Batching system and controls for rubber
A global manufacturer commissioned the company to create a customized batching and mixing control system to improve rubber compounding batch integrity and increase overall production through automation. The customer needed to update its existing aged batching system. The new system would need to add more capability and automate the handling of bulk dry and liquid materials, scales and manual weighed materials that are introduced into the internal mixers. A control system was designed to incorporate four main processes, including the hand add weighing process, the main batching process, the mixing process and the batch-off process. Each manual add station consists of a control panel with a PanelView Plus and an Ethernet weight instrument. The system allows the hand add stations to batch ahead and pre-stage totes for the main batching process. Hand add HMI screens prompt the operator to place a container on the scale and to use an RFID scanner to scan container tags. The system then displays which ingredient to weigh into the container in a pre-determined sequence to complete the batch. The system utilizes bins with limit switches on the lids in order to confirm that the correct ingredient has been selected; and after confirming, the operator is prompted to weigh the specified amount of the required ingredient. The operator continues the entire batch sequence, weighing each ingredient in this manner. As the operator completes each tote, it is placed on the hand add conveyor. The main batching process is controlled from the main control panel using an integrated dual screen display and industrial computer running Rockwell Software FactoryTalk View to provide a wide touch screen interface and a dedicated mixer display monitor.

In-line gear pump straining offers advantages
Custom rubber mixers use many technologies and processes to help prevent undispersed materials and foreign particle contamination. One such process is in-line gear pump straining, which improves final product quality by filtering contaminants directly following the mixing process. Gear pumps use two counter-rotating gears to push rubber compound through a temperature-controlled chamber. The material is then strained through a fine-mesh screen pack before exiting through a die head and formed back into strips. The company utilizes in-line gear pump units on each of its three mixing lines that are fed directly from the finishing mill. As material is fed through the gear pump, the temperature controlled chamber ensures a low material temperature increase, despite high pressure within the gear pump. This process purifies the rubber without changing or damaging the compound. This is said to make in-line gear pump straining ideal for purifying both masterbatch and compounds with cure. In-line gear pump straining creates a unique advantage for material processing, according to the manufacturer. For the mixer, it is said to add flexibility in raw material selection and improve overall compound quality. For the part fabricator, it is said to reduce issues during processing (such as extrusion, molding or calendering), and to provide a predictable and stable continuous output of final parts with fewer overall defects. This reduces scrap, and in turn lowers the overall cost of production, according to the company. The firm is a state-of-the-art custom polymer mixing company that develops and produces a wide variety of technical grade rubber products using advanced mixing and controlling systems.

Dust collection testing
Dust collection testing A global manufacturer of dust, mist and fume collection equipment has doubled the size of its testing laboratory to include a climate-controlled facility with a full-size dust collection test rig. The equipment is dedicated to testing in accordance with ANSI/ASHRAE Standard 199-2016, Method of Testing the Performance of Industrial Pulse Cleaned Dust Collectors. Unlike other air filter standards that focus on HVAC systems, the Standard 199-2016 test process analyzes how well filters actually clean and how dust collectors perform as a whole. It is said to be the first standard to provide a methodology for comparing performance results based on true operating conditions. Using a cartridge dust collector with four high efficiency filters, the unit feeds dust into the collector under specified conditions, measuring pressure drop and downstream emissions. The company will use the test rig for both internal product quality testing and to help customers simulate real-world conditions to evaluate the compliance and effectiveness of various filters.

Dry ice cleaning solutions for the tire industry
Dry ice cleaning solutions for the tire industry In tire production, major challenges need to be controlled by tire manufacturing companies, including the technical development of materials, mixture of compounds and the production process, according to the company. A critical part of the production process is the maintenance and cleaning of molds. Clean molds are said to offer flexibility and have direct impact on the production capacity and cost. Safety, noise and secondary waste are also key reasons why tire manufacturers need to review and control the mold cleaning process. The current trend in tire mold cleaning is said to be to clean in place, automatically and non-abrasively. The tire manufacturer must control the maintenance process. Solutions for tire manufacturing companies are offered to control this critical cleaning process with MicroParticles, said to be the finest dry ice particles that offer the fastest and most efficient clean. The company's patented MicroParticle technology combined with its SureFlow system is said to deliver on the needs of the tire mold cleaning industry by addressing the material and complexity of the mold, the valves and vents, the integration of the system in the existing environment, the press downtime, safety, noise and the environmentally responsible cleaning project. Safety is also said to be one key reason tire manufacturers need to review the actual process and why the company's system is said to be preferred over alternatives. A faster clean with less noise is only one of the arguments in favor of dry ice cleaning. Tire manufacturing companies need to ensure that the safest process with minimum downtime is achieved in their facility, according to the company.
