Mold Maintenance training is more and more important

Maintenance training becomes increasingly necessary each time a boomer clocks out for good. Decades of repair experience and mold knowledge are gone in the flash of a retirement party, severely compromising ongoing mold maintenance. This is mainly because many companies do not document critical procedures accurately. […]

Make sure your mold repair procedure is correct

In most welding shops, there is a certain procedure for handling a mold from when it arrives for repair to when it is ready for a customer. At my company, it is a seven-step process that may require adjustments depending on whether we are using micro-TIG or laser welding. […]

How to select properly sized alignment components

Traditionally, designers have relied on a general “feel” or “rule of thumb” to decide which alignment locks to insert within a mold, considering sizes and mounting preference. That’s adequate, right? Maybe not. Selecting an alignment lock based only on gut feel could result in an undersized selection and, down the line, can result in costly mold damage and downtime as well. […]

How to prolong cutting tool life

The benefits of prioritizing expected tool life over price when choosing metalcutting tools are clear, especially in the precision-focused and deadline-driven moldmaking industry. Reputedly, economical tools often provide abbreviated and unpredictable life that results in poor tolerance control and leads to expensive rework. […]

Modern software can help Wire EDM during taper cutting

Software can help compensate for excessive erosion during taper cutting with wire EDM.

Wall straightness or angle accuracy often present a challenge to the machine operator when he or she is attempting to wire EDM taper angles. Several factors within the EDM process affect angle accuracy. These include, but are not limited to, temperature, machine design, material thickness and the machining technology required to cut the desired taper angle. […]

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.  […]
