Consider the Resin for Plastic Injection Mold Design

Posted by Michiana Global Mold on Aug 1, 2017 8:00:00 AM

 

When designing a plastic injection mold, the mold designer must consider the type of resin and the resin properties that will be used in the molding process.  Thermoplastic engineering resins are the most common type of plastic resin used for the injection molding process.   An experienced mold design engineer will take into consideration the various properties of the resin such as elasticity, fatigue strength, shrink rate, resistance to corrosives or high temperatures, and finish such as matte or polished.  

Elasticity and Fatigue Strength

The resin used to mold a particular product is chosen due to its properties.  For a product that needs a rubber like property with some room to bend or give a little in its application, the print may call for a Thermoplastic Elastomer (TPE) with high elasticity properties.   This type of resin is often used in over-molding applications where a vertical press will mold a rubber like finish around an insert, using a shuttle mold design.

The injection mold design engineer must be aware of the elasticity of the resin and any critical areas when designing the tool to meet part specifications.  

Shrink Rate of Thermoplastic Resins

The shrink rate of the chosen resin is extremely important, as the cavities would have to account for shrinkage after ejection while still meeting part specification.   The cooling rate is also an important property for ejection as the part must be completely solidified prior to ejection.

Top Considerations for a Hot Runner Mold

Posted by Michiana Global Mold on Jun 30, 2017 8:00:00 AM

 

If you are considering a hot runner mold for your next injection molding job, you are probably weighing the benefits versus the costs.  A hot runner mold is typically more expensive to construct, but the return on investment can be well worth it.  Here are some of the most important considerations when contemplating a hot runner mold.

Elimination of Costly Runners

One of the greatest benefits realized from a hot runner mold is the elimination of costly runners.  If the design of a cold runner mold would produce a large runner that would go to waste, a hot runner tool can provide a quick return on investment.  This is especially true if the part itself is small or a micro molding job, the runner is often larger than the molded part or parts.

If your resin is a specialty raw material, it can be even more beneficial to pay more for a hot runner tool, and save considerably by not wasting expensive raw plastic resin.  If the job is projected to support a high-volume production requirement over an extended period of time, the savings in material can be tremendous, especially if you cannot reuse the runner as regrind material.   

A quick cost analysis should reveal the savings in material versus a cold runner tool.  Michiana Global Mold can assist you in determining your cost savings with a hot runner tool design.  

Improved Geometrical Tolerances

In a cold runner tool, the raw material flows through the runner system into the cavities molding the part, as opposed to the hot runner tool where material is injected directly into the cavity through a nozzle.  By injecting material directly into the cavities, the material fills and packs with more pressure thus improving filling into critical dimensions.  

The improved pressure of a hot runner mold can improve the quality of tight tolerance parts requiring critical fill areas.   Michiana Global Mold has vast experience designing hot runner molds with tight geometric tolerances, and satisfying strict customer specifications.
