Plastic Injection Part Design with Ribs and Bosses

Ribs are often used to add strength and stiffness to plastic parts in critical areas or geometric designs where thin walls exist.  This makes the part stronger with added support but can also cause sink marks on the exterior side of the part, where the rib comes together to meet the main wall in the part design.  When using ribs to add support, remember the general rule that the rib should not be more than 60% of the wall thickness.  Adding ribs to an injection mold design will increase costs, and may require EDM processes.  

 

Working with an experienced injection mold manufacturer will give you the best value for your investment.  Skilled journeyman mold makers and experienced injection mold design engineers will have the best knowledge of where to place ribs for added support and how this will affect the tool design, and the cost.

 

Mold making companies today can provide you with a two-dimensional computer aided design to show you exactly how your injection mold will produce the required plastic part, and alert you to any problematic areas ahead of time.  

 

Bosses are a very common feature in many plastic parts, and comes from the word emboss, which means a raised stamp or design, standing out on the surface.   Bosses that are designed with too thick dimensions can cause sink marks similar to the use of ribs.  Utilizing the proper ratio of ribs to bosses a molder can reduce or eliminate unsightly sink marks caused by either feature.  

 

Ribs used to connect boss areas to a side wall can add strength while avoiding sink marks.  Sharp corners are another area where excessive stress can concentrate and adding small radii feature in this area can strengthen the corner and reduce excessive stress.

How is a Shuttle Mold Used?

 

 

A Shuttle mold is a mold system with one A side, and multiple B sides.  This is used in a vertical clamping press, as opposed to a horizontal clamping press.  A vertical clamping press is used for over molding, also referred to as insert molding.

 

Insert molding occurs when plastic is molded around an object such as a metal or even another plastic insert.  A shuttle mold system is used on a rotary table press so that there are two, three or sometimes four bottom sides, rotating around on the table allowing an operator or a robot to place the insert into the cavity in the mold.  When the bottom side spins around, the top half of the mold will come down vertically clamping onto the B side to mold plastic around the insert.  

 

This system can be labor intensive requiring an operator to load inserts, and unload molded product, unless the job is set up with automatic robots for this purpose.  This is different than most horizontal molding processes in which the there is one A and B side of the mold, sliding on a horizontal plane, coming together for the injection molding process, then the parts are automatically ejected with an ejector system falling into a desired location, usually a bin or box underneath the mold.  

 

Most horizontal injection molding jobs are fully automatic once the mold is set in the press, some can even run in a lights-out situation if automated auxiliary equipment is established.  A vertical molding press with a shuttle mold system typically employs an operator, although they can also be automated.  

 

Some examples of insert molding would be electrical wire harnesses that are partially encased in plastic, or even knives or silverware that have plastic molded around a metal object.   Shuttle molds are used in plastic injection molding for various industries including Electronics, Consumer Goods, Automotive, Aerospace and Military / Defense industries.  

Michiana Global Mold has experience constructing precision shuttle molds, and virtually any other type of plastic injection mold base used in various industries.  We are a valuable supplier to the Automotive industry with complex tools meeting tight geometrical dimensional specifications.  Contact Michiana Global Mold today, and ISO9001:2015 Registered mold maker.

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.  

Michiana Global Mold has more than 500 years of combined experience designing and building injection molds for various industries.  We utilize advanced technology combined with skilled journeyman moldmakers and vast resources to construct quality tools for injection molding of thermoplastic resins.
