- Material selection: Material selection involves selecting the appropriate raw materials required to manufacture the product. The choice of materials depends on the product’s requirements and specifications.
- Tooling design: Tooling design involves designing the tools required to manufacture the product. The tools may include jigs, fixtures, molds, and dies.
- Prototyping: Prototyping involves creating a sample of the product to test its design and functionality.
Production stage
The production stage is the main stage of the manufacturing process. It involves transforming raw materials into finished products. The production stage includes the following activities:
- Material handling: Material handling involves moving the raw materials from the warehouse to the production area. It also involves moving the finished products from the production area to the warehouse.
- Machining: Machining involves using machines and equipment to transform the raw materials into finished products. Machining includes cutting, drilling, milling, and shaping.
- Assembly: Assembly involves joining the different components of the product together to create a finished product. Assembly can be done manually or using automated machines.
- Quality control: Quality control involves inspecting the finished products to ensure that they meet the required quality standards. Quality control can be done manually or using automated machines.
- Packaging: Packaging involves wrapping and labeling the finished products for shipping and distribution.
Post-production stage
The post-production stage is the final stage of the manufacturing process. It involves activities that occur after the products have been manufactured. The post-production stage includes the following activities:
- Shipping and distribution: Shipping and distribution involve transporting the finished products to the customers or distributors. This may involve using trucks, ships, or planes.
- Maintenance: Maintenance involves ensuring that the machines and equipment are in good working condition. Regular maintenance can prevent breakdowns and prolong the life of the machines and equipment.
- Inventory management: Inventory management involves managing the inventory of raw materials and finished products. Effective inventory management can help reduce costs and prevent stockouts.
- Customer service: Customer service involves providing support to customers, such as handling complaints and providing technical assistance.
Mass Production
Mass production is a production concept that involves producing large quantities of identical products in a continuous flow process. This production concept is commonly used in industries that produce goods in high volumes such as automotive, electronics, and consumer goods.
Advantages of mass production are:
- Economies of scale: Mass production can take advantage of economies of scale, which means that the cost per unit decreases as the volume of production increases.
- High efficiency: The continuous flow process used in mass production ensures high efficiency as each worker performs the same task repeatedly, which increases their speed and accuracy.
- Standardization: Mass production allows for the standardization of products, which makes it easier to maintain quality control and reduces the chances of defects.
- Lower cost per unit: The high volume of production results in a lower cost per unit, which makes the products more affordable for consumers.
Disadvantages of mass production are:
- Lack of flexibility: Mass production is not flexible, and it is difficult to make changes to the production process or the product.
- High initial investment: Mass production requires a high initial investment in equipment, machinery, and production lines, which may be a barrier to entry for small businesses.
- Higher storage costs: Producing large quantities of products may result in higher storage costs, which can affect the overall cost of production.
Batch Production
Batch production is a production concept that involves producing a specific quantity of a product at one time. This production concept is commonly used in industries that produce goods in smaller volumes such as food and beverage, pharmaceuticals, and cosmetics.
Advantages of batch production are:
- Flexibility: Batch production is more flexible than mass production as it allows for changes to the production process or the product.
- Better quality control: Batch production allows for better quality control as each batch can be inspected and tested before it is released to the market.
- Reduced storage costs: Batch production allows for smaller quantities of products to be produced, which results in lower storage costs.
Disadvantages of batch production are:
- Higher cost per unit: Batch production has a higher cost per unit than mass production as it does not take advantage of economies of scale.
- Longer lead times: Batch production may have longer lead times as the production process is not continuous.
- Higher risk of errors: Batch production involves more set-up times and changes, which increases the risk of errors and mistakes.
Job-Shop Production
