The most discussed topic in the mold building industry today is cheaper tooling from offshore competition. Most often these discussions revolve around unfair low labor costs; however, many mold builders fail to realize that steel selection can play a major role in closing the price gap with offshore tooling. […]
Design changes during tool construction are a fact of life. If the change takes place after texturing or polishing, the tool builder may have to start over. Welding on high carbon steels can cause a dramatic rise in hardness in the area adjoining the welded area-called the heat-affected zone (HAZ). […]
The questions most people are contemplating are: to what extent will steel prices retreat in future months, and will they stay low? […]
One of the issues facing the moldmaker is choosing the right steel. In many cases the choice is made by the customer; however, in many other instances it is up to the moldmaker—Which alloy should I use? Which hardness? What about toughness? […]
The most commonly used method for cleaning plastic injection molds today remains the somewhat antiquated process of scrubbing tooling and plates, one piece at a time. Ask why, and the answers will probably be: […]
Spray-formed steel is steel manufactured using a unique new process technology called the Osprey process. The steel is melted in a crucible using two induction furnaces and is then atomized in a spray chamber under a protected atmosphere. […]
For as long as there have been molds, there has been the need for tool welding. This is to repair or restore components for molds as well as restore surfaces machined or worn out of specification. The exact reasons for using the welding process is to eliminate fabrication of a new part or parts affected [...]
As a result of the spray-forming process, the steel itself shows some excellent properties. For one, it contains very hard primary carbides, which together with the nitrogen from the spray process increase the wear resistance of the steel. […]
If asked to describe the perfect cleaning system for molds and tooling that would allow a significant reduction in labor hours and tooling damage while providing consistent cleaning results, it would meet the 10 criteria listed below. […]
There is an almost endless variety of resins, molds and processes available today, so there is no silver bullet that is effective against all the types of mold fouling and corrosion that attack molds, whether running or racked. An ice blasting cleaning system, however, is a very effective method. […]
