this approach offers unparalleled flexibility, enabling businesses to create products that cater to individual preferences and requirements. In summary, job shop manufacturing balances customization and cost-effectiveness, empowering companies to offer uniquely tailored products to their clientele.
| Pros: | Cons: |
| – Versatile production for various products. – Customizable to customer specs. – Suited for small batches, prototyping, and niche markets. | – Costlier than mass production. – Less efficient; each product made to order. – Complex management due to the diverse product range. |
Continuous process manufacturing
Continuous Process Manufacturing (CMP) is a type of manufacturing process where products are produced in a continuous flow.
This process is like a factory assembly line, but chemicals or food products are made instead of cars. The raw materials are continuously fed into the process, and the finished products are continually removed. This means the products are always being made, and there is no need to wait for a batch to finish before starting the next one.
CPM is often used to produce large quantities of products, such as chemicals, pharmaceuticals, and food products. It is a very efficient way to make large quantities of products.
| Pros: | Cons: |
| – Efficient: Immediate raw material use, swift product prep, cost-effective. – Consistent quality: Uniform conditions, crucial for standards like in pharmaceuticals. – Versatile: Meets diverse product demands, ideal adaptability. – Scalable: Adapts to demand, fuels growth. | – Costly setup and maintenance due to intricate equipment. – Complex, hard to control; sensitive to changes, requiring process expertise for quality. – Hazardous materials; requires essential safety measures. – Raw material wastage due to process issues; batch disposal risk. |
Discrete manufacturing
Discrete manufacturing is a type of manufacturing process that produces individual products or groups of products that are not identical.
This type of process is often used in the aerospace and defense industries. Discrete manufacturing is highly customizable and often used for producing unique products, like custom-made furniture.
In discrete manufacturing, the product is built one piece at a time or in small batches. This contrasts with continuous process manufacturing, where the product is produced continuously.
Discrete manufacturing is often used to produce complex products or require high customization. It is also used to produce products in small batches that are subject to change. Some examples are aircraft, cars, furniture, machinery, medical devices, electronics, toys, and jewelry.
| Pros: | Cons: |
| – Flexible: Adapts widely for fast responses to demand changes. – Customizable: Crafts tailored products for precise needs. – Efficient: Excels, particularly for small batches, reducing time and cost with dedicated machinery. | – Expensive: Costs more due to specialized machinery and tools. – Complex: Involves assembling products with many parts. – Time-consuming: Takes time for building, especially for larger or complex items. |
Repetitive manufacturing
Repetitive manufacturing is a process geared towards the mass production of identical products.
This type of process is often used in the automotive and electronics industries. The products are typically assembled on a production line, where a series of tasks are completed in the same sequence by employees and/or robots. This allows for the efficient production of large quantities of products.
Repetitive manufacturing is a highly efficient process for producing large quantities of identical products. However, it is not very flexible. This is because the production line is designed to produce a specific product, and changing the production line to produce a different outcome can be difficult.
It also requires high volumes of production to be profitable. This is because the costs of setting up and running the production line are fixed, so the manufacturer needs to produce a large number of products in order to make a profit.
Despite these limitations, repetitive manufacturing is a widely used manufacturing process for producing a variety of products, such as cars, electronics, appliances, toys, food, packaging, and clothing.
| Pros: | Cons: |
| – Efficient: Repetitive manufacturing excels for large quantities; optimized production. – Consistent: Ensures high product consistency; standardized process. – Cost-effective: Economical for bulk production; distributed setup costs. | – Limited flexibility: Repetitive manufacturing is inflexible; changing production lines for different products is tough. – High volume needed: Profitable with large production due to fixed setup costs; substantial output required. – Labor-intensive: Can demand much labor, especially for complex or customized items. |
Batch process manufacturing
Batch process manufacturing is a process in which the same set of operations are performed on a group of products before moving to the next batch.
It is often used to produce products that are customized or that have a high demand for variety. This process is a flexible manufacturing process that can be used to produce various products, from simple to complex. However, it is not as efficient as repetitive manufacturing for producing large quantities of products.
Batch process manufacturing is often used in the manufacturing of food and beverages, pharmaceuticals, chemicals, and cosmetics.
| Pros: | Cons: |
| – Flexible batch process: Adaptable for diverse products, quick response to demand. – Customizable: Tailors to customer needs, high degree of personalization. – Efficient: Streamlined for small batches, dedicated machinery cuts time and cost. | – Less efficient than repetition: this process requires setup and cleaning between batches; not ideal for large quantities. – Costlier than some: Batch process can be pricey due to specialized tools. – Complex control: Involves assembling multi-part products, challenging. |
3D Printing
3D Printing is a type of additive manufacturing technology that creates a three-dimensional object from a digital file.
The process works by depositing material until the object is complete. There are many different types of 3D printing technologies, but they all work on the same basic principle. The first step is creating a digital file of the object you want to print. This file can be made using a CAD software program.
The next step is to slice the file into thin layers. The 3D printer software does this. The thickness of the layers will vary depending on the type of 3D printer and the material being used. The 3D printer then deposits material onto a build platform, one layer at a time. The material is usually deposited in a liquid or powder form and is solidified by a laser or heat source. This process is repeated until the object is complete. The 3D printer then removes the object from the build platform.
3D printing is a versatile manufacturing process that can be used to create a wide variety of objects, from simple prototypes to complex medical devices. It is also a very flexible process, and it can be used to produce objects in small or large quantities.
| Pros: | Cons: |
| – Flexibility: Produces diverse objects, from prototypes to medical devices. – Customization: Tailored to customer specs. – Efficiency & Cost: Cost-effective for small batches. | – Speed: 3D printing slow, notably for large objects. – Accuracy: Less precise than traditional methods. – Material limit: Limited material options for 3D printing. – Post-processing: Often needs sanding, painting, etc. |
In conclusion, manufacturing processes have evolved and will continue to. Each of the processes has its strengths and challenges. This is where manufacturing Enterprise Resource Planning (ERP) systems play a pivotal role in overcoming these challenges. An ERP creates synergy between manufacturing processes by aiding resource allocation, production management, and supply chain coordination. For Job Shop Manufacturing, an ERP aids in resource allocation and scheduling. In CMP, an ERP streamlines material and production management. In Discrete Manufacturing, an ERP handles intricate production variables. Repetitive Manufacturing benefits from ERP’s supply chain coordination. For Batch Process Manufacturing, an ERP perfects complex workflows. Even in 3D Printing, an ERP can manage material stocks and order flows.
