vitrification temperature and molding
but when the temperature is below the vitrification temperature, the polymer is under glassy state, which is hard solid, wherein energy from the molecular thermodynamic movement is low, […]
Simulation technology helps mold design
In the injection molding world, everybody has an opinion about how molds should be gated – how many should be used; where should they be located; and, what size and shape should they be? Much of what is actually implemented into mold designs comes from experience, whether it is from the moldmaker, molder or material [...]
How to mold plastic parts at the low cost
“How can we mold more parts on the same equipment in less time and lower our costs?” is a standard question whose common answers include reduce cycle time and/or improve mold yield efficiency. Surface treatments have been part of this solution and in the last 10 years a new family of coatings—DLC (diamond like carbon)—has [...]
Cylindrical grinding benefits mold making
When we talk about the moldmaking industry, we’re addressing a very large spectrum of applications. The high-volume automotive market aside, we can examine the lower-volume, highly precise molds for medical components, molds for the food and beverage industry, cosmetics and more. […]
how to choose machines for Mold Machining
Consider machine tool capability, intended milling techniques, programming, workholding and toolholding during your cutting tool selection process. […]
simulation technology will benifit mold manufacturing
We all know that simulation technology delivers benefits but, as with most technology, we don’t typically take full advantage of it. Simulation has a lot to offer to mold manufacturing. It’s a matter of recognizing the problems that it can help solve. […]
the longer life of a mold needs a proper maintenance
Regular cleaning and proper maintenance are key to sustaining the life of a mold. If preventative maintenance procedures are consistently and correctly performed, they lower the cost of ownership and increase production quality: a win-win scenario for the manufacturer and the customer. […]
complex molds need a special cleaning processes
A look at non-destructive cleaning processes for complex molds that require the removal of tenacious surface contamination to ensure surface quality and longevity of precision mold and molded part surfaces. […]
How to understand a truly automated CNC machining
Every mold manufacturer is searching for ways to increase productivity, and sometimes that means examining your current processes and changing the way you work. Despite what many think about the dreaded “change” word, if change is implemented properly it can mean less work, not more. An area in which you can experience dramatic results with [...]
How to design a mold with maintainability
DFM. No, not Designed for Manufacturability, Designed for Maintainability. Every mechanical apparatus will eventually need maintenance; it’s a fact of life. Knowing this should be all the impetus needed to motivate anyone with a vested interest to give more than just passing thought to the design of injection mold tooling. The understanding that tools will [...]
