I remember those days when my parents would tell me to get a college degree and become someone to be proud of.  Wow, what pressure!  I just couldn’t see myself sitting behind a desk all day, every day. It all sounded so boring! Poor specification & improper material selection is the leading cause of failure in plastic injected molded parts, followed by improper plastic injection mold design and processing practices. When it comes to selecting overmolding materials, the most critical factor is making sure the materials are compatible. 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?

How Much Does Plastic Injection Molding Cost

Part specifications you’ll want to detail in your plastic injection mold design include:Part SizePart GeometryWall ThicknessDimensional TolerancesNumber of CavitiesPresence of Sharp Corners or RibsPresence of Holes and CoresApplicable InsertsElectrical RequirementsApproximate Part Life ExpectancyOther Needed Secondary OptionsStrength Customers come to PMC because they know we’re able to meet the most demanding tolerances and specifications. They also know we’re dedicated to moving their products into the market as quickly as possible without compromising on quality. Plastic gears used to be found in very limited applications due to the uncertainty around their response to moisture, temperature, chemicals and certain other elements. To discuss your injection molding challenges, reach out to one of our experts: Some parts may require brand compliance, which may include color, imprints, logo, labeling, packaging, etc. It’s important to understand any brand identity requirements prior to starting the plastic injection molding process.Does your part require a particular surface finish?

What Is The Date Circle On Injection Molded Part

If you’re changing plastic injection molding companies, it’s extremely important to include your product’s molding historical data in the transition process. Inadequate gate size restricts the flow rate of the molten resin as it tries to pass through. If the gate size is too small it can cause the plastic filling rate to slow down enough to cause a huge pressure loss from point-of-gate to last-point-to-fill. This restriction can cause physical stress to the molecules. This stress is released after injection, which results in mold warp. Aesthetics need to be addressed as part of the plastic injection molding design process. Below are some of the top questions to consider when dealing with aesthetics:What is the size and shape?
