Wear due to the abrasiveness of the material adds to the maintenance frequency a tool requires. Filler and additives are commonly used today to enhance part performance.
Here are a baker's dozen checkpoints for minimizing problems and maximizing efficiency and uptime in the operation of your hot runner: 1. Determine whether you need grounded or ungrounded thermocouples for your temperature control...
Don't let this happen to you: Leaking nozzles are a common and messy problem that comes from improper setup and operation. Compression nozzles leave room for the expansion that occurs with excessive process temperatures and absorb it without placing stress on the components.
Early adopters of mold monitoring systems are already tracking their molds in real time to determine maintenance needs and monitor output, and therefore ensure that production requirements are being met. This enables them to proactively address issues before they become major problems that impact the supply chain.
One way injection molding companies can use the data provided by a mold monitoring system is to plan and schedule PM for molds, even at multiple manufacturing plants. This offers the shop real-time visibility of current and upcoming PM needs for its molds.
Mold manufacturers and molders can realize multiple advantages by employing these concepts within a mold monitoring system created specifically for production tooling. Such a system consists of three components. The first is a mold monitor—a small, low-cost, battery-powered device that is installed on a plastic injection mold.
Not only injection mold temperature determines melt temperature as it moves quickly through the mold. The melt temperature itself as it starts its journey through the injection mold (self-evidently) is the reference point. Speed of injection, particularly in thin sections, is of huge influence, as it will determine the degree of shear heating.
Many engineering materials like PBT (Polybutylene terephthalate) have a tendency of out-gassing. The best practices that I have to date are: Add 10mm wide vents spaced 30mm from each other all the way around parting line. Always follow the recommendations of the material company for vent depth.
