Some experience about the milling of hardened steels

Careful consideration of the entire machining system will improve milling of hardened steels.

To maximize productivity and reliability, mold shops often machine a large portion of their products from hardened steels. Historically, hardened steels have been rough milled at low feeds and speeds, with large depths of cut and stepovers. […]

The solution of improving the molding quality of large injection-molded parts

For large injection-molded parts, a servo-driven valve gate system can improve surface finish and part performance.

The art of sequential molding has proven to be a beneficial process in many markets. Automotive suppliers are one of the largest users of this technology, especially for the production of plastic parts with Class A surface finishes. Sequential molding is used to reposition or remove weld or knit lines from critical areas of the parts. These conditions occur when melt flow fronts collide in a mold cavity.  […]

How to select the appropriate aluminum alloy for your mold project

If you opt to use aluminum for your next mold project, it’s important to select the appropriate aluminum alloy. Alloys are created when elements including copper, magnesium and zinc are added to the base aluminum. Each added element contributes individual beneficial properties that will improve the aluminum. […]

How to select welding wires for aluminum alloys

Different aluminum alloys require differing welding wires in order for successful welding to be achieved. Characteristics of the wire should match those of the specific alloy on which it will be welded, and the wire’s color-matching ability, strength and effect on HAZ should also be considered. Additionally, the welding wire must have a melting temperature similar to that of its base material in order for the most effective welding to occur. […]

Introduce Repair Techniques in mold alloy welding

Once the proper wire has been selected, focus must shift to the proper technique for mold alloy to be welded. This is the largest contributor to a successful weld repair. A proper technique involves more than the actual welding; it must also take into account ambient conditions and preheating of the material, which will remove condensation and increase its weldability. […]
