选择性激光熔化 (SLM) 是一种增材制造技术，可用于生产具有随形冷却通道的模具部件。由于工具插件的重新设计和优化，ABB OY, Drives and Controls 能够极大地减少电缆索环的循环时间。零件的优化几何形状不仅缩短了周期时间，而且还减少了生产中的报废零件。
ABB 是电力和自动化技术领域的全球领导者。该公司总部位于瑞士苏黎世，拥有 145,000 名员工，业务遍及约 100 个国家。
在这项研究中，为工具嵌件设计了六种不同的通道轮廓，其中一种类似于具有传统冷却的零件，以提供与传统制造的比较。通道轮廓针对 SLM 技术进行了优化，考虑到的因素包括面向下的表面角度以减少对支撑的需求、通道之间的最小壁厚以及通道的尺寸和形状。在构建所有各种冷却通道剖面之前，进行了水流和热导率模拟，并且零件在模拟中已经显示出略微不同的冷却行为。
SLM 的使用导致周期时间和生产成本的大幅减少。通过在注塑模具中使用随形冷却插件，将冷却时间从大约 30 秒减少到大约 6 秒，从而能够将循环时间从 60.5 秒减少到 14.7 秒。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.
IoT enabled Fleet Management with MindSphere
In view of growing competition, Gämmerler had a strong need to remain competitive via process optimization, reliability and gentle handling of printed products, even at highest press speeds. In addition, a digitalization initiative also included developing a key differentiation via data-driven services offers.
Premium Appliance Producer Innovates with Internet of Everything
Sub-Zero faced the largest product launch in the company’s history:It wanted to launch 60 new products as scheduled while simultaneously opening a new “greenfield” production facility, yet still adhering to stringent quality requirements and manage issues from new supply-chain partners. A the same time, it wanted to increase staff productivity time and collaboration while reducing travel and costs.
Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
Integration of PLC with IoT for Bosch Rexroth
The application arises from the need to monitor and anticipate the problems of one or more machines managed by a PLC. These problems, often resulting from the accumulation over time of small discrepancies, require, when they occur, ex post technical operations maintenance.
Data Gathering Solution for Joy Global
Joy Global's existing business processes required customers to work through an unstable legacy system to collect mass volumes of data. With inadequate processes and tools, field level analytics were not sufficient to properly inform business decisions.
