The plastic melt condenses and solidifies before it can smoothly fill in the cavity part far away from the gate or that with thin section, the cavity therefore is insufficiently filled and the shape and structure of the molded products are incomplete, which is intrinsically due to the low fluidity and poor filling capacity of [...]
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. […]
Copper beryllium alloys are heavily used worldwide in the plastic industry in the manufacture of injection mold components that are then used to make containers from different types of plastic resins. It is estimated that 50 percent of the plastic injection industry uses this material for this purpose. […]
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 [...]
Keeping hot runner system costs down is key to efficient injection mold design. Designing standard items into a hot runner system or hot half can help reduce initial material costs and downtime, simplify spare parts ordering, increase design flexibility and system reliability, ease maintenance, and improve product delivery and quality. These standard items include parts [...]
Mold builders can optimize mold performance by taking advantage of advanced process cooling technology. Whether it’s for a precision mold with a relatively low production volume or a straightforward mold designed specifically for a high production run, the importance of incorporating process cooling continues to increase for mold builders. […]
Incorporating multiple-gate nozzles means smaller molds, small presses, a balanced fill rate, reduced residence time, temperature control and design flexibility. […]
As a rule, all plates over 50 kg mass must have lifting holes. If possible, lifting holes should be located so that they are not covered by other components and can be used for lifting even after the plate is partly or completely assembled. […]
There are basically two reasons for placing lifting holes on the face of a plate: […]
The location of these holes can only be determined at the completion of the mold design, after the location for all necessary heating and cooling channels and mounting holes and the shape of the mold part are finalized. It is usually best to provide the handling holes as close as possible above the center of [...]
