Plastic Injection Mold Making

图片
Plastic injection molds are typically constructed from hardened or pre-hardened steel, aluminum, and/or beryllium-copper alloy. Steel molds cost more, but are often preferred because of their high durability. Hardened steel molds are heat treated after machining, and they are by far superior in terms of wear resistance and lifespan.   Many steel molds are designed to process well over a million parts during their lifetime. For lower volumes, pre-hardened steel molds provide a less wear-resistant and less expensive option.   Aluminum molds, on the other hand, can cost substantially less, but they typically are ill-suited for high-volume production or parts with narrow dimensional tolerances. Nevertheless, aluminum molds can economically produce tens of thousands to hundreds of thousands of parts, when designed and built using computer numerical control (CNC) machines or Electrical Discharge Machining (EDM) processes.   Copper alloy inserts are sometimes used in areas of th...

What Causes Short Shots in Injection Molding?

图片
    Original equipment manufacturers (OEMs) can encounter many problems when producing components, including short shots. A short shot occurs when a  plastic injection molded  component is incomplete because the molten plastic has not filled the entire mold cavity. In other words, there is a portion of the part where there is no plastic. For example, a short shot could cause a missing prong on a plastic fork.   Causes and Remedies for Short Shots There are several reasons short shots can occur. The remedy depends on what the cause of the short shot is, in each particular case. Some of the most common causes and remedies for short shots are:   1.  Material Is Too Viscous Viscosity in plastic is the resistance to flow that the plastic faces when it is melted. When a material is low in viscosity, it will flow quickly, filling all of the mold cavities before cooling begins. When a material is high in viscosity, it may flow too slowly to fill a detailed mol...

6 Major Advantages of Plastic Injection Molding

图片
  Plastic injection molding  is an extremely versatile method of producing plastic parts and has multiple advantages over other methods of plastic molding. Not only is the process simpler and more reliable than others methods, but it is also extremely efficient.Let's take a look at the top six advantages of this process:     1. High Efficiency- Fast Production There are several good reasons that plastic injection molding is known as the most common and most efficient form of molding. The process itself is extremely fast compared to other methods, and the high production output rate makes it even more efficient and cost-effective. Speed depends on the complexity and size of the mold but only about 15-120 seconds pass between each cycle time.   2. Complex Part Design Injection molding can handle extremely complex parts, and uniformity, as well as the ability to make millions of virtually identical parts. To optimize the effectiveness of high-volume injection ...
