In some cases, having plastic injected parts that have been (or will be) molded-in stress can be acceptable. However, all 4 of these key factors (cost, turnaround time, stress/pressure application volume production) need to align. In addition to providing overmolding and insert molding services, we also offer a comprehensive range of other plastic molding services including mold design assistance, modeling, prototyping, manufacturing, and testing. Our in-house Master Molders are technically-trained and certified in plastic mold design, analysis, optimization, troubleshooting and issue resolution relating to complex molding projects. Depending on part requirements, you may need post-molding services, such as:Heat treatingSurface finishingWeldingUltra-Sonic WeldingAgency Approval(s)

What Is Packing In Injection Molding

All materials must seamlessly mate and bond with each other to ensure medical device integrity. The base layer is molded first and the additional plastic layer(s) are molded over and around the original part – resulting in a single, finished product.Overmolding Benefits:Strong Finished ProductLong Service LifeEnhanced SafetyMore Cost Efficient than Post-Molding FabricationOvermolding Product Examples:PCBRFIDPhonesPower Tools Hand ToolsCar Steering Wheels*Special Notes: When it comes to plastic injection molding processes, many people find themselves researching the differences to determine which process is right for their application. One of the most commonly researched processes are overmolding and insert molding. Historical data can also shed critical insights into molding conditions and illuminate solutions to correct inconsistencies and/or inefficiencies.Molding Error Examples: The final common processing defect is improper melt temperature. When using the processing guides supplied by the materials manufacturer you will see a range of temperatures suggested.  This process value is important to making sure that you are not destroying any of the chemistry involved in the making of the final part.  The mold temperature is equally as valuable in the development of stress.  Before you attempt to mold the first part, make sure the resin purges out the nozzle in an even-smooth-creamy-melt for the entire amount of resin that is destined to be injected into the mold.  It’s no good to have a nice creamy melt stream halfway through the injection of the material stream and the last half look like corn-cobbs. This process is already off on a bad start. Smooth is best!What’s the Bottom Line?

A part machined out of cast material will often give you a resulting stronger part. If machining the part includes sharp corners, this could become a trap into the material selection being completely wrong for the molding process.Size In 2016, the use of ABS in electrical/electronic appliance markets resulted in over 2/3 of the world’s total consumption of this engineered resin. Plastic Molded Concepts is a U.S based company that uniquely specializes in molding with engineered resins. We have been thriving in the plastic molding business for 45 years. We have the experience and certified in-house Master Molders, allowing us to take on projects of any complexity.
