Flow Behavior of Rubber Compounds

  Rubber compounds are complex mixtures of rubber, fillers, oils, curatives, and other additives. Such experimental studies as have been done, have, of necessity, been confined to a few specific, and usually simple, compounds. Mathematical models of rubber flow, have, therefore, to make a number of simplifying assumptions in order to reduce their complexity, and to … Continued

A3 Lean Tools

A3 is a problem-solving tool and methodology that is part of the Lean management approach. It gets its name from the paper size, which is commonly used for the document or report that summarizes the problem-solving process. The A3 process involves creating a visual representation of the problem and potential solutions on a single sheet … Continued

Lean marketing

The principles of lean manufacturing can be applied not only to manufacturing processes but also to sales and marketing processes. Here are some of the key lean principles that can be applied to sales and marketing: Customer value: In lean sales and marketing, the focus is on delivering value to the customer. This means understanding … Continued

Rubber: Shear Thinning Flow

Shear thinning fluids are fluids that exhibit a decrease in viscosity as the shear rate increases. In other words, the fluid becomes less viscous and flows more easily when it is subjected to higher rates of shear stress. Rubber is an example of a shear thinning material. When rubber is subjected to shear stress, the … Continued

Flow behavior of rubber compounds in Extrusion

Rubber compounds exhibit unique flow behavior during extrusion due to their viscoelastic properties. When a rubber compound is subjected to shear stress during extrusion, it experiences both viscous and elastic deformation. Initially, the rubber compound behaves as a solid and resists deformation due to its elastic properties. As the shear stress increases, the compound starts … Continued

Sulfur and ph of carbon black in rubber compounds

Sulfur level and pH are important factors in the production of rubber compounds that contain carbon black. Carbon black is commonly used as a reinforcing filler in rubber compounds to improve their strength, stiffness, and abrasion resistance. Here’s how sulfur level and pH affect carbon black in rubber compounds: Sulfur level: The level of sulfur … Continued

Silane coupling agents

SI69 is a type of silane coupling agent that is commonly used in rubber compounds to improve their properties. Silica-filled rubber compounds are widely used in tire manufacturing, as they offer improved fuel efficiency, better wet grip, and reduced rolling resistance compared to traditional carbon black-filled compounds. When SI69 is added to a silica-filled rubber … Continued

OVERALL EQUIPMENT EFFECTIVENESS

Overall equipment effectiveness (OEE) is a performance metric that is commonly used in manufacturing and industrial settings to measure the efficiency of equipment. OEE measures the equipment’s effectiveness in terms of its availability, performance, and quality. The formula for calculating OEE is: OEE = Availability x Performance x Quality Where: Availability: The percentage of time … Continued

8 P’s of Lean

The 8 P’s of Lean refer to a framework used in lean manufacturing and business processes. They are: Purpose: A clear and concise statement of the objective of the process or activity. This helps to keep the focus on the goal and align all efforts towards achieving it. Process: A well-defined and structured approach to … Continued
