Define the product
Dimensions, strength, appearance, standards, raw materials and target sales volume set the first constraints.
Draw the process
Receiving, preparation, dosing, transformation, curing or drying, control and storage should be represented before layout.
Calculate flows and utilities
Energy, water, air, people and material circulation influence area, safety and cost.
Choose maintainable equipment
Rated capacity, spare-part availability, maintenance simplicity and local skills matter as much as purchase price.
