In addition to providing plastic overmolding services, PMC provides a comprehensive range of other plastic molding services including mold design assistance, modeling, prototyping, manufacturing, and testing. PMC, founded in 1975, works on a range of molded plastics projects for its customers, including:Plastic Injection MoldingMold Design AssistanceOvermoldingInsert MoldingIn-Mold DecorationPrecision MachiningPlastic WeldingThermal FusionPost-Molding DecorationAssembliesPackaging PMC is recognized in the industry for solving complex molding challenges that other plastic injection molders can’t solve. We are able to specialize in this area of expertise because of our certified in-house Master Molders. Since so few plastic injection molding companies have certified in-house Master Molders, most are not able to solve molding challenges or create complex products. In plastic injection molding, cooling rate is the last section of the molding cycle.

What Plastic Do You Use For Injection Molding

Plastic Molded Concepts has expertise in molding with many different engineering-grade resins, including glass filled nylon. Depending on part requirements, you may need post-molding services, such as:Heat treatingSurface finishingWeldingUltra-Sonic WeldingAgency Approval(s) 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. Defined: Plastic injection mold warpage is when the intended shape of the molded part is distorted during the cooling process, causing the part to fold, bend, twist or bow. With today’s machinery, plastic molders are able to inject resin very fast, very slow, or variations of both throughout the process, but within the same injection phase.

How Strong Is Injection Molded Plastic

We serve a wide range of industries requiring mission-critical parts, including aerospace & defense, automotive, electronics, filtration and more. If your parts have stress cracks, you should work with a plastic injection molding company that has in-house Master Molders. Benefits of Engineering Failure Analysis Through Forensic Research in Injection Molding 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. If the operator opens the gate too soon and the product is ejected before the material incurred proper and even cooling time, the operator has shortened the process cycle. An inconsistent process cycle can lead to uncontrolled shrinkage rates, which then causes mold warping.
