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.

Injection Molds for Various Thermoplastic Resins

 

Thermoplastic resin is the most common type of polymer used in the injection molding process. There are several different types of thermoplastic resins with varying properties, including shrink rate, resistance to high temperatures, resistance to corrosives, elasticity, adhesion, finish such as polished or matte, and fatigue strength.  

These are all very important considerations when designing an injection mold to manufacture parts molded from thermoplastic resins.  Shrink rate is extremely important, as the cavities in the tool would have to be adjusted for such shrink rate.  Cooling rate is also very important to consider during mold design, and is important for ejection.  The part must be completely set and solid prior to ejecting from the mold.

When designing a tool for injection molding with thermoplastic resin, mold flow analysis may be helpful or even necessary to identify any critical areas in the part design.  Mold flow analysis is a computer aided simulation that shows clearly how the material will flow, based on its own individual properties.

By predicting these critical areas ahead of time, the mold designer can adjust for tight tolerances, problem areas for material flow and fill, and to identify the optimum location for gating.  This is a valuable tool when designing precision molds for critical components, and is a useful tool to avoid costly mistakes and improving lead times.

While mold flow analysis can be a valuable tool, the best knowledge of how particular thermoplastic resins flow comes from experience.  Experienced mold designers are well aware of the specific properties of different polymers, using that knowledge to design the tool properly to mold the part to print.

What is Precision Injection Mold Making?

mgmold

Not all injection mold making is precision injection mold making.  Some examples of products that do not require such precise molding would be toys, bottles, combs and other miscellaneous items that do not necessitate a stringent level of quality.  Products made for industries such as Automotive, Aerospace, and Government / Military and Ordnance will demand the expertise of a precision mold maker.

Experience is Necessary

Precision mold makers must be familiar with meeting tight geometric tolerances, as narrow as +/- .001 of an inch.  Experience with the plastic injection molding process, especially tooling, is required for a molder to accurately meet rigid tolerances.  Some parts for the above mentioned industries are quite complex with several gates and cam action occurring in the mold.  Expertise in complex molds is required for precision work.

Technology

Automation is also a necessity to consistently meet meticulous requirements.  A process monitoring system is a software program with sensors attached to each press that monitors things such as the pressure, temperature, cycle time and shots molded.  The sensors work with a computer program to keep track of all molding information for each press, contains a scheduling module, and stores all pertinent information for each production run.  While molding, If any of the critical settings should falter out of an acceptable level, an alert system would sound and let the process technicians know to check the process and make any alterations before molding defective parts.

Material Management

With so many different engineering resins to choose from, there are a number of different molding conditions that apply to specific situations.  Some materials are molded with water lines cooling the process, and yet other materials require a hot temperature that can only be reached with a hot oil. The hydrolysis (water content) of the material will also affect the molding process.  Some projects require a complete drying of the material to achieve optimal results.

Controlled Environment

The molding environment must be controlled to maintain a consistent process. Temperature affects the molding process in several different ways, and the experienced precision injection molder knows how to maintain consistency with maintaining a controlled environment.

Quality Practices

Precision Injection Mold Making for demanding industries requires the company to follow necessary quality procedures.  Michiana Global Mold is registered to ISO9001:2015, providing assurance that your mold will meet required tolerances.  These quality standards dictate how a mold maker performs all day to day operations, not just the mold making process, and are enforced from top management down, practicing a stringent quality policy throughout the entire organization.

By practicing quality control procedures such as Statistical Process Control (SPC), and Advanced Product Quality Planning (APQP), Michiana Global Mold  provides customers with required data to support required specifications.

Value Stream Mapping (VSM) is performed for optimal efficiency and cost reduction initiatives are shared with customers.
