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. […]

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) […]
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. […]
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. […]
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 [...]
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. […]
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. […]
Use rounded corners. Add draft to walls to allow easy ejection. […]
Without the CNC programmer, any modern plastic injection mold making operation grinds to a complete stop-quickly! Just consider for a moment just how many machines use the CNC programmer…. […]
A simple but accurate review on this new Human-Computer Interactions (HCI) angle for promoting creativity has been written by Todd Lubart, an invitation full of creative ideas to develop further this new field. […]
