Molded Part Surface Finish and Ejection Methods

Injection mold designers must always take into consideration the surface finish required of the finished molded part.  The ejection system in the mold that removes the solidified parts out of the mold cavity or cavities has great impact on the part’s surface finish.  The most common ejection system uses ejector pins which can leave marks on the part, often referred to as witness lines.  

 

An experienced mold designer will position ejector pins in order to place witness lines in an area acceptable to the part print.  The ejection system and ejector pins are housed in the B side of the mold, extending into the cavity during ejection then retracting back into the mold.   Restrictions on ejection must be apparent prior to mold design, if ejector pins cannot be used without damaging the part, lifters can be utilized for proper ejection.  

 

The injection mold design must correspond to the ejection pattern and stroke of the press.  Michiana Global Mold is an experienced injection mold maker with in-depth knowledge of designing various ejection systems to meet customer specifications.  We use CAD/CAM Unigraphics software to design and develop a layout for the ejection system prior to cutting steel.   

 

In some cases, ejection systems must be designed around robotic arms that reach into grab the parts upon ejection.  These robotic systems are called ‘sprue pickers’, as sprue is another term for the runner that is also ejected with the part.  Some ejection systems automatically separate parts and runners, so that they do not need to be separated later.  

 

Whatever your part design, surface finish, or ejection system is required, Michiana Global Mold will design and construct a superior mold with flawless ejection for the specified part surface finish.  We are an ISO registered mold making company with an offshore mold making partner in China.  Contact us today for a FREE design consultation and to speak with a skilled mold engineer.

Benefits of an ISO Registered Mold Shop

 

There are several benefits to having an ISO Registered mold shop for construction of plastic injection molds.  Injection mold suppliers today are expected to meet tight tolerances, and even tighter deadlines.  With just-in-time delivery, this leaves no room for error.  

Plastic injection mold suppliers must follow a detailed checklist to ensure that all issues are addressed ahead of time, prior to cutting steel.  When Advanced Product Quality Planning (APQP) is performed, critical issues are brought to light prior to mold construction, thus ensuring a quality job the first time.

In addition to APQP, ISO Registered injection mold suppliers must consider all inputs into their process, and evaluate their effectiveness of reaching the process goals.  All goals should have quantifiable measurable data, and those goals must be audited internally and externally.  

Any deviations from the course of satisfactorily attaining your goals are required to be explored with corrective actions, or an 8D response.  These requirements ensure that all processes are meticulously followed, resulting in a consistent process, which is required for consistent quality product.  

Many injection molders are required to be registered to ISO standards, especially when supplying industries that require a high level of consistent quality product output.  When injection molders supply the automotive industry with precision components, they must rely on a top-notch, quality driven mold construction shop.  

This is where an ISO Registered mold maker will add value to your supply chain as already having went through the rigid requirements of documenting and auditing their processes.  An ISO Registered mold maker will know exactly what is required in order to satisfy the rigid requirements of top of the tier automotive suppliers such as Ford, GM, Toyota and Honda. To learn more about the Benefits of an ISO Registered mold making shop see our recent Blog on the Benefits of ISO Registration.
