How Conformal Cooling & 3D Printing Are Revolutionizing Injection Molding

In injection molding, cutting down cycle time without compromising quality is the ultimate efficiency goal. One breakthrough that’s reshaping the industry is conformal cooling, an advanced mold design approach made possible through 3D printing.

What Is Conformal Cooling?

Traditional molds rely on straight-line cooling channels created by drilling, which can’t follow complex part geometries. This often leads to uneven cooling, longer cycles, and defects like warping or sink marks.

Conformal cooling changes that. By designing channels that precisely follow the contours of the molded part, heat dissipates more uniformly, reducing cooling time and improving quality.

Why 3D Printing Matters

Conventional machining can’t produce these intricate cooling pathways, but metal 3d printing can. 3D printing allows mold inserts to be built with complex, winding channels that enhance heat transfer and cycle efficiency.

Key Benefits for Manufacturers

  • Up to 60% faster cooling time for increased productivity

  • Higher part quality with fewer defects

  • Lower costs through faster cycles and higher throughput

  • Greater design flexibility in mold layouts

Industries Benefiting

From automotive components to medical devices and consumer goods, conformal cooling is helping manufacturers meet production goals while improving precision and finish.

Why Choose Vexma Technologies

At Vexma, we combine mold design expertise with cutting-edge metal 3D printing to deliver conformal cooling solutions for plastic and metal injection molding, and custom mold manufacturing.

PLA Filament: A Guide for 3D Printing Enthusiasts

 PLA Filament: A Guide for 3D Printing Enthusiasts PLA (Polylactic Acid) filament is one of the most popular materials for 3D printing . It is a biodegradable and sustainable material made from renewable sources such as corn or sugarcane. It is easy to use, widely available, and versatile. In this guide, we will explore the different types, benefits, and applications of PLA filament . Why Use PLA for 3D Printing? PLA filament has many advantages for 3D printing, such as: •  It has a low melting point , which means it can be printed at lower temperatures and does not need a heated bed. •  It has a low tendency to warp or deform, which means it can produce detailed and intricate models. •  It has minimal odor and does not emit harmful fumes, which makes it safer for indoor use. •  It comes in a variety of colors and finishes, which allows you to create colorful and attractive prints. •  It can be easily post-processed , such as sanded, painted, or smoot...

Revolutionizing Tooling with 3D Printed Moulds: A Smarter, Faster, More Agile Manufacturing Approach

  As industries strive for greater efficiency, flexibility, and innovation, 3D printing is proving to be a game-changer especially in tooling. Traditional mould-making is often time-consuming, costly, and rigid. But with 3D printed moulds , manufacturers now have the ability to rethink how they approach production, prototyping, and product customization. A Real-World Example: Precision Tooling for IBHI In a recent collaboration with IBHI, we delivered a custom-engineered mould that combined high dimensional accuracy, exceptional detailing, and a quick turnaround. The mould was designed to meet exacting standards and was produced entirely through 3D printing a process that cut down lead time significantly and allowed for complex design features that would have been difficult or costly to achieve with traditional methods. This project illustrates the practical advantages 3D printed moulds bring to the table not just as a concept, but as a proven solution deployed in real-world indust...
