What is wire cutting?
EDM wire cutting uses a metallic wire to cut a programmed contour in a workpiece. Extrusion dies and blanking punches and various other forms of jigs and fixtures are often machined by wire cutting. […]
What is EDM ?
The EDM is derived from Electrical Discharge Machining. The EDM process as we know it today started in 1770 with the observations of Joseph Preistly. He noticed that electrical discharges had removed material from electrodes used in his experiments. This is also known as electro-discharge erosion. Later on in the 1940's Soviet researchers developed a [...]
Introduction to insulated runner molding
In the landscape of plastic injection molding, the insulated runner injection mold emerges as a distinct option, introducing unique features to the conventional molding process. 1. Understanding Insulated Runner Injection Molds: An insulated runner injection mold is a specialized tool used in plastic injection molding. It incorporates a runner system with an insulating layer designed [...]
Introduction to cold runner molding
plastic injection molding using cold runner molds, an economical process to produce plastic parts of simple design, or when more than one color part is needed to be manufactured quickly. […]
What is a hot runner system?
A hot runner system is an assembly of heated components used in plastic injection molds that inject molten plastic into the cavities of the mold. (The cavities are the part of the mold shaped like the parts to be produced) […]
Introduction to Dip Molding
Dip Molding is the process where a heated form or pattern is dipped into a heated or ambient temperature material. The pattern is normally dipped into molding material multiple times to build successive layers until the desired part thickness is obtained. […]
Introduction to RIM Molding (Reaction Injection Molding)
RIM Molding (Reaction Injection Molding) was developed in Germany in the 1960’s for molding urethanes. It is used currently for rigid urethane foam, flexible microcellular foam, and rigid microcellular foam. […]
Rapid Prototype General Design Guidelines
General Rapid prototyping is the method for the creation of parts derived from 3D CAD data. The derived part is decomposed into slices (down to 0.003 inches thick), and SLA, STL builds the part a layer at a time. The contour and interior of a slice are created using a laser to solidify liquid polymer [...]
The general rule of Injection Mold Cooling
After the heated plastic is injected into the mold it must cool before ejecting the final part from the mold. The shape of your part will effect how the part cools and must be considered during design. […]
More details about plastic Injection Molding
Plastic injection molding produces plastic parts by forcing molten plastic into a mold where it cools and hardens. In plastic injection molding granular plastic is fed by gravity from a hopper into a heated barrel. […]
