Design Plastic Injection Molds to Press Specifications

A plastic injection mold designer must consider many factors when designing injection molds, including the press the mold will run in.  Knowing the press specifications is very important in order for the mold to operate properly, and most efficiently during injection molding production.  

Vertical Press Clamping System

The orientation of the clamping system is of course a very important consideration, as this determines whether the mold will open horizontally or vertically.  A vertical molding press is used in over-molding production, also called insert molding because the molten plastic is molded around an object.  An example would be an electrical wiring harness with plastic molded around a portion of it, clamps or even something like knives where the handle is molded around the metal.  

The insert in a vertical molding press can be either steel or even plastic.  A vertical press requires molds for the top and bottom, as a vertical molding press has a rotary table which holds at least two bottom (B) sides of the mold, while the top half (A) half comes down to close on the bottom half molding the part.  

There is usually one top half, and at least two or more bottom sides to the mold, so that when the A side is molding the part on the back of the table, another B side is in front of an operator or a robot loading an insert into the open mold.  Once molded, a robot or operator can unload the over-molded part from the mold, prior to loading new inserts into it.   Constructing molds for a vertical molding press is quite different than for a horizontal molding press, even though the concept is the same.  

Horizontal Molding Press

The most common type of injection molding operation is in a horizontal press, requiring an A side and B side, closing together on a horizontal plane to mold the parts.  When the horizontal mold opens for ejection, parts usually fall into a bin below or are grabbed by a robot and taken to an inspection area.  Most horizontal molding operations do not require an operator at the press, as the vertical over-molding jobs do without automated equipment.   

Horizontal molding presses are very efficient and non-labor intensive, with a top-quality high-performing injection mold, a horizontal molding operation can run for hours in a lights out environment.  

Regardless of whether the mold is for a vertical or horizontal press, the placement of water fittings and hoses is of the utmost importance in designing the tool.  The clamping pressure and press tonnage are also very relevant specifications, in order for the mold designer to calculate the pressure of the molding operation while also considering the material chosen and how it will flow into critical areas.

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.

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.

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.
