NPE 2024 Set to Showcase Solutions for 6 Key Moldmaking Trends

As we put together our NPE 2024 Exhibitor Technology Showcase (see pages 38-55 of the April 2024 digital issue), we asked exhibitors to share the most significant trends they have observed since the last NPE in 2018. Following is a list of six trends that highlight the evolving nature of moldmaking and plastics:

1. Technological Advancements for Efficiency and Speed: There is a continuous drive for efficiency and speed to market, with companies offering comprehensive solutions to streamline processes and reduce downtime. For example, the use of ERP systems for integrated business management, 3D printing for cost-effective testing of new designs and improved cooling efficiency through conformal cooling, laser technology for 3D texturing, surface structuring, digital watermarking, electrification, digitization, and automation for repeatability and stability in both moldmaking and molding operations. This includes innovations in simulation, process monitoring, predictive maintenance, melt delivery systems, venting, high-temperature molding applications, mold changeovers and much more.

2. Education and Training: The industry continues to face a shortage of skilled labor. Companies are looking for ways to mitigate this challenge through automation, simplifying processes and improving ergonomics. There is an emphasis on training in CNC cutting, grinding, specialized grinding and EDM to help operators continually improve their skills. Educational institutions are adapting to industry needs, with courses focused on automation and hands-on experience in mold design and manufacturing. The industry is also adopting technological advancements like artificial intelligence (AI), machine learning and virtual reality in eLearning, providing personalized learning experiences and improving accessibility and inclusivity in training.

3. Vertical Integration: Mold builders are offering more services, including production molding capabilities and automation concepts in parallel with mold design to improve project timelines and address manufacturing issues early in the process.

4. Digital Transformation/Data-Driven Decisions: There is an increasing reliance on data-driven decisions to validate manufacturing strategies and make informed adjustments, not just on the production floor but in the toolroom as well. This trend requires using data to track and keep historical information on mold building and molding processes. Some key areas of development include AI, in-cavity sensors, mold monitoring and data security and ERP that integrates data from all aspects of the business — CRM, estimating, BOM, scheduling, accounting and HR. This also includes virtual meetings, video chats and digital data collection processes, which became even more important during the pandemic.

5. Part Complexity: Industries such as medical and electronics are requiring smaller and smaller parts and parts with more complexity, creating a need for smaller diameter core pins, including micro pins, and requiring innovative moldmaking techniques such as conformal cooling and new metal powders with higher thermal conductivity and toughness.

6. Sustainability and Environmental Responsibility: There is a growing focus on sustainability, leading to the development of eco-friendly materials, improved recycling technologies and more energy-efficient manufacturing methods. For example, biodegradable and bio-based plastics, increased demand for liquid silicone rubber products due to their bio-compatibility, heat and chemical resistance, hot runner systems and insulation and dry ice blasting for mold maintenance.
