What is the difference between hot runner vs cold runner systems? With the increasing cost of steel and raw materials, supply chain professionals are often looking for options to reduce part prices, cycle times, and material waste. Cold runner systems may be a cost saving solution compared to hot runner systems for the right application. […]

Introduction Rubber molding processes, such as extrusions, compression molding, or injection molding, take liquid raw rubber into a mold where the rubber is then cured into the mold shape by heat and pressure. As such, the mold cavity is cut to represent the desired geometry of the molded rubber product. Products such as o-rings, seals, […]

What are the factors that affect the tolerances of molded rubber products? Many factors in the manufacturing process can affect the tolerances of the molded rubber product. In general, the consistency of dimensions will be contingent on the rubber material, mold tool, product design, and conditions of measurement. Shrinkage All rubber go through some degree […]

Natural Rubber (NR) is usually the material of choice in vibration and noise damping applications due to their excellence in strength and resilience. However, technological strides have been leading to ever smaller equipment and compartments, therefore decreasing the available airflow for components. This has led to rising temperatures under the hood, exposing the limited stability […]

Definitions Resilience is the percent of energy required for a deformed pieces of rubber to rebound back to its original shape after a deformation. Hysteresis is the percent of energy loss per each deformation. Hysteresis results from friction happening inside the rubber which creates heat build-up. The heat build-up in the rubber is measured as […]

Custom rubber molding is the best choice for medical devices for a number of reasons. Medical device developers can define the most appropriate flexibility, fit, appearance, chemical resistance, and other features for their product. Custom rubber molding for medical devices would be able to give the highest quality product that can perform better, be more […]

Rubber molding is used to make almost endless types of items such as shoes, football gear, car parts, etc. It is eye-opening how nearly everything we use contains some type of rubber component. Natural rubber can be harvested then processed into usable and versatile rubber; however, natural rubber contains proteins which may cause sensitivity in […]

Hoses, tubes, and pipes can be vulnerable to damage by repeated flexing or friction, exposure to the environment, and contamination by foreign materials. Damage to hoses, tubes, and pipes can certainly lead to safety issues as well. Aside from abrasions, grommets are also used in applications where hoses, wiring, and cables need insulation, vibration protection, […]

Perhaps you’ve heard high quality product should have “tight tolerance,” but do you really know what level of tolerance is suitable for your product? Depending on the end use of the product, tight tolerances may or may not be necessary for the product. Most consumer type products do not require more than the standard tolerance, […]

The modern rubber molding machine was actually adopted from the plastic molding process known as injection molding. Injection molding is a manufacturing process to make molded products by injecting a heated raw material into a mold cavity in which it is cooled and hardened into the mold shape. This system of manufacturing is still being […]
