Advantages of an ISO Registered Mold Making Shop

There are many advantages gained with using an ISO Registered mold making facility for construction of your injection molds.  Plastic injection mold making shops are expected to meet just in time delivery deadlines with tight tolerances within specifications.  Today’s injection mold making industry leaves no room for error as mold making shops must utilize modern technology with experience and in-depth knowledge of the injection mold making process in order to satisfy the stringent requirements of OEMs today.

The Internationally recognized quality standards of ISO9001, ISO/TS16949 and AS9100 set common parameters for various industries around the globe to measure their performance in either their service or product with a uniform set of standards.  Any supplier to the Automotive industry should be registered to ISO standards. In some cases, proving compliance may be adequate for a 3rd tier supplier, although most 1st and 2nd tier suppliers must be registered to either ISO or ISO/TS.

This gives Automotive suppliers around the globe the same set of standards to adhere to, making the job of the Automotive Quality Engineer from one of the top Automakers a little easier to compare vendors.  In order to stay in the preferred vendor status, an injection molding shop and even the injection mold making shops must not only be registered to ISO standards, they had better be practicing their Quality Policy and performing continual improvement projects in order to stay competitive.  

Mold making facilities meticulously follow detailed checklists ensuring that all issues are recognized and address prior to cutting steel.  ISO Registered mold making shops that follow Advanced Product Quality Planning (APQP) reveal any critical issues with mold construction such as critical fill areas to tight geometric areas, the need for CAM action, lifters or specialty ejection systems.  Identifying these critical issues ahead of time is crucial to fulfilling a tight deadline with a quality mold.  

Michiana Global Mold is a global supplier of high quality injection molds, registered to ISO  9001:2015 and implementing our Quality Policy throughout the organization.  We have been satisfying the stringent requirements of the Automotive industry with high-quality, custom, precision injection molds for over 52 years.  Contact us today to see how we can assist you with your injection mold building needs.

Mold Design and Automated Injection Molding

When an injection mold designer begins a development of the mold design, they must be aware of the environment in which the mold will run.  This includes the size and type of press the mold will run in, the material used for molding, and any auxiliary equipment used for automation as the location of tie bars and cooling lines must not interfere with setting and running the mold.

 

Vacuum Conveying System

 

A vacuum conveying system is an automated way to get the material into the press, with the right suction and force.  Vacuum conveying systems suck the material while still in pellet from the gaylord or drum into the hopper of the press, providing a steady flow of material for continuous production.   Vacuum conveying systems pull in a steady flow of material, and control the amount of material in flow to the press, and are also helpful with controlling the moisture content in the material.  

 

Sprue Pickers Aid Automation

 

Sprue pickers are robotic arms that reach into the press and grab the runner when the mold ejects, instantly separating from it the parts which can then fall into a bucket or onto a conveyor belt.  Some robotic sprue pickers reach in and pick up the runner then drop it either into a separate bin, or directly into a grinder where it can be ground up and reused as regrind material.  

 

Process Monitoring

 

Injection molders use process monitoring systems to constantly monitor the press settings such as temperature and pressure, alerting an operator if the job begins to run out of specification.  Some monitoring systems also provide material resource planning functions, tracking job due dates and material inventory for scheduling of jobs.  

 

All of the additional auxiliary equipment must function properly and work in conjunction with the mold when it opens and closes and operates on the tie bar.

Mold Design Considerations for Thermoplastic Resins

The most common type of polymer used in injection molding is thermoplastic resins.  There are many different types of resins with various properties to meet part specifications for functionality.  When designing injection molds, the engineer must take into consideration all properties of the resin specified for the produce including adhesion, elasticity, resistance to high temperatures, shrink rate, resistance to corrosives, and desired finish whether matte or polished.

 

The cooling and shrink rate are of the utmost importance, as some parts with a high shrink rate will need the cavity designed accordingly so the finished product will cool and shrink within specifications.  Cooling rate is also important for ejection, as the resin must completely solidify prior to mold ejection.

When an injection molded part has a critical functionality, mold flow analysis may be helpful in determining resin flow into tight geometric areas.  Mold flow analysis clearly shows with computer aided simulation how the resin will flow as determined from its properties.  Predicting how thermoplastic resin will flow in the mold and cavities prior to cutting steel can be a valuable tool in avoiding costly mistakes.  Conducting the proper advanced quality planning with mold flow analysis can greatly improve lead times.  

Most journeyman mold makers will already possess the knowledge of hos particular resins flow just from experience.  A skilled design engineer with experience in manufacturing molds will have the knowledge to design the tool to produce a part to print specifications, with the chosen resin properties playing a huge role in tool design.

At Michiana Global Mold, we have been providing high quality precision molds for over 60 years, possessing more than 500 years of combined experience.  Our staff of highly skilled design engineers and journeymen mold makers are the best in the business with vast experience in various thermoplastic resins.

Press Considerations for Injection Mold Design

 

 

When constructing plastic or rubber injection molds, in addition to the part design the molding environment that the tool will run in is of the utmost importance.  A mold designer must be aware of the injection molding process that the tool is designed for, the press it will run in including the clamping system and whether or not it is a vertical or horizontal clamping press.

 

Each injection molding press will have a particular clamping pressure that is either delivered in an electric or hydraulic system.  Some molders prefer to use all hydraulic presses, while some have a mix of hydraulic and electric, while other molders use only electric machines.  There are some benefits to both, but the mold designer must be well aware of the power and pressure utilized in the press of choice prior to designing and constructing the injection molds.

 

A mold designer, and mold builder will need to know the tonnage of the press, the clamping orientation and clamping pressure whether it is electric or hydraulic, and they will also need to know the barrel capacity of the press.  This will determine how much material will be able to flow into the mold, and based on cycle times and cavitation, will determine whether or not the tool is designed to meet projected production volume requirements.

 

Each injection molding press will also have a certain type of mounting system to secure the mold in the press.  A toe-clamping system is most common, although a skilled mold designer can adapt the tool to fit even a custom designed mounting system.  The platen must be large enough to hold the mold but it must also allow enough room to pass through the tie-bars when loading or unloading the mold.  The tie bars hold the mounting platens in place which securely hold the mold in the press, and also contain the ejection system allowing opening and closing of the mold.
