Injection Mold Design for Engineering Resins

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.

Precision Injection Molds Meet Customer Specifications

Injection mold designs today must meet tough customer specifications, calling for critical fill areas with precision mold designs.   Careful planning must be taken when designing complex molds for critical applications, ensuring consistent packing and filling to tight geometric tolerances.  A qualified mold design engineer has several important considerations when beginning a complex injection mold construction, beginning with a carefully planned mold design.

CAD/CAM for Mold Design

Computer aided design and manufacturing is a valuable tool for injection mold designers, providing accurate 2D drawings and designs to meet customer specifications.  The use of CAD/CAM is beneficial when constructing molds for any industry, especially when designing and constructing injection molds for the automotive industry.  

Unigraphics and SolidWorks are two of the most technologically advanced software design programs used to satisfy the complex demands of the automotive industry.   Mold Flow Analysis is another valuable tool to identify potentially challenging fill areas, especially when using a specialty resin that may be unfamiliar to the molder.

These computer simulations are part of a thorough Advanced Product Quality Planning (APQP) set of procedures which ensure a successful mold launch.  APQP procedures are critical to the planning phase as following a detailed set of procedures identifies any issues with resin, geometric challenges such as a thin wall or critical dimensions that must remain within +/-.001” for proper functionality.  

Michiana Global Mold utilizes CAD/CAM software as part of our thorough APQP procedures, to ensure a quality constructed mold for even the most complex of mold designs.  As an ISO registered injection mold making shop, we are experienced with providing a quality mold made to customer specifications, on time and within budget.  We work closely with our customers to develop a successful mold launch to meet even the strictest of specifications.

A Mold Maker’s dilemma: EDM or Mill?

Quick response and flexibility are required of tool and die makers today.  Mold makers must continually strive to reduce production time while still ensuring a high level of quality, and all while providing cost reductions.  With tight margins and high demand for quick turn-around, tool and die makers may be searching for the best manufacturing method to remain competitive.  

 

Using an EDM machine (electrical discharge machine) along with a high-speed milling machine may provide assistance with on-time delivery.   Certain manufacturing needs in a tool and die shop may require differing manufacturing methods.  The design engineer should be aware of all available manufacturing technologies.  

 

Mold Manufacturing Products Require Differing Technologies

 

Injection molds and diecast molds, forging dies, and deep drawing dies are the three main products of tool and die making.  Deep drawing dies mean that the metal blank is drawn into a forming die with a punch.  The drawing is considered to be deep drawing when the depth of the drawn part is greater than the part diameter.   They all possess their own constraints regarding applicable technologies for mold production.

 

Deep drawing dies have flat structures and materials that are best manufactured with milling.  When producing forging dies, EDM is widely used due to the strength of materials used in production.   Complete machining with milling is possible, however, with low depth and large concave radii.   

 

Milling diecast and injection molds is challenging due to ribs or webs, and small radii.  Developing the combination of EDM and milling is necessary for economical mold production meeting tight tolerances.  Utilizing the benefits of all production methods gives designers and mold manufactures options in mold manufacturing.  

 

Other considerations in deciding between EDM or HSM are high speed milling, the geometric constraints, and surface quality or subsurface damage of a tool.   Of the utmost importance is the effect on the surface from either EDM or HSM, as related to the part specifications.  Some parts may require a surface conducive to adhesion from certain coatings or lacquers, and the finish of the tool plays an important role in the surface finish of the molded part.  

 

Employing skilled design engineers and journeyman mold makers, we have the experience to utilize the latest technology with a full line up of modern EDM and high-speed milling centers.  This gives the most benefit to our customers in providing the most efficient, and cost effect mold manufacturing, with high quality tools and on time delivery.
