No, not all products are manufactured the same way. The manufacturing process depends on the product type and the manufacturer. For example, some products are made by hand while others are made by machines. Some products are made in small batches while others are mass-produced. The manufacturing process can also vary depending on the materials used to make the product.
For example, a car is manufactured differently than a piece of furniture. Cars are typically mass-produced using an assembly line process while furniture is often made by hand or in small batches!
So yeah, hope that helped!
