A machining method typically used for hard metals, Electrical Discharge Machining (commonly known as “EDM Machining”) makes it possible to work with metals for which traditional machining techniques are ineffective. An important point to remember with EDM Machining is that it will only work with materials that are electrically conductive. […]
EDM refers to wire electrical discharge machining. Wire electrical discharge machining or EDM is a metalworking process with the help of which a material is separated from a conductive work piece, by means of electrical erosion. […]
CNC machining is short for computer numerical control machining. It refers to a computer controller that reads code and instructions and drives a machining tool in order to make a product according to specific requirements. Imagine a robot that can make several different products based on a specific set of instructions given to it. [...]
The Rapid Injection Molding process can produce parts within certain limits of size and volume.The maximum part size depends upon part geometry and material, but here are approximate guidelines: […]
A) Part Strength and RigidityStructural integrity and part stiffness are major advantages for conversion to Gas Assist. Flat, relatively thin wall parts can be made rigid with the addition of a gas channel or channels where allowable in the part, with accommodation for proper filling of the cavity. […]
1.New Tooling New tooling considerations involve only a few items that are not part of a conventional tooling design. Quality input is imperative to determine location and shape of gas channels and for design advice regarding ribs, bosses and heavy sections of the molded product. […]
Different techniques are often employed to produce a part prototype. Choosing the best solution to meet customer requirements can sometimes seem confusing. Makino’s application engineers created the following process comparison to demonstrate several approaches that might be considered for a cell phone mold application. […]
There are no inherent disadvantages to the Gas Assist process. There are, however, a few circumstances where it would not be recommended. […]
1) Process Basics Gas Assist Injection Molding is a process enhancement to conventional injection molding, involving the injection of high-pressure nitrogen gas into the resin melt-stream immediately after injection of the resin. […]
The process cycle for injection molding is very short, typically between 2 seconds and 2 minutes, and consists of the following four stages: […]
