When more than one gate is required within a system, the question of balance is raised. When running multicavity molds, it’s important that all the gates perform identically. This is especially true when molding highly toleranced and thin wall components. […]
Fierce competition within the plastics industry is driving productivity and the need to do more with less. These same forces demand a very fast part-to-production leadtime to win OEM molding programs, and, going beyond these challenges, require mold builders and processors to qualify and test molds within very tight time parameters. […]
To be able to approach CAD data translation well, the product you select needs to have robust kernel technology that allows the transfer of data based on known rules and tolerances of each specific CAD system. […]
After a new mold has been manufactured and inspected from cavity to cavity to tolerances within fractions of a millimeter, it is sent to the shop floor. This is where the true test of the mold’s quality can be realized. […]
Molders are constantly looking for ways to produce consistent, high-quality parts while maximizing output and uptime. One of the best ways to achieve this is through the use of an effectively engineered mold base. […]
Even though the underlying modeling technology is similar among various CAD systems, there are a number of significant differences in how 3-D objects are defined. CAD systems must select various tolerances that best suit their mathematical algorithms for generating generally shaped surfaces, surface-surface intersection curves and positions in space. This must be done because computers [...]
Many industries place strict requirements on the acceptable level of surface defects and imperfections that may appear on a plastic molded part. Such conditions often apply to critical components for the medical and pharmaceutical industries as well as for the manufacturers of lenses and other optical devices. […]
With requirements for lowest weight, highest thermal conductivity and ease of machinability, tool and mold applications are a natural opportunity for aluminum. Aluminum producers have responded with often-proprietary and trade-named products tailored to meet the diversity of challenges presented by these applications. […]
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. […]
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., […]
