Mold-Vac ? Venting Solutions

We are less than one month away from PTXPO 2025! Here is our list of tips and tricks to make this a successful show for you or your team: ?? Stay in Town Most attendees will be traveling in and hotel rooms in Rosemont fill up quickly! Even if you are local to Chicagoland, our host hotels are in easy walking distance to the convention center. The last hotel room block closes this week! ??Download the App Need to find the exhibitor you are looking for? Curious on when that booth demo was going to be? Have all that information easily accessible by downloading the PTXPO app: https://bit.ly/40RVNTw ?? Learn From the Experts PTXPO is full of opportunities to learn something new. This year, the show is offering a DISCOVERY Workshop series. And the Tech Talk Theater on the show floor has 8 great presentations lined up. ?? See Technology in Action Nothing beats seeing something in person! This year’s show floor will feature eight companies giving live, recorded demos of their latest technology. ?? Have Fun! Last but not least, it’s important for us that you enjoy the show! PTXPO is a great chance to meet new industry colleagues and reconnect with old friends. On Tuesday after the show, meet us at Joe’s Live for food, drinks and live entertainment. Curious of who you'll see? Check out who's exhibiting here: https://bit.ly/4hztBLX Ready to register?

We are grateful for the journey that began in 1988, as we celebrate over 35 years of longevity, growth, and innovation. Our success is rooted in our rich history and resilience, which have allowed us to thrive and adapt in an ever-changing industry. We're thankful for this remarkable journey. Happy Thanksgiving! Sincerely, The Mold-Vac Team P.S. This is a vintage Mold-Vac unit, no longer available to order but on display in our Tech Center & still operational!

One of the toughest challenges in multi-shot lighting is managing trapped gas and air from the second shot, which can burn against the first shot. Due to part design restrictions on seal-off edges, these areas are often thinner and deeper in the tool, making traditional venting methods ineffective. ?? The flow of plastic naturally follows the path of least resistance, causing thin edges to hesitate and create “Reverse V” filling patterns. Fortunately, these patterns can often be addressed early in the design process through localized thickness adjustments (using flow leaders and restrictors). ?? However, even with proactive design changes, challenging part geometries can still create problem areas. This is where Mold-Vac comes into play. By implementing parting line vacuum lines that rapidly evacuate air from the tool, we can significantly reduce air-related defects in these problematic areas. ?? For deeper and more complex venting challenges, stacked or laminated inserts connected to the Mold-Vac system can provide direct air evacuation deep into the tool. Additionally, Mold-Vac’s blowback feature helps keep inserts clean and free of debris, ensuring optimal performance. By combining smart design adjustments and innovative solutions like Mold-Vac, we can overcome venting challenges and ensure higher-quality parts.

Vortex? and Porcerax II? are registered trademarks of Molder's World, Inc., offering innovative solutions to improve molding processes. Incorporating the Mold-Vac system with these complex core pins can nearly double the interval between required insert cleanings, enhancing productivity and reducing downtime. ? This combination effectively tackles the most challenging venting issues: ?? Eliminates Shrink ? Reduces Cycle Time ?? Prevents Burns & Knit Lines ? Eliminates Short Shots ?? Enhances Part Appearance ? Simplifies Tooling & Reduces Costs ? Porcerax II? is a sintered, porous metal heat-treated to 30-40 HRC with 25% porosity by volume. Its interconnected pores, averaging 7 microns (.0003") or 20 microns (.0008"), create an advanced system that allows for gas venting in critical mold areas. ? By using Porcerax II? in specific regions, you can eliminate gas buildup, lower injection pressure, shorten cycle times, and significantly reduce scrap and reject rates—all while achieving superior part quality. ? Porcerax II? is particularly beneficial in hard-to-mold areas where traditional venting methods (like parting line vents or vent plugs) may not be sufficient. Since the material is 25% air by volume, one-fourth of its surface area acts as a vent, providing an efficient, localized solution to vent trapped gas.

Mold-Vac was developed to address a common issue faced by molders: gas and air entrapment, along with plugged vents. Available in five models, each unit is engineered to draw between 20” and 24” of vacuum with precision control. Additionally, every unit is equipped with a unique blowback feature that keeps vented pins clean, helping to reduce tool maintenance and minimize downtime. If DME Company or DME Europe is one of your trusted sources, all Mold-Vac models are offered as part of their Venting Solutions.
