How to Calculate Machine Production Capacity (BPH)?

When evaluating the efficiency of an industrial machine, one of the most important performance indicators is its production capacity, often expressed as BPH (Bottles Per Hour) or units per hour. Understanding this calculation helps determine whether a machine can meet production demands, optimize scheduling, and ensure cost efficiency.

What Is a Bottle Blowing Machine?

A bottle blowing machine is a piece of industrial equipment used to produce hollow plastic containers, most commonly PET bottles for beverages, detergents, and other liquid products. The process involves transforming preforms—small, tube-shaped pieces of plastic—into fully formed bottles through heat and air pressure.

What Industries Use Injection Molding?

Injection moulding is one of the most widely used manufacturing technologies in the modern industrial world. By melting thermoplastic or thermosetting materials and injecting them into a mould cavity, this process enables the mass-production of consistent, durable plastic parts with excellent precision.

How Long Does Injection Molding Take?

Injection molding is a highly efficient manufacturing process where molten plastic is forced into a mold cavity, cools and solidifies, and then the finished part is ejected for the next cycle. The total time for one full cycle—commonly referred to as the “cycle time”—is critical for production planning, cost estimation, and process optimization.
