For any thermoforming company, timing is everything. After all, you want your part when you want it. At ThermoFab, we understand this. This is why we follow The Theory of Constraints (TOC) business management philosophy called Drum-Buffer-Rope (DBR), which was developed by Dr. Eli Goldratt, author of The Goal: A Process of Ongoing Improvement; It's Not Luck; Critical Chain; and Necessary But Not Sufficient.
Thermoforming Processes: Timing is Everything

DBR controls the flow of materials through the plant so that products are produced according to market demand with a minimum of manufacturing lead-time, inventory and operating expenses.
Drum, Buffer, Rope Definitions
- Drum
- Constraints or bottlenecks in the process. This is what is being managed to ensure a smooth flow.
- Buffer
- A protection against Murphy. This is the time provided for parts to reach the protected area. The protected areas are the Drum, the due dates and the assemblies of constraint parts with non-constraint parts.
- Rope
- A schedule for releasing raw materials to the floor. The Rope is derived according to the Drum and Buffers; its mission is to ensure the proper subordination of the non-constraints.
The DBR technique enables companies to maximize a Capacity Constraint Resource and use time buffers to create schedules that help deliver products on time.
Drum-Buffer-Rope is based on the TOC logistics approach and its five steps of focusing:
- Identify the System's Constraint(s).
- Decide How to Exploit the System's Constraint(s).
- Subordinate Everything Else to the Above Decisions.
- Elevate the System's Constraint(s).
- If, in the Previous Steps, a Constraint Has Been Broken, Go Back to Step One, but Do Not Allow Inertia to Cause a System's Constraint.
