Filter for nozzle with a plastic toy next to it. Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today.
Multi-material injection molding (MMM) is the process of molding two or more different materials into one plastic part at one time. [1] As is the case in traditional injection molding, multi material injection molding uses materials that are at or near their melting point so that the semi-liquidous material can fill voids and cavities within a pre-machined mold, thus taking on the desired ...
Draft angle design is an important factor when designing plastic parts. Because of shrinkage of plastic material, injection molded parts have a tendency to shrink onto a core. This creates higher contact pressure on the core surface and increases friction between the core and the part, thus making ejection of the part from the mold difficult.
Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume.. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is required.
This is typically caused by leakage of the material between the two surfaces of a mold (beginning along the parting line [1]) or between the base material and the mold in the case of overmolding. Details
There are several types of molding methods. [5] These include: Casting, the oldest term, covering a wide range of materials, especially metals; Blow molding; Powder metallurgy plus sintering
In the electronics industry epoxy resins are the primary resin used in overmolding integrated circuits, transistors and hybrid circuits, and making printed circuit boards. The largest volume type of circuit board—an " FR-4 board"—is a sandwich of layers of glass cloth bonded into a composite by an epoxy resin.
Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology.
