The main causes of weld lines are: When molten plastic encounters inserts, holes, areas with discontinuous flow velocity, or interruptions in the mold filling flow within the cavity, multiple streams ...
Process Control: The Foundation of QualityImproper machine settings are a primary culprit. Here’s what to check:Insufficient Pressure & Time: Low injection pressure, short injection/holding times...
Cracks are a common yet critical defect in plastic injection molded parts. They not only compromise the product's aesthetics but, more importantly, its structural integrity and longevity. This pos...
During the injection molding process, internal stress is inevitably introduced into plastic parts due to factors such as uneven plasticization, crystallization, molecular orientation, non-uniform cool...
Polypropylene (PP) is one of the most versatile and widely used thermoplastics. To achieve optimal results—whether you're molding consumer products, automotive components, or packaging—it's ...
Flash—the thin, unwanted excess of material along mold parting lines or ejector pins—is one of the most common defects in injection molding. Not only does it affect part appearance and dimensions, b...
In mold manufacturing, common methods include machining and electrical discharge machining (EDM). Under certain circumstances, both methods may affect the test molding process and leave specific machi...
Injection molding is a cornerstone of manufacturing for plastic parts, and understanding its core stages is critical for successful mold testing (trial runs) and consistent production quality. The ful...
Core FittingWire electrical discharge machining (WEDM) is generally adopted for the machining of mold cores.Cores without steps: These are the simplest to machine, and high precision can be easily ach...
Molds can be classified in different ways, and each type has its own uniqueness. But what affects test molding the most is the mold structure—it impacts things like pressure loss during processing, t...
