There are times when seemingly minor issues can negatively affect mold cooling. Here are some causes of inadequate cooling that I have seen. Air Lock Air bubbles within cooling lines can restrict flow through the lines, which, in worst cases, can cause “waterfall flow,” resulting in “air-locked” cooling channels. Any high points in the cooling [...]
There is a growing demand for injection-molded micro parts, which is closely linked to the ongoing miniaturization of medical devices, electronic circuit boards, connectors, hearing aids, bio-absorbable implants and precision healthcare devices. The automated mass production of these high-cavitation, micro-molded plastic parts — often in the tens or hundreds of millions —leaves little room for [...]
For moldmakers, new product development (NPD) projects represent both exciting opportunities and potential pitfalls. These projects offer the chance to work on cutting-edge designs for globally recognized brands, but they also come with unique challenges that can strain customer relationships and project timelines. In the moldmaking world, NPD isn't limited to entirely new products. It [...]
From specialized cooling component materials and conformal cooling inserts to standard machining practices employing new mold components, mold cooling has evolved and increased in efficiency in recent years. Historically, mold cooling systems were designed to circulate water or other media through the base plates, but not necessarily within the cavities. Newer technology creates optimized circulation [...]
With the proportion of free-form surfaces increasing and the precision requirements for mold processing rising, manufacturing molds of high quality and securing the stability and quality during production has become vital. 3D scanning technologies are a game changer in these processes. Mold Design with 3D Scanning and Reverse Engineering Reverse engineering aims to reproduce an [...]
Automation is an essential part of machining and profitable manufacturing. Mold builders striving to compete at the Industry 4.0 level must focus on embedded sensors, software and other technologies to collect and analyze data to improve decision-making. These technological improvements lead to increased speed and efficiency, predictive maintenance and self-optimization of the manufacturing process. Moldmakers, [...]
Traditionally, ballnose end mills were the go-to for smooth surface finishes. However, their limitations, especially for extensive surface finishing, have become increasingly apparent. The small stepover of a ballnose end mill, typically between 3-5% of the tool diameter, results in limited material contact. This necessitates more passes to achieve an optimal surface finish, leading to [...]
A guided ejection system prevents gravity from transferring the weight of the ejector plates onto the connected mold components. This is the support function of the system. They will also help prevent the ejector plates from cocking and binding, which is often caused by the machine ejector rods not being the exact same length, or [...]
Everyday mold builders face various challenges as they tackle each new mold project that enters the shop. Whether it involves engineering, building, maintaining, or repairing molds, this industry’s dedicated technology suppliers offer solutions. Here are some insights and instructions to help your team through four specific challenges. How to Reduce Risk in Plastic Part Design [...]
