The success of your single or multi-component material highly depends on the solution for packaging, metering, mixing and dispensing. The success of a single or multi-component material within its markets depends, to a large degree, on the system chosen for packaging, metering, mixing and dispensing. The vast, reliable, robust MIXPAC product range from Sulzer provides a multitude of benefits for its user. Aside from being highly reliable, repeat a ble, and simple to use the MIXPAC systems offer clean and safe operation. In choosing the optimal system for the material many factors need to be considered, such as: the cartridge mate rial, piston technology, plunger, closure cap, the mixer, and dispenser. These factors, when properly evaluated, will inevit ably avoid problems during the application of the material. Our expert Technical Services team, headquartered in Switzerland, has unlimited access to a well-equipped state of the art laboratory and is constantly working to improve our products and support services. This well experienced group, armed with in house computational fluid analysis (CFD) capabilities and a multitude of methods for physical analysis, is building a library of technical tools. Sulzer Mixpac is the only solutions provider in our markets with such a large portfolio of methods intended to minimize expensive, time consuming, trial and error physical tests invariably reducing the time to market for our customers. Within the following pages we offer you more detailed description of some of our services we extend to you. If there are open questions please do not hesitate to call your local contact at Sulzer Mixpac. Our experts are also here for you. Because of this know-how, we can call ourselves the worldwide technology leaders in providing solutions to package, meter, mix and dispense single and multicomponent materials which serve the dental and healthcare as well as industrial, construction and protective coating markets.
Packaging Compatibility Test The compatibility test is one of the first steps necessary for determining a suitable cartridge system for packaging your materials. The aggressive nature of these materials can have adverse effects on particular types of plastics and a thorough investigation should always be conducted. We can conduct accelerated aging tests in a climate chamber, infrared spectroscopy and/or gas chromatography in-house to prove material compatibility. CT Scanning and X-Ray Any air trapped in your full cartridge can hinder the performance of your mixing system. Our Technical Services group offers you the opportunity to test whether the filled cartridge is reliable. By means of CT scanning and X-rays, we investigate the system and are able to find and determine the amount of trapped air. This provides you with a level of security and indicates whether or not you need to improve the filling process. Durability Test The mechanical stability of cartridges and syringes that contain your materials is influenced by various factors. We examine the interplay of these two components in our laboratory, in terms of shelf life, long-term compatibility, leak tightness, and resistance. Various storage conditions are tested, such as humidity, variation in temperature, changes in air pressure, and storage duration. As a result, you will be confident about your systems resistance and reliability as well as achieving optimum storage conditions to ensure a good material shelf life.
Metering Flow Rate A defined mixing system requires the maximum output force, which we determine by computer simulation and practical tests. With this information, we can determine which mixer produces the best flow rate as well as minimal material waste. Dispenser Force Dispensers play an important role for the metering accuracy of your adhesive. We are able to evaluate the viability of a dispenser to be used with our cartridge systems. We measure the output force in detail using its performance curves, examine the integrity of the drive system, and quantify overall function, handling, and the risk of problems occurring. This way, we make sure you operate with dispensers which are tested and proven to work. Mixing Quality In order to examine mixing quality, there are two methods we apply in our laboratory. First, we reproduce ambient conditions to analyze air inclusions, mixing performance, cure times, and delamination, and we give recommendations based on these results. Second, we offer simulations (CFD) to calculate efficiency and functional reliability which help to keep the number of practical tests to a minimum. Spray Test To determine whether your material can be used with our cartridges, we offer a spray test in our laboratory. First, we check for mixing quality and flow rate by dispensing your product without air pressure. As a second step, we spray your material on test surfaces to examine surface finish, coating thickness and inhomogeneity. With this test, we figure out whether you are working with the right system and give recommendations and information about the reliability of your mixing process.
Mixing Viscosity Our Technical Services group has the expertise and equipment to analyze the shear rate of your materials used with our mixing system. We examine the viscosity of your components in conjunction with various mixing geometries dependent on shear rate, temperature, and time. As a result, we determine components which suit your material, and find opportunities to optimize the entire system. Mixing Quality In order to examine mixing quality, there are two methods we apply in our laboratory. First, we reproduce ambient conditions to analyze air inclusions, mixing performance, cure times, and delamination, and we give recommendations based on these results. Second, we offer simulations (CFD) to calculate efficiency and functional reliability which help to keep the number of practical tests to a minimum. Flow Rate It is advantageous to select the smallest mixer possible that is capable of delivering the necessary mixing quality and flow rate to fulfill the application requirements. Through the use of computer simulation and practical tests, we are able to make sure that the maximum force of the dispensing tool is used to guarantee minimal waste and high performance.

Coating Test To determine whether your material can be applied with our spray and brush equipment, we offer a coating test in our laboratory. First, we check for mixing quality and flow rate by dispensing your product. Then we spray and/or brush your material on test substrates to examine surface finish, coating thickness, and homogeneity. With this test, we can determine whether you are working with the right system and give recommendations and information about the reliability of your mixing process. System Functionality It is essential that all components of a mixing system operate in accordance with each other. The wrong selection or frequent substitution of a single part can lead to insufficient performance and ultimately to dissatisfaction with the end product. We check the functionality of your mixing system, analyze the risks and give guidance. In the end, you receive a reliable product with a high level of performance.
