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.

High Quality Precision Production Injection Molds

Production injection molds are used to mass produce plastic injection molded parts.  Injection molding is the producing of specially designed plastic parts by injecting with pressure and clamp force, plastic in a molten state into cavities carved out in a steel mold where the plastic will harden and set to the shape of the mold, thus producing the part.  

 

Injection mold makers sometimes produce a prototype tool to test out a part design and function prior to manufacturing full production requirements.  Production molds are used for long term production requirements.  A prototype tool is used only for short runs to produce sample parts for testing and will not support full production.

 

With proper planning and mold design, a custom mold maker will design and manufacture a production mold that will meet all product specifications and geometric dimensions.  Some of these dimensions must be met with the tightest of tolerances as close as .001”, or about the width of a human hair.  Carving out the cavities of a steel mold to produce a plastic part within these tight tolerances is no easy task, especially when taking into consideration the properties of the thermoplastic resin including cooling and shrink rate, which can have a great effect on the final dimensions of the part after solidifying.  

 

If a change is required of a production mold, skilled mold makers can perform what is called an “engineering change” to alter a dimension or tolerance within a part.  If the change is feasible just by altering some dimensions in the steel, mold makers can simply adjust some dimensions in the current tool and avoid the need of constructing a new mold altogether.  

 

Skilled and experienced mold makers will utilize advanced quality product planning procedures to ensure that the constructed production mold will produce parts to spec the first time, planning ahead for critical fill areas and ensuring parts to print.
