A Process Control Plan (PCP) is a systematic and detailed document used in manufacturing and various industries to ensure that production processes are consistent, controlled, and capable of producing products that meet specific quality standards. The primary purpose of a Process Control Plan is to minimize process variation, identify potential issues, and outline corrective actions to maintain product quality and efficiency. A typical Process Control Plan includes the following key components: 1. Process Steps: A clear and well-defined description of each step in the production process, star ..read more

In lean manufacturing, a control plan is a key tool used to ensure consistent quality and process control throughout the production cycle. It outlines the specific actions and measurements required to maintain quality standards, prevent defects, and minimize variation. The control plan is typically developed as part of the overall quality management system in a lean manufacturing environment. Here are the key components typically included in a control plan: Process Steps: The control plan begins by listing all the process steps involved in manufacturing the product. Each step is described i ..read more

In-situ-situ and ex-situ
Goodyear Rubber

“In-situ mix” and “ex-situ mix” are terms used to describe the process of mixing silicone rubber compounds. In-situ mix refers to the process of mixing the silicone rubber compound directly at the manufacturing site or application location. This involves combining the base silicone material with various additives and catalysts to form a uniform mixture, which is then applied or molded in the desired shape. The in-situ mix approach is often used for applications where a precise, custom mix is required, or where the material needs to be applied in hard-to-reach areas. On the other hand, ex-situ ..read more

Steam Resistant Silicone – long chain functional polymer surface treatments
Goodyear Rubber
by Flynn
1y ago
Examples of longer chained functional polymer surface treatments for fumed silica include: Silane coupling agents: Silane coupling agents are widely used to modify the surface of fumed silica particles. These agents typically have a longer chain length (e.g., C18) and contain functional groups such as amino, epoxy, or methacrylate. The silane coupling agent reacts with the surface of the fumed silica particle to form a covalent bond, creating a stable interface between the particle and the surrounding matrix. This can improve the dispersion of the fumed silica in the matrix and enhance the mec ..read more

Plasticity: Free Volume, Gel, Lubricity Theories
Goodyear Rubber
by Flynn
1y ago
The lubricity theory, free volume theory and the gel theory are three theories that explain the plasticization of rubber compounds. The lubricity theory suggests that plasticizers improve the lubrication between the polymer chains in the rubber compound, which allows for easier movement and greater flexibility. According to this theory, the plasticizer molecules are inserted between the polymer chains and act as a lubricant, reducing the friction between the chains and allowing them to slide past one another more easily. This results in a softer and more pliable material. The Free Gel theory ..read more

Plasticization
Goodyear Rubber

What is Plasticization? Plasticization of a rubber compound refers to the process of adding plasticizers to the rubber to improve its flexibility, workability, and other properties. A plasticizer is a chemical compound that is added to a material to make it more pliable and easier to shape. In the case of rubber, plasticizers are added to improve its processing characteristics such as reducing the viscosity of the rubber compound, making it easier to mix, extrude, or mold. This can also improve the physical properties of the rubber, such as its elongation, tensile strength, and tear resistanc ..read more

Value Stream Mapping (VSM) is a lean management tool used to analyze and visualize the flow of materials, information, and activities required to bring a product or service to the customer. The objective of value stream mapping is to identify waste and opportunities for improvement within the value stream. In value stream mapping, the value stream is depicted using a visual representation that shows the flow of material and information from the beginning of the process to the end. This visual representation helps teams to identify and understand how value is created within the process, as we ..read more

Muda – Lost Creativity

“Muda” is a Japanese term that refers to any activity that does not add value to the product or service being produced. In lean manufacturing, eliminating muda is a key strategy for improving productivity and efficiency. One type of muda that can have a negative impact on creativity in the workplace is “lost creativity.” This occurs when employees are not given the time or resources to explore new ideas, experiment with new processes, or innovate in their work. Lost creativity can arise for a variety of reasons. For example, a company may be so focused on meeting short-term production goals ..read more

A C-shaped manufacturing cell is a type of manufacturing layout that is designed to optimize efficiency and productivity in a manufacturing process. It is named for its C-shaped configuration, which allows for a streamlined flow of materials and products through the production process. In a C-shaped manufacturing cell, the production equipment is arranged in a semicircle or a U-shape, with the workers located in the center of the cell. This layout allows for easy access to the equipment and promotes communication and collaboration between workers. It also minimizes the amount of material hand ..read more
