Andon is a visual management tool used in the Toyota Production System (TPS) and other lean manufacturing systems to indicate the status of a production line or work process. The word “andon” comes from the Japanese word for “lamp,” which was originally used to signal problems in the production line. Andon systems typically consist of … Continued

The Toyota Way – 14 principles

14 Principles of “The Toyota Way” 1. Base your management decisions on a long-term philosophy, even at the expense of short-term financial goals. 2. Create a continuous process flow to bring problems to the surface. 3. Use “pull” systems to avoid overproduction. 4. Level out the workload (work like the tortoise, not the hare). 5. … Continued

Theory of Constraints (TOC)

The Theory of Constraints (TOC) is a management philosophy developed by Eliyahu M. Goldratt in the 1980s. It is based on the idea that in any organization or system, there is always at least one constraint that limits its performance. The goal of TOC is to identify and manage these constraints to improve the overall … Continued

Banbury Internal Rubber Mixer

A Banbury mixer is a type of internal mixer used in the rubber industry for mixing and kneading rubber compounds. It was invented by Fernley H. Banbury in 1916. The Banbury mixer consists of two large rollers that rotate in opposite directions and a chamber between them where the rubber material is mixed. The rubber … Continued

Best Elastomer for Abrasion Resistance

The best abrasion resistant elastomer depends on the specific application and the conditions under which it will be used. Here are some commonly used abrasion-resistant elastomers and their properties: Nitrile rubber (NBR): NBR is a synthetic rubber that is commonly used in industrial applications due to its high resistance to abrasion, oil, and chemicals. It … Continued

Molecular Slippage and Carbon Black Reinforcement

Molecular slippage is a phenomenon that occurs when a molecule moves through a narrow channel or pore. It was first described by Dr. Ross E. Dannenberg, a researcher at the National Institutes of Health (NIH), in the early 1980s. According to Dannenberg, when a molecule moves through a narrow channel or pore, it can sometimes … Continued

Sound Dampening Properties of Rubber

Rubber is a popular material for sound dampening due to its unique properties. The sound dampening properties of rubber are primarily due to its ability to absorb vibrations and convert them into heat energy. When sound waves hit rubber, the rubber absorbs some of the energy from the wave and converts it into heat, which … Continued

Central Limit Theorem – Goodyear Quality

The Central Limit Theorem (CLT) is a fundamental concept in probability theory and statistics. It states that if you take a large enough sample of independent and identically distributed random variables from any distribution with a finite mean and variance, then the sample mean of those variables will approach a normal distribution as the sample … Continued
