Thermoplastic engineering resins are the most common type of plastic resins used in the injection molding process. With many different types of plastic resins each with their own unique properties, it takes great care and consideration to properly design and construct a mold for use with thermoplastic resins. These highly useful polymer resins have varying properties of elasticity, resistance to temperature, corrosives, shrinkage and right down to the exterior finish such as a matte or a glossy finish.
Shrink rate is a very important property of thermoplastic engineering resins used in injection molding, as the cavities must be carved out to accommodate to this shrink rate. If shrink rate is not accounted for properly, a part may shrink too much after cooling and deviate from customer requirements. Knowing the cooling and shrink rate of the polymer resin used for any molding process is of the utmost important to the journeymen mold makers constructing the tool. Cooling rate is also important for the part to become completely solidified prior to ejection. Cooling rate must be configured into the injection molding cycle time, to ensure proper cooling and ejection without damaging the part. Each polymer resin will have a MSD sheet, Material Safety Data sheet along with material specifications clearly defined in each numbered lot of all thermoplastic resins. If working with a new material, a mold designer may prefer to use Mold Flow Analysis, for a computer simulated demonstration of how the plastic material will melt, flow and fill. Predicting the flow of thermoplastic resins prior to cutting steel is vital for accurate geometrical tolerances in the final product. Even with a material spec sheet which is necessary, nothing helps a skilled mold designer more than experience. Skilled mold design engineers are very familiar with the various properties of engineering resins allowing for precise mold construction with even the most specialty of molding resins.

Experience There are at least three very important factors when looking for a qualified mold builder: Experience, Technology, and Resources. Experience is crucial when designing and building complicated, precision injection molds. An experienced mold designer and mold builder will have encountered many situations that enhance even the most skilled and experienced mold designer. As in any other situation, one continues to draw form their experiences. Even with technology and resources, nothing can provide you with the knowledge and ability to recognize solutions like experience. At Michiana Global Mold, we have been supplying the automotive industry with precision complex tool designs and injection molds for over 52 years! We have a combined experience of over 600 years with our skilled designing engineers and journeyman mold makers. Technology Technology is a very important factor in any design, construction or manufacturing operation and is no different for injection mold making. Gone are the days where the journeyman mold maker will carve out the steel cavities by hand, meeting tight tolerances within a thousandth of an inch, (the width of a human hair)! Journeyman mold makers possess a great mathematical mind that is necessary to build precision tools, but the technology is ever changing, aiding and assisting with complex tool designs. Michiana Global Mold has an impressive line-up of technologically advanced machinery and equipment, including several EDM and CNC machines, Milling Centers, Wire EDM, Saw, Drilling equipment, Grinders, and many more new and impressive machines giving us the capability meet your tight deadlines with precision tools delivered in spec, and on time. Resources Having enough manpower and equipment is necessary to meet tight deadlines on multi-tool projects. A large capacity tool shop with various milling centers and technologically advanced software programs is vital to timely injection mold construction. Global resources are also important in the mold making industry, as many OEM’s and manufacturers want the cost effectiveness of offshore molds. It can be tricky to find a mold builder with offshore resources, that can still manage your project with clear communication in a timely manner. Michiana Global Mold has a large capacity tool shop in the heart of the mid-west in the United States, and has a partnership with Modular Mold in China, offering our customers the best of both situations. If you need globally sourced injection molds, Michiana Global Mold has the solution for you, providing offshore molds with domestic pricing. Our US location is also fully staffed with expert design engineers, and journeyman mold makers, giving you decades of experience. This experience, combined with our technologically advanced equipment and vast resources allows us to provide the most cost effective solution to your mold building requirements. Contact Michiana Global Mold today to learn how we can assist you with your ever changing, and demanding supply chain requirements. We have the experience, technology, and the resources to give you the best mold building solution available, whether from our domestic or offshore location. |
