Traditionally, one of the largest barriers to achieving high surface finish has been vibration. Considering the whole spindle system, vibrations can be induced by several different components. Whether looking at the concentricity quality and balancing of the tool, toolholder system type, spindle interface or interface diameter, there is an intrinsic vibration existing within the system [...]
Machine controls today allow for extensive dynamic tuning of machine performance. The most common values to look at when considering machine dynamics are speed and acceleration. Equally important as each of these is jerk. […]
A new technology exists that ensures proper grease distribution to the spindle bearings over long duty cycles. This new grease lubrication system applies a shot of grease every 70 hours to each of the spindle bearings to ensure proper lubrication. […]
1. Manage 3-D data references between mold bases, parts and assemblies.Even though 3-D CAD systems provide distinct advantages in the development of molds, […]
In selecting a hot runner system for your medical application, make sure your hot runner supplier has a good understanding and experience with the resin you will be processing for your application. Most hot runner suppliers can produce sample parts and may be able to run your resin in a test mold. Don’t be bashful [...]
What constitutes a more efficient cutting tool? That of course depends on the type of tool you are currently using and on the application, but there are three factors to look at: […]
Every molder and OEM has the same goal: to optimize production of quality parts and get their products to market on time. There are several strategies out there that will help to accomplish this goal, and many times the molder or OEM looks to his or her mold builder to lay the foundation for a [...]
Multi-tasking is one technology that has been around for a while, but has only recently become the hot topic as more shops discover their uses. In fact, many companies who previously never thought about getting a multi-task machine have done so or are thinking about doing it for the gains in productivity they offer. [...]
Design for Manufacturability (DFM) is the general art of creating new designs in such a way that they are easy and inexpensive to manufacture. Anyone who has ever designed a product to be injection molded likely learned along the way that small changes to the design could significantly impact the cost, time frame and overall [...]
Today’s moldmakers are finding great opportunity to modernize and speed the process of mold (and product) verification, while at the same time boosting their ability to collaborate globally with their partners and suppliers. One increasingly popular solution comes from combining model-based inspection software and portable inspection devices. […]
