how to Retain Pin Bushings
A few moldmakers have adopted a new practice for bushing retention using snap rings, which helps create a more robust, more reliable and more easily serviceable mold. […]
Introduction to the 3D printing
Three Dimensional Printing (3DP) technology was developed at the Massachusetts Institute of Technology and licensed to several corporations. […]
History of Rotational Moulding
Rotational moulding has had a long history of development dating back to the Egyptians who used rotational casting processes for creating ceramics. Moulding processes were used hundreds of years ago by the Swiss to make hollow chocolate eggs. […]
History of Plastic Injection Moulding
The injection moulding has seen steady growth since its beginnings in the late 1800’s. The technique has evolved from the production of combs and buttons to major consumer, industrial, medical, and aerospace products. […]
Wire EDM or Electrical Discharge Machining
Wire EDM or Electrical Discharge Machining is a technique used to slice through metal. The technique uses thin brass wire for the purpose and can create intricate profiles with the process. The EDM machine uses spark discharges that are fast, repetitive, and controlled for cutting. This process works with electrically conductive metals. The process is [...]
what is Moldflow Plastic Insight (MPI)?
Moldflow Plastics Insight products are a complete suite of advanced plastics process simulation tools for predicting and eliminating potential manufacturing problems and optimizing part design, mold design and the injection molding process. […]
What is Moldflow Plastics Advisers (MPA)?
Moldflow Plastics Advisers are easy-to-use, 3D solids-based plastics flow simulation tools that allow plastics part designers and injection mold makers to predict the manufacturability and quality of their designs during the preliminary product development stages and avoid potential downstream problems which can lead to delays and cost overruns. MPA is commercially available in two products [...]
what is Moldflow Manufacturing Solutions (MMS)?
Moldflow Manufacturing Solutions are comprised of complete process and production monitoring systems that can be attached to virtually any piece of cyclic discrete manufacturing equipment, […]
how to design snap latches
Snaps allow an easy method of assembly and disassembly of plastic parts. Snaps consist of a cantilever beam with a bump that deflects and snaps into a groove or a slot in the mating part. Snaps can have a uniform cross-section or a tapered cross section (with decreasing section height). The tapered cross-section results in [...]
The typical inserts in plastic parts
Inserts are used in plastic parts, to allow the use of fasteners such as machine screws. The advantage of this is that since these inserts are made out of metal, they are robust. Further, machine threads also allow great many cycles of assembly and disassembly, Inserts are installed using one of the following methods. [...]
