Side Cores What are the best methods for releasing severe threads or cuts? Do side cores, splits, or other methods work? In addition to the added complexity of the mold structure, adding any of these features will significantly increase the…
Surface Finish of Injection Molding Molded components are prevalent in nearly every industry, from highly aesthetic housings to internal components which do not require fine polishing. Individuals do not pay much attention to how the surface of these components is…
The selection of the correct provider is essential in the process of manufacturing products with the injection mold. In order to warrant the smoothest project possible you must make sure you ask the right questions and help in providing complete…
Injection Molding Material Drying [toc] In some materials, moisture can be absorbed by them from the atmosphere, which can cause the material to hygroscopic. When relatively damp materials are injected into a mould, they become splashed, splayed, or cast with…
An Overview of the Use of Plastic Products We need to look at how the polymer pellets are produced to understand the full life cycle of the process. It is at the stage of production that the overall process of…
8 key considerations for injection molding design Plastics are formed and shaped similarly to metals. It is necessary to consider 3 components when determining the appropriate material on how to design an injection molding: (a) functional requirements, (b) long-term consequences…
In 1953, Toyota Motor Company implemented the just-in-time (JIT) production concept in a large scale to reduce waste of capital, manpower, and materials in manufacturing. The concept originated in the United States. The JIT approach aims at: Just-in-time delivery of…
[toc] Various Plastic Molding Process There are many similarities between the plastic molding and metal molding. A liquid or semifluid state of plastic is formed by heating and pressing it into a mold. The following sections provide an overview of…
Besides producing plastic parts of very complex geometry, injection molding can also mean high production rates. Materials such as thermosetting and thermoplastics can both be used in the process to produce products that meet a variety of end-use needs. A…
The most common and one of the most challenging injection molding defects are weld and knit lines. Bubbles are caused by melting flow fronts colliding in a mold cavity. In spite of its cosmetic attributes, a bad knit line can…
