Steel price is rising
Global steel prices have soared in the past months, far beyond levels that anyone inside or outside of the steel industry forecasted last November and December. […]
What is mold steel polishability?
When it comes to surface finish, it must be understood that any defect that appears on the surface of the mold will be replicated onto the surface of the molded part. If the mold surface contains scratches, pits, welds, uneven textured patterns, etc., […]
Mold Steel selection is very important
Reduced machining time reduces leadtime, lowers labor costs and improves machine use. You can build more tools in less time, increasing revenues. First-rate Mold Solution Co., Ltd experienced what the modified P-21 grades could do to machining time first-hand. President Steven discusses a tool cost analysis he was asked to do in 1992 for the [...]
Different mold steel selection means different cost
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. […]
Weldability is very important to mold maker
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). […]
Structural change in the steel industry
The questions most people are contemplating are: to what extent will steel prices retreat in future months, and will they stay low? […]
Why we select spray-formed steel?
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? […]
Why we need mold cleaning?
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: […]
What is spray-formed steel?
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. […]
Welding is an important option in mold making
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 [...]
