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.

If your project requires precision injection mold making, consider partnering with Michiana Global Mold to add value to your supply chain.

Thermoplastic Molding

mgmold

Injection Molding with Thermoplastic Resins

Thermoplastic molding refers to the process of injection molding thermoplastic resins.  Thermoplastics is a type of polymer that melts and becomes pliable when reaching a certain temperature, allowing it to be molded into various forms.  This type of polymer can also be ground up and reused after hardening, as opposed to thermoset polymers, which cannot be melted and used again.  The third type of polymer is elastomer, which can also be thermoplastic, in which case this type of material is referred to as thermoplastic elastomers.  Thermoplastic resins are the most common type of material used in the injection molding process.

The Molding Process

The equipment required for thermoplastic molding is the same: a press, a steel mold, and plastic resin.  The resin is poured into a hopper on top of the press, and is then drawn into the press where it is heated in a barrel and injected into a steel mold where cavities carved out by journeyman mold makers form the molten plastic into the shape desired.  The steel mold is usually equipped with water lines running through it to cool the parts before the mold opens and parts are ejected.  Each time the mold opens, molds parts, and ejects them is called a cycle.  The typical injection molding cycle is measured in seconds.  Decreasing the cycle time can lead to improvements in efficiency and the bottom line, as long as it does not jeopardize the functionality of the part.

The Mold

The mold is the steel frame that contains the carved out cavities to actually form the part.  Every injection molding job requires a steel mold to form the molten material into a usable functional part.  There are different types of molds for different applications, but the most common is a class A hardened steel mold, capable of producing hundreds of thousands or millions of parts without wearing out. 

For the typical thermoplastic molding process, a steel mold will run in a horizontal molding press, meaning the mold will open and close on a horizontal plane.  In this case, when the mold opens and ejects the parts, the runner is also ejected.  The runner is the residual molten plastic that hardened in the channel getting the plastic to the cavity in the mold.  This is true of a cold runner mold, which is the most common injection mold.  A hot runner mold, in contrast, injects plastic directly into the cavity from a nozzle, and therefore has no runner.  A hot runner mold can assist with automation, but it is more costly than the more common cold runner mold. 

Equipment Required for Automation

While the necessary equipment is the same, a molder can invest in auxiliary equipment to automate the process and run parts without an operator, and sometimes even in a ‘lights out’ environment.  A vacuum conveying system sucks the plastic resin while in pellet form from a drum or gaylord into the hopper on the press.  As long as enough resin material is in the drum the conveying system will automatically supply a steady stream of thermoplastic resin into the press.  There are ways to regulate the amount of pellets drawn into the hopper at a time.  Some molders even have ways to measure the moisture content of material, and dry it accordingly before it enters the press.  Some molders use a moisture analyzer when required. 

Sprue Pickers Assist with Automation

When a cold runner mold is used in a horizontal press, the runner will eject with the parts and either drop to a bin below, or be grabbed by a robotic arm called a sprue picker.  A sprue is another term for a runner.  Sprue pickers assist in the automation process because it separates the parts from the runners, allowing the parts to collect in a tub by themselves and not need to be sorted or separated from the runners. 

Process Monitoring Adds Consistency and Reliability

A Process Monitoring System should be utilized for automated molding as it will monitor, as the name implies, the process as it is happening.  If something began to run out of spec, such as temperature or pressure, an alarm would sound to alert a technician.  These monitoring systems also function as material resource planning software, allowing the user to input specific job information and schedule production. 

These are some of the ways a molder can automate the injection molding process. If precision parts manufacturing is required, automation could assist to provide to a consistent and reliable process.
